Gwr Ransome & Rapier 36t Crane In 7mm

[Steph Dale]

Hi Roger,

Nice to see you're here - you must have got my message!

I've just had a quick look through the frets and it appears to have three cab backs. One has only one window, plus there's one for the Turner boiler and one for the vertical fire-tube boiler. In terms of the boiler itself, only the vertical fire-tube boiler is provided (as a rather crunchy brass casting). There is only one set of cab side parts as far as I can make out with a relatively cursory inspection, and they don't appear to have windows in them..

Best wishes,

Steph

What is a crunchy casting? It all sounds very complicated and if it is a 'blow up' I should imagine there are a few hidden issues.....

Erm, well 'textured' - most of the patterns have been produced using some form of rapid prototyping. I suspect it's stereolithography rather than 3D printing, so they'll need a bit of 'work' to get them up to scratch. It's impressive stuff though. Well most of it is; the water tank is really only fit for the bin IMHO.

We'll see where we go with the 'issues', few are insurmountable and the instructions carry several warnings as to the kit's complexity and challenges. The CAD drafting for the etches was obviously done at large enough resolution as there aren't any obvious artefacts of the up scaling.

I asked Ian about the process for producing the gears and the reply was "3D printing of the master". Ian accepts that some of the castings exhibit layering, he remarked that recent 3D-printing has used a different substrate to improve the quality / surface finish.

The CAD drafting for the etches was obviously done at large enough resolution as there aren't any obvious artefacts of the up scaling.

Do we have the same kit? The etches for the wagons have fold lines that are wider than one might expect for a 7mm kit and the "grooves" between the planks of the weight truck are comparable to the width of the fold lines.

 

[Steph Dale]

Are we sure that you and Peter have bought the same kit? The etches for the two wagons have fold lines that are wider than one might expect for a 7mm kit and the "grooves" between the planks of the weight truck are comparable to the width of the fold lines.

Hehe - I don't know, I haven't looked at the wagons! Just out of interest how do they do for thickness? Most etched 7mm wagons seem to have planks which are somewhat thinner than scale. The crane seems entirely buildable to me though...

Steph

 

[Dog Star]

Just out of interest how do the wagons do for thickness? Most etched 7mm wagons seem to have planks which are somewhat thinner than scale.

The prototype jib truck has floor and side rails of steel plate so the etch part is appropriate. The prototype weight truck has wooden sides and ends, here the etch is folded to provide double thickness for the sides and ends. Overall the sides and ends of the weight truck body look reasonable.

I have a more than a passing interest with the cranes concerned since I am the present owner of GWR....

I am more than happy to answer any questions you may have regarding No 2, or any other breakdown cranes for that matter, and supply any additional information, including, within reason, photos of bits of No 2 as it is today.
Roger

Happy to take you up on your offer... starting with an aspect of crane design which we discussed "over there". When the GWR put crane no. 2 into service the crane was provisioned with a jib-rest bogie wagon and a four-wheel truck for the tailweights (aka Kentledge). From photos on the East Somerset Railway web-site I can see that the crane has a jib-rest at this time and there is no sign of the weight truck. A couple of questions please:-
[1] how does the jib-rest relate to the wagon which was attached to crane no. 2 before WW1?
[2] what has happened to the weight truck for crane no.2?

If the weight truck was not preserved with the crane, how are the tailweights moved around at this time?

In discussion with Ian Young at the Reading Trade show last weekend it emerged that Ian was not aware of the prohibition which the GWR placed on the crane being moved with the tailweights in place. The discussion concluded that the kit probably represents, in side view, the crane with the tailweights in place. As we wish to model the weight truck in a "travelling" form I am interested to know the shape / size of the tailweights? What images might you have of that item?

Thank you, Graham Beare

Graham,

The "weight tender" sadly has not survived with the crane, and I think was probably broken up at Swindon not long after the crane was sold in 1975 to the DVLR. There is photographic evidence that it existed in '75, and by that time the crane formation consisted of the jib runner, the crane, the weight tender, and a 6-wheel former milk tank ADM44171 which was used as an auxiliary water carrier. The latter two vehicles have not survived.

In GW and BR(W) days the three vehicles (jib runner, crane, and weight tender) would always stay together except when the crane was actually lifting, and the crane would never have travelled anywhere without the tender. The jib runner supports the jib, and the lockers were used for timber packing. The weight tender carried the (six-ton) kentledge, together with lifting tackle (chains etc) and of course in the very early days all eight, and later four of the propping girders. The ectra four girders were clearly dispensed with quite early in the crane's life, but I haven't been able to establish exactly when. Up to the end, however, any item of tackle of sufficient weight to mean that it couldn't be manhandled was kept in the weight tender, and picked by the crane when needed. For this reason, even when working, the tender was generally kept coupled to the crane.

When the DVLR sold the crane and it was moved back (intially to Swindon), the kentledge did not go with it. When I bought the crane, it was one of several missing parts I attempted to locate, and I did in fact find it round the back of the workshop at Buckfastleigh, where it had been stored for a number of years. The SDR kindly let me arrange for it to be reunited with the crane, and it is now in a smilar location at Cranmore. I do not anticipate that it will be moved again until the crane is operational.

The missing weight tender is clearly a blow to the restoration of the crane and the recreation of the proper set of vehicles, but I am attempting to purchase an ex-BR(E) "Tube" wagon which is visually the most similar wagon available in terms of size and shape - it is the same length, and the only significant difference is that it has two large drop-flaps per side instead of five short ones. It will do the job, if I can persuade the current owner to do a deal of course.

In discussion with Ian Young at the Reading Trade show last weekend it emerged that Ian was not aware of the prohibition which the GWR placed on the crane being moved with the tailweights in place. The discussion concluded that the kit probably represents, in side view, the crane with the tailweights in place. As we wish to model the weight truck in a "travelling" form I am interested to know the shape / size of the tailweights? What images might you have of that item?

Thank you, Graham Beare

I was going to upload a couple of photos showing the crane without the kentledge fitted, and the kentledge itself (prior to removal from Buckfastleigh), but unfortunately it would appear that I cannot do this from the PC I am currently using so we'll have to go to Plan B for the time being:-

The ESR website has a number of photos of the crane without the weight, for example the second photo on http://www.eastsomersetrailway.com/gallery.php?gid=61

The weight occupies the space where the visitors head and shoulders are visible in this photo, and the two slots clearly visible just above are the locations where the securing nuts are fitted to the kentledge bolts. The photo on the frontpage of the BDCA website (www.bdca.org.uk) shows No 3 crane with its weight fitted, and comparison of the two photos should clarify the arrangement. The weight itself is a single cast lump, shaped in plan like a capital "D", approx 9' x 4' x 10".

The reason I asked about the rear cab sheet before, by the way, is because of the origins of this kit. As mentioned by others, this kit has its origin in a 4mm kit produced by a chap in Bristol several years ago. To produce his "mark 1" version of the kit, I believe he subcontracted the production of the artwork for the etches, and one error was the inclusion of two cab windows (as were fitted to DS35) rather than the single window fitted to the GWR 36-tonners. An example of this mark 1 kit can be seen at Pendon, complete with this very conspicuous error. The chap then authorised someone else to reuse the same artwork scaled up to 7mm as the basis of a gauge "O" version. An incomplete pilot was displayed at a show not long afterwards, then the whole project disappeared for some years, eventually to resurface with Sanspareil. I was therefore interested to know whether this highly visual error had been corrected or not!

The original designer (in 4mm) has been working on the mark 2 version of the kit for a long time now, and the mark 2 version is greatly improved over the mark 1. The mark 2 also includes both boiler options, and a pilot build crane can often be seen on a layout at shows called "Maindee East". Exquisite!

Steph,
Returning to the question of "additional" etches for the GWR diagram L11 bogie match (jib) truck... This question has arisen because we have two sets of instructions and those sets are different, also as we have built the body and underframe of the jib truck I can look at the result and note the differences between our model and the prototype. So, before trying to explain the question I think that we ought to establish that we have the same hymn sheets.

If we have the same version of the instructions then the relevant pages are numbered 46 to 53 inclusive:-
pg.46 contents list;
pg.47 etch layout;
pgs.48 & 51 isometrics of body and of underframe;
pgs.49 to 53 assembly instructions (steps 1 to 38).

[this posted amended to correct page numbers]

Graham,

Sounds similar, if not actually identical:
P46 etch parts list
P47 fret layout
P48 isometric view from above (with cast-framed bogie), scrap view of side/brake linkages
P49 castings list at top
P49 - 50 instruction text
P51 isometric view from below. Isometric view of etched ('Alternative') bogie assembly.
P52 - 53 instruction text.

I've not had a look through the frets to try and hunt aout the 'additional' items for the L11, although I know I have them for the cab as I have three backs - the original kit only had two, I think.

Currently working on the research/cutting lists for the other vehicles (jib runners, carriages)while keeping a bit of thinking space free to consider motorising and the LSWR-specific details. I could do with a block of time to get this lot spread out and see what I'm actually doing. I don't like starting builds 'blind' to the end result...

Steph

Steph, thank you for taking the trouble to list the instruction pages for the bogie jib truck; I had made a mistake in the page numbering of my earlier post - we have the same, revised, instructions.

As to the bogie jib truck "extra" parts, I have scanned sections of pages 48 and 51 to show the parts which do not appear on the fret layout (pg.47) so if you have these parts (11, 31, 32-36) then either the corresponding photo tool has been modified since our etch was produced or there is an additional etch. By the way, the part numbers on page 46 do not tie up with either the fret layout (pg.47) or the diagrams (pgs. 48, 51) in respect of parts 11, 31 and 32 (as a minimum).

This extract shows the construction of the bogie with etch for the frame and brass castings for the axleboxes / spring nests. I understand, from another diagram in the revised instructions, that there is an alternative construction using whitemetal castings - what is provided as the alternative parts for the bogie?


This extract shows the construction of the jib rest within the body... our part 11 is a rectangle plate which is soldered to part 10, the result is a ledge upon which sits the cross beam for the jib rest. The vertical platework shown above parts 11, which I think is part 31, is not included in the crane etches which we received in September. So, assuming that you have parts 11 and part 31 as per the diagram, how are those parts supplied in current kits?


This extract shows how the GWR handbrake mechanism is assembled. Starting with part 32, which I think is likely to be an etching and folded to shape, how is this supplied in the current kits? As for the other parts for the brake linkage (parts 33 to 36 inclusive), we have none of this and I am not sure if the parts are cast or etch. Please shine the proverbial torch on the contents of your kit and let me know what you have for the handbrake assembly.


Clearly I shall have to request the missing,"additional", parts from Sanspareil and to that end I shall be appreciative if you can let me have photos of how those parts are provided in your kit. I hope to sort out the rail clamp and jib rest roller castings today so that I can post photos here.

If you have had the opportunity to check-off the gear castings yet, have you got the gear(s) which transfer drive through the crab into the carriage?

regards, Graham

 

[Steph Dale]

Graham,

I think I've found the parts you're after (remembering it was only the crane I went through in any detail!).

First up, the castings - this is the set for both the jib runner and the weight wagon. It would appear that I'm lacking a set of queenposts (at least) and that the brake components are, in fact, cast...:


I do remember Iain telling me that the cast bogies weren't included in the 7mm version of the kit. I'd probably be having a quiet word with ABS or even Jim at Connoisseur if I was going that route.

The etch sheet I've got for the L11 is attached to the fret for the jib, thus:


And it appears that there's only a relatively small number of 'Additional' parts, this fret, which seems to include most if not all of the other items that you were wondering about, so I take it this is missing from your kit:


I also found one of these sprues in the bag of non-crane parts, which I guess is the item you were referring to with the rail clamps and roller. I can see I'm going to have to get a few more of these, including a set for the DJB crane...:


I think that's just about it - have I missed anything?

Steph

View attachment 8503

You do need a second casting for the Queen posts and cross-girder, one casting for each of the wagons. You might ask for a casting of the correct length as ours was about 6mm wider than required for either wagon, the girder does extend beyond the edge of the solebar... not as much as in this instance. I suspect that the casting may be from a GWR Toplight kit.

The jury is still out on whether the handbrake fitting for the jib truck are cast or etch... look at the additional etch sheet in your photo, there are some GWR DC fittings scattered around.

I do remember Iain telling me that the cast bogies weren't included in the 7mm version of the kit.

More is the pity that the revised instructions do not match the contents of the box. What a get-out-of-jail-card if anyone complains about missing parts!!!!!

I'd probably be having a quiet word with ABS or even Jim at Connoisseur if I was going that route.

Thankfully we shall not be going the cast route... we shall need all the room that is available within the etch frames if we decide to motorise the bogie.

The etch sheet I've got for the L11 is attached to the fret for the jib, thus:

Your L11 sheet and the jib sheet look just like ours, so no change there then.

View attachment 8506

OH, BU**ER.

There are more additional parts shown in your picture than I was aware of one hour ago!!!!

There are parts on that extra etching which look very interesting and purposeful.

Please take a square-on photo of the complete sheet so that I can have a "frankandmeanginful" discussion with Mr. Young.

I also found one of these sprues in the bag of non-crane parts, which I guess is the item you were referring to with the rail clamps and roller. I can see I'm going to have to get a few more of these, including a set for the DJB crane...:

Yes that is the sprue which contains the jib rest roller... we have four of those sprues, for the rail clamps, and the roller has been cut off of three of the four. In passing, the sprue does not have the eye-bolt by which the clamp is attached to the headstock... have you got any such castings? (by which I mean.... I need to see if we have any).

I think that's just about it - have I missed anything?

Steph

Missed anything? You can just image a witty comment from one of WTs faithful... "You think that there might be anything missing from a kit which is circa £650.00?

BTW - maybe we ought to arrange for a Crane-sub meet of the WT get together at Bristol.... you show me yours etc..

Thank you and regards, Graham

Not so bothered about these issues - the parts are due to go back to Iain as I'm building mine up as the LSWR version. Reminds me that I need to get in touch with Laurie Griffin to order up the castings I need for the Ex-LSWR tenders that 35s and 37s used as jib runners...

More is the pity that the revised instructions do not match the contents of the box. What a get-out-of-jail-card if anyone complains about missing parts!!!!!

Thankfully we shall not be going the cast route... we shall need all the room that is available within the etch frames if we decide to motorise the bogie.

Hehe, yep. I know there's one gear that wasn't tooled either. A novel motorising solution too.

Here 'tis:
Having a whinge at Iain is likely to be effective, in my experience it can take a couple of goes but the parts always seem to come through.

In passing, the sprue does not have the eye-bolt by which the clamp is attached to the headstock... have you got any such castings? (by which I mean.... I need to see if we have any).

Hmm, not sure I have any and having just had a look at 35s, I'm not sure the clamps themselves are right style for the LSWR cranes anyway. Another part to add to my patterns list then...

Missed anything? You can just image a witty comment from one of WTs faithful... "You think that there might be anything missing from a kit which is circa £650.00?

BTW - maybe we ought to arrange for a WT-Crane-sub meet at Bristol.... you show me yours etc..

I too await Jordan's appearance, I'm sure he'll be along in a minute! For the record the parts I know I'm lacking are three axleboxes, one sheave, a pair of queenposts and three rail clamps. Out of that lot the only real problem seems to be a sheave. Although there are a full set of etched ones provided, I shall still try and get hold of the one I need from Iain.

Have you got a copy of the CD-ROM as well? It's actually pretty useful with lots of photos of No2! And yes it'd be good to catch up at Bristol, although as you've seen this morning my kit is still as flat as the day it arrived...

Did I say anything about Jordan? BTW - you have a different stream of emoticons to those in my post.... you must have pinched the "confused, rant and rage" from the draft post; I changed the little characters after I finalised the captions.

Well you are the lucky one, our initial missing list was two axlebox sprues for the crane, all of the axleboxes and springs for the weight truck, all of the Queen posts, most of the buffers (although to be fair, those supplied were correct for a late period model whereas ours is to be pre-WW1-ish). We do have the CD of photos, puzzling that the prototype photos in the hard-copy instructions are not amongst those in the CD.

The good news, we do have the "extra" etch. When we bought the kit at Telford Ian said that there was an etch sheet which was not required / not relevant. So after the show we carefully un-wrapped what we had and by chance found the weight truck and jib truck first, then the jib and then the rest of the crane. At this point there was one wrapped etch left so we ignored that.... and guess what we found this afternoon? (after seeing your photo we recognised some of the adjacent parts - which we did have - and thought that maybe the sheets had been split and wrapped differently). So, anyone want some frame plates and stretchers for a GWR Broad Gauge 3541 class engine? There is no need to rush as Steph is likely to have a similar set of frame plates!!!!

We intend to go to Bristol if only to talk to ABC about a special-to-type motor unit for the crane travel. I reckon that the bogie under the boiler-end can be motorised and there ought to be enough room to install a decoder within the bogie frame. I hope that the bogie can have pick-ups and hence be self-contained. The big question... one motor driving both axles or one motor for each axle.

If the idea for the bogie is a go-er then we shall have all of the space under the jib-end for a motor to slew the crab and a motor to drive the crankshaft - plus decoders for those motors. Just do not ask where the speaker is going to go.... suggestions on a blank cheque please. Power for the slew and travel motors to come from pick-ups on the three wheelsets at this end.

The wheelsets are 3'1"dia. with ten spokes, from Slater's, and hence have a standard wagon axle. I am not sure if there is an easy way to provide split axle pick-up from these wheels... or maybe the method most likely to succeed in the short term is plungers. Anyone any suggestions?

The instructions for the "alternative bogie assembly" intrigue me - the note "for G A Models" suggests very much to me that this relates to the original 4mm version of the kit (which was produced by G A Models).

Steph, you mention that you have three different cab rear sheets; can you tell me the difference between them? Two I could understand (Turner boiler and Swindon VFT boiler options), but three.....?

The etches/frets do look remarkably similar to the 4mm version.

Roger

 

[Dog Star]

The instructions for the "alternative bogie assembly" intrigue me

There is certainly some intrigue in this kit, particularly with regard to the instructions. The instructions that we received in September do not have the "alternative bogie assembly" wording and there is no indication in the text that the bogie is anything other than an etched frame, with embossed rivets, and brass castings for the axleboxes and spring nest. The instructions which we recieved in December have an illustrations of which an extract has been included in an earlier post.... and it is these instructions which hint at an etched bogie frame with a complete whitemetal sideframe (to be soldered on the outside of the etched frame). Now that we have found the "extra" etch parts the picture becomes a little bit clearer.... there are two pairs of bogie etches. One pair of bogie etch frames are intended for use with the separate axleboxes / springs and one pair of bogie etch frames are intended for use with the whitemetal sides - those pairs of bogie etch frames are shaped differently in the area of the axleboxes.

Which came first? The bogie etch frames for use with separate brass axleboxes and springs is part of the fret for the jib truck whereas the etch frames for use with whitemetal sides is not part of any wagon / crane fret.

the note "for G A Models" suggests very much to me that this relates to the original 4mm version of the kit (which was produced by G A Models).

Unless I am mistaken there is another name on one of the frets... "Artisan Models" if I recall correctly.

Steph, you mention that you have three different cab rear sheets; can you tell me the difference between them? Two I could understand (Turner boiler and Swindon VFT boiler options), but three.....?

Happy to leave this one to Steph.

I was going to upload a couple of photos showing the crane without the kentledge fitted, and the kentledge itself...

The weight itself is a single cast lump, shaped in plan like a capital "D", approx 9' x 4' x 10".

Noting what was written earlier, can you try to post the photos as above?

When convenient to you, what are the dimensions of the kentledge as I shall be making one to include in our model of the weight truck. From what you have explained here and on "t'other place" there must be some cut-outs / holes in the kentledge for the fixing bolts.... are those cut-outs / holes visible when the kentledge is sitting inside the weight truck?

thank you for your help, Graham Beare

 

[Steph Dale]

The instructions for the "alternative bogie assembly" intrigue me - the note "for G A Models" suggests very much to me that this relates to the original 4mm version of the kit (which was produced by G A Models).

As Graham says - as far as I can make out the 'Artisan Models' parts are those tweaked for 7mm - which may mean that Iain's designer had access to the original CAD files. The additional items fret is definately Artisan. I'm notentirely convinced he's right about the bogies though - I thought both sets had rivet marks? I had wondered whether the items on the Artisan fret had probably been tweaked to take 7mm wheels or adapted to Iain's castings. I can't check just at the moment though as I've packed the kit away again.

Steph, you mention that you have three different cab rear sheets; can you tell me the difference between them? Two I could understand (Turner boiler and Swindon VFT boiler options), but three.....?

The third is the two-window style found on 35s that was erroneously included in the early (and 4mm) release. Personally I think it's going to prove rather useful!

The etches/frets do look remarkably similar to the 4mm version.

The instructions are too - there is a pretty-much full copy of the 4mm instructions included, which is how the confusion over the cast bogie comes about. There's then a bit of an introduction and an odd additional note. In terms of the casting lists it's hilarious - there are three covering the crab; none are complete as far as I can make out and on first impressions it's not entirely obvious which is the right one for the 7mm version of the kit!

Here are some photos plus a drawing of the kentledge. Drawing is from the original R&R set but is not very legible. Sadly the original negs seem to have been destroyed in the upheavals of the Maxwell years at R&R and are now lost, so this is the best we have. The photos, taken on two seperate ocasions at Buckfastleigh, show firstly the arrangements for the jackscrews and securing bolts, and secondly the recesses in the top surface. The two large rectangular recesses are to provide clearance for the backstays and nuts, the two slots contain the original lifting points for the kentledge (steel bars included in the pattern and cast into the weight). When these wasted, the two holes nearby were drilled and tapped to allow removable lifting eyes to be used.

Hope this helps,

Roger.
