I might have something suitable in my bits box. I'll dig them out and measure things shortly.

UPDATE: I found two whitemetal three-spoke handwheels (with the twisty spokes) in cast whitemetal which measure 17 inches in diameter (432mm in new money). Would they be of use?

The sizes shown in the photograph scale to pretty much the same size as the handbrake wheel for fitting in the cab of 7mm Westerns, I hope we all know who makes kits for Wizzos.... cast brass and fettle up quite well.

A Mk.1 with what looks like a fuel tank... and air brakes... please tell more, with pikkies.

regards, Graham

Thanks everyone, they are on the weedspray conversion I'm making. More to follow soon on its own thread.

Heather, are your wheels 432mm when scaled up or actually that size as I'm thinking that's a pretty huge wheel in 7mm?

Cheers

I stuck a scale ruler across one and took a "near enough" measurement, then converted to mills. They're pretty close to the size you want, I think.

The wheels are spares from JLTRT guard's compartment handbrake standards. They'll need the vertical handle trimming off, and perhaps drilling through to mount them nicely. You're welcome to them if you want them. I can drop them in the post tomorrow.

Hi Heather,

Yes please. That'll be great thank you:thumbs:

... any ideas as to the width / depth of the vertical metal strip alongside door openings?
... the anti-corrosion moulding, it's 0.95mm wide by 0.073mm thick in 7mm scale.... for Mk1s & Mk2s...
Looking at photos of Mk.1 carriages which have received the corrosion repairs to the door pillars - and on the assumption that such repairs were applied to all "relevant" door pillars at the same time - then corrosion strips seem to be applied adjacent to all passenger doors of a carriage. What was done with the door pillars adjacent to the Guard's door(s)? I ask because there are some photos referenced from this topic (and from Railwaymaniac's EZ-build topic) which do show the strips whilst such strips appear to be absent on some Flickr shots (where the strips are visible adjacent to passenger doors). And how about the door pillars adjacent to luggage doors?

When corrosion strips were fitted to a carriage, what was done when re-fitting the doors? commode handles for passenger doors? handrails for Guard's doors? Inspection of stock at the GWR (Winchcombe) showed that many carriages had the door hinges and passenger commode handles fixed on top of the corrosion strips. Railwaymaniac has posted a photo of a Brake Coach where the Guard's handrails have been attached to the original bodyside with the corrosion strips cut to fit around the handrail fixing brackets. What was the policy for the repair? What was the practice?

thank you, Graham

There were two different approaches Graham - there were vehicles which had these strips fitted from new (circa 59' on builds) - in general on these the commode handle sat on top of the corrosion strip (the standard commode handle had a small portion milled out of it to allow the handle to sit in the same position as the vehicles not fitted (therefore not increasing the width of the vehicle over the body) Vehicles which had the corrosion strip added later generally had the handle in the normal position with a 'U' shaped section cut out of the corrosion strip to fit around the original handle. Practices varied slightly of course between works & owning region but in general if it was one of the heavier repairs - i.e. a C1 classified repair, all doors were done at the same time but I have seen vehicles that given the strips on the passenger door only during the lighter C3 Classified repairs - as abnormal work (over and above that required normally for that level of repair) In general we always seemed to be doing all doors on both ScR and LM allocated stock.

These look great Tom. Was there a deliberate choice of different frame types made - or is Brian offering the choice? the main bodylight frames seem to represent those that used external rubber glazing mouldings and the BG & Toilet bodylights the plain aluminium frames...

Hi Bob,

As fas as I understand Brian is offering the range of types. These pics are just a selection to show the some of the different types on the test etch.

I have some photos which show the location of the steam heat pipe at the ends of a Mk.1 carriage... and a rough idea as to the position of the steam heat drip valve... and no idea as to the run of the steam heat pipe between the headstocks. Who has included the steam heat pipe run on their model and can offer suggestions as to the routing? In case this question is dependent upon carriage type then I am interested in BSK /BFK / SO coaches (some built pre-1957 and some built post 1957... all as running circa 1985-90).

Photos indicate that the steam heat drain valve is located at the centre of the underframe... can anyone say how far the steam heat pipe is below the solebar at this point? How is the steam heat pipe supported / fixed generally?

I think that the steam heat pipe is 2" - 2 1/4" OD with an insulation layer... probably not Asbestos tape by the 1980s, what material might have been used as an alternative at that time?

thanks all, regards, Graham

The wheels for Mk.1 carriages are either "big" for BR1 / CW bogies or "small" for B4 bogies... those wheelsets have holes in the disc, presumably to allow for cranes to lift a wheelset by attaching hooking "brothers" into those holes.

What size are the holes in the "big" wheels?

What size are the holes in the "small" wheels?

I understand that there are four holes in wheels for BR1 / CW bogies, how many holes are there in wheels for B4 bogies?

thank you, Graham

After a few minutes searching Graham - I presume you're talking about BR Carriage wheels in general - the answer is the same anyway!

the holes were all 2" diameter and for all the BR built MK1/2 stock, four in number (if the holes are present that is - you accurately have them with or without) they were deleted on new wheels (either the centres for wheel/tyre combinations or the "wheel" as a whole in monobloc wheels as on the B4/B5's - the holes were not intended for lifting (it was severely frowned upon for the risk of damaging the wheel - preferring to have them lifted by the axle with fabric lifting straps) however they were used on the early wheel lathes to attach the drive dog's to for turning the wheels for reprofiling (later ground wheel lathes drive the wheels by the tread)

Hi all, there were several three carriage "sets" used on the S&D over the years, does anyone have any set numbers, carriage numbers and indeed the type of carriages used? I am particularly looking for info on a BR(S) green set,
cheers Rob

Interesting and thank you.

When was the design changed to omit the four holes? What might be the earliest date that wheels without holes got used for repair work on Mk.1s / Mk.2s?

For those who are interested in purchasing Easybuild Mk.1 coach kits... a word of warning. All of the Mk.1 corridor coaches use the same floor moulding and a similar "style" of bogie rubbing plate attached to the underframe. Coaches with BR1 and B4 bogies use the same Aluminium turning for the rubbing plate. Coaches with CW bogies use a thinner Steel turning; Easybuild includes the appropriate part with a kit if advised of bogie type when the kit is ordered. However, if you purchase at a show and ask for CW bogies then there is a chance that you may not be given the turning.

We bought several coaches at Telford 2012, some of the coaches needed BR1 bogies, some needed B4 bogies and some needed CW bogies. Easybuild was happy to swap bogies from the contents of a kit for the appropriate "pre-packed" bogie kits and in the melee of the show the need for the thinner turnings was forgotten.

I rang Easybuild today and Mr. Kay is happy to send the "forgotten" turnings. Great, neat and tidy.

regards, Graham

The amendment in the Manufacturing Drawings to delete the 2" holes from the wheel centre's (or the whole wheel in the case of the Mk2 / Integral Wheelsets was typically made in May 1969 Graham from those I've looked at. As to when you would have first seen the change is anyone's guess - it would only have been made once new wheel centres had been manufactured and injected into the main works stores to replace those that were damaged beyond repair. I've no doubt though many would have been withdrawn with the original four hole wheel centres still in use (though of course not necessarily under the original vehicle/bogie)

Here's a typical wheel centre - in this case as specified for the Mk1 CCT with the holes still shown.
