Richard's Workbench - T3

    I've got the basic chassis together. It all fitted very well, the biggest part of the time spent was in carefully decusping the components.




    It's set up so that the drivers are beam compensated either side with the bogie pivot being the 3rd part. Again, that took some time to set up just so, filing the arms back on the beams where they rest on the hornblocks.

    I've also done the basic work on the cylinders.


    and I am making the leading springs screw in so that I can drop the front axle with the inside valve gear.

    The supports will take a tap for 12BA.

    I'm back on the T3 workbench, but this time on the tender.

    The basic tender top is made as a box, to which the flares are added. I was not really looking forward to this as a) the flares are not very deep and need to be curved, and b) they need to be parallel to the footplate. The flares are separate as they were on the prototype with a distinct dividing line between the flare and body.

    Fortunately, the curving is relatively easy because the flare is half etched, and the location is dead easy because the kit includes 2 jigs. These are tack soldered to each of the sides and end in turn and the flare fitted.



    Phew! While it did take some time, it was a lot easier than I feared.

    Continuing with my journey through the LSWR locos, I'm back on the T3 for a while.

    The body is built on a fold-up cradle which includes the valances. Care in folding gives a square frame on which to attach the footplate and build the body.


    The boiler and firebox unit and smokebox are built separately and screwed together, only being soldered when totally satisfied (after trial fit to the footplate) that they are located correctly.

    Before the smokebox and boiler can be soldered to the footplate, there are a few details that need to be added first - boiler band cleats on the underside of the boiler


    and the sand operating mechanism on the footplate.


    Cleats are provided in the kit, but I prefer to use Peter Roles castings.

    Some time was expended in making sure the firebox and boiler were a perfect fit to the cab and splashers. Time spent here is well-rewarded as the resulting join is much easier to solder and less stressed and prone to open with subsequent operations. The accuracy of the etchings is first class.

    Here the smokebox and boiler unit is just placed on the footplate - no solder at the moment; that is the next operation. There is a hole on the rear firebox former that engages with a pin in the spectacle plate, and a 6BA bolt through the bottom of the smokebox.

    Boiler unit now soldered on, and it's started to sprout some castings and details.

    A general view - it is so much easier to keep it on the cradle, pretty much until the body is finished.

    Front end detail. The Drummond lamp irons are from Laurie Griffin.


    Rear end detail. I have removed the large whistle.


    The front 2 handrail knobs will be attached with the handrail wire. Once this is done, I can move on to some of the larger white metal castings which will dress the engine quickly.

    It's starting to look a bit more like a loco now.:)

    One of the trickiest bits is forming the handrail at the front. I find it easier (and less wasteful!) to do just the front and as far as the first knob on the side - half-way through it in fact. There's still a lot of on/off checking, but once it's done, it should be pretty much plain sailing from there on the body.

    Beautiful bit of work Richard. A very elegant locomotive, still prefer the superheated T9 though (I am biased towards the locos used on the BR period NCR).

    Hi Chris,

    Thank you. I can quite understand your bias - I share it. A T9 and L11 in BR lined black would look brilliant. It's more by accident than design that I find myself doing a series of LSWR era locos, though I do have a BR T9 to build next year.

    The T9 and L11 are lovely locos, but the T3 and sister T6, X2 and X6 are the elegant ones. Unfortunately being early not many got to BR

    I've now completed the T3 tender. It breaks down into 3 sub-units.

    The chassis:





    The footplate:




    The only departure from the instructions is that I have attached a separate pin for the drawbar.

    Body is next post....

    The tool box top is detachable so I can fit the R/C recharge plug and on/off switch in it.



    The axleboxes and springs are a push fit for the photo. They can be removed for painting. Again, I have used Laurie Griffin cast Drummond lamp brackets.

    Looks great have a couple of this type to build. I must of miss read the drawing for the one on my scratch 0395. I read it that the front tool boxes were on shelves above the coal space.

    There's not actually alot of space for coal above the water tank is there? I assume the poor old firemen of these and the watercart tenders spent a fair while pulling coal forward off the flat areas.
