Thanks Norm, Nigel.
Soldered the 2 halves of the tank together, but left the end plates for now, as need access. Much of the work over the last 6 weeks has been doing fiddly parts.
Because this project is all 'Scratch Built'', I want to keep the parts as scale size to the original.
The water outlet/valve is an example and is a simple 'Bottle' style valve running in guides. The joint faces are metal to metal (no seals)-
The faces that contact the inside/outside of the tank are contoured to a close fit.
The weighted lever sits 'over centre' when closed, which applies pressure on the Spring Stainless rod and so on the valve face/seat to improve the water tight seal.
Another view to show the valve/seat and the fabricated outlet with correctly bolted (12BA) flange. This will lead to a Sprinkler Bar as per original-
Hardwood support legs finished to size. A range of steel coach bolts with square/hex nuts, and an alternative flanged outlet elbow for supply to the Traction Engine tank.
The ball on the end of the pump handle is 1/16" (1.6mm) diameter-
Hose hooks are 0.010" (.25mm) shim steel annealed for drilling and bending, then re hardened and tempered to spring grade. Screws are 14BA-
Finally got the wheels done last night and are retained by blind 'Top Hat' caps with a cross pin, as per the full size. Pins are 3/64" (1.25mm) -
Going to be a shame to cover this in paint
