Building Tender
The tender is constructed in brass sheet, to form the tender side radius’s and flange’s I made a double sided hardwood former I annealed the brass which made the forming of the flanges a bit easier.
The tender is held together with copper rivets, and a reinforcing strap is fixed inside the tender this takes the strain of the tow bar bracket.
The tender is made water tight with Araldite Epoxy Resin I spread this over the internal seams and rivets, by using a heat gun the Araldite turns very thin and it penetrates the flanged joints to form a perfect water tight seal.
I made aluminium formers to form the beading around the tender top and openings, the corner pieces were formed as separate items and fixed first, then the straight pieces were fixed up to them, the beading is held in place with rivets.
Below are the gear guards these were formed over wood formers, I made cardboard patterns to get the size for the gear guards from the gears as fitted on the engine that way I knew the guards would fit when finished and fitted to the engine.
