Making the footplate flat
Wary of my experiences trying to rescue the old kit bits, I took a critical look at my Plan B Super D.
In the main, it was very good but I still wasn't happy with the footplate. What should have been a long flat thing was slightly twisted. It's an easy thing to do and the wonkiness was very slight, but still (IMHO) not good enough. However, I reckoned if I could rotate the boiler very slightly around its mounting at the firebox end, all would be well.
A little work with a gas torch released the 100 degree solder but this don't entirely do the job so I cut down with a fine blade along the front face of the 'box and by the time I was 3 or 4mm down, the tube would move.
Before fixing it back in place, I made a jig to hold the footplate perfectly flat. Basically this is a bit of wood with holes drilled in to match the body fixing bolts. The body is fixed to this and construction can continue. And yes, I did check the wood was flat against a mirror first.
I just wish I'd done this a couple of days ago. Never mind, maybe I'll learn for next time.
