Just a quick update for today.
I started to thin down the Replica tender side frames and didn't get very far before I realised it was going to take far too long and had no guarantee of success. Indeed I soon put the files down and resorted to a disc cutter in the mini drill. This only confirmed my doubts about successfully thinning down to the stipulated thickness of 0.7mm.
So that got put to one side and I decided to make a new set of frames from 20thou nickel silver.
I sweated two layers together then traced out the outline of the existing plastic frames. A bit of elbow grease and a piercing saw duly combined to fret out a rough outline which was then tidied up with files.
Thankfully I had some spare spring and axle box castings in a Mitchell tender kit so these were attached with low melt solder, having first tinned with 145 deg. Slots were fretted out for the wheels in the base and we're more or less there. I've some fettling to do but the wheels are about ready to go in.
