Yesterday and today's work involved setting up the smokebox in the loco frames. The holes were already drilled right through but this brought about the problem of not being able to do up the nuts on the inside under the smokebox.
So a solution was devised of silver soldering some M5 nuts on the inside of the smokebox, the flats and zinc plating was removed by machining off.
The bolts were shortened and the head stampings faced off. The extra unused holes in the frame were plugged up with copper and hammered over and filed flush.
The smokebox and chimney were sand blasted as there was no primer previously and the paint had burned off during silver soldering.
A piece of 1/2" brass angle was riveted with 5/64" rivets to the bottom of the smokebox to support the front deck plate.
The smokebox to boiler engaging ring was roughed out from some left over 4140 tyre material. Still more work to go but Michael spent quite a while at the lathe taking it down to size.
Happy steaming!
