It's been a long while since I found time to write something here. Sorry!!
Since the last update, I have:
1) Completed the chassis and air tested them
2) Made and fitted the ashpans
3) Made the drain cocks
4) Fetched the boilers
5) Made the smokeboxes
Currently, I'm also building a pair of diesels for friends, but hope to get these completed soon so that I have more room to work on the tinks. Then, I'll be fitting and piping up the drain cocks and blast pipes, then it's full steam ahead with fitting the boilers.
