Hi gents,
Been a while since I've posted here, but I've been a frequent lurker....I've been familiarising myself with basic operations in my little modified unimat 4, so I'm at least au fait with facing, turning, parting off etc.....
My first opportunity arose when I picked up this little Bowman (ca 1930) steam loco, missing its pistons and cylinders.
I decided to try and use the lathe to knock out the missing parts....first I made the cylinders by silver soldering a brass cap onto a piece of tube, and then I turned two pistons to fit - these pistons have two oil groooves, as per standard Bowman pistons. I also cut a portface block.
and after a bit of soft soldering I had
(solder still to be tidied up in this pic)
Drilled the ports using the milling slide:
and to my delight, when I mounted everything to the loc, it came to life! See this little movie:

Now I know this is all extremely simple stuff, but it's my very first attempt at doing something like this, and I'm incredibly pleased it all went right first time....right now I feel pretty good about myself, what a nice feeling! Thanks to this place for giving me the courage to even start! ;D
