Hi Brian,
Sorry for the delay in response. At the moment i am in the middle of a build of a 3 1/2 inch Jubilee loco to the Martin Evans design. The guys at the club persuaded me to take it on when one of the members brought in a pair of frames, horn blocks etc. part assembled. I have taken it on mostly to learn the skills needed to machine the small parts that make up the beast, rather than a desire to sit behind a live steam loco. When I've finished it, i may well sell it.
I have also recently purchased a Harrison 11 inch lathe, having traded up from a Boxford Model A. Its turning out to be needing a bit of fettling, which i really enjoy, and i think it will be a good little machine when I've got it up to scratch. I've also got a 1943 Bridgeport which i have got going and which i will one day convert to CNC. Not for any reason other than to learn. I learn loads from the guys at the TSMEE and i can see there's much to be gained from many on this forum.
