I wish I had a machine shop! I'm sure I have the skillz but not the tools... I've read over the guide on Sheldon's site before and it seems like a pretty involved job so one for a rainy day when I have a proper workshop haha... Then I can braze frames, and tinker to the heart's content (as it appears you do with that ace chopper etc...)

If you see an ASC - give me a shout (unlikely one will just pop up but you never know) - and good one with that dual-drive score - much cheapness abounds...
