Custom Bike Builder

For years Ive seen this guy working in his backstreet workshop, but ive never had the need to go in until now. and how pleased I am that i have.
In the backstreets of Hockley, Birmingham is what seems from the front a little workshop, but once inside is actually a bit of a tardis full of Harley Davidson custom builds, the majority of a corrvett, and some cool subaru off-roader buggy thing in the making.
I popped in to see if they might be able to help with making my headstock and it seems that they can - and then some! My budget and desire to do everything myself is driving me toward making my own frame, but this chap (and i never did catch his name) was suggesting that i might be better off if he built the frame for me. Certainly his TIG welding, pipe bending and jigging facilities do create fabulous frames...... but can i afford it? and am I compromising my experience if i out-source this important part of the job? Plenty of things to think about.
In the meantime I think this chap could be both very useful and interesting :-)
