recently i have been thinking about fabbing a dh frame. it will most likely be a single pivot built around a 9.5X3.0 shock w/8-9 in travel, 4130 cro-mo. I have access to a tig welder, plasma cutter, tubing bender, and i can mitre tubes.
what im wondering is
a)i need a 1.5 ht, can i find some (?) id tube and just clean it up by taking it to a shop.
b)for the bb shell can i buy one somewhere? do i have to get it turned on a lathe or cnc'd? or can i just tap threads into a tube with the correct id(which is...)?
c)where the heck would you find 27.2 id pipe for a seatpost, or does it have to be bought or turned.
any other tips appreciated!
