I'm at about $4000 now. Bringheli jig, used vert. mill, shipping to get mill to the shop, files, grinders, Anvil Chainstay fixture (not a necessity, but makes life so much easier, well worth the $700), auto darkening welding mask (again, not really necessary, but auto darkening is worth the coin), hole saws, misc items, TIG rod (10lb min of $18/lb tig rod is an expensive purchase)

but.... my friend is letting me use his shop space, OA rig, Tig welder, compressor... so tack on about $5000 on top of that if I were to do it alone
