Machine Shop / Fabricator for a frame help!

Hello all,

Ive come to a point in my project where I need some help with fabricating a lower frame for a swing arm swap on my Yamaha TR1. Ive attached a render of a CAD ive made of what im after (battery box on the bottom) made in stainless I reckon. Its roughly 320mm x 160mm x 180mm.

I bought myself a 200amp TIG welder last year but I don't think ive enough experience as its structural I wouldn't know if my welds are good enough.

Can anyone suggest someone that can help as im at a bit of a dead end. Can certainly go into more detail. Would also like to hear some opinions.

Thanks everyone.

Well the material will be spendy, and it would probably be worth looking into somewhere with a waterjet to cut all the pieces out. A few years ago metalsupermarket charged $60/hr for waterjet. That would by far be the least expensive route to go. As for welding you'll probably need to look up fab shops in your area and make a dimensioned blue print for them to work from.

Thanks for the reply! yes I did think that could be the way to go, I could tack it all together and get someone to finish it off. Think I could just make it from mild steel? The new swing arm as bearing pressed in so maybe don't need the axle to be solid through, maybe a pipe with pressed in top hats?
