I have finally got round to designing and orderign the parts from my Jig. I have gone for the Rouke Cycles window frame jig.

So that basically a big 50mm box section frame with sliding plats with the attachements to hold the frame.

I have gone for stainless steel cones to hold the head tube and seat tube. 12mm rod machines to hold the rear axle and a m20 bolt and spacers fro the Bottom bracket. Pics to follow.

Some major fettling needed to get thsi 100% squared away.

Pics to follow.
