converting frames to take disc brakes

[B3]

B3 how did you set up the positioning? Nice job BTW

I made a jig from 30mm thick aluminium that bolted to the dropout.

The discs on my AMP bolt to the dropout, which has no bracing as it's a horst pivot, using 2 M5 bolts, with a 140 disc on the rear i've had no problems with it. But then everything on the AMP is ultra small & light

Good clean job, you got the skills B!
