Trying to get my 32 frame of unknown origon, model a front, banjo rear, extended rpu body to line up. How perfect does perfect need to be? I know the 'shops' have jigs....I have strings and tape measures. I think I am more like back then......but the HAMB beats up nothing less then wonderfull. I have built in adjustment in my build, it just seems HAMB rock stars are always right on the money.
