Front wheels are no problem

The way I built the front wheel/cross boom assembly on the 20/20 and some of the others by welding the tab onto the brake/steering arm first , drilling the cross boom on a pillar drill then welding the steerer tubes on then the whole assembly can be welded together after chamfering the bottom of the fork tube and measuring the distance between the "jigged up tabs and the cross boom " at each end - took me about 2 hours for the complete cross boom from start to finish

the method is on one of my "many " builds
