This thread inspired me to have a crack at making something similar, so here's what i started knocking up over christmas, props to cantfindausername for a nice design
Base was tacked then tig'd (i'm still a learner) -
Cross beam to hold the clamp swivels -
Clamp is not quite finished yet, need to find my 20mm hole saw
Based on the clamp by 'park tools' -
Some 16g sheet, 3mm plate, small bits of angle for jaws and a couple of bolts... will post more pics when finished!
Need a bit more 20mm box to make the upright strut (which is removable from the base) and then hopefully get a chance to powdercoat it myself via a friend of a friend who has the free use of facilities at a college, i'm very excited about this part
