These clamps are Based on Starrett No 160 tool makers clamps whilst I wouldn't call these clamps tool makers quality due to the constraints of home workshop construction they will be more than adequate for most home workshop. I made them as a perfect matching pair to enhance there usefulness.
There has been a number of discussions on the forum regarding these clamps with a lot of interest shown in them, the original Starrett clamps can be picked up on flebay they go for about £30 to £50 pounds and Starrett still sell them for around the same price.
Any way this is my attempt
And to show them as to one of their uses.
They are made from standard size mild steel bar Body 1"*5/8" jaw 5/8" Sq bolt M8. Starrett fixed the jaw with a cerclip but I've used a M3 keep screw.

Thanks for your comments and interest chaps
They wern't that dificult to make.
To make the bodies a matching pair I simply bolted them together and machined them as one. I was unsure just how much the cold rolled bar would distort due to releasing the stresses:- so I roughed them out first and let them stand for a couple of days then I skimmed the base and top flat this took out the distortion.
Finishing off body
The jaws couidn't have been easier you just have to drill the M3 hole for the keep first before drilling 6.5 using the self centerng four jaw chuck
I used a M8 coach bolt to fabricate the screw and welded the knurled head in place.
Total material cost about £6 and not much more than a days job
