Increased capacity for homemade Claw Camps

Hi All
I was very lucky to find a Bosch extrusion frame during a skip dive. Ask if I could repurpose the frame and was told just take it. (Didn’t need to be told twice :lol:) I knew straight away what I was going to do with the aluminium and fittings. Increase the clamping capacity of my homemade claw clamps. The frame was stripped down to component parts, and some of the extrusion cut to the required lengths needed. Some drilling of the extrusion and modification to some standard M6 Bosch tee nuts to suit the claw clamps and we were in business.

The photos below show the blocks and fittings and the blocks being used.

Attachment 47669Base block: 50x50mm extrusion drilled to accept a homemade standard tee nut (drilled and tapped M8) to fit machine tables.

Attachment 47678 Block bolted to drill table ready to accept claw clamp.

Attachment 47670 Attachment 47671 Attachment 47672 Modified Bosch M6 tee nut to M12 stud to fit claw clamp.

Attachment 47673 Modified tee nut in place.

Attachment 47674 Attachment 47675 Claw clamp raised 50mm.

Attachment 47677 Additional extrusion can be clamped together to increase height with standard Bosch fittings and
drilling extrusion to accept the fittings.

Attachment 47679 Attachment 47680 Attachment 47681 Clamp system to join extrusion.

Attachment 47682 Increased by clamping three blocks together to 150mm.

I also have some double extrusion 50x100 which has been modified. So the height is limitless.

It's good stuff that extrusion, I've been making things from it for 30+ years for my employers, both directly and designing for off-site assemblers to build, and from off-cuts that were being binned for myself. One of my fellow engineers used a scrap length of the 4" x 4" to suspend the engine and gear box at a low height so he could wheel the chassis of his frog eye sprite under it in his garage.
