Increased capacity for homemade Claw Camps

**thehomeengineer** · Jul 12, 2024, 04:53 PM

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

) 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.

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

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

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.
