Picture of New Handle for a Broken Irwin Squeeze Clamp
I went to use this clamp recently. Either the plastic was brittle, or I squeezed the handle too hard. The part of the handle that adds pressure to the clamp broke in my hand. I decided not to discard the clamp and get a new one, but to make a new squeeze handle and continue using the clamp. The photo shows the break. 

Step 1: Tools and materials

Picture of Tools and materials
  • Hacksaw
  • Angle grinder with a cutting wheel
  • Grinder
  • Spring clamps
  • 1/8 x 3/4 inch strap iron
  • 7/16 inch rod
The photo shows part of the broken handle that will be used for a pattern. In my hand I am holding a piece of 7/16 inch steel rod I have ground away to copy the half-round portion on the broken handle. After grinding, I used a hacksaw to saw two cross section slices from the rod. It was necessary to cut a triangle to be welded to the 1/8 x 3/4 inch strap iron. 

you're the only person I've found whose seen the inside of an Irwin Quick Grip. Do you think the QG and its strength could be replicated well in wood?

You could probably make a demonstration model from wood. I really doubt a replica from would could have the same strength as the original from steel parts.

Thank you for the information. My fix for this broken tool may also help someone with a similar problem, but no warranty get their tool working again. And, it gave me an excuse to use my welder.

Indeed it is - Irwin clamps are a bit too pricey for me so this is a likely scenario for my cheap Chinese knock-offs - well done. Also I am pleased to see that the quality of your welds aren't all that much better than my own ha ha :-(

Jacquie Kennedy said she painted in a manner one's own family could appreciate. I have told people that describes my welding. These welds were worse than usual and inspired me to think about a guide to guide the gun, which resulted in my newer Instructable on Never Again Weld A Crooked Bead. (Never mind the comment below that was removed. It was what you see here, but I deleted it in order to clean up some typos.)

I'm like you that I make things that are a solution to a problem. I keep a stock of 1/4" round stock and have steel coffee cans full of bits of steel scrap.When the bits are 1" square or smaller they go into the recycle bin.
I think that the warranty policy of Irwin Tools is magnificent, but your repair is better than the original plastic handle, Bill.

I always like improving on things, and sometimes have dismantled new items so I could modify something I thought poorly designed or poorly made. Afterward, the item felt more like it was mine, and I enjoyed using it more because I knew it was better after I modified it.

You always surprise me, Phil! Another person had thrown away an excellent tool that could be recovered.
Phil B (author)  rimar20002 years ago
Thank you, Osvaldo.
Thanks for the share! I have a nice glue gun with a cracked plastic....maybe i can just fabricate new trigger. Thanks for the idea :)
