Hook wrench

I use this articulated pin spanner for my 5C collet blocks - works just fine.

It's part of my pin spanner collection...

These are available from most machine supply houses including McMaster-Carr - both fixed and adjustable varieties.

Thanks for showing those. I did see a style like yours in a tool supplier & also Amazon. I think they are a better principle & more universal size range. More moola of course.

I seem to recall the one I saw at ?KBC? had a pin diameter that didn't quite match what I required. I guess slightly smaller pin might be ok but larger would be non-starter. Maybe if a guy borrowed their hinge principle for a homebrew handle & made a set of threaded pins in diameter gradations. Project # 172 on my list LOL
 
I am taking this wrench making idea to the next level. I have made a few different sizes to fit my different collet chucks.

@Alexander please tell us more about those machined tabs and how you did that. Fusion? Then what? Hack saw? how thick are the tabs? How strong are they during the milling?

Fusion actually has a really good tab option. I usually put just 4 tabs on a part this size. Make them .2" wide and .04 or .05 thick. These tabs are only .02 thick. When the part is done I just tap it with a hammer and it will fall out. I finished the edges with a belt sander. The material is aluminum because that is what i was able to salvage from the scrap bin. Some steel would have been nice but I didn't have enough.
