Odd, isn't it? Someone in this thread said they had to make a 10 point tool another had a 4 point jobbie- the cart we had was a 6 point with a 33mm OD on the cart.
I've taken forks apart using the holes before- scares the crap out of me. Way too easy to make it out of round.
We made the 33mm aluminum vice jaws to clamp the cart and the proper (for what we had to work on) 6 point tool.

Ok, just check out the page on the site...
