I finally got around to testing and tweaking the collar wrench substitute I found.
I saw pictures of the spindle nut wrench and thought it looked like it might fit, or at least fit with little work. And sure enough:
The tabs on the wrench didn't fit right out of the box, but they were only 2/100" too big, so a bit of work with a file made for a nice tight fit:
As you can see, I beveled the corners of the tabs on the wrench for a better fit at the "bottom" of the slots in the collar. I could have hit the 45° better - oh well ...
A few notes:
- make sure to order part #3246. There are other, cheaper, wrenches that look similar, but are the wrong size. I know, 'cause I bought one
- the wrench is made of surprisingly soft material, so be careful with the file and measure often.
- I had to file down the little "hills" between the tabs to allow the tabs to bottom out in the collar slots:
- the wrench is fine for the home "shop", but not something you'd want to bring in your "save-a-dive-kit" - much too big and heavy.
