Title: Anyone ever 'widened' a slot in a chock? Post by: wnethercote on February 20, 2012, 06:32:35 PM I started off with Hamel chocks (well actually, after my first steel ones), which tended to be a bit 'wide' so I often built my runner bodies towards max tolerance on thickness. Some years ago I bought a set of German chocks from Northwind, which were tighter, but still wide enough for my fat runner bodies to fit. Most recently I bought my first Struble Chocks, and they are either under or over the nominal inch by just 1/128 ... and some of my runners no longer fit.
I could throw the offending runner bodies on my belt sander, or even build some new ones, but has anyone ever milled the slot wider on a set of chocks? I am inclined to say that it would be a bad idea, since the stress risers at the bottom of the cut might lead to cracking of the chock. Thoughts? Title: Re: Anyone ever 'widened' a slot in a chock?

I'm not sure how large a radius you can tolerate; if it's too small then the required diameter bit might not be stiff enough.

You need a goo machinist but can be done Title: Re: Anyone ever 'widened' a slot in a chock? Post by: wnethercote on February 21, 2012, 09:56:23 AM Thank you both. It sounds like an off-season project!
