Default C-661 Slide block

Question: drilled and counterbore the slide block to accept the Clovis pin. So far so good. Now Iím getting ready to drill the hole for the cotter pin but Iím having some trouble getting a mental picture to how this is supposed to work. By my estimation the cotter pin will not be long enough to span the UHMW block to be able to crimp it over on the back side. Is the pin meant to be press fit? Thanks in advance.

Yes, that's the way I understood it. I decided to thread the block and replace the cotter pin with a long thin screw - I believe it was a 2-56 or something like that.

Would it be possible to get a long cotter pin so it would stick through the UHMW block and get bent over?

Why is it that the simplest solutions are the least obvious. Thanks again.

Default Bolt and castle nut

On the 7 slider the bolt goes all the way through with a nyloc. I used a drilled bolt with a castle nut and cotter pin.

I cannot be, nor will I be, held responsible if you try to do the same things I do and it does not work and/or causes you loss, injury, or even death in the process.
