I saw in the other thread where someone paid $45 for UHMW! Eeek!
[url]http://www.drillspot.com/products/446941/Approved_Vendor_1ZAV9_Sheet_Stock[/url] for 1/8
[url]http://www.drillspot.com/products/517355/approved_vendor_2nhv9_recycled_sheet_stock[/url] for 1/4
Now there is a reason for the 1/4 = I am bolting it down and the countersink head requires some depth.
I'm working on the second set of hook now and might cut the UHMW today or tomorrow and post a how too then. I did learn a little from the first set and the second set will be slightly different. Just some small changes.

I discovered the the GPR378 uprights are somewhat warped. The NYB had exactly 3" of clearance, and while they slipped on without a problem in some places, they generally didn't fit. It was weird. I'd have to slam them in place with the palm of my hand on one spot and practically need a hammer to get them off, but if I moved up three holes they would slip right on.

Yes Body solid punches the holes, so it distorts the metal. I used spacers on the jig to make the area just a hair bigger than 3". There are tight spots and slightly looser spots, but they just slide on.

[QUOTE=Andrew_WOT;994907603]Great, informative post.
Can you please post the source and item no of that UHMW as well as what kind of glue you used on them.[/QUOTE]
Sure, I provided more detail over in [url=http://forum.bodybuilding.com/showthread.php?t=150387033&p=994896083&viewfull=1#post994896083]BAVE's thread[/url] this morning. The SKU # of the UHMW was 517355, although I would have gone for a thinner version if I had to do it again.
Edit: Don posted links to the actual UHMW product a few posts above. If you want to screw it down, I'd go for the 1/4", but if you want to use adhesive tape, I'd probably pick 1/8". My sheet was slightly warped when I got it, so I had to spend a little effort trying to flatten the entire thing. You don't have to use heat--I found that bending the plastic in the opposite direction seemed to work even when cold.

Thanks buddy, very helpful.

Marking holes in the UHMW with a white paint pen because some dope got the holes slightly offset from center. It was cut with a saw the razor knife is for deburring the edges.

I will take off the plastic and give it a coat of black later.

Nice work Don....much better than the ones that come with it...yours' are more of a true powerlifting J hook.
I like your becuase you could probably keep in a better position when you unrack the bar.
