Ugly Nubbins

[Russ]

I got my SuperBolt (WooHoo! ) in today along with a package of plastic nubbins. It's sad the way the "nub" on the backside of each nubbin is just (hack!) ground down on a belt sander! There is quite a bit of variation between nubbins as to how much material is actually removed. Some are ground very crooked as well.

Tom, I hope you modify the cavities in the mold, in due time. (Weld 'em up, and re-EDM them to have a nice, consistent flat)

Tom, I have to agree that the nubbin is fine until you see the back side where the nub is extremely poor (uneven and irregular from the others but they all stick up beyond the barrel's crevice) and exactly as explained. So bad that when I put my barrel in to my gun it was jammed and took an extrme amount of effort to get it out. I took the liberty of just hand sanding mine down. I have not trid them again since but I would definatly take another look at the production runs tolerances.

A Moldmaker? Yes I am.

I'd rather see them not "customized" at all, because they still had to be trimmed to fit my individual barrels.

kilaueakid, at least they're not belt sanding the bolt faces! :)
