Post subject:  Grinding a butt stock pad/plate

I acquired a used shotgun yesterday that was fitted with a Jones Stock Adjuster mounting system and KICK-EEZ butt pad. As you can see in this photo, whoever installed it didn't do any of the necessary grinding to properly fit it to the stock:

I've never done any grinding of stock pads or plates myself, but I called the company (Recoil-Less) and spoke to a very nice older gentleman who gave me a couple pointers. His recommendation was to use a belt sander (which I don't have) on both the adjuster plate and the pad. He said I could also use a bandsaw (don't have one of those, either). The plate is 6061-T6 aluminum, by the way.

I might run out and buy a belt sander to do this project (unless someone wants to loan me one! :bigsmile: ). My question to those of you who have done this is, any tips on how to do this without screwing it up royally? I know not to do it with the plate & pad installed on the gun (duh), but then where do I do it? In a bench vise? And what grit do you recommend on the sanding belts? Is 50-grit too aggressive to start with?

Any tips are appreciated. :cheers2:

I have done dozens of them

Use the belt sander as advised, put tape on the wood and go slowly, keep all angles straight

like this

Thats exactly how you do it. How else would you match the angles of the stock without purchasing a fancy jig? Wrap a few layers of painters tape around the stock and use a stationary belt sander to take down the butt pad. I get about half way through a layer of tape and call it good.

Look back at the pic...there are 2 metal plates. The one attacjed to the wood is already perfectly fitted. The one attached to the pad is the one I need to grind.

My plan was to trace where I need to grind down to on the pad plate, then remove it and clamp it in the vise, take off the bulk of the excess, then check fitment periodically until I get it right.

You can use my belt sander, but I'm not sure I have the grit you want.

The manufacturer instructed me not to do it on the gun because the pad plate can move (its adjustable) under grinding force, and he said there's a higher risk of an errant grind on either the plate or the wood stock if I do it that way. Does that make sense?

Yep, that makes sense. Didn't know the pad would move while you tried to grind.

Use cutting wax while sanding aluminum to prevent the belt or sanding pad from clogging. Not fluid or candle wax....cutting wax. Fastenal or Tacoma Screw will have some. Regular hardware stores won't carry it.

Some rubbers sand best when frozen. Work your way down till your close then freeze the pad and do the finish sanding while it’s frozen. This is especially true with very soft rubber. You may have to freeze it for all of the sanding if it’s very soft.

I had to shorten the stock on my wife’s custom Ruger 10/22. The pad didn’t fit any more. I had to freeze the rubber to have it less grippy and sandable.

We never got to see the pictures of the process and outcome (well I did :bigsmile: )

Here's how it turned out:

The belt sander definitely made short work of bulk material removal (thanks a lot, Jim!). I opted to scrap the Jones adjustable stock system altogether because it had been completely bubba'd by the previous owner, and I really didn't care for it anyway.

As you can see, I didn't get the pad sanded perfectly flush, but that's because I couldn't get that kind of precision with a belt sander without running the risk of taking off too much. I sanded a little by hand afterward, but honestly I was in a rush at the time so I'll have to get back to finishing it later. It's definitely "good enough" for now, though.

The damage you see on the stock was already there when I started, although I did accidentally go through the tape in another spot on the other side (not pictured). I'm not losing any sleep over it, though - this gun will be a workhorse for upland birds, starting Oct. 5. :thumbsup2:
