Just a couple quick projects today that I've been meaning to finish.
Added a set of Uncle Mike's sling swivels to the Benjamin Sterling HR-81. No pics of the install. Just had to drill a hole. (Of course, there was a bit more to it than than, but only due to my agonizing about getting the hole properly centered.)
Used kit #1071-2. The cocking lever measured 0.432" in diameter.
Found that the supplied 3/32" allen wrench in the Uncle Mike's kit was a bit undersized. Threw it away and found one in the tool box that fit substantially better. Helpful tip installing the band: Get the hollow, flat head screw where you want it first, then snug down the upper allen head screw to lock it in place. If the band rotates slightly when you load the sling (some barrels are hard to get a grip on due to high polish), sandwich a small piece of 320 to 350 grit emery paper between the barrel and clamp. Put the abrasive side facing outward against the clamp. Cut the emery paper just smaller than the clamp so it's completely invisible.
Also wanted a better sight on the Sterling ever since I saw Precision Airgun owner, Chuck's, personal HR-83 wearing an Anschutz diopter. It made my Beeman (Williams made) target sight seem somehow, you know, inadequate. Even with the old, adjustable Merit aperture, it wasn't quite what I envisioned. Attempting to do this without spending any money, I scrounged around the parts bin, and came up with the recently removed diopter from the Tech Force TF-79.
This particular sight made the cut because it would clear the radius on the top of the Sterling. The only problem was the dovetails on the sight body were too narrow by just a few thousandths.
Set it up in the milling machine.
Barely kissed each side with a 60 degree cutter.
Was a very snug fit--almost needed to tap it on. Probably still fits the TF-79.
Project dos:
The other project was making a jam nut for the chopped down IZH 61 rifle. Wanted to try a standard M-16A2 rifle flash hider, but when tightened down, the slots didn't center up.
No pics of the process, it was simply a matter of drilling a piece of steel, milling two wrench flats and threading it. OK, actually did have to make the 1/2"-28 tap from a piece of tool steel...
Jam nut screws on first, followed by the flash hider. Align the flash hider then tighten it against the jam nut. Done.
More soon.
