Peep sight blanks

[B.Habermehl]

I found this in McMaster Carr web catalog. I ordered one along with some left handed drill bits. Part # 3798K55 $10.87. Alloy steel. The hole is 3/16 ID. So it would make a Ghost ring for close work. The threads need extended with a die stock, and it generally needs a bit of a Diet. But it makes a good off the shelf starting point. It may be a helpful shooting aid for those like me whose eyes are going south. BJH

My wife found one of these on the bathroom floor recently and we can't figure out how it got there or where it came from.
I have never used them for anything in the house or shop.

You can get a similar, but trimmer sight from Skinner Sights in Montana.

The one Brenda found was a 1/4 x 20 and we do NOT have a cat but do have a miniature Dachshund.

Hmmm - Taylor's cats and dogs have only ever brought dust into the house.

What's the thread on the McMaster-Carr sight?

IF they are available with an unthreaded shank either of .160 or .187 it could be threaded to a 40 thread per inch and have a
.025 movement per full turn like a micrometer.As it is now it is a thumb screw and nothing else.

Why does the .025" thread matter? Different sight radius' are going to make each rifle's adjustments individual anyway - or am I missing something?

[Bob Roller]

Just my idea because of the association of .025 with precision measurement and  wanting a sight that doesn't look like a bolt.
I thought sight radius was determined by the length of the barrel and the distance between the front and rear sights.
It also comes from my ability to make a better looking sight whenever I need one.

Many of the original aperture sights of the 1800's had 80 inch pitch threads
just like on this close copy of an original pistol grip Hawken.(die and tap courtesy of Mr. Robert Roller)
