leaf sights
#151275 - 21/01/10 01:25 AM

While working on a rare old 404 by Schuler (manuf. 1923) I found one of the two rear leaf sights missing. The rifle has a fixed rear sight, a folding leaf ahead (300 yd), and a folding leaf (200 yd)behind the fixed rear sight which was missing. When I fabricated the sight i found that there was no mechanism to hold it in place, also the exisitng 300 yd leaf did not stay put when flipped up. What is the standard mechanism to hold flip up leaf sights in place?? could the experts help??
Regards

Most of the ones I have seen or worked on had a hollowed out base with a flat spring inside to bear up on the bottom ot the sight leaf. The base of the folding leaf will be somewhat triangular and the corners on the triangle either hold it up or down when it is folded. I know this sounds complicated but it really isn't, I may not have explained it very well. Bob H.

As Bob says they usually have a spring system, of varying designs, to hold them in both the raised or lowered positions.
Some however, rely on nothing more than friction to hold them in position. These use a simple hinge design, and are originally set up with a friction fit on their hinge pin.
They do sometimes lose the friction due to wear, and will flop up or down whenever they want to, usually at the most inoppertune times!

I had one that was flopping around as described. It was the type of rear sight with a standing leaf flanked by a folding leaf behind and a folding leaf in front. The front leaf was loose.

I drifted the sight assembly out of the rib and found that each folding leaf had a small leaf spring bearing against the sight leaf. When upright, the leaf spring lodged in a flat on the bottom of the hinge part of the sight leaf, thus holding it upright. The little leaf spring for the front sight leaf was broken.

I fabricated a new leaf spring using a binder clip for material. I cut the leaf spring out using a cutoff wheel on a Dremel tool, then smoothed the edges with stones. It now works perfectly. Easy fix.

This goes in the same slot as your ledger paper 'pinstripe bullet jacket' maneuver.
Good on ya!

Do you mean this one?

DAPPER EDWARDIAN GENTLEMEN IN PINSTRIPE SUITS:

A week or so ago I searched the stock room of my office for papers suitable for making paper patches. I hit paydirt with two boxes of paper designed for legal transcripts. It has ruled margins with two vertical black lines on the left margin and one vertical black line on the right margin. Laying out my patches just right gives me this "pinstripe" effect, which I think is pretty cool.

As a bonus, this is really great paper. Heavy 100% cotton. It measures .0032" thick and makes a really great patch.

I just noticed you can see these bullets with the patches on but yet to be loaded in an earlier post on this thread just above.

After all, an Edwardian gent should wear his pinstripes to look his best.

What a memory you have!

Tinker was remembering this from almost two years ago. It was a post I put up on This thread.

It was when I was just beginning to load for my .577BPE Henry.

Clever Tinker!

Curl is correct.
I don't tend to forget much.

The part I find so entertaining is that these particular elements of feeding and maintenance of Victorian double rifles are daily bench-gravel for a Barrister, not a gunmaker!!

How appropriate

As we can see here, this community brings out the best of all of us, bits and parts from all of us - from all walks of life -- to better the collective school of thought.

Way to go Curl!
