Periscopic Prism Sight Repair

[Terrylee]

Thanks, Chaps! The information supplied is most informative. I'd also appreciate some procedures with "do's and don'ts" concerning stripping the sight. I'm not into working on telescopic sights and would like to avoid the possibility of making any unnecessary error. I'd be grateful, too, if somebody could give me the address of a source of the appropriate wire. This would probably involve an overseas order for me.

Here's a picture of an original untouched (not by me anyway) PPco graticule from one of my other complete scopes, this will give you I hope a good indication of how thick the crosswire appears compared to say a No 32. I think most people will agree they would want to have the cross wire replaced with like thickness or as near as dammit for originality.

If I had to give you some do's and don't advice Terry, it'd be this. If you ain't done it before, then DON'T do it yourself. You can easily go beyond the point of no return. You've got to be VERY careful soldering the cross wire because if the diaphragm plate gets just a nadger too hot (that's another of these peculiar British Army engineering/technical phrases), then the actual grat post solder melts too..... and then...................

You have to stretch the cross wire too so that when it cools, it doesn't sag like your mum's washing line. If I was you, I'd get a cheap No32 or 42 to play with first. Don't want to put you off but........................

Simon,

Please do a photo essay, when you guys are gone we are all screwed.
The hands on nuts and bolts of all this stuff is lost in 1 generation.
The M1 Garand is one of the best documented rifles at the Govt level, but there is a lot missing and a lot of speculation.

Thanks

Gents,

If you bear with me I'll do one for the PP Co, Aldis and Model 1918. Will try and get started this weekend.

Cheers,
Simon.

After Peter's question regarding the availability of .0001 wire in the UK I thought I'd check on the latest prices with the folks I got my last lot from

Platinum wire .0001 is currently approx £190 Excluding Vat per two feet.
Silver wire .0001 is currently approx £95 Excluding Vat per two feet.

Cheers,
Simon.

Mmmmmmmmm, very thought provoking there Simon! And remember that if you make a cock-up (that's another typically English phrase for a mistake ...., albeit an expensive one in this case...) then you've got to do it again ....., and in some cases, again!

Things that can and do go wrong are it not being exactly square but only visible when it's back together! Goes slack after its cooled, visible twist in the wire and so on

B. Sullivan has repaired "a few" scope crosshair assemblies for me and other folks using no heat methods to attach the filaments. I know of several that have held up to many rounds and years since repair w/o problems, but I still figure solder and platinum will last longer (past my time, I reckon).
He can also delaminate and reglue lenses!

Peter,

I overcame that little problem by getting my hands on some solder of different melting points.

If you need some low melting point solder let me know and I'll pop some in the post.

Cheers,
Simon.
