cross hair wire

Hello guys
I have an old Unertl 10x scope sitting on a custom Saturn 220 swift that was my fathers. Problem is the vertical cross hair is broken. I am having zero luck finding anyplace or person willing to sell me a foot or two or any length for that matter. I understand it should be .0005" or thinner diameter.
I have removed the broken hair. It does take a very very small screwdriver and pointed tweezers. It can be done. Parsons wants $100 plus shipping. I just can't justify that money for winding a wire around a screw. It may take 2feet worth to get it right but I thnk I can do it. (you don't actually wind it around) more like lay it beside the screw.
Anybody know where I can get some to try?

I tried my cat's hair at .00025 but it breaks way to easy. The cat is one of those Persian type cats with long thin hair.

Just a thought

You might music wire,sold at piano stores less then 20 bucks take your mic or down load a chart online. Good luck..

McMaster Carr. Measure the wire to be certain of the size.

Piano wire goes down to .001 per the chart. About twice as thick as I need. McMaster Carr-could only find wire down to .004 thick.
I found a magnet supply outfit that is sending me a sample of #54 wire which is .00063. A little to thick but I'll try it. It's copper with insullation. I'll have to strip the insulation with something.

Have you considered the windings from a set of walkman type earphones? That should be really fine wire. The smallest I have is .003 (0.089mm) tungsten wire.

Just came to mind, the nylon filament from pantyhose should be very small in diameter.

I'm in the same boat. Needing to replace the reticle in a Unertl.

Found this source for wire while researching. Don't know if it would work.

I'd be happy to share the sample wire if it works out ky. The link you provided will not be fine enough I'm afraid at least for my 10x. like I said I tried my cat hair and looking through the eye piece(although broken) it was the right thickness at .0005 or less. .001" will be too thick for my liking.

I wouldn't what to do with spider silk! You?

I replaced the wires in a scope many years ago I started cutting into old electric cords and finally got to a piece of welding lead, (hundreds of fine wires) and used that copper wire. Used that scope for years after that with no problems till the rifle was stolen.

From my post above. Looks like the guy is selling it on eBay right now. I just bought 10 ft. .0005 tungsten.

Just a thought... I needed something pretty much the equivlant of spider silk for a photo project. I ended up taking a plastic/nylon comb and hitting it with a heat gun until the melting point and pulled on it as if you were stretching it out... hope that makes sense. I ended up with "threads" to the point of being so thin they became almost invisible. Like I said, just a thought.

American Scientific has tungsten light bulb wire stock down to .002 and is super strong stuff. Sad thing is you have to hunt and search for things at the American Scientific web site as they have no real organization of products and changes daily. The web site is http://www.sciplus.com/

I used the tungsten wire to repair a 1920's savage scope and has worked out perfect.

I would suggest you call them and ask the cust service lady that answers, they seem to know what is there by heart.

There are also many other items in that place that would be gun smith or gun project friendly.

No I haven't received it yet. I expect it tomorrow or Monday. He was really quick getting it out. I'll let you know how it goes.

Got the wire in today. After about 4 hours of hell I finally got it re strung. It turned out perfect. Identical to original I would say.

Come on warm weather.

Received my .0006 copper wire Friday. 3 hours of hell then I put in my order for tungsten. Copper is way to soft. Tighten the screw down and it pinches off the wire. BTW I broke the good hair while messing with the other one.
Good to hear it works well.
Nice looking rifle.

Copper wire doesn't work. it's too soft.
Received my .0005 tungsten last week or so.
Going blind trying to get it installed.
KYSilverado--did you have any secrets your willing to share. 4 hours of hell you had to learn something.
I borrowed more magnification today. Maybe that will help. Boy is this stuff small.
Correction. My first post said the rifle was my fathers. As I re read that post it sounded awful so I must make a correction. The rifle is still my fathers. I borrowed it for a little target shooting. My dad is here and doing just great at nearing 80 years old. Thanks

I just made my first attempt at replacing reticle wire. Pretty sad but not so bad that I will not try again. Im just messing around with some old 4x Weavers and even with those the finest wire i can find (From the voice coil of a small speaker) looks about twice as fat as it should. Also i ended up with rather cold joints due to trying to use an iron without enough watts to heat the frame properly. I knew it wasnt going to look right but reassembled the scope--I had a good laugh when i looked through it. I think ill get so better wire and try it with the brass frame preheated.

I was putting it mildly. Believe it or not I did it with little to no magnification. I did have a small magnifying glass with a light. No tweezers. Just scotch tape, black construction paper and the screwdriver.

I gave up trying to work off the spool with the single strand. I all the wire on the spool one time leaving several threads dangling off the spool. Put them on the paper and under bright light. I could see them fairly well then. Find the end of one and get scotch tape on it. Pull it over and tape it to the reticle tube under a screw. Stretch it gently across to the two screws with the thumb of your free hand. Screwdriver in the other. Screw in one screw. Keep a enough pressure to keep it tight and tighten the other. Cut the ends.

Got it.
I used mucho magnification, lots of bright light, pointed tweezers & and very small screw driver. With all the above I did it in less than 1/2 hr.
Glad that's done.
