aerosigns Posted November 25, 2006 Share Posted November 25, 2006 I recently had my SDM Fiber Optic rod fall out. I now have plenty of replacement rod, but I am not sure how to secure the new rod in. The SDM sight has a front and rear post. The front has a small dimple for the rod to rest, and the rear has a pass through hole for the rod to extend. Do I use blue Loctite, superglue, finger nail polish? Thanks for the help. Link to comment Share on other sites More sharing options...
Rumpy Posted November 25, 2006 Share Posted November 25, 2006 Use a lighter to mushroom the ends ......... Link to comment Share on other sites More sharing options...
Tom Mainus Posted November 25, 2006 Share Posted November 25, 2006 The 25-2 I just got has an SDM sight on it and I was wondering the same thing. All of my other fibre optics the rod goes completely through the sight and you mushroom both ends with a lighter. The SDM sight the rod doesn't go through all the way in the front. What's up with that? Tom Link to comment Share on other sites More sharing options...
aerosigns Posted November 25, 2006 Author Share Posted November 25, 2006 This is why I think my FO fell out. I am thinking about heating it in the middle, and then using a small pair of pliers, squeeze in the middle so it won't come through the hole. or I am going to loctite the little sucker in there. I think SDM just puts a little red loctite on the solid front piece, and that is all that holds the FO in place. Everything else is very clean, no residue of any adhesive. If you want to try some other colors PM me with your address Tom. I got 3 ft. of each color, and need 1 inch. The violet you can't even see. The light blue is visible, but not subtle. I am installing that one for tomorrows match. The orange is bright and clear, but I might get back into trouble like I did before. The green is so bright it burns a hole in your retina. I know I would be in trouble with that one. Link to comment Share on other sites More sharing options...
CSEMARTIN Posted November 25, 2006 Share Posted November 25, 2006 I had the same problem. To fix it, I drilled a hole all the way through. Now I melt a mushroom at both ends- problem solved. I also think it is a little brighter. Link to comment Share on other sites More sharing options...
Bill Nesbitt Posted November 25, 2006 Share Posted November 25, 2006 I fasten my fiber optic rods with a small drop of super glue on the muzzle end. I don't think I ever lost one using superglue. I have lost rods that were melted on each end. Link to comment Share on other sites More sharing options...
aerosigns Posted November 25, 2006 Author Share Posted November 25, 2006 Thanks guys. Bill, I will try the superglue idea right now, before I go with CS' idea about drilling through. I did 'flame kiss' the end of the rod, which cleared and brightened it up dramatically. It's a good thing I have lots of this stuff, 'cuz it sucks trying to snap it, cut it, or anything else cleanly. The best I have found is to snap it with your fingers, then give it a little flame to clear it up. Thanks. Link to comment Share on other sites More sharing options...
Bill Nesbitt Posted November 25, 2006 Share Posted November 25, 2006 I prefer the end of the rod facing me to be slightly recessed. I cut the rod with sidecuts to slightly too long then rub the end on sandpaper to shorten to length. Smooth the end on emory paper for the final shine. I don't like a starburst on my sight. Just bright enough to see the sight better in poor light. I use the top of the sight for precision shots. Link to comment Share on other sites More sharing options...
newshooter Posted November 25, 2006 Share Posted November 25, 2006 I was wondering where you find these 3ft. peace's of FO rod. I am starting to run low on red and other colors which i have not tried cause i only have out 3 inches of yellow and green. I was trying to find some places that sale this stuff.

Jimini Posted November 26, 2006 Share Posted November 26, 2006 Thanks for the info on where to buy fiber optic. Use a lighter to mushroom the ends ......... that helps to keep you in line with the front sight. If you are not lined up properly, the sight is not completely visable. Mushrooming the front of the optic rod does not help secure the rod becausee it is the rear of the rod that gets the most "hammer" from the recoil. It is best to use some superglue to secure the rod to the sight. That way you don't have to mushroom the rear or sight end of the rod. You don't want a big blob staring at you, just a dot.

When super gluing a rod in does it leave a mess when you replace it? do you have to find a small enough drill bit just to clean out the hole for the new rod that you are going to put into it?? Also i was wondering when i super glue some stuff around the house some of it tends to turn white will this happen with the F/O rod also?? Thanks for the Websites for the F/O rod thats a deal compared to the local gun shop that wants 9 dollars for a 5 or 6 inch peace. Link to comment Share on other sites More sharing options...
señorballistico Posted December 10, 2006 Share Posted December 10, 2006 (edited) I lost the fiber optic out of a nearly new front sight while taking a class with Bruce Gray. I shot the rest of the day using the sight as is. After shooting had ended for the day, I trucked back to Bruce's house and he installed a new little piece of fiber optic "tube". He secured it with plain old Devcon two part epoxy. I was skeptical at first, but it works great. That's my new attachment method for all my FO front sights.

kurtm Posted December 10, 2006 Share Posted December 10, 2006 Super glue!! I did get a drill bit the same size as the rod, but since it was SGed into place I haven't had to replace it. I like the SG option as I don't have to "mushroom" the ends and can run a much smaller, more precise, fiber rod! KURTM Link to comment Share on other sites More sharing options...
slavex Posted August 30, 2007 Share Posted August 30, 2007 diggin up old threads. I think I am going to get some superglue tomorrow as the mushroomed ends are no where near as bright as the plain old cut ends. so when using the superglue method do you guys put a little in the hole at the front of the sight, then push the rod through, or put the rod in the hole, almost lined up, then some glue on the rod and push it in the rest of the way, from the muzzle?

Jaxshooter Posted August 30, 2007 Share Posted August 30, 2007 I put a small dot of superglue in the dimple in the front and mushroom the rear. The superglue dosen't make any mess unless you get carried away. If you don't get the FO to hot it will stay bright when you heat it. Link to comment Share on other sites More sharing options...
slavex Posted August 31, 2007 Share Posted August 31, 2007 my probelm seems to be overheating the FO, it loses it's brightness. Superglue will be tried I guess. Link to comment Share on other sites More sharing options...
