LESchwartz 9 Posted May 1, 2012 Report Share Posted May 1, 2012 What's the best way to get the thread protector off an IZ-340? thanks, Larry Quote Link to post Share on other sites
Shandlanos 1,470 Posted May 1, 2012 Report Share Posted May 1, 2012 I haven't seen these yet, so I'm not sure how they're attached. Usually thread protectors are just tack welded - one little blob of steel "permanently" attaching the thread protector to the FSB. If this is the case, carefully cut or grind away the spot weld. Take your time with it. Remove material, clean, see how much material is left to remove, repeat - you want to remove the absolute minimum amount of steel possible. You'll want to refinish the little bit of bare metal left on the FSB. I usually use a little bit of cold blue to clean up after I do this on an AKM. Quote Link to post Share on other sites
jeepranch 16 Posted May 1, 2012 Report Share Posted May 1, 2012 I just cut one off last week, mine had 5 spot welds, I used a cutting tool on a dremel and carefully ground down the spot welds to match the contour of the fsb and shroud, when it didnt come loose I worked my way in to the shroud until it did. pulled it off, ground down the remaining bits and was good to go, shot it last weekend and couldnt be happier.

wtjosaas 72 Posted May 1, 2012 Report Share Posted May 1, 2012 Mine wasn't even welded. The back edge had a couple indents but it was able to spin around. I used a cut off wheel and trimmed the back edge enough til it slid off. Quote Link to post Share on other sites
LESchwartz 9 Posted June 9, 2012 Author Report Share Posted June 9, 2012 (edited) I removed the plunger and spun the rifle on my lathe: The plunger drops out the back of the FSB. Clamped the thread protector in the chuck and supported the rear trunnion in the tailstock (wrapped it with duct tape to protect it). I used a 3/32" cutoff blade to cut the rear or the thread protector loose, then finished with a dremel. Looks pretty darn good. Larry PS: Got the whole thing converted in about 6 hours, start to finish. Edited June 9, 2012 by LESchwartz Quote Link to post Share on other sites
LESchwartz 9 Posted June 16, 2012 Author Report Share Posted June 16, 2012 OK, I finally finished my project . . . as expected this was easy to convert and beautiful. Here are the photos: 1 Quote Link to post Share on other sites
