Locktite and barrel timing

[Wrangler100]

If you use over 100 ft lbs to get the barrel to time properly is there a need to use locktite? I can't see a need unless the barrel is not very tight. Comments?

no locktight is necessesary. what is important is to get the barrel to come to 1:00 o'clock,looking down the barrel, when tightened by hand. this gives you the proper amount of "crush" when you wrench it in. also make sure your receiver block fits correctly before you tighten the vise. i've never seen one work loose when installed this way.

Tommy, did you mean 12:00? http://www.fnfal.com/forums/wink.gif

Snakeshot, Tommy said it should time to 1:00 as viewed from the breech end when you HAND tighten the barrel. Going the rest of the way to 12:00 or TDC ought to be tight enough. Nope, you definitely shouldn't need any Locktite after you crunch it. As explained to me, what is happening is that you're stretching the threads and that's a pretty tight fit.

Loktite is not necessary if building for yourself. I've used it as a CYA measure ever since I got an izzy back where the customer had pulled the barrel, reinstalled improperly, then returned for "warrenty" work. Since red locktite must have heat to melt, its pretty obvious when its been messed with. For the same reason, I use obnoxious colored nail polish to coat the screws after doing trigger jobs on Rem and Win rifles, and you'll notice many auto service centers mark the bolts after changing lube - keeps customer from claiming the bols were loose and the fluid drained and ruined the gearbox/transmission, engine.
