Stripped guide tube screws

[Dixie]

Any thoughts on the best way to remove stripped guide-tube screws? See this thread for details.)

[Zeke]

Are they frozen or spinning? Spinning to me is "stripped." If that's the case, I'd grab the tube with something that would put a good pull on it and then remove the screws a little on one side then the other. Frozen would call for heat and an impact screwdriver. Or is it the heads of the screws, you don't say. That, too, would be solved with an impact driver, the kind linked to on the other thread.

I'd heli-coil the holes once you get them out.

They're frozen. And there's not much left for the screw driver bit to engage...

drill until the head pops off, or a hammer and a sharp punch to dig in on the edge and tap in the loosening direction.

A manual, hit-it-with-a-hammer impact screwdriver works magic on phillips screws. I used to have a Honda 450 back in my pre-family days, and without an impact most screws (and almost everything used screws) were impossible to remove. Even works when the recess has been buggered up quite a bit.

Should there be any threadlocker in the guide tube bolts? I was thinking the low/medium strength may be recommended.

Heat them (pretty hot) with a torch. Make a simple shield (a piece of metal with a hole in it) to avoid overheating the surrounding case. After they cool remove them with an impact driver; the kind you whack with a hammer, not an impact gun. These, by the way, work best with a measured blow from a heavy hammer rather than a harder hit with a light one.

I need to clarify, I have mine guide tube and and wondered if it is suggested to use some sort of threadlocker on reinstallation. I used JW's method and just drilled the old bolts till they weakened. One thing I noticed was that once they got pretty thin you could put the drill on reverse and they'd back out very easily.
Thanks
