I have a situation where I need to screw into some aluminum.
Can a helicoil be installed at the bottom of a deep hole, or even on the other side of a deep counterbore? Say I've got two parts:
\ ------ ----- \ |_ _| | \ | | | ------------ ------- ------------ ------- / Z Z | / Z Z | ------- ------- / And where the 'Z's are, is threads. It's aluminum, and it's made of one piece, to be a clamp that looks like a fat snap ring. (to the left, out of the picture, there's a large circle. I've hinted at it here.)
So I either need an installation tool that will go through the thru part to install the HC, or install it from the bottom, which would make it backwards to the screw.
Can a helicoil be installed from one side and take a screw from the other side? Especially one that doesn't need a terribly expensive insertion tool?
Of course, other ideas are welcome - I'm kinda thinking Keensert, but do they work backwards? I'd have to put more meat on the thread end, but that's not a problem - It only exists on paper so far. :-)
And I did a search (just in s.e.m and r.c.m), on "keensert" and there was a thread where somebody mentioned yet another kind of insert; if anyone wants to give me a pointer to them (if they fit the bill, of course) I'd appreciate it. :-) Since it's a new widget, I don't think I'll need Loctite thread goop quite yet. ;-)
