Removing a stripped front asa thread on a cocker

Brick · 03-11-2009, 11:40 PM

So I've got a 2k2 vert body that I am doing some milling on and have run into a dilemma. The screw used to hold the vert ASA on the body is stripped (not my doing, a previous owner at some point). As far as I know, it is hardened steel and I know that it is REALLY torqued on there, any ideas on how to get'er out?

blow torch?

I had that problem and just sold the body instead of screwing with it.

:P tried the blowtorch, assuming it was loctited. No give.

find some masonry bits and drill out the majority of the bolt. masonry bits have carbide tips so be gentle to them, as they can crack VERY easily. go nice and slooooow and use lots of coolant.

^ Thought of that aswell, but when it's drilled out, where do I got from there? I want to make sure the ASa thread stay intact so that I can mill and re-attatch the ASA (without the stupid 12point hex bolt, damn that was such a horrible idea on WGP's part to continue with those)

There are machine shops that have some sort of electrical device that "zaps" them to get them out.

Its a tough one because you cant cut it easily for a slot. The asa also probably has shoulders on it so even if you cut the head off the bolt, you could not rotate it off the body.

Mmmm....maybe try putting it in the freezer overnight. The metal will shrink and you might be able to get it out in the morning.

my buddy somehow got in their with a dremel with a cut off wheel and slotted his because he didnt have a 12 pnt socket to get it out. Im assuming its the 12 pnt socket style and not an allen head.

Rick you are thinking of an EDM machine. extremely slow, but it can cut ANYTHING that condusts electricity.

Brick · 03-12-2009, 10:29 AM

I'll try the freezer thing, but I don't understand how that will work

There is no chance of being able to slot it with the tools I have. My smallest mill bit your just demolish it, and trying to use a dremel.. well.. i'd rather not.

use an ez-out

drill a small hole in the head...screw 'in' the reverse-threaded ez-out

The freezer trick is to cause the metals to shrink...if the metals are dissimilar(or a really different shape, as in this case) then they will shrink at a different rate. The different rates of shrinking will cause stresses at the interfaces. This can cause the crud/loctite at the interfaces to crack and loosen. This can be taken to the extreme by freezing overnight and then heating under hot water.
