On my BM 910 the screw of blade axis is wringing out with ease.
I want to fix it some way, but I want to keep it adjustable.

So, I am going to try a drop of epoxy without the hardener on the threading.
Am I right or wrong?
 
Hey men! You are living in a great country, where loctite can be bought in every shop.

It's a shame, but I have never seen loctite here. Even in automotive stores.
 
It's really shouldn't loosen up that easily, but loctite will solve all problems. It's a blue liquid thread locker, commonly available at hobby shops.
 
If you can find a medium strength thread locker, that should be an equivalent. If not, a wrap or two of teflon tape around the screw will also work. If you have some liquid nail polish lying around you can also try a small dab of that, I'd try it on some thing cheap first just to make sure it doesn't glue the pivot permanently.
 
If you use what you are proposing to use here it will be permanent and you will never be able to get into it again.

Goop works fine, or you can use some tacky wax but I would not recommend epoxy of any kind.

Ok. I'll keep my eyes opened in the shops for any thread locker.
It seems that it will be easier found in the automotive stores.

But I did not found out from posts here, why the epoxy WITHOUT HARDENER is wrong solution? I have a bottle of epoxy for a few years, and it is still adhesive like honey or some kind of resin after the first inaccurate using.

I think that using epoxy without the hardener would make quite a mess. Over time, it would probably work its way out of the threads and attract dirt and pocket lint. It may even work its way into the pivot and bind up the knife.

Thread locker of some sort would still be your best bet.

Epoxy without hardener may eventually harden anyway. I have had it happen in my shop.
 
Hardener makes it harder, it still hardens without it, not as strong, but on threads it doesn't take much. And heating it is out of the question so you would have to drill it out.
 
Good to hear. I had forgotten about the permatx brand name, we have it here too. It's pretty much identical to loctite, I think the two brands are under the same company.
