Screw Removal

Pappy K · Posted: Wed Aug 24, 2011 6:19 pm Post subject: Screw Removal

Well this is not a Tip or Trick; But, a request for someone to provide a Tip or Trick to solve this problem.

When I crashed my "Brand New Lama 3" last Saturday I managed to break off a screw that holds the arm on that controls movement of one of the blades.

Here is a picture of the problem:

The problem: How the heck can I get that screw out? It seems to have been put in with locktite or something similar coz I can't get it to budge. Any suggestions on how to break a locktite connection? I thought maybe heat; however, I'm a bit scared to apply heat a torch to it.

Hi Pappy,

Luckily you have a fair amount of screw protruding,

I suggest first you disassemble the main head, to gain access to this screw, you then have three options,

Use plies to unscrew, or cut a slot with a hacksaw using a screwdriver to undo, or if really tight in use a soldering iron, to soften the lock tight.

As a last resort re-drill and tap. Good luck.

By the way nice photo.

Trev.

I agree with Trev: it looks like you might be able to get in there with needle-nose pliers.

If not, I once used a Dremel to cut a slot into a screw and removed it with a flat-head screwdriver. I've also seen screw extractor drill bits, but I don't know if they come that small.

Good luck!

Hi Pappy,
i'm sure i read some where that thread lock can be undone by heating the affected part with a soldering iron.

Disassemble the head.
Use soldering iron for heat to loosen the locktight.
Visegrips and your home free.

Good luck with the repair.

Oops

I knew i read it somewhere Trev, it must have been in your post.

Many Thanks to All Exclamation

I was about to apply a mini torch to it and then I read your kind responces and applied my soldering iron to it. Presto, Out It Came Very Happy

I guess I was luck in one way that when it snapped it left me a stub end to work with.

Thanks again

I'm never that lucky. When they snap on my stuff it's always flush with what ever fitting the screw was in. I always have to drill them out and then use a tap hoping I have the right size..

It's a real pain because you must line every thing up. use a vise to hold the item the broken piece is in and drill absolutely straight.

You was a lucky guy.

has anyone ever tried left hand drill bits ? I dont know if they are made in sizes this small but im going to try and source some.Ive used them alot in my trade very sucsessfully.they are a better alternative to extractors and can save drilling and tapping a larger thread.well im off on search.

Not used left handed drill bits, but the left handed screw driver works well, you can get these from the stores if you ask for a long wait, they may ask you to take a bucket of sparks to the grinder, or is you are lucky give you a tin of tartan pain, sorry got carried away. I Couldn’t help myself. Laughing
