I have a gryphette for doing my grooves.....have a problem....  The set screw that comes in the grooving bit now seems to be rusted inside, and I cannot change the grooving bit out until I get the old one off......any suggestions? We bought an e-z out, but the tip of it broke off inside the set screw.... Yes the screw was oiled before putting it on...and we also bought some spray lube that was supposed to loosen it up..... HELP!!!!!! pleeeeeze Thanks Marie |

Patients is key here, Marie.
If you're able to get something to grab the set screw or broken piece of e-z out, put some penetrating oil on it, lightly tap it (the vibration form tapping supposedly gets the oil working into the crevices) and let it sit overnight. Otherwise I think you're going to have to drill out that set screw. Bad part is that e-z outs are hardened, so you may not be able to drill it out.
Good Luck!
Nate

Is there a drill bit that will work? Something specific I should get, or use?

Sorry Marie, I wasn't on here long last night.
I just thought of something. This is a worn out groove bit correct? I would think you could CAREFULLY cut that groove bit off and ignore the set screw. Cut the bit in 2 places, preferrably 180 degrees form each other, and it should fall right off. Just be careful not to cut into the shaft it's mounted on.
A small cutting wheel on a dremel should work fine for this.

FINALLY got the bit off the machine...uggh...what a pain....
Went to the local parts store, and bought a bit that would drill stainless steel.....drilled 10 minutes, quit, 10 minutes, quit..etc.....cuz the drill and the bit on the machine would get hot.....but after a lot of diligence......and frustration, the bit is off there finally...
Thank you for all your help Nate...I really appreciate it....

I have had that problem, and I have spent upwards of 30-45 minutes playing with it.
It is a major pain in the behind!

Actually, they make easy out removers just for broken easy outs.
Before you put your new parts on your machine, go to an auto parts store and get a tube of anti seize compound. Take a little on a Q-tip and put it inside your set screw hole. Work it into the threads. Then also put a little on the set screw threads. The stuff is a little bit messy to work with, and hard to wash off your fingers, but well worth the inconvenience.
I'm not familiar with your machine, but I'd bet one part is brass, and the set screw is hardened steel. When you have 2 dissimilar metals together in the presents of water, you'll get corrosion. The anti seize compound forms a barrier between the the dissimilar metals.

Just a note: when drilling metal always drop some oil in hole being drilled to cool the bit. It cuts a lot faster and last longer.

Glad you got it apart Marie!
I never thought about anti-sieze compound. Good point Don.

Might be a good idea to put a light coat of anti seize on the shaft your bit fits on too. Especially if you plan to leave it on your machine for an extended period of time.
