Wood Turning / sleeve position in gouge grinding jig
« on: December 04, 2012, 03:03:48 am »
Hello everibody, I have a question regarding the gouge sharpening jig: The position of the sleeve is important for a reliable and constant presentation of the gouge to the stone but the jig is lacking a way to repeat a position. In other words, is there a way to consistently set the sleeve in the same position?

Hello, just check my post on the chatter marks I left previously. The lubrication is extensively treated.
Regards.

Thanks, that is what I have been doing.

General Tormek Questions / Is water the only fluid for grinding?
« on: February 14, 2012, 01:09:47 am »
Hello, I have a workshop that is heated by expensive electric heaters. Often I do not use it for a few days so I would like to turn off the heater but then the temperature could easily drip below freezing temperature.
Here is my question. Since the grinding stone absorb water, as demonstrated by the reduction of the water in the tray when it is first immersed, I'm afraid it will crack if left wet in the freezing temperature. To prevent this, besides using the heaters would it be possible to use a different liquid for grinding or is the water the only lubricant? Would an antifreeze, perhaps the type that is compatible with septic systems be feasible?
Thanks.

 Unfortunately today I stated to have again the chatter. When the diamond reaches the third exterior of the stone one can hear an "harmonic  noise and this leads to the chatter marks which now are more thin and numerous. I noticed that the internal washer is   rubbing against the black nylon bearing (by the way are these bearings or bushings?). Could this friction lead to the  harmonic noise and then chatter? I will trying with lithium grease while waiting for the T-9 or the DuPont dry Teflon lubricant I found at Amazon.
If this will not solve the problem I will try the warranty but I do not know how this work.
I have another question: I have a 7inch Baldor grinder that I use with the extra Tormek universal support. It was not easy to find the right eight but I believe now I got a good compromise. My question is, can I use the TT50 to true the dry stone of the Baldor?
Thanks for the time and help.

Hello Jeff,
I did what you recommended and here is the result: no chatter. To be more detailed, the motor is NOT completely silent but the noise do not feel too bad, rather smooth.  In any case I did not have a Teflon based lubricant and used a spray lubricant for electric motors and also rotated the copper/diamond tip. Then I used the truing tool and got a chatter free result. Tomorrow I'll do a more extensive testing.  I did not do things in stages so I do not know if it is was the lubricant or the diamond tip to fix the problem. I sense that it was the lubricant since this morning I lubricated the shaft with Vaseline (did not know what else to use) and the chatter remained only in the 20% external part of the stone. The external part of the wheel is where the chatter marks where always more evident.
Thanks, Sergio

PS: You think I should ask for a new motor for the low noise? Furthermore, could you tell me which is a "Teflon based lubricant" that I should use? I also feel that the Nylon bushing are not too appropriate for a machine that all said and done cost $1000  and Tormek should think abouth an upgrade.

I was finally able to reduce although not eliminating the chatter on the stone. I removed the profiled leather honing wheels (LA-120) which I just recently acquired. In my opinion the vibration comes from the motor. The situation is annoying and wander if anybody has a similar problem.

Yes Mike, I tightened it but nothing changed.

The shaft looks OK. I removed the wheel and turned the inner washer which had the round side against the wheel so that now that side is against the shaft, reassembled the wheel and external washer and tightened the nut carefully. The chatter is still there.
So I tried to grind with the grinder on the floor to eliminate the possibility that the table was vibrating but nothing changed.
I do not have anything in mind. The good thing is that the chatter is very consistent (like a resonance effect on the lathe) and probably will not affect too much the sharpening. But certainly would like to know what cause it.
Also, when the wheel turns there is a vibrating noise that seems to came from the motor.
Hope someone will a solution. If necessary I can post a picture of the chatter marks.

Hello everybody, I have a problem of vibrations with my T-7 when using the truing tool TT-50. I've used it for years without problems and now suddenly and with no apparent changes I get a terrible chatter on the wheel. It started about two weeks ago and it seems to worsen with time. I've had changed the speed, lower or faster, of the diamond travel or kept it at ~ 90 sec. but no changes.  The wheel is apparently solidly secured. Can  anybody help me? Thanks a lot.
