Micro-Motor Burs

[woodturnerjosh]

Hi All,
As my name suggests I am mainly a woodturner, but don't hold that against me Smile, I have been recently going through a lot of previous posts but could not find an answer to my question. I do apologise in advance if this has been covered but I recently (today) ordered an Optima micro-motor for detailing my carved turnings and the bit that I use most in my flex shaft tool is a 1/8 shank 1/8 round ball double-cut tungsten bur. So my question, finally, is this too large a bur for a micro motor? I know, I probably should have found this out first but it is often said that I do things backwards.
I was also wondering what the maximum diameter bur you use in your micro motors is.
Again, sorry if this has been asked before.
Thanks
Josh

It will pose no problem whatsoever. I routinely use 1/4" Typhoon in mine.

Thanks Doug,
That is a relief (no pun intended).

Doug, I have to ask.....what brand of Micromotor do you have that will take a 1/4 inch shank? Did I misunderstand your answer? I didn't think any micromotor even comes with a collet that large. I am sure I'm having a blond moment here and misunderstood what you meant....
Could you please clarify that?

I have an Optima and a Brasseler. He asked about the bur, not the shaft. I use a 1/4" bur on a 3/32 shaft. He could also use a 1/4" bur on a 1/8" shaft. His 1/8 " bur on his 1/8" shaft is what he was wondering about and should be fine. Read his question again Susan.

I thought I was probably having a blond moment, Doug. Thanks for clearing it up for me.

I should have known to be VERY clear. My wife used to be a blonde and I have 3 blonde daughters. And yes, I send them every blonde joke I find.

Well, I suspected that I was mistaken but I had to ask....I mean, if there was a micromotor out there that could handle 1/4 shafts, I would just HAVE TO BUY ONE! Whether I needed it or not. I mean, can't you just hear Tim-the-tool-man-Taylor grunting in the back ground????
I would want one of those......wouldn't you?

But yes, I am a blond by birth, and blond-er by choice. Years of peroxide does terrible things to the brain.
