A grinding wheel, it takes practice but you'll get it.I was wondering if you guys had an easy method to sharpen your lathe bits like new? I have used a mini wheel grinder, but they don’t seem to come out fresh and sharp like new one’s? Any suggestions?
Thanks,

For all my other cutting like reducing ferrules and tips and other materials I use replaceable insert bits that stay sharp for much longer even on tough materials but have a small radius to them. The work horse bits if you will.

What are you using. Where did you get them. Are they sharp out of the box.
Just curious... can bits be send out for professional sharpening. I have a few similar to Kamik's
I know you asked about sharpening but here is another option.
You can use TCGT 21.51 and 21.52 inserts for aluminum. One has less of a radius on the cutting edge than the other.
You will have to buy a set of holders for these bits and adapt them to your setup.
They stay sharp for a long time and cut really nice. They are pretty cheap on Ebay.
I use a diamond sharpener (from Home Depot). One side is coarse, the other fine. About 20 dollars. If you use a grinder there is a chance heat will build up quickly and ruin your bit. With a little practice you will have them sharp with the diamond sharpener and not have to worry about heat.

I typically buy new. I am thinking about changing over to using inserts. What are folks using for the smaller lathes (hightower, Mid America)?

For those who like to use high speed steel like myself. There is something being overlooked on the sharpening. Keeping the bit cool when grinding might sound like a good idea but if it gets hot while grinding and then you dip it in cold water it hardens the surface and makes the bit hold its sharp edge longer. That is why those of you who use diamond files have to keep sharpening so often.
Sharpening carbide is totally opposite and keeping it cool is better.
