Mortising machine chisel sharpening

How do you sharpen the chisels for a mortising machine?

 

I know I can get a round (ball shape) stone for a dremel and touch it (carefully) to the inside of the chisel, but I am not sure that is the best way, and would probably need 4 different sized stones for the 4 chisels (1/4, 3/8, 1/2, 5/8).

Plus, I am not sure a stone would sharpen the chisel enough.

I do know NOT to sharpen the OUTSIDE of the chisel, as that will change the cutting size of the chisel.

You can hone the outside of the chisel to deburr the cutting tip, so long as you're being gentle about it.

 

But for honing the inside of the tip one of THESE from Rockler is the ticket.  While it may look like you chuck it into a drill press or a hand drill, but you don't.  It's strictly hand operated.  This keeps you from doing unfortunate things at power drill speed.

Matt's advice will give good results to be sure. I've spotted this baby though and am just looking for the opportunity to get one and try it out: http://www.monstermarketplace.com/woodworking-supplies/dremel-5-8-round-nose-cone-aluminum-oxide-gri...

I bought a set of stones from Lee Valley that do a nice job. If you have Clico chisels, I think they may be ground at a slightly different angle.

Rick, thanks for that article.  I always have trouble keeping my bits sharp and I think that will really help.

+1 on Matt's suggestion. I have that setup and it works great. The handle also doubles as a holder for 1/4" screwdriver bits.

Not true.  Honing the outside surfaces of a mortising chisel is one of the required activities for top-notch and clean mortises.  You want to hone to outside surfaces to the same degree as you hone the back of plane irons.  This makes for easier entry into and exiting the wood and leaves smoother surfaces.

Re: Mortising machine chisel sharpening

Understood Howard, but SHARPENING the outside is a different activity from HONING, which is what I was trying to get across in my post.
