I had a thought to use my drill press to grind my planer blades.
Basically, kerf-cut in a block of wood to match the bevel, chuck some
sort of grinding wheel in press, run blades under grinding wheel at
slow speeds.
Certain that I'm not a genious, I figured someone else would have
certainly figured out the same thing. So I googled it and came up with
the reference below. I'm wondering if someone knows the article Jack
is referring to. Any other references or tips for doing this would be
appreciated.
BTW, I can do sandpaper sharpening of the blades, but I would just like
to have a technique that will move faster for removing nicks before I
move onto sandpaper sharpening.
Thanks,
Phil

The point is, if he's going to send them out, send them to a tool grinding
shop, not a machine shop. The prices are going to be much better. If he
insists on the tool maker, send them to me. $80.00 .

You likely won't find a cup grinding wheel with the type of shaft you can
chuck in a drill press and if you do, it will be of questionable usefulness
for what you are doing. Get back with MSC (or any industrial supply) and
find out about Morse taper shanks to adapt the drill press to a grinding
wheel. If you have to "hammer your chuck off", you're doing something wrong.
Hopefully, you have a drill press with a Morse taper socket. They come out
real easy and are designed to do so. If yours is the type with a taper
machined on the shaft, you probably won't be able to find an adapter. If you
have this type, you may have to have something made.

Or, you may have a drill press such as an old Delta with removable
spindles. One of the optional spindles has threads and flanges for a
cup wheel.

You are considering a proposition that will give you a world of grief. A
drill press is not a surface grinder, and the precision to do an excelent
job on sharpening planer blades is a tough thing to get as you need three
exact knives.
The easy way to get this is to take the blades to a tool and die maker. In
a few miniutes he can give you back perfection and have zero risk of
screwing up the temper of the steel.
I even bet you might be able to find a guy that would be happy to trade his
skills for yours, but even if you cant the cost to sharpen the knives is
going to be nominal.

I suppose any machinst that was competent on a surface grinder would
suffice, but most of the time the tool and die shops are the ones that you
find the surface grinders. Make a few phone calls and ask for pricing. You
may be plesantly supprised.

I think you mean a tool grinder. While a tool and die maker could do a very
good job of it, you wouldn't want to pay his shop rate if he would even be
willing to do it.

Actualy I made a "wheel strop" for honing plane blades and chisels as a final.
I cut three discs (each 3/4" thick) on a band saw and finished the sides on a
disc sander once glued and dried, 2-1/4" thick. Leather disc on top of that.
The top piece of particle melamine(?) for flatness and the two lower of basic
ply. All wetted and clamped with gorilla glue. Worked quite well, still need to
make a base that holds the bottom of the "shaft" for stabilization (bolted to
the drill press base which has slots (it's a small bench top type), let's call it an
"arbour", which I had made by a local machinist.
The rod of basic 5/8" cold roll threaded for the bolts that clamp the wheel with
two different OD sizes of 5/8" washers, for the top and bottom. The top 1"
turned down to 1/2" and chamfered for the chuck.
Real nice fellow, gave me a damn nice deal of $20!
Just some addendum for your imagination to work with, hope it helps,
