Venturing into MDF sharpening on a bench grinder

[COPIUOS]

Evening Gang,

Watched plenty of videos, got a used bench grinder from a buddy, going to start tomorrow at a friends shop...

Any advice going in? I have seen them do it with just the MDF wheel and some compound...

Advise any other steps? Any tips/tricks before i jump in?

Thanks as always.

If you're set on going with a bench grinder, this would be a really good place to start:

paper sharpening wheels - when your time is important to you

My only advice is don't let the edge get too hot. While I'm not 100% sure, I can't imagine that paper wheels remove steel as easily / quickly as an abrasive belt. Good luck in your research.

ETA - Actually, one other thing; Go to your local thrift store and buy a bunch of larger junk kitchen knives to practice on first.

Cam,
Just get a few cheap blades and practice on them. Once you get them to where you can file off the edge then put it back on and feel good about it start on your good stuff. I like a belt grinder better because i can convex easily. But the the wheel works well also for touching up blades. If you want to re profile stuff a 1x30 is where to go next. And same goes. Get a cheap blade out and work on it. Then file it flat and start over. Took me about 2-5 times with each setup to get ok at it. Now im good. But it can always get sharper. [emoji12][emoji109]

SUCCESS! Had to make more mods to the free grinder than anything - very fun project, some good ole cajun engineering at work. It is amazing when you hear about something like that and it is actually EASY to produce the results...I am no pro yet, and I've got a few very sharp Busses and kitchen knives I practiced on now...got 2 really really sharp stripper tank busters, pocket knives so easy and fast, portable machine can set up out side on nice days.

Look forward to perfecting the techniques for this. Do want a convex set up as well...

Got a 2-sided job so I can do each side of blade very comfortably away from the other wheel...

What a good day, although I got lost in the project and forgot errands...

Appreciate the advice.
