I am wanting to make a "flat platen only" grinder. I already have a Wilton Square wheel grinder, with a flat platen, but I want a second one with about a 12" flat platen so I don't have to keep switching back and forth. I have friend that sell motors wholesale, so a 1 hp motor or so will be no problem. I also have a friend that works in a machine shop that could help me out with the details regarding the construction of the grinder.

Any suggestions for plans? I could perhaps engineer one from a good digital photo or two as well. Any help/suggestions at all would be very much appreciated.

Thanks in advance,

Hank
 
I would suggest a google search. Their are a lot of creative people who will gladly show design, pics and even advice. Not saying people on this forum are not creative we know that is not case at all.
 
Here are some links to photos, plans and tutorials for home/shop made grinders (not all are for flat grinding only):

Edit: Darn it, I see a lot of the links to the flat ginding machines are bad since keen junk went away. Let me see if I have the photos on my hd.

Is it possible to make one for less than a fully assembled model, such as the grizzly?
 
Sure. The usual thread goes like this:

"I went to a junk yard where I found a a truckload of variable speed dc motors and controlers, just for the asking. Well I live right next to Beaumont metals, and one night I was dumpster diving out back and found a fully assembled moving platen they had thrown out cause it had a scratch on the metal. Next day while checking the classifieds under "free miller welders", I found a Dynasty 200 dx!..."


Seriously it is a pretty simple device, with good scrounging and the tools to take advantage of it you should be fine. I like the Beaumont site, since they sell good parts, and have a section on home made machines.
 
It is simply amazing how many talented people there are in the knifemakin' world. I was truly deprived by working in a shop where everything was provided and inovation was not encouraged. It's gonna take me forever to sort through all this material and figure out what works for me.

I have another question on the motor, why a variable speed DC ? Protactical made that statement and I noticed one of the people cleaning out their shop was also selling a DC motor and controller. Thanks Steven
 
Variable speed is a big plus (fast for hogging/slow for detail work). The DC setups generally cost a little less than the AC setups.

Thanks Ripper :D Being an electrician the DC thing got my attention. I did not know that they would be cheaper too.
