  • 2 x 72 belt grinder kit

    Is there a Canadian equivalent to this:

    It'd be nice to avoid border charges. The CAD file is available so I guess that's always an option.

    Anyone interested in cutting one for me?

      I have been pondering building a belt grinder for a long time, but I just can not get over the price of all the contact wheels they require, and I haven't found a suitable 3PH motor so I can use a VFD for variable speed.

      That does look like a nice setup though...

        What's required for suitable?

        Tons of motors on ebay...

          Hi Greg,

          The Polar Bear Forge kit is a pre-made set of EERF Grinder parts.

          EERF is free spelled-backward -- it's a take-off of a Bader grinder in the form of .dxf (CAD) files that you bring to a local water-jet shop and get it cut out of plate:

          http://blindhogg.com/eerfgrinder.html



          "I hope this article helps encourage you to build this grinder. The photos below will show the steps in how I built this grinder along with the blueprints necessary to create the grinder.
          The tracking wheel and drive wheel I purchased from Beaumont metalworks. If you have any suggestions or have a question please feel free to email me at blindhogg(atsymbol)aol.com

          Recently Jamie at polarbearforge.com has offered this grinder in kit form that you can purchase if you can not get it cut locally for a decent price."

            Here are a couple links:
            http://www.beaumontmetalworks.com/ seems to be a HUGE supplier of parts-including contact wheels. Most of the home-built kits are copies of their KMG grinder ore the Bador that Lazlo mentioned.

            The "no weld grinder" is popular also: http://www.mickleyknives.com/html/no_weld_grinder.html but you still need to buy contact wheels. It's very easy to spent well over $500 building one.

              Grizzly sells a knifemaker's belt grinder with an 8" contact wheel. They sell an optional 10" contact wheel for under $100.00, which is considerably less than I've seen one anywhere else. I used one on a 2x72 grinder I built.

                -Just keep in mind that Grizzly's wheels are drive wheels as well as contact wheels. Meaning that if you want to use one as a free-spinning contact wheel in a KMG-style grinder, you have to bore the center for bearings.

                      That looks good too though I'd likely opt to weld it.

                        If you're not afraid to weld, I'm about halfway through Michael Clerc's outstanding copy of the Beaumont KMG. The plans are hosted on Don Fogg's web page, and they have Rob Fink's blessing:

                        Here's Michael's excellent build log on Blade Forums:
