DIY 2x72 Belt Grinder for Knife Making, Study Guides, Projects, Research of Machine Design

There are tons of options for 2” by 72” knife making belt grinders. Fewer reliable and well-reviewed options exist for one-inch wide belt grinding alternatives. For this reason, we have discovered three hardcore, reliable options for one-inch belt grinding.

Reliable and heavy-duty belt grinders

by James Pagan on November 21 In general, there are three basic elements of the belt-grinding grinder: work rest support, grinding head, and a regulating head. These components differ for all the methods but in general, the workpiece is pressed between the grinding head and the rest support. The objective of the regulating head is to coordinate the belt pressure.

Most standardized belt configurations follow the 2” by 72” belt size. This size accounts for over 90 percent of belt grinding machines manufactured in North America. Common grinding machines include: ● The Burr King 972 Knife Maker Belt Grinder ● Wilton Square Wheel Belt Grinder ● The Hardcore Grinder Knife Making Belt Grinder ● KMG-1 Knife Grinder ● The Bader Bill Knife Making Belt Grinder Wish List My wish list for my new grinder would be:

  1. 2 x 72" belts
  2. 1.5 to 3 horsepower
  3. Variable speed
  4. Removable attachments, platen and contact wheel Variations Before building I considered some variations: Stepped sheaves for varying speed. This would be a lower cost build but still allow some speed changing. I would need two pillow blocks, an axle and stepped sheaves (or pulleys as some folks call them). The drive wheel could be 4" diameter still. This arrangement would let me use any motor, whether it can be reversed or not.

I put a backing piece of 1/4" plate behind the angle to step it away from the plate. This could be accomplished with a small stack of flat washers as well. This space is to bring the platen directly in line with the belt and wheels. If you need to tweak the platen to the left or right, add or remove a washer from three bolts securing the platen to the plate. The wheels are mounted typically with 1/2" bolts. In my case I have metric wheel bearings, so 12 mm bolts. The wheels cannot run against the plate, so I made some spacers from schedule 40 3/8" pipe cut into short sections about 1/4" and with a hacksaw and shaped with a file to a uniform thickness of close to 3/16". Slip the spacer over the bolt, slide the wheel on and the inner race should be kissing the spacer. READ MORE ON OUR WEBSITE
