2x72 Grinder Wheel Set

2x72 Grinder Wheel Set

I am building another low-cost 2x72" grinder and I am super fortunate to have made a friend at Oregon Blade Maker.


Marinus at Oregon Blade Maker is offering some high performance, yet light-weight and durable grinder wheels for a low cost 2x72" DIY build.

These wheels are computer engineered, glass-filled nylon (durable composite plastic) with 1616RS bearings.

The wheels in this set are two 2-1/4" wide x 2" and one larger diameter crowned 2-1/4" wide x 3" which is designed to assist in belt tracking.

The wheels will mount with any 1/2" bolt. Plan for three 1/2" NC x 3" to 3-1/2" grade 8 bolts and suitable nylon lock nuts and washers.


These are low drag and spin freely.

Of course, the OBM glass-filled nylon wheels are not going to take over the aluminium premier wheel's top spot in roller Olympics, but these OBM nylon wheels offer value that cannot be denied.

  1. I tried to find an e-mail link for you but couldn't so I will post here. I wanted to let you know that this is my new "go-to" site for knife making! I am just blown away at your kindness to take the (I'm sure large) amount of time to post the tutorials and photos. I am disabled currently and can't afford hardly anything, so your DIY belt grinder etc. is a true blessing to me. I am also sure that all the things that you do for everyone will come back to you ten fold.

    I also really wanted to let you know your hard work has not gone appreciated and wow you make some beautiful (and I'm sure very well functioning) knives!

    1. Hi Thom,

      Thanks for your kind words. Where there is a will there is a way and not everything has to cost a lot of money to work well.

      All the best!

    1. Hi Phil,

      Thanks for your kind words and for letting me know about the shipping destination issue. I have worked with OBM in the past and they shipped to Canada then. Perhaps something has changed. I will check into it.

      Regards,

      Dan

  3. Glass filled nylon is some tough stuff. I agree, for the price I wouldn't be afraid to use those wheels.

  5. Dan,

    I have been using these same glass filled wheels on my belt grinder (which I used your plans) and have not had any issues whatsoever. As for ra Kessler, I modified and used a 25 pound gas spring from Princess Auto (Harbour Freight equivalent)here in Canada. Works great and I think I paid $12.00 for it.

    1. Thanks for this Chris. I am building a second grinder and using the OBM wheels. Pretty hard to beat for the price.

  7. I'm in the finishing stage of my DIY 2x72 belt grinder build and am designing the motor/drive set-up this weekend. I'm planning on using step pulleys and a jack-shaft arrangement. What belt speed range in SFPM would be desireable? I will use a 1725 RPM 1 HP motor and am considering 4-groove step pulleys....I'm just not sure what size steps to purchase. Suggestions?
