I need an alternative.
The preferred size for a knife grinder is a 2x72. Like I said above, these get to be pricey. I ran across Wilmont a while ago: here. Wilmont makes grinders for sale, but also provides free plans for the "EERF" grinder. Hmmmm...right up my alley. A basic 2x72 grinder that I can build myself. Now we're talking.
I had a local machine shop that I've worked with for several years with my current job and my previous job quote me for making the basic parts. That came out to a bit over $600. That would send the overall cost of the project over what I can afford. Instead, I'm going to have them make the couple of parts that are too large for my mill. The remaining parts will be made by me. I'm modifying the design just a bit as I go to suit me.
The first few parts are already underway:
|The tracking wheel pivot. I enlarged the pivot holes to accept bronze bushings.|
|The tracking wheel bracket. Like the pivot, I enlarged the pivot hole for a bushing.|
|This part was originally three 1/2" pieces sandwiched together. I decided to make it from one piece of 1.5" aluminum.|
I still have a couple parts to make, including a platen and tooling arm. The tooling arm will probably wait until the pieces I'm outsourcing are complete. I already have a new 5" contact wheel. I'll need to purchase a drive motor, drive wheel, and tracking wheel. The two wheels will probably come from Wilmont. They're nice enough to provide the plans, so I should throw some business their way to say "thanks for helping poor dudes".
