    Default Need plans for belt grinder

    I would like to build a belt sander (grinder?) with a narrow 1" or 2" wide belt. I will probably combine a disc sander and table, and enable slack or platen sanding. Belt length does not matter as I can have them made up locally. Does anyone know of any plans for something like this?
    Thanks, Greg

    Do a search for no weld belt sander. A guy in Minnesota sells the plans. He is also knife maker. Years ago copied a 1" Kalamazoo. Does work for light work. Deburring and lawn mower blades.

    Wheels and Ideas can be had here. Good people to deal with. If you do some digging around there is a lot of good info on the net. I dont see it in my book mark right now. All so there is one book out there that is fairly good. Can't lay my fingers on it Some thing like Making a knife grinder for under $50 he has wrote a couple of books on knife making. The biggest challange I had was finding a motor that I like and was big enough and pully size.

    There are many pix to get ideas from plus links to machine, components and parts suppliers.

    The Beaumont grinder is impressive - they offer a group of excellent videos showing uses for their machines.

    Take a look at this video.

    Kind of slow and dry but worth it.

    I built this one about a year ago.

    I used a 2 hp three phase motor with a vfd for variable speed. It works well. The plans are not great, but there is enough info to build a grinder. The guy has an annoying habit of referring to square tube as pipe, and then in the next sentence it is tube again.

    plus, the plans are free

    Is it just me or are both those DIY grinders the most unnecessarily complicated designs have ever seen? I've looked at building them both and think if I were going to that much trouble, I'd go ahead and build a larger unit. Labor would be the same and materials very little more.

    As for the cost savings, light-duty grinders/belt sanders show up on craigslist and yard sales fairly regularly at a reasonable cost. I have two 1"x42" sanders I picked up for $25 each. I also picked up a 4"x48" edge sander for $100. The heavy-duty 6"x48" units come along less frequently, but There are two for sale locally just now.

    thnx, jack vines

    This one is elegant, excellent design and very rigid with easy to install accessories including ones for knifemakers. No tubing in this one, barstock and plate. Good sharp video you can download; view with Gomplayer, use frame capture for stills of details.

    Default Building Mike Clerc design belt grinder

    I am well into building the grinder suggested by A77 at http://www.metalwebnews.com/manuals/knife-grinder.pdf. The plans are very good. I plan to incorporate some details from the Viddler video, too. His accessory changing design is very fast, and I can get by with just one arm, especially if I use both ends. I'll put up pictures when I get it alittle further along.
    Thanks everyone for your help.

    I built the one drawn by Mike Clerc with some features on that Viddler video. It ended up fine, and works very well for wheel, platen, or slack sanding or grinding. The motor is a 2hp controlled by a VFD.
    Thanks all for the help.

    Nice looking rig.
    I might just have to whip one up.
