    Hey guys first time posting on here. I have recently started trying to make some stock removal blades. Unfortunately with two kids, low budget tools and supplies is the name of the game for me. I quickly realized that buying a belt grinder would be out of the question for my budget so I started looking at diy options. I came across the jiffy belt sander conversion here...

    http://www.akgrinders.com

    Since a 4x36 sander is much cheaper then a big belt grinder (and I already had one) I was able to make my own version for super cheap. I used scrap from around my shop (free) and as I said I already had a sander ($145 at home depot) the only other thing I had to buy were wheels. I opted for the super budget version and used heavy duty caser wheels ($30 each) but you could eaisly use proper grinder wheels.

    And here it is on the 4 inch sander

    Belt tracking was an issue but a few wraps of electrical tape in the center of the caster wheels straightened that out. Works great with a 42inch belt. I don't have any 72 inch belts but I left the bar that attaches it long so it should work.
    Obviously not the best set up. It vibrates like nobody's business but since the 4 inch sander already has a belt tracking adjustment it was a cheap easy way to go.
    Hopefully will be able to post a few pictures of finished knives soon.

    Very good idea , I like it. What I like better is your selfless idea of thinking of your kids first, before new toys for your self !
    You must be a very good husband and father, and I tip my rhetorical hat to you!

    That's cool. I've seen the Jiffys before and thought it was quite ingenious. If you want to reduce the vibrations, try using a heavier bar to hold the wheels and maybe a fatter clamp.

    Good luck with your blade making!

    that's awesome. I really like seeing people make tools or upcycling and just generally being creative. (Dan C has been known to do that from time to time : ) Anybody can buy a kickass grinder (if they have the moolah). But how many people can MacGyver one? Props to you Steve-O. Can't wait to see what you do with it.

    I realize that this is a pretty old thread, but I'm just looking at doing the same conversion ( due to similar budget constraints). Has anyone else done this, and do you think 51x70mm skateboard wheels would work?

    Just make sure the middle of the wheel is slightly larger in diameter then the sides. This will help with belt tracking. And If I was to make this again I would turn the wheel holder 90 degrees so that the arm of the belt sander can be down when you use it. The vibrations you get with the arm up like it is in the pictures wear out the berrings and make it super loud when you go back to using it with the 4x36 belts

    That's awesome! I am currently using a 6"×48" belt sander. I was looking into using a jiffy sander to upgrade it, but I'm not sure it will work given that it's already at the 48" circumference. Now I know it's at least possible to make my own. Does anyone know off hand if the jiffy sander would be able to upgrade a 6×48 to use 2x72 belts? My concern is that the arm isn't the right length for my set up.
