    Default My new belt sander

    Well new to me that is

    I'd been planning on making a belt sander but came across this one. Its about 1100mm between the centers on the pulleys and came with 10off 50mm wide belts.

    First job was to pull the switch so I opened the box. One of the wires pulled out of the switch without undoing the screw, two of the other screws were screwed onto the insulation. The insulation on the earth wire didnt look good either. So I opened the box on the motor. Notice the blob of copper on the bottom right terminal.

    I'd seen it running so wasn't to worried(although an earth that works could be handy lol). Wired it up to the VSD, sounds like the bearings could use some grease, but other than that all is good.

    Think I did ok for $100

    Gotta love bargains like that. Just the belts would be worth nearly as much as the purchase price.

    That's a funky work angle on it. Would take a bit of getting used to working on the platten at that angle

    Good score Stuart, better than paying for the little underpowered ones at Bunning etc.
    Has it been made or is it a commercial job?

    Hi Method,
    Yeah its pretty high and the guy I bought it from said he had cut the legs off it.

    Hi Dave,
    I have one of the 375W bunnings ones, they are ok as long as you aren't in a hurry lol, damn its gutless, 3hp should fix that . The drive and tension wheels are commercial, the frame is made up. Its so heavy I might not need to bolt it down.

    Good robust looking machine at a great price. Could you modify the belt to be vertical and then you could add a nice workrest to work off, I find this is the most used attachment bar on mine and it can produce very accurate 90 degree finishes. By doing this you can also place a partially water filled bucket directly underneath and collect most of the dust. As yours is at present you are going to be covered in grindings real quick.

    Hi Bob,
    I have a few ideas going through my head but they will have to wait a little
    I'm thinking something along the lines of. Motor mounted on a plate on the floor, a post coming up with the arm able to rotate around it. That might be a little over the top though.
    I'll see what the balance is like if I extend the back legs. It looks like it could be tipped forward a long way without falling over.

    I assume the work piece needs to be after the tension/tracking wheel and before the drive wheel?

    The motor has an enclosed air cooling tunnel around it

    Hi Stuart,
    The work is usually placed between the drive and tension wheels. This link is one with a few different designs that could give you a few ideas. CNCCookbook: Belt Grinder Ideas

    Great score Stu. Looks like it will make a great missile launcher.

    Hi bob,
    So many good ideas in that link. Now I have no idea what to make

    Anyone know some where that sells joinning tape? Am I going to have to sit down before I read the price?
