Components for belt sanders

A belt sander could be broken down into to the five parts described below. Consider each component independently if you really want to make a belt sander but aren’t sure where to begin.

The framework. Steel is most commonly used; however, wood can also be used. The metal frame is often welded together, but it can also be bolted together. On Craigslist, you may even get a weight lifting table and break it apart to use it as a frame.

  1. The casters. Pre-made belts sander wheels are available from Beaumont Metal Works, although they are expensive. If you understand how to machine, you can create your own wheels. Wheels can be found (skateboard wheels are the favorites). You can also make your own wheels out of wood or MDF in many layers. Idler wheels are easily removed from engines. For proper tracking, the wheels will have to be crowned. Crowning could be done manually or with masking tape. The backing of the 2×72 belts, however, can wear down the crowning.
  2. The source of power Almost always, this will be an electric engine. A new motor can be purchased. Remove the engine from an existing object or appliance to save money.

Getting a free treadmill from Craigslist with a good motor and controls to allow you to regulate the pace of your palm sander is a popular trick. Inspect the treadmill belt and notice how old the more frequent buttons or switches are to get a rough indication of the treadmill’s motor’s condition. A treadmill’s motor will almost always be in perfect condition; you won’t be acquiring a treadmill from such an Olympic athlete. Consider looking for treadmills on Craigslist using misspellings; in this case, the most prevalent misspelling of treadmills is “treadmill.” It’s also sometimes spelt as two things: “tread mill.”

Here are several movies that demonstrate how to identify and wire treadmill engines for use in household tools.

A bench grinder is a popular choice for converting an existing instrument into a belt sander. An electric drill or even a rotational tool like a Dremel can power smaller belt sanders.

Dust and debris will be protected by a sealed motor. You can also construct your own protected shelter. You won’t know how awful the noise is until you use the sander for the first time. Simply consider vibration-reducing mounting options for the time being.

You might wish to alter the motor speed, and a step pulley is a good way to do so. After compensating for speed modifications via a fast switching, a single pulley, or another mechanism, some designers find that they seldom use the varying speeds.
