If you have an old worn out belt that you’re going to throw out, cut it in half, lay it out on a flat surface and measure the length to get the total belt length. Double the length you just measured and you’ll have the total belt length. Measuring to ensure you have the correct belt length is a simple but VERY important process.
There are a couple of different ways to determine the correct belt size to fit your machine. The pictures shown are for a 1″ x 30″ long belt. If you have an old, worn out belt, simply cut the belt apart.
You can measure a brand new belt by easily first measuring the width, then laying the belt down as flat as possible without bending or creasing the belt in a way that will damage it, measuring from one end to the other, then DOUBLING the size as this is a belt and NOT a flat sheet in this instance. The second way would be to take your belt and easily measure the width of the belt. This measurement will give you your belt LENGTH. This is the best method for measuring your sanding belt if it is an old, used belt that you don’t care to use anymore.
If you don’t know the correct belt dimensions for your belt sander, there are four quick and easy methods you can use to determine the correct belt size. Tube Belt Sanders:Tube belt sanders consist of a pulley system that contours the sanding belt around tube-shaped surfaces. It’s very likely that your sanding belt will be one of several common sizes for sanding belts that we sell.
what size is my belt sander Related Question:
What is the standard size for a belt sander?
SIZE. The size of a belt sander is measured by the width and length of the belt. Belts range in size from small, detail-type sanders with belts that are only an inch or two wide to heavy-duty 4″ x 24″ machines. A common size for home shop use is a 3″ x 21″ sander.
How tight should a sanding belt be?
Most wood sanding applications require a belt tension near 40 psi. Because the goal is to keep the belt from slipping, users sometimes err on the side of using too much belt tension. Several problems can result from excessive belt tension.
What is the best speed for a belt sander?
The optimal speed for belt grinders is largely dependent on a number of factors, including type of abrasive grain, grit grade, workpiece material, and more. Generally speaking, a safe speed in most cases is 3,000 surface feet per minute. You can calculate surface feet per minute using the formula SFPM = RPM X .
What do I need a belt sander for?
Belt sanders are highly effective tools for removing roughness and preparing woodwork for less aggressive tools in the process like random orbit and finishing sanders. It is crucial to belt-sand with the wood grain rather than across it. Otherwise, the belt sander’s lateral action can ruin the work.
Why does the sandpaper keep breaking on my belt sander?
There are pretty much two reasons they can be breaking so quickly: the belts are old stock (or have been stored in humid or hot locations) or the tension is too high. Or both.
How do you tighten a belt sander?
If the belt is shifting toward the side of the sander that the knob is on, then loosen the knob by turning it about half a turn counterclockwise. If the belt is shifting away from the side of the sander that the knob is on, tighten the knob by turning it about half a turn clockwise.
What grit sizes are commonly used on a belt sander and why?
Choosing the Right Sanding Belt Grit The heavier the job, the coarser the sanding belt you’ll need. 40 to 60 grit is best suited for the heaviest work. When you’re performing tasks such as smoothing surfaces or removing minor blemishes, you’re better off using sandpaper with 80 to 120 grit.
Should you push down on a belt sander?
You do not have to push down on the sander. Pull the sander backward letting the weight and sharpness of the belt cut the surface. Don’t pull back and then tip the sander off the edge or you’ll cut off too much wood and need to build it back up with putty.
How much wood can you sand down?
I’m not sure where sanding comes into play here, but yes, you absolutely could sand a 1/2″ off of a piece of wood. It will take some time with a belt sander and even more time if you’re doing it by hand. (On the bright side, you’ll build a good bicep that way!)
What is better belt sander or orbital sander?
A belt sander is more effective for large materials, while the orbital sander is ideal for small spaces and pieces of furniture. A belt sander works effectively on flat surfaces, while an orbital sander can work with various angles.
How do I determine my belt speed?
Calculate the belt velocity by multiplying the circumference of the pulley by the speed of the pulley. For example, the drive pulley has a circumference of (Pi)(D2). This equals 2(Pi). The speed of the pulley is 1,800 rpm.
How many RPM is a belt grinder?
Belt Sander/Grinder provides motor speed of 3,600 rpm.
