Metabo SR20 23 1/3 Sheet Orbital Finishing Sander Logo
Posted on Apr 18, 2009

I have a Metabo SR20 23 1/3 Sheet Orbital Finishing Sander. After three years and very occasional use it stopped working properly. Now it only moves very slowly. Moreover, the screws that holds it together are neither phillips heads nor hex screws, so it is difficult to attempt to fix it.

The screw are Torx size T15. Sears and most hardware stores will carry them.

The most common cause of this type of failure is bearings. Dust will settle on the bearing. Through capillary action, the dust will eventually dry out the bearing. This can happen even if the tool is used very little. Blowing out the tool with compressed air after use can help prolong bearing life.

The standered screws in the sander are Torx. You will need a torx 15 or 20 (cant remember which) to take it apart.

How do I switch from orbital motion to straight line with craftsman dual motion model 315.116120?

Looks like a standard belt sander. If it does orbital as well there must be a switch on it. I can't find a manual.

Strangely, this is also listed as your model and this one is definitely a straightforward Orbital Sander.

Ah, I just noticed from the first link, the image is wrong and the parts schematic shows a plain orbital sander. It only has one function!

How do I use the random orbital sander?

Random orbital sander is relatively easy to use and control. You can get a lot of work done using a random orbital sander by spending a little amount of time. But, there are some things that you should keep in mind to get the best use of the sander. In this article, we are going to show you how to use a random orbital sander to its full potential.
There are many brands out there in the market right now. Each offers a different style and different controlling functions. But, the core elements of each of them are the same. The random orbital sander gives you the free and easy usability. Plus, the finishing that these sanders provide is unparalleled.

THE USE OF RANDOM ORBITAL SANDER

You can use a random orbital sander to achieve versatile woodworking functions, but mainly it is used to give your material a more smooth texture. Usually, these tools come with a lot of power so you can work on rough materials and get quick results. The design is very compact so that you can work with ease, even with one hand. So, ultimately this is a sander that will give you great power and control in a compact body.

HOW SHOULD YOU DEAL WITH THE TOOL?

Keep the Object Locked
Make sure that the object that you are working on is properly locked. Keep it secure, so it does not move too often. This way, you have had more control over the job.
USE EVEN STROKES: You should apply even strokes in every part of the object to make sure that they are sand properly. This will result in a smoother finishing to your object.
USE VENTILATION IF NEEDED Try to remember this when you use a random orbital sander, keep the ventilation on. It creates dust particle that cannot be easily controlled. So, you should keep your ventilation on to avoid the debris in your mouth.
CHOOSE THE RIGHT KIND OF SAND PAPER Different kind of wood respond well to different kind of sandpapers. So, you should look out for what is best for you and then buy your sandpaper accordingly. Make sure to properly place the sandpaper on your sander and that your sander head is clean at the start.
DOUBLE SAND THE EDGES: It is always a good idea to double sand the edges if you are looking for perfection. This allows the object to have a more fine tuning and luxurious look.

THINGS TO KEEP IN MIND:

  • Do not change the disk of random orbital sanders very frequently as it will not be cost-effective. Use it until the very end.
  • Do not apply too much pressure while working on the edges
  • Add vacuum if you want to keep your station clean.
  • Sand with a steady hand and turn up the power for rough woods.

Yes, I am on my 3rd one. Your machine has destroyed itself, and must be replaced. Sorry about that. If you choose to do so, you can take it apart and see what I mean. ( I fix these).

I just aquired a used Skil Model 409 orbital sander and am having trouble inserting the paper. Is there a technique peculiar to this machine that?

Sorry, I was missing that part. You got it right, though. three hands is the answer. Orrr, you could go get some nice sticky back papers and cheat. They come in a variety of sizes or can be cut from full sheets. what you have there is a good sander to use while you figure out what kind of sander you want:)
Best regards, Farmerbear

The vibrating plate stopped vibrating but the motor seems to be working ok. Either the plate is jammed or something broke. What do you think? This sander is probably 30 years old, very heavy duty.

check the bearing in the platen, it is probably seized up. you can go to Milwaukeetool.com and download a breakdown for this tool. Let me know and I will try and help further.

Ryobi half-sheet orbital started screeching - any way to lube it?

Take that sander apart and you can oil the roller externally with a good lubricant not a gel like substance but oil that is made for things to move better. Doesnt have to be heat resistant after you have oiled both sides with the belt off. Then turn it on and let it mix. You may have to do it a few times to get it to work well again
