Random orbit sanders are much more efficient (fast at removing material) than regular palm sanders. Just be careful because they can be very aggressive. You may need to hand sand prior to finishing, to remove swirls from the RO.

I have a heck of a time with my random orbital sander, especially when I'm trying to lightly sand. For some reason, it 'grabs' the wood at the start if you're not super careful. Haven't tried it on aluminum...

I didnt realize the orbital sanded faster than the regular. It took me forever to get down to bare wood while sanding in the compact. Do you think maybe I should try the orbital for sanding in the Airflyte? or will the birch with the amber shellac be easier to sand then the ash with the milker finish that was in the compact. This is the one I have

I have a heck of a time with my random orbital sander, especially when I'm trying to lightly sand. For some reason, it 'grabs' the wood at the start if you're not super careful. The early RO sander and many new cheap ones, the sanding pad starts spinning in an orbital circular manner if you start it up in the air. When you start it and then place it on the wood you are in effect hitting it with a disk sander for a second or two till it starts it orbital action. I tried a cheap one and hated it. Then I ponied up for a Bosch and the difference was night and day. I am on my second Bosch RO sander and it is much better than the first. Not idea what they changed but the new one doesn't spin the pad like the old one. You can start it in the air and it doesn't gouge of leave marks. It has taken me many years to come around to this line of thought but if it is tool that I use a lot, I gripe and fuss but spend the money on the good one. (After researching and reading the reviews! ) PS. Corrected my terminology. And you should always start a Random Orbital Sander in contact with the wood.. or whatever to prevent gouging.

I love my HF palm sander. It makes fast work of removing layers. I’ve used it with 60 grit for rough sanding and some 220 grit for finer sanding. One thing I have learned is that the harbor freight paper is crap and doesn’t last long at all but the paper at Lowe’s costs a little more but lasts a lot longer.

I agree, HF sandpaper isn't very good.
My orbital sander is an 18 volt Ryobi. It works better on the panels if the battery is a little low..variable speed the cheap way. LOL.

I would use the palm sander you have (or hand sanding) for interior refinishing. Random orbital sanders are very aggressive and remove a lot of material quickly. Kudzu mentioned something about starting the R.O. sander before making contact with the surface. Best to start it while in contact or it could cause serious damage because it'll be running at very high rpm. I'd suggest practicing on scrap material to get a feel for what you'll experience on the real surface with either machine.

I never use the HF sand paper, usually use HD or lowes paper on the HF sander.

Sanders are tools that use consumables. That being the sand paper. So when you buy a cheap sander they get you on the replacement sand paper. Kinda like Kodac who came up with the idea in the first place that if you sell the machine cheap enough everyone will buy it and then you make your money on the film. Copiers and Printers work on the same basic idea. They get you on the consumables and repair contracts.
I use a mouse sander from Ryobi. But I buy the sand paper in huge lots from Amazon.

I agree, HF sandpaper isn't very good. I go through a fair amount of sandpaper building the boat kits and one thing I have learned is the middle of the road to higher priced papers are the better value. You only save money up front buying the cheap stuff. You go through it so fast that the more expensive paper is actually cheaper because it lasts so much longer. That has not applied to bandsaw blades or jig saw blades though. Plywood eats them up pretty quickly.
