Well, not as old school as a block of wood with sandpaper wrapped around it, but almost.
Here’s the deal. I’m just now getting back into WW after dabbling in it a couple times over the course of my half century on this planet.
During that time, the “normal” kind of sander has changed. I need to understand if this change is as stupid as it seems or I just don’t get it.
Back in the day, your typical power sander did NOT orbit anything, randomly or otherwise. “Back when I was a kid a sander always went in a straight line…we didn’t have none of this new fangled orbitational nonsense!” “Hey, you kids…get off my lawn!”
So, over the years, somebody convinced the public that a sander should wiggle around aimlessly and by doing it randomly enough, it would still rub the wood mostly the wrong way, but since it is random, maybe you won’t see big circles etched permanently into the surface.
Anybody who ever picked up a sanding block quickly learned….you go with the grain, not every which way.
Please educate me. Why do almost ALL of the sanders out there orbit randomly instead of going back and forth like they used to (back in the days before this insanity befell the planet).
I managed to find a small number of such sanders out on the inter tubes. Here is an example of a right and proper sander:
It seems to me an ROS might be acceptable for something like auto-body finishing or getting rusty flaking paint off your metal lawn chair…but for wood working????
I’m thinking it makes more sense to use a stationary belt/disc/spindle sander to change the shape/size of a piece…but when it comes to finishing it, back and forth makes more sense than orbital. I just don’t see how ROS fits into the mix for WW.
