Topic tags/keywords: sander tool porter cable 505 505 random orbital sander orbital question

Hey guys,

I bought a porter cable 505 finishing sander used and it seems quite nice, however I have seen plenty of sanding marks in my first big table project. I’m not sure if this is user error, either i was pushing down on the sander or I let it tilt and I etched these sanding lines in the face of my table.

I’m wondering, is there a better sander for me? Looking to remove high volume as well as sand up to finish, would a random orbital sander be more efficient than this model?

I ask because it seemed to take a long time to remove material on a rough piece of board I bought, as well I don’t ever want to see sanding marks!

Thanks in advance guys

The 505 is not really intended (or practical) for “high volume” removal. It’s a finish sander.

A random-orbit sander will remove material faster, a belt-sander faster yet.

Keep the 505 for the final stages, and use a light touch, with the grain, to avoid sanding marks. Also be sure to work your way through the grits, and clean the residue off when changing grits.
