Sanding advice

Looking for advice on how to best sand. I am using mdf and 1/4" plywood mostly. Cutting signs with a lot of tight corners. Bought a dremil but can’t find a good bit to get the tight spots well. Using sand paper which takes a long time. Just wondering if anyone has figured out how to sand quickly. Thanks!

wow - I like. Can see how that’s better than what I’m doing. thanks

For cleaning up my 2mm lightplywood parts I use sandpaper on a spunge grid 150, very fast and very smooth.

These work great (especially for vcarving). They are flexible and can get into the nooks and crannies.

I’ve been using these Proxxon products to do all my detailing…

Pensander PS13 & MICROMOT AC Adapter NG 5/E

Delta Sander OZI/E

On the Pensander PS13, I make my own sanding pads in various sandpaper grades using Scotch double stick tape laid out on the back of a sheet of sandpaper and simply cut the shapes I need for each adapter. Works like a charm. I like the variable speed control with the NG 5/E power supply

Same for the Delta sander, I buy larger hook and loop pads in various grades and cut out several pads to size.

The Pensander PS13 & NG 5/E were purchased through Home Depot online. The Delta Sander was through

thanks for all the great suggestions. I just figured out today if you slow the bit down and replace it with a new sharp one, it cuts much cleaner! duh-figuring this stuff out on the fly.
