Sanding Blocks

NEW SANDING BLOCKS!!!

That’s right folks, a post that only those that work on guitars could appreciate. You’re welcome.

For years I’ve been using a combination of a basic 3M sanding block and a small art gum eraser.

To be honest I barely used the larger 3M block, usually for dry sanding during prep with lower grits. When it came to all the rigorous wet sanding, I would primarily use the art gum eraser, for years! Recently, after noticing my small eraser starting to fall apart, I finally wised up and realized maybe there was something better I could be using that might speed up the process. It takes a long time to cover a guitar front and back with a thing the size of a 9V battery. It’s still handy when I need to just focus on a small area, and it has a bit of flex which comes in handy going around the curves and sides.

My brother built a CNC machine from scratch this past year and always has handy materials around, so I thought to ask him for some acrylic. He had a small piece of scrap that would be perfect, 1/2″ thick, 2″ x 5″. So he cut it into a couple pieces for me. I thought it would be nice to have a couple options, so he cut a 2″ x 2″ square and a slightly larger 2″ x 3″. The picture on the left shows the pieces as he gave them to me. I just took the palm sander to the edges, rounding them out and flattening the sides, giving them a more “finished” look, as seen on the right.

These work marvelously. With a perfectly flat, hard surface, not too big, not too small, I feel like I’m getting a much better use of my energy, time, and sand paper. Super easy to clean and dry. And it covers the surface area of the guitar really well. I find I lean towards the 2″ x 2″ one more often, just more versatile I think.

 

 

 

 

 

 

 

 

 

I still use the old blocks, but it’s great to have a combination of sizes and materials to choose from now.
