I’ve had a kind of crappy blue plastic borg sanding block for some time, and I’ve been lazy and switched out the paper. I don’t use it too often, but its finally given up the ghost and won’t really stay closed any more. I decided to make myself some proper ones with a nice cork backing.

Here’s the original borg crappy one..

The one thing I do like about it is that it is sized such that you can quarter a regular sized sheet, and they fit the sanding block right.

I had a bunch of sheets for cork, because I made myself a small corkboard/takboard for veneer inlay layout purposes. I had some spare blocks of ash, left over from the bench, but I actually ended up making a sizing mistake and switched to maple.

I drilled a 1/4” hole, counterbored a larger hole, lined it with 5 minute epoxy. and a 1/4-20 nut into it.

2 small walls on either end, to help retain the sandpaper, were glued on. My leg vice made an excellent clamp. Note that the counterbored nut faces down!

Then I cut some rough pieces of 1/4” cork backing. (I found it at Staples.)

Plenty of glue, there’s a lot of surface area to grab on cork, and some bench holdfasts make good clamps.

Some over-sized ash blocks, fitted snugly in between the ends, will give me room to sculp something comfortable to hold.

Some bandsaw work, followed up with the oss/belt sander, and voila!

much much much better :)

I used to have something similar, but without the cork on the bottom, if you just use wood backing, it’ll give you a straight plane to register the sanding paper against (good to sand straight planes and surfaces).

I need to stop just wrapping sandpaper around the first wood block that I have that’s about the right size and make something like this. Nice job. Thanks for sharing the process.

This took me about 5 hours total. Keep in mind I also spent time waxing the bed of my jointer and tablesaw, as well as making a small drill bit rack.

So, about 4 hours of puttering about, less than an hour of actual work. Although I broke it up over saturday and sunday so I could let glue dry!

while these are very nice, they would take me much longer. I’m going to stick with my $5 rubber block for now, but maybe someday. If I knew mine would come out this well, maybe i’d try.
