I know sand papers are not expensive but I was getting tired of wasting half of the sand paper every time I use my old sanding blocks. So I decided to make a few sanding blocks that will allow me to use my sand papers more efficiently. I made four of these blocks using some scrap oak pieces in my shop. These blocks allow me to use 1/4, 1/3, and 1/2 sheet of the sand paper.

For the block that uses half sheet (5 1/2”) I have to make the top block smaller to fit into my palm. I know some people use cork sheet for padding but I found some 1/8” foam sheet with adhesive backing for $0.79 per sheet at Hobby Lobby. Now I am ready to do some serious sanding:)

Thanks for looking.

Good idea on the sanding blocks, you will get a lot of use out them.

I just showed these to my daughter (9 years old) and she is ready to put some together. We are always looking for things to do together in the woodshop and this is a great project for us and they will be very useful when we are done.

Great idea!!

Someone asked me to post the dimensions of the blocks. Here it is. These dimensions are to maximize the use of each sheet of 11”x9” sanding paper.

I use a 3”X21” beltsander belt over a plywood or MDF block. Cut the block 3’’ wide and you’ll have to fine tune the length to fit the belt. Round over the ends and slide it into the belt. You’ll want the fit to be tight and put the splice on the belt on an end. You can make several for different grits and these things will last a LONG time. You can use a bigger belt but I prefer 3X21. We used these in the cabinet shops and they got a lot of use. I’m lost without it.

Simon, I don’t know if its just on my computer but the dimensions for the smaller block along the long side are all mixed together and really can’t be read. Perhaps move half the marks to the right side for clarity. Again much appreciated for taking the time to add them.

Pat, The dimensions for the smaller block along the long side:
Top block – 6 1/2”
Bottom sanding pad – 7” including one 1/4” strip at each end.

The 1/4” strips are 1/2” tall.
