agab6601 Posted April 5, 2011 Report Share Posted April 5, 2011 I know this is a very elementary thing, however I have fiddle farted around with this for a while and I was wanting to know if anyone has any good designs for sanding blocks? I have made a couple (poorly) enough to get by on the task at hand but that is usally as far as they go. I primarly sand when I have a refinishing project, I have used card scarpers normally if I am trying to build something (which I still need pratice honing the burr)but ultimitley I need to sand since the grain is raised and well it is just what need to be done. So any designs or thoughts on this would be great. I know I could just buy them but that's no fun! -Andy Quote Link to comment Share on other sites More sharing options...
Dave H Posted April 5, 2011 Report Share Posted April 5, 2011 i use belt sanding belts and use yellow glue and glue them to a piece of wood the same width as the belt i get about three 7" blocks out of one belt i put glue on a block add the belt glue another block add the belt put the belt faces together and clamp they last a very long time. i also have peal and stick rolls of sand paper and i just stick that to a block if i want a lower grit. my belt blocks are 80 grit and 100 grit.

konkers Posted April 5, 2011 Report Share Posted April 5, 2011 Take a look at the William Ng scraper sharpening video. At ~2:00 he pulls a sanding block off the wall... It looks like it's just a block of wood with a dado cut along one side. Both ends of the sandpaper fit in the dado then a 1/4" strip is placed in the dado to hold the sandpaper down. Looks like a nice simple design. I'm planning building a handful myself. Quote Link to comment Share on other sites More sharing options...
petersb Posted April 6, 2011 Report Share Posted April 6, 2011 I like these. I haven't made any yet. http://www.thebespokewoodworker.com/blog/2009/06/29/sanding-blocks/ here are some other pictures to help get the creative juices flowing. http://www.google.com/search?q=homemade+sanding+block+photos&hl=en&rls=com.microsoft:en-us:IE-SearchBox&prmd=ivns&tbm=isch&tbo=u&source=univ&sa=X&ei=huqbTeTKM4q8sQPM14CPBA&ved=0CB4QsAQ&biw=1579&bih=731 Quote Link to comment Share on other sites More sharing options...

konkers Posted May 11, 2011 Report Share Posted May 11, 2011 Was going to make some myself. Do you think the strip in the dado is tapered? I'm guessing it's just a dado. The friction of the sandpaper should be enough to hold the strip in. Quote Link to comment Share on other sites More sharing options...
rmason Posted May 20, 2011 Report Share Posted May 20, 2011 I don't use anything fancy just a block of scrap MDF cut to 4.5" and use pressure sensitive adhesive backed sand paper and I am good to go. PSA paper is also very handy to make small custom sanding blocks for getting into tight areas. I don't know how I lived with out it. Quote Link to comment Share on other sites More sharing options...

Mmetz23 Posted September 12, 2011 Report Share Posted September 12, 2011 I finally ened up making some of these tonight and wrote up a quick blog post about them. Here's some pictures of the process. I made the same ones as konkers. (Thanks konkers for the insight on dimensions) The only difference is my dado is a little shorter. I think i only went a half inch. Mostly because i forgot what konkers did by the time i was in the shop. After i made mine i went back and checked out he video again and noticed William Ng's strip has a curve along the bottom edge and also extends past the edge of the block. I'm guessing the curve helps eliminate a little friction with the paper in the dado. I noticed on the coarser grit that there is a lot of friction in there and in one case i couldn't push the strip all the way to the bottom of the dado. Not really a big deal though. I think extending the strip past the block may be a good idea to be able to remove it easier but again flush with the block doesn't seem to be a problem either. Next time i might try the curve and extending the strip... I made a quick blog post on this as well. Another thing i didn't notice initially is that one of the guys in the class takes a picture of it. He must have had the same thought as us.

I too have thought of building a bunch. Haven't gotten around to it. Thanks for the insight SDWoodworker. I ended up adding some cork to mine based on your insight. I found a 1/25" cork roll from hobby lobby. It had adhesive on it and i was easily able to add it to my sanding blocks. It definitely helps soften things up a bit. Here is my blog post about it with some additional pictures. Quote Link to comment Share on other sites More sharing options...
Jerry_in_SD Posted September 16, 2011 Report Share Posted September 16, 2011 Now you have inspired me to make up a bunch. Nice to have one for 80, 100, 120, 150, 180, 220, 320, 400 grits just ready to go... Quote Link to comment Share on other sites More sharing options...

I'll probably only apply to one of the faces so that one can be kept for sanding surfaces flat. Quote Link to comment Share on other sites More sharing options...
Jerry_in_SD Posted September 22, 2011 Report Share Posted September 22, 2011 I just finished making a bunch (maybe a dozen or so). My hold in stick is tapered. I tilted the saw blade 3 degrees on one cut. I also added the rounded end like William had. Picked up the same cork roll (but from Michael's) which is peel and stick. Thanks for the inspiration to do what I have wanted to do for some time but never got off by butt to do it. Quote Link to comment Share on other sites More sharing options...
TimV Posted September 23, 2011 Report Share Posted September 23, 2011 Wow, SDW, you outdid me. I only made 4 last night real quick. A couple of changes I made. I already have a purchased block. I wanted to be able to rip the sandpaper to the same dimension for both the purchased block and these new ones. That made the length shorter, closer to almost square @ 3-1/2". I also used an old mouse pad instead of cork. I cut the mouse pad to fit, flipped it over and used spray adhesive to adhere it to the block. I like having these ready to go when I need a different grit. Quote Link to comment Share on other sites More sharing options...
AceHoleInOne Posted September 29, 2011 Report Share Posted September 29, 2011 I buy the 2 1/2" roll's of PSA 80 up to 180 grit. Simply stick to any size scrap piece of wood. Makes for great custom sanding blocks/sticks. Can even stick some 80 grit on the top portion of a long thin stick...makes for a nice file. The cork added to a block of wood is the way to go for wet or dry sanding topcoats. A good idea is to round the bottom edges of your sanding block, just a bit. So when you come to an edge, your not rounding them over or goofing up a profile. Especially important when block sanding a finish. That's just my opinion, I'm sure there are others. -Ace- Quote Link to comment Share on other sites More sharing options...
jmaichel Posted September 30, 2011 Report Share Posted September 30, 2011 I have not bought any yet but when I do I am going to get these sanding blocks. James Quote Link to comment Share on other sites More sharing options...
