Most woodworkers have some type of foam board laying around the shop. After insulating my shop walls with 4" thick ridged foam board, I was left with pile of cut-offs. Not one to throw anything away, after a while I found it useful in a variety of ways. Try some of these tips. If you have one of your own and would like to add it to my list, I'd be glad to hear from you!
Tip #1. Riser blocks. Use under items stored in the basement or workshop to keep them off the floor and away from water and moisture.
Tip #2. Glue blocks. Cut small squares to put under glue-ups to keep them up off the bench and from sticking to the benchtop.
Tip #2A. Painting/gluing Pyramids. Don't waste your money on buying those expensive painting pyramids and make your own! Use this handy jig to cut up scraps of foarm board and keep some on hand.
Tip #3. Clamping Blocks. Cut pieces the same size as your wood clamps to protect your work.
Tip #4. Bulletin board. Use a large piece and screw it to the wall to use to pin up notes.
Tip #5. Pen tube glue inserts/plugs. If you are a woodturner and make pens, there's nothing more frustrating than having the ends of the brass tubes get glued shut from polyurethane (foaming) glues. To avoid this issue, use different sized plug cutters and cutout plugs to fit the ends of the tubes before gluing them into the blanks. I drill out a box full of 1/2" and 3/8" plugs at a time.
Tip #6. Ear Plugs. After discovering tip #5 when I used a pair of those little yellow ear plugs for the pen tube inserts, and then using the foamboard, , I also found the form board works just as good for ear plugs.
Tip #7. Back-saver mats. Use larger pieces of the thinner 1" thick form board and cut up mat size peices and place them in front of your workbench. If you can't afford the hook together mats, you could also place it underneath your wood or carpeted shop floor.
Tip #8. Tool Trays. Use pieces of foam board to store your hand tools. Cut-out a section in the board the shape of the tool for a nice little storage tray (And if you're forgetful like me - it will help you remember where the tool goes!).
Tip #9. Parts Mockups. Use form board instead of your expensive wood for mockups. You can use this for making anything you'd make from wood. Works great for figuring out proportions before going to wood.
Tip #10. Chair Cushions. Save your bottom! Cut out a piece and use it for a cushion on your hard-top bench stool.
