Clamping up four mitered corners is tricky. You can buy specialty clamps for this, but I make my own. Here’s how to do it. Start with a long 1×4, as it’s easier (and safer) to clamp for making the angled cuts than a short piece. Mark out the blocks, and then drill a 1-in. diameter hole in the center of each one. The hole prevents the blocks from getting glued to your project. Cut 45-degree angles tangent to the hole, and then cut the blocks free from the long board. We’ll walk you through how to make one for your home shop.
As soon as I came across this tutorial, I didn’t wait any longer to start building one. Some of the items you need for this project are hardwood plywood, saw, glue, nails, drilling machine, etc. The video is very easy to follow for anyone with basic woodworking knowledge and experience. The first source link also includes a step by step procedure in plain English for those, who are not comfortable enough with the video tutorial.
Here’s a nifty tip—with a nifty tip—from faithful reader Don Ayers: Fill snap-capped sports water bottles with glue and stick them upside down in a hunk of 2×6. Now you don’t have to wait for the glue to run into the neck of the bottle, and the cap will control glue flow (and never get lost!). To holster the glue dispensers, cut holes in the base with a spade bit that’s a smidgen larger than the cap’s diameter.
