Instead of permanently mounting my 6-in. vise to a work-bench, I attached it to scrap plywood so I can clamp it wherever I need it. Stack two pieces of 3/4-in. plywood and screw them together with 1-1/4 in. drywall screws. Mark the vise-mounting holes on the plywood and drill 3/4-in. guide holes through both pieces. Recess the nut by drilling through the bottom sheet with a 1-in. spade bit using the 3/4-in. hole as a guide. Fasten the vise to the plywood with bolts sized to match the vise-mounting holes. If the bolt shafts are too long, cut them off with a hacksaw. — LuAnn Aiu. Plus: Learn how to use vise grips to pull nails.
This simple jig makes laying out circles a breeze. Drill a 1/8-in. hole through every inch mark on a ruler or yard-stick. To draw a circle, place a pin through the number “1” into the center of your board. Add 1 in. to the radius of the circle you wish to draw, and insert a pencil into this number. Using the pin as a pivot, rotate the pencil to mark the circle. — Edwin Constantino. How to Cut Curves in Wood
There are a few things particleboard is NOT. It’s not medium density fiberboard (MDF)—a material with greater density and weight composed of more uniform particles. It’s NOT oriented strand board (OSB), a material composed of large wood chips and strands that’s structurally equivalent to plywood. It does NOT have great nail or screw holding ability, nor is it all that water resistant; water can quickly cause the material to swell and lose structural integrity. But if you need something flat and cheap for use in a dry place, particleboard will do you proud. Learn how to make a plastic laminate tabletop with a particleboard substrate.
