Hi, are there any plans on how to make a woodworking vise? I want to attach it to an Irwin Work Bench.

Just a normal drill bit.

What’s the best way to countersink screws? I generally go too far or too shallow or the countersunk hole is crooked and part of the screw sticks out. ...

Hi. I have just bought an Ozito 12v cordless drill. Could I use the battery from that in an Ozito 18v Circular saw or other Ozito power tool.
