Hartville Tool has a couple products that I thought would be a good add to any toolbox.
First was the “bevel boss”. It’s a 3” x 12” steel rule that allows you to set angles with your bevel gauge to a .25 degree. The reverse side is a ruler. It’s selling for 34.
The other product that caught my eye was the “angle fix gauge”. You can measure your angles and then it will divide the angle and you can use it to help line up your saw. Seems like it would be handy for molding work. And, as it sells for 15.00, it won’t hit the pocketbook so hard.
