I’m building a drafting table that has some 3” wide x 3/4” thick(?) dovetails that it will slide up and down on, and also will use a clamp block that will be used to secure it in place once it’s at the right height. The clamp block is just a 3” piece of the female side of the dovetail that gets cut in half so you can tighten it and take up all the clearance in the dovetail, and thereby secure things.
Question is, what finish to use?
The clamps will likely be in place for a long time in one spot, so I worry about it becoming glued together after a while.
Not sure if poly behaves this way or not. I don’t want anything too slick or the clamp might not hold as good as it could so oil/wax finishes are probably out.
I was thinking some arm-r-seal, since I’m using it on the rest of the table.
Suggestions would be welcomed

Can’t be much help on the finish , but I remember Drafting Tables from High School Drafting class. Still prefer them to CAD Programs.

Satin Polycrylic (water based)?
It’s what I like to finish my jigs and shop furniture with.

Have your say...
