I've heard PatB say he's used pine varnish, can someone explain this to me please?

Gary, I dissolve hard, brittle pine pitch in denatured alcohol to make the varnish. Then just brush it on. When the alcohol flashes off(evaporates) the shaft is coated with a thin layer of pitch. I also use this to seal sinew wraps on arrows.
 If your pitch is not hard and brittle the varnish will be sticky when applied.

I have a little hard pitch but to make sure before I make a batch is there a recommended way to speed up the drying of some softer pitch?
Thanx PatB,
Gary

Softer pitch has to be cooked to burn off the turps. If not, they will naturally dissipate but it takes a long time.

PatB you say dissolve it in denatured alcohol, why not isopropyl, its just to melt it down and then evaporate anyway right?

Denatured, Isopropyl, moonshine, your favorite liquor, probably acetone or any volatile solvent that is compatible with the pitch will work. I keep a can of denatured alcohol handy so that is what I used.

your favorite liquor

Now that's just wasteful. I'll use isopropyl, it's horrible over ice anyway, and a little cheaper.

I used Acetone, seemed to work ok.
