Pine pitch waterproofing/sealing sinew

[shackleton]

 I purchased some pine pitch and I was wondering how I could use this to seal/waterproof sinew wrap on fletching?My 1st build.

I've never tried it yet but I think Pat B disolves dry hard pine pitch in denatured alcohol then strains it and stores it in sealed container. You use it like varnish brush it on alcohol evaporates leaving pitch to seal your project.

Maybe Pat will chime in here

That's exactly how I make pitch varnish. I not only use it to seal the sinew wraps but also the shaft sometimes.
 Scott, is the pine pitch a commercial product?  What is it's intended use?

Very cool way to do it! I usually use tb3 but pine pitch is plenty here in the evergreen state. Thanks for bringing this up!

Enlighten me, refresh me or just wallop me along side the head to jar my memory -  pine sap, I know, pick it off the trees, but what are the differences between pine tar, pine pitch, and brewer's pitch( which I got)?  I have used pine tar, turpentine, and linseed oil, equal parts, to make a varnish.  I used it on my lodge poles, but got it on the wooden canoe site

I've never used anything but hard, brittle pitch I found on pine trees. If it was not hard I had to cook out the turps to make it so.
 If what you use becomes hard and not sticky when it dries then it should work fine.

Pine pitch is usually sap, charcoal, and I’ve used beeswax and rabbit poop and other fixes into it. You’re saying straight sap and alcohol?

Tracker this isn't pitch glue we're making. This is a way of sealing like varnish. You use the same pine pitch but the hard dried up stuff. You dissolve it in denatured alcohol and strain it to clean it up. You have to store it in a sealed container. When you brush it on something like arrow or sinew the alcohol evaporates leaving a thin film of pine pitch to seal the water out. At least that's how I understand it.

Pat
I sent you a private message.  I have a few different things for you to play with if you are interested (different types of hotmelts that act very similar to pitch.  I'd send it to you if you wanted to play around with the different products.
