I've come across a few references in the forum to cold combining oil varnish and I'm hoping to get a few more details on how this is done exactly. What I've gathered is that this is a way to produce a more lean varnish than is possible by cooking resin and oil together. The resin is ground to a powder, dissolved over the course of a few days in a jar with a solvent, filtered, then mixed with oil, all cold. Is that the gist of it? My current experiment is 20g of cooked down colophony mixed in a jar with roughly the same amount of turpentine. After a day, the colophony has mostly dissolved (there are still small bits throughout) but the mixture is very cloudy. Does cloudiness mean I need to keep adding turpentine until it clarifies? Will it clear up with time? What is a good ratio here? Once the oil is added, how long does it take to combine? I assume there will be no pilling stage. I'm aiming to achieve the 4:1 ratio noted in the Brandmair/Greiner Book. Any advice/guidance in filling in the blanks would be much appreciated. Thanks!

Tools For Working Wood is a rather nice and trusty source for Woodworking Tools and materials. On one of their blogs, they have been putting out PDFs of a wonderful old magazine full of ways that things have been made. Issue 110 of Work Magazine has an article with a listing and illustrations of tools the author, J.W. Briggs, considered appropriate for making violins. The instructions are perhaps a touch sparse but all in all it is a delightful article. Issue 114 of Work Magazine continues the article as does Issue 118. Issue 118 details his varnish recipe so it is of special interest.
