Assuming that you’re using one of their more organic oils, Tried and True is a little too organic, which slows up the dry time. Some very good suggestions on here, I’d only recommend that if the time between coats is too long you add some Japan solvent to your next coat, not much is needed or Milkpaint sells a pretty good citrus solvent that cuts down drying times on organic oils. Someone mentioned using an artists solvent in the finish, this would work very well too. The main issue with organic oils (walnut oil, oil finish, danish oil) is they tend to be more purposeful for food safe products, like salad bowls, canteens and spoons. Tried and True Varnish is not bad, but also will take long to dry if the weather conditions are not ideal.
When I apply oils its usually as a top coat after I varnish, and i use extremely small amounts. I rub on the oils (linspeed linseed oil) with a magic eraser, which acts as a type of buffing pad, my stocks dry well in about a day or two in most conditions. I recently did one in damp conditions here in NJ. Dried in 2 days.
