Thank you, Benvenuto!
For those wishing to get their linseed oil varnishes to dry, and you lack sunlight (a requirement), what do you do? Well, you need the UV light that is in sunlight.
I set up some Blacklights to see if that would work on my "period correct" linseed oil varnish. Well, it does work, but very, very slowly. Benvenuto mentioned that halogen bulbs put out UV-B (the light that gives you a suntan). The Halogen bulb packages all say to not use the bulb without the UV filter glass... :hmm:
Well, I bought myself an $11 halogen work light with a 500 watt bulb (gadzooks! there's actually recoil when you turn them suckers on! Some radio stations don't put out as much power!). I also bought a 300w bulb to put in it. I set it up in front of my stock, which is in front of my high-tech scrap wood board and aluminum foil reflector and turned 'er on. I am moving the light higher and lower every hour to put light on different areas of the stock, and to prevent overheating. IT WORKS. In the last few hours, it has dried more than it has in the last few days, even when setting the stock out in the sun. (The highs here over the last week or so have only barely gotten above freezing. I had already been told that down to about 40 degrees it was worthwhile to put the stock out in the sun, but below that, you had just as well keep it inside). It's like a warm, sunny day inside my shop!
Just don't look at the light, and keep your exposure to a minimum. I'm only in there long enough to check the varnish and move the light.
