Thanks again for the replies, I don't have any BLO but I tried some Chambers, Wahkon Bay and Behrs Tung Oil on a slab from the side of the blank. The chambers left it unchanged which surprised me because it has a brown color to it. The Wahkon and the Tung both darkened it considerably, the second coats of each remained the same, maybe the tung oil got a little darker. I'll get some BLO from the art supply store this weekend.
I appreciate all the suggestions to use lye or a similar chemical, but I'm steadfast and stubborn to leave it natural. I just don't care for the red color lye gives you.
Thanks,
Bill
It takes time for it to darken. Put it in the sun with no window to act as a filter.
The stock on the rifle above changed hardly at all when the oil was put on and it was pretty dark oil. In a week or 2 the color was much better.
Art store BLO is as purchased and must be head modified and bodied to make a good finish. Stand oil is made is different manner that stock finish and will not perform the same.
If you want good oil you have to make it or get it from someone who does.
I liked Parks BLO from the lumberyard till they switched brands. The stuff they sell now is darker to begin with and seems to make OK finish.
This is the base oil, as bought its paint thinner not stock finish. You need to heat it with some limestone or other calcium carbonate to neutralize the acids and a little Japan Drier to help the drying a little, tablespoon to the gallon is plenty less will likely work OK. Once heated high enough to smoke for 1/2 hour or so its good to go for a light oil when cooled.
I think in a few days you will find the Chambers oil will darken the wood satisfactorily.
The top 2 photos are a few months apart and predate the last photo by over a year.
But different cameras, different light etc etc.
