Confused about staining/finishing on my project
I am working on making a very simple replacement table top for an antique sewing machine. I have used boiled linseed oil for previous projects because a friend who happens to be a woodworking professional told me that it was a really great finish for most woods. I am now attempting to determine my next steps with this table project, and after I char the grain with my torch I wanted to rub some linseed oil in. Problem is, I started reading online that BLO isn't really protective at all. I also read about pre-staining, which is an entirely new concept to me and just adds more confusion to the mix. When I rub BLO into my wood (which is pine, and I believe treated pine at that), what am I really doing? Just adding some color right? If I want to use this stuff on my table top, and have some form of protection, what materials do I really need to be able to do this? The wood has already been orbital sanded to a 220 grit, which I believe is pretty typical.
