Best way to mill old barn lumber
So I snagged a handful of old American Chestnut barn timbers and boards (yeah, the barn was around 100 years old, build like a bomb shelter) with the intent of making a bed frame out of them.
I think I can do it, but I need y'all's advice on how to do it best and safely. My tools and shop are severely lacking, and there's not much I can do about that at the moment, but I'm not averse to using hand tools. I have a cheap tabletop Craftsman universal drive table saw (I'm very aware that it's not very good, but it was $40), a battery circular saw, and some hand planes (and some other stuff too, but those are the most relevant).
I'm in the process of making some sawbenches to put the table saw on, but I don't have a workbench, or even a shop space. I'm limited to moving my tools out on the (covered) back deck/patio.
My thinking is to make a straight edge jig with some hardboard and 1x2 and some holddowns, and getting my first straight edge that way, but with the table only being 20-some inches, and no easy way to make an extension table, I'm wondering if that's just asking for trouble.
The lumber is 2 12'x2"x6" timbers I have to cut at 6' because of a nail, and the other boards are a variety of 1"x10" to 1"x14" planks. The longest I'll have to rip will be the 7' stretchers. They're about 1.25"x8".
The other issue is that there are bits of rot here and there. I'd like to keep as much of the width of the boards as I can, so I don't know if I can patch of stabilize those areas, and when I would to that in the milling/building process.
Sorry for all the long questions, but I think this could be some gorgeous wood when done right.
