You got is scottr... pic 7 that says "rip on the radial arm saw". Pic shows me crosscutting. Although you "can" rip wood on radial arm saw by twisting the carriage/blade carrier sideways and feeding board along the fence like a tablesaw with inverted blade, its dangerous and real messy, and few people use it that way.
Don't know what a Ross mill is, so no didn't get my idea from that. I actually dreamed that contraption up from scratch. I had a lot of figured maple chunks that were only a few feet long, was slicing them up on my resaw bandsaw in shop, but messy and slow, and resaw only has 12" capacity, so designed that rig to do it quicker and easier with my ripsaw. But it can only do up to a 5 ft long log. I have plans to design a longer one, using steel angle iron for the carraige, that will allow me to resaw as thin as 1 1/2" thick planks, and up to 8 ft long log or board. It will also be mobile, with locking wheels so I can move it around easier. Have rough plans in head, just haven't put them on paper yet. It will be similar design, just fefined a bit and bigger.
