What a beast of a machine! Looks like it would be great if you had hundreds or thousands of feet of Moulding to make or a small sawmill to feed it. Put a shaper to shame in a throughput and chip accumulation. I wonder if they ran 6" cutterheads on the 4" exposed spindle shafts leaving the outer edges extending past? I would expect tooling up for complex moldings would be a fair expenditure.
Hopefully it's a good bit faster than the shapers or williams and hussey I've been using. For any long runs I'm planning on hooking up two blowers and just blowing the chips into a pile outside.
looks like it was crashed at some point, tipped over for sure, but likely threw a knife and bent the spindle or spindles. I can't see any other reason for cutting the heads and the spindles to 4.5". The way the heads are secured you can only run a smaller (or same length) head as the spindle length.
Tooling isn't horrible (beyond the head costs). S4s heads are the cheapest.
