Agree. More pictures needed. Is it me or is the first picture the same picture as in popular mechanics?We need more pictures to better determine what all it does do, that one hand wheel has me baffled! it may very well be to put the set in a saw, but it also looks like it can strech / shrink something with the other hand wheel.
Yes Dalgirl .... humping the cams WILL lift the bars ... on the cam side of the pivot bolts. The end of the bars on the other side of the pivot bolts will pinch ... presumably a band saw blade.Looking at the 2 levers it would seem that if you pushed those down the cam would lift the bars, so I'm having a hard time seeing clamp bandsaw blades? The base looks like a shoe cobblers form pedestal.
If there was a pivot in the center of those arms I could see it working that way, but it looks like a bolt on one end and cam on other. Seems like cam would tweek the bolts? Agreed, we need more pics, and after 5 years you would think someone could have cleaned it up and gotten the parts moving, which might give us more cluesYes Dalgirl .... humping the cams WILL lift the bars ... on the cam side of the pivot bolts. The end of the bars on the other side of the pivot bolts will pinch ... presumably & band saw blade.
