Pictured is a “New England Band Saw” by Collins & Greenwood of Lebanon New Hampshire which came out of a shop in Marlborough New Hampshire. Coincidentally I had submitted an engraved advertisement of this very machine about a year ago making this find all the more interesting. There are patches of rust but much pin striping and freehand flourishing remain. A table, guides, guide rod with acorn finial, and new tires are needed to get her up and running. The C shaped frame is a single casting with separate legs and the nine spoke wheels are cast iron as well. There is some flex to the frame on this model but an extra tab with bolt hole at the frames top may be designed to secure a brace to the ceiling which should go a long way to deaden vibration and horizontal flex.

What has me absolutely perplexed is the fact that as the top wheel spins it tends to grab the retaining nut which tightens and seizes the top wheel to the frame. Were this to happen while operating at speed the delicate cast iron spokes would certainly shatter with catastrophic consequences. How this machine operated for years let alone one hour without seizing is beyond me. I could taper pin or cotter pin the retention nut to the shaft to prevent it from over tightening but this would be both unoriginal and make it difficult to take up play as the bearings wear. Any ideas?
