I have a small Chester H110 metal cutting band saw which periodically decides to cut less square than I would like. When I first bought it, it cut decidely squint, but the cause was obiously work shifting in the "rapid action" vice and Chester duly replaced it with one which works properly.
The user guide is not too helpful on this point, it says "unplug machine, loosen nuts, adjust, tighten nut, reconnect power" but gives no idea what "adjust" should involve.
On dismantling I found the boss on one of the band pulleys was still rough from the casting and this was binding, but this was rectified in the lathe.
Now it cuts pretty square; at least well enough to cut bar section to face off in the lathe, but having used other metal cutting band saws I think it could be better. Does anyone know of a book/article on adjusting/improving these machines? I'm quite happy to make modifications to the machine if they will make it work better.
