Compressing or putting tension in the inner part allows it to grow along with the rim and all is well. Simply put, in a spinning saw blade, the heat of cutting and centrifugal force cause the outer part to want to grow. Leveling seems obvious but what tension is and does for a saw can get a little confusing. Much can be done with rollers, and there are new automatic machines in use, but traditional sawfilers still use hammers & anvil along with straight edges, possibly a tension gauge (that looks like a slightly curved straightedge), and a good eye to massage a saw blade into good form. This explains the great difficulty in getting all this iron into the back of my tired old Cherokee.Ī saw makers anvil of some kind would have been used in manufacturing a new blade before initial use but most of these anvils would be found closer to the sawmill I think.īesides sharpening, routine maintenance on either a band or circular saw requires tensioning & leveling to keep them cutting straight. I would make it 300lbs as a conservative estimate considering the width at the base is a full 12x15. A 12x12圆 = 1/2 cubic foot so for start this anvil is well over 250 pounds. I am pretty much taking for granted no new guys are getting into the saw blade business.īased on the above link: iron weight 419lbs per cubic foot. What I would like to hear is any sense of where these stand as desirable for collecting or more just an oddity these days. The stand is welded with a curious feature being the log. Does anyone know the weight?Īre fisher catalog reprints available? Or available as a PDF online download? This one has 6x12 face, 12x15 base and 12 inch tall. It has cast in the anvil the name "Fisher", the eagle and a date of 1906. I found a pic in my Anvil book that confirm that and called it a Saw makers anvil listed under Fisher Norris. The seller though it was for tuning circular saw blades. I just took this home and like to learn more about it.
