I have an older sears model 113.244400 10 in. Band Saw that calls for 1/4 or 3/8 wide X 72 5/8 In. long blades.That 72 5/8 inch length seems to be an odd size when I look in catalogs I see 72 or 73 1/2 lengths and am wondering if any one has been able to use one a bit shorter or longer other than the sears brand? Also could I use a 1/2 inch wide blade in it the manual calls for either 1/4 or 3/8 wide.TIA for any advise.
