Thread: Bandsaw tension spring

If you are working in isolation, as it seems you are, I'd recommend going to the library and borrowing some of the current crop of bandsaw books - this is a starting point - most of them have tables of 'suggested' tensions for the various widths/thicknesses of bandsaw blades, usually expressed as 'pounds per square inch' as they are Yank books. You should also have a word to whoever you will be using to make up your blades - unlike a 14" saw, you probably won't find many off the shelf blades at the corner hardware store - they may give you different tensions. Then, armed with all this knowledge, go to the spring manufactures & give him the details - round or square cross section, spring maximum diameter, maximum uncompressed length, minimum compressed length, tension required and see what he can do.

If the saw has a brand name, you could try some of the Yank forums - such as Knot's Landing run by Taunton, the FWW people. There are a heap of old tool junkies, and as there are 10x more Yanks than Ozzies, you have about 10 times the chance of finding someone who either knows the original answer or has done it the hard way.
