Im about to convert an old Whites of Paisley machine to metal cutting,where can i get a metal blade,if I can get the blade by the foot?I can tig weld it to the correct size.

If it's a wood cutting saw it will be too fast for metal unless you have an inverter & 3 phase motor on it, but it's not worth the expense of fitting one if not,you can buy bandsaw blade in 100ft coils, I've been making mine for yrs,I scarf the joints & put them in a home made jig & silver solder them together, you can get a proper blade welder that welds & anneals & grinds the sides,
but again it's the cost,I ''dropped across'' a wadkin bursgreen bandsaw blade brazer but whilst its convenient it's no better than my home made jig & propane torch, I buy my blade from cromwell tools.
slan go fol
Thanks,Ill try cromwells,I used to have their catalouge.Yes,its a 3phase machine,Im going to fit a single phase motor (the current motor is tha size of an A series leyland engine lol.Ill pulley it down if needs be to a suitable speed.Yes,scarf joints should be perfect as long as its ground smooth id think,its what i had in mind for buying it in a continuious coil,only use my tig thinking it would be a stronger weld.Thanks for your help.
I didn't have much luck tig welding blades, but I bought a roll of 24tpi blade that's something like 3/16 wide! I scarfed the ends and tig brazed them and it worked. But 2800ftmin is way to fast, the saw cuts ali lovely with a wood blade at that speed.
Tpi depends on the thickness of material you are likely to be cutting. Ideally you want at last three teeth in contact with the metal at any one time, so 3mm steel would requires at least 25tpi.
For mild steel you want a bi-metal blade.
A wider blade will tend to cut straighter, a narrower one is better for curves (on a vertical saw). Also be aware that curve cutting will tend to put a set on the teeth which will tend to make the blade wander on straight cuts. SO it's worth getting one of each if you want to do both straight and profile cutting.
