Bi-metal Bandsaw Blades.
Hello all,
I have just purchased a BS5A bandsaw from H&F and would like some advice on blades. I am not any experienced bandsaw user, and the machine only comes with a carbon blade. I understand bi-metal blades are the way to go but again I have no experience with them.
The type of work I will be doing mainly consists of cutting 1020 steel around 1" solid round and square (model live steam locomotive), with the occasional larger cut.
My questions are:
Where is a good source for getting theses blades made?
How many TPI should I order?
Do I need evenly spaced teeth or variable pitch type blades?
I am hoping some of you more experienced metal workers out there can steer me in the right direction with this.
Thanks in advance,
Ned

Hi Ned,
When I purchased my S/H bandsaw it came with a 6/8 or a 8/12 multipich blade. A little too coarse for most of my anticipated use. I ened up buying a multipitch 10/14 M42 Bimetal blade from here:

But there are many sellers on ebay too.
It is a Roetgen brand (which meant nothing to me) but I can report that these bimetal blades are pretty good. While I don't use the machine EVERY day, I have used it quite a bit since I bought it and the blade really show no sign of blunting at this stage. I anticipate it will last me a number of years (assuming correct use and care). While for my machine it was not cheap at about $90 (3660x27mm) it will be a long time before I need to replace it.
WRT the pitch or TPI, I would certainly look at a multipitch blade. I have been looking for a blade selection guide put out by Roentgen but I can't find it! I think as a guide you should allow between 2 - 6 teeth in the material at any one time. Any less and you run the risk of damaging or breaking off teeth, any more and you will find that the swarf cloggs the cut and jams the saw. I find that my 10/14 works really well for materials of similar size to your intended use and slightly larger with care. I always use coolant though.
Good luck,
SimonGirl, I don't wanna know about your mild-mannered alter ego or anything like that." I mean, you tell me you're, uh, super-mega-ultra-lightning babe? That's all right with me. I'm good. I'm good.
