I have wanted to ask this question of everyone for the longest time but keep forgetting to do it.
Well the reason keeps coming to me when i use my bandsaw.
No i aint broken a blade yet since i got her.
But way back when i first encountered a bandsaw i did nothing but break blades.
My Dad had a all in one Emco Star. It was kinda like the Sears mini bandsaw and a bunch of other mini machines all rolled up into one. Fantastic design when i think of it today dont quiet know what happened to the company. It came from Austria i think. Here is a picture i copied off another site showing what it looked like.
Here is a video of the unit.
Well i was let loose on Dads toy without any instruction we all worry about today. I dunno maybe he was not bright enough to see the possible injuries we all see at every step today or maybe he just had more faith in his son to keep all his digits and he probably felt if i loose a digit it would be through my own stupidity not his or the saw manufacturers.
Back in those days i made all sorts of things. Specifically toys. But i needed to make enough to kit all my friends out with the same toy.
So i was forever cutting any material Dad had in the shop. Not metal but wood and occassionally acrylic.
I think i broke a blade a month. I got blasted but they got repaired or replaced and life continued.
Back in those days neither of us understood thrust bearings or guide blocks or getting the blade tracking.
So i was wondering given what many of us have learnt about size of blade versus curve we wish to cut and guide block settings etc
Who has broken a blade nowadays and was their a reason other than say poor weld as to why?
Time to confess to those silly things we should not do.
