Why not look at Grainger or McMaster Carr?

They have a bunch of varied size rigid pulley type wheels for a fraction
of what you are looking at doing.


I would, but I'm in the UK. And we don't seem to have places that sell
general engineering stuff to the public (or for sane prices)..

Unless anybody knows different? (I'm near Gloucester if that helps)

I don't think a bike wheel will hold the tension you need to run a
bandsaw blade true.

Well I know a 12" kids bike wheel can hold my weight and I'm 200lbs, so
it's in the ballpark for 1/4" blades. As others have said though, the
bearings might not last too long...

No math to prove myself right or wrong, but it seems that putting weight on a
wheel and tire mounted on a bike is not the same force/pressure as putting a
steel band around 1/2 of it and tightening it until the blade "pings"?

Still sort of downward force, I guess, but different tension/angles?

Can you tell that I failed math?
