I have had no problems with except one.



I've been trying to use a 1/8" blade for some scroll work and I'm having a

helluva time keeping the blade tracking.



I get it set and it runs fine for a little while and then it will start to

move either forward or back. I've tried TimberWolf and Olsen and HIghland

Hardware 105" blades and it makes no difference.



I've tried putting it on the crest of the wheel, just in front or just

behind the crest. It just seems so touchy I figure there must be a better

way.



Any ideas?



Thanx,

Vic,

I think you've already gotten some good input from others. When I first read of your problem, I wondered if there was a practical limit to how small the blade could be for a certain radius of curvature of the wheel camber. Perhaps 1/8" is too small for the camber on that model of wheel. Still, I like the thermal expansion explanation better.

I have the same bandsaw with the same riser block. I have long suspected the stock spring (probably from reading this group)as being inadequate. I'd like to hear more about your experience with the Iturra spring.

Thanks,

Bill
