I have a Grizzly G0555 with a 12" riser. Added an Iturra spring.

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,

12" riser? not 6"

anyway, a 1/8 blade is a touchy blade. I use a carter guide for scrolling.
This is not a blade that you use for long straight cuts, it needs support
and it needs the guides setup perfectly if you are using guides. I don't
use guides with the 1/8, just the single thrust bearing behind the blade
which has a groove in it...

If you are talking tracking on the wheel itself, well that's a result of a
tuned saw. you must have a coplanar set of wheels, you must have a crowned
wheel, and you must set the guides correctly as above. Coplanar is the
most important 1st step.

Yes - 6".

I am using the Carter guide. The cut quality is fine - just that the blade
will come off the crown of the wheel and move rapidly forward or back. I can
check again but the wheels are coplanar. I've used 3/16, 1/4, 1/2 blades
with no problem with tracking - just this 1/8" that's giving me fits. I'll
take it off and rechec the wheels and then reinstall. Perhaps I didn't get
it right on the crown of both top/bottom wheels.
