I have an older table top bandsaw that I have used for some time.Â* I

With the metal cutting blade every thing was fine, but when I switched
the wood cutting blade would not cut.Â*Â* It is almost like pushing the
wood into a wall.

I have check every thing I could think of ie teeth directions,
tension, etc.Â* I have checked the height of the blade guide to insure
that there is clearance for the wood to pass under it.Â*Â* I have
purchased a new blade but not installed it yet thinking the that may
be the problem.

Is there any thing else I should be considering that would cause the
saw not to cut?

I assume that you can get the workpiece in contact with the wood.
What happens when the teeth contact the wood?Â* Do they continue to "cut"
or do they stall out and stop.

Obviously, if they continue to move against the wood but do not cut,
you're mistaken and are trying to cut a piece of carbide steel rather
than wood.

OTOH, if the blade is stalling out, something in the drive train is
amiss:Â* tension, drive belt slipping, tires on the saw slipping?

If you ARE at least scoring the workpiece with the bandsaw with the
existing wood blade, go ahead in install and tension the new blade.Â* The
old blade may be ruined and you forgot about it or the previous owner
(if there was one) did it and you just don't know of the particular
problem.

Keep us all posted.Â* It's an interesting problem.

I have several small pieces that are left overs from a picture frame.
When I start cutting from the pointed end of the miter, the saw cuts
into the wood it reaches a point and then will go no further. The blade
seems to be moving.

How far into the wood does it cut? If it only goes a couple of inches,
then maybe...

In your OP you said "It is almost like pushing the wood into a wall."

On my bandsaw there is an insert plate around the blade. That plate is not
perfectly flush with the bandsaw table. It is below the table by about a 32nd.

Sometimes the wood, especially small pieces, gets caught on that little lip
and stops - like it's hitting a wall - once the end is about 2" past the
blade. I have to lift the wood slightly to raise it over the lip and move
it forward.

Just a thought.




This weekend, I will install the new blade and see if that corrects the
problem
