Ok, I confess.  My first scroll saw was 30 years ago.  For some reason I always believed the saw cut on the up stroke. For 30 years I have been putting the blades in with the teeth facing up, and wondering why no one came up with a good hold down.  I really didn't like to use my scroll saw very much.  Imagine my surprise to read on the Forum that the teeth go down.  Thank you Forum, enjoying scrolling finally.

Haa haa 30 years I'd have thrown it out the window by then.[rofl] Ah well good news for you then.

Great story George! I have a lot of, ""I always thought you did it this way ..." moments too! We're always learning from forum members.

People some times do this with band saws.

I've also see table saw blades inserted backward.


You are not alone.

I have a scroll saw branded for one of the hardware stores in NZ, and have been using it for about 10 months with no problems.
It is suddenly starting to run off to the right and i’m Unable to find a reason.
Any one with an idea as to the problem.

did it start after a new pack of blades?

Justgoober72, it sounds like the blade. 

Some blades are made by "punching out" the teeth. These blades generally cut to the right due to the manufacturing process. Its not a fault, just the manufacturing process of these blades.
Generally the cheaper blades that are found in hardware stores etc are like this.
There are other blades out there that have ground teeth and are generally sharper and cut straighter. Although they still tend to cut to the right a bit, but not as much.

Pegas, Olson and Flying Dutchman all have "PGT" (Precision Ground Teeth) blades. 

When trying a new blade, I generally test it first on a bit of scrap wood to see how it tracks when cutting. 

Steve Good explains this very well in this video.

Could be exactly what Rod posted. Maybe try another new pack. Could be that the grind is just off in that pack.
