That is A LOT of heat and pressure!! Slow down a bit and take your time! Scroll saws were not meant to cut 1/4"  steel plate.

Holy crap!  I thought *I* probably used my blades too long but I am just a minor leaguer compared to you!

These blades were each used for six, yes six, cuts - each cut was approximately 1 1/2 inches long, and the cuts were made at a normal speed and pressure (at least until the last bit of the last cut). 

I was cutting the sandpaper I was provided by Judy, and using a set of wood blocks as guides.  The wood guides are still in good shape.  The paper is 180 grit and used for the manufacture (in this case) of a sanding mop.

The first set of cuts went well until about the middle of the fifth cut, then I had to start pushing a bit, of course by then I was obviously losing some teeth (on the blade).  The last cut required a goodly amount of pressure - but it was not until I was complete with the sixth cut and pulled the project out that I saw the results.

I will say the blades held up, and the toothless area is actually fairly sharp, thus making the pushing through possible.

It was an interesting cutting experience to say the least.  I must also state these blades were pinned blades at one time and I have no idea as to their age.

I am guessing the comments will continue - but now you know some more of the saga.

Stay well and have a decent day.

Hi Judy,

I think even hacksaw blades would suffer greatly trying to cut sandpaper, and yup - the spiral blades would really have a tough day at it.

Oh well, I guess we all live and learn, some of us more than others  :D .

What about running it through a band saw at a slow pace with pretty good aggressive blade?

Just curious, what size blades are those?

I figured sandpaper would be tough on blades but that is some *spectacular* wear!

Morning folks,

I again tend to believe even a band saw at low speed is going to suffer when cutting sandpaper, after all the purpose of the sandpaper is to remove material.  I personally would rather use up a few scroll saw blades as opposed to even one blade for my band saw.

I am not sure of the size of the blades used for this job, I know they are the largest ones I have in my shop.  If someone is really curious, I can measure them, but I would tend to believe they are in the size 9 area.

Hope your day goes well.
