  • Blades for Plywood

    Hello everyone. Much enjoying the forums and learning from everyone and enjoying the patterns here on the site. I plan to submit some of my own when I learn how to make them. My question today is that I receive alot of large chucks of plywood at work for free. My question is what kind of blades should I be using. They are between 1 to 4 inches thick.
    Thanks for the help

    First you will find you cannot cut 4 inch thick material on a scroll saw, max is around 2 inches thick.
    2nd, Plywood you are getting from work is probably contract grade plywood & is not suitable for most scroll saw projects due to splintering and interior voids. Unless it is cabinet grade plywood and not laminates even cabinet grade plywoods may contain voids between the layers. When you read about plywoods we are using we use a fine grade of plywood typically baltic birch which has several layers without any voids.

    As for blades 1 inch thick will require a number 7 and may work better with a number 9 or even a 12 and be aware that the glues in plywood will dull your blades very quickly.

      Finally got my energy level up enough to drag the saw out and get started on thank you state magnets for for all of my critical care nurses and doctors. They truly became like family in those days.
      This is 24 of the first 34 I am doing. These are all cut from some 3/8" wood I had intended...

      I said in late winter I was going to make a sign for my son's wedding. Becky thought I was crazy for working on it so early, but considering my current health issues, I am glad I finished early.
      Knew nothing about making a sign, but knew I could cut, so I jumped in--blind to some of the challenges...
