Important Safety Rules While Working with Delta Scroll Saw

If you want to keep your fingers and parts of your body intact, here are a few of the rules that you should stick to:

  • Lower Down Clamp – Lower down clamp as close to the wood as possible. This is to hold down your work and also prevents your fingers from slipping into the blades.
  • Proper outfit – Don’t wear loose clothing, remove jewelry and tie back any long hair. Wear safety glasses. There’s a reason why carpenters and people in the trade wear overalls.

I will always have a special place in my heart for woodworking. I have such fond memories working on projects with my parents on the weekends in the garage growing up. We built tables, shelves, a backyard shed, 10' base for a water slide into the pool, 2 story fort playhouse with a fire pole, and so much more. This woodworking blog allows me to write helpful articles so others can enjoy woodworking as much as we have.
