  • Excalibur 21 repair #2

    I just finished rebuilding my friends 2nd EX 21, This one was in much better shape than the first. No rusty bearings this time but I re-greased them anyway.
    I adjusted the front back motion and and the blade is also at 90 degrees to the table when using the locating pin.

    I used it a bit without a foot pedal. How anyone can do scroll work without a foot pedal is beyond me. What a time consuming pain to have to reach up for the switch every time you go to a new hole.

    Foot pedals are a must to keep hands safer for a quick stop! So where exactly are the bearings you're greasing? I just assumed that sealed bearing had to simply be replaced when the grease inside them lost their viscosity. Educate me please because I would like to prolong the life of my equipment with a few cents worth of grease! Thank you Rolf.

      You have to dismantle the saw to do it. The first saw I did for her was older and it broke an adjuster in the upper arm. Part #64 was originally 2 pieces with an adjuster in it. That part was notorious for snapping. It now looks like the drawing. Also in that saw both bearings in the Pitman arm part #10 were rusty. I was amazed that it was running at all. She ordered the replacement part and it came as an assembly. If you replace the original clamps with the Pegas version. the small bearings in the ends of the front arms parts 27 and 35 are reused. Since I had to take the saw apart anyway I greased every bearing in it. I will get a picture later of the assembly that she bought. It is like the first image but without the clamps and front assemblys.

        Not knowing any better I started without a foot pedal. Yes I sometimes do demo's without one but for all my regular scroll saw work I won't scroll without it.

        P.S. I also use a tall stool.

            Me too Scott. A barstool! I don’t know how people can stand and scroll at the same time.

              Dan, your questions are a little tough to answer without knowing a little more about this puzzle you're cutting. That said, here are my thoughts:
              • First of all, it would be helpful to know the overall size of this puzzle and how many pieces you're thinking of cutting it into. 1/2" BB is pretty

              Hey Denny---I shot you an email with a few questions. I might just have to dip my toe into the world of Pegas blades vs FD. At least to try! Open minded explorations. Thank you ! Linda

              Be careful---soon she will be able to outrun you! Remember when fridges lasted for decades?! Glad she's doing well.
