  • Need some help Excalibur scroll saws

    I actually need help with 2 different ones!
    1/ Mine is the variable speed DC motor one in which the "circuit board" is no longer working. The motor checks out fine and the motor guru says it is the DC speed controller.
    Anyone have a lead on a used one or even something NEW and better. my electrical guy says the DC motor is 90V and just under 3 amps

    2/ picked this one up for the grandsons. It is the EXII model with the 3 speed pulleys for variable speed. Problem is the Original owner lost the 3 speed aluminum pulley from the saw!! I got a bag full of stuff and the pulley was gone.
    I have the one from the motor. It IS SMALL 2.5" is the BIG groove and the middle is 1.75" the smallest is 1" with a 5/8 hole for the shaft.
    Mike

    Re: Need some help Excalibur scroll saws

    If the HP of the motor is 1/2 or less, one of these would probably work. It wouldn't be as pretty as the original but believe that it would be as functional. https://www.ebay.com/itm/AC-110V-DC-...W/264524585767

    I use these all the time for variable speed on lathes, drill presses, bandsaws, belt sanders etc.

          Hi Mike, Its dead easy. AC power attaches to the 2 top positions on the controller marked AC. There should be 2 leads (and possibly a ground wire) from the motor. The 2 hot leads attach to the controller in the marked motor position.

          I am not sure if it will make a difference with your saw, but if after you wire it up, you find it is running in reverse, just reverse the motor connections on the controller.

            Thanks. Dead easy for “ electrical guys”. I am terrified of electric power!

                Ok Rory the controller has arrived. What do I do with the on/off wire positions??

                  Ignore them. Just hook up the ac and motor terminals

                    What kind of a box do you use? It is a lot deeper than a regular one.

                      Like I said, it won't be as pretty. I build wooden boxes and mount them in a convenient location on the machine. Here are someexamples.

                        Ok. Looks fine. Was worried about the wires in the back. Thought I could find a deeper PVC or metal box to stick it in

                          You can do that too, but I have found it easier in the end to make my own, of course I have a scroll saw to cut out the hole for the box

                            Another ? Do you have a fuse in-line and if so, where? Previous one had a 3amp SLO-blow fuse.

                              There is a fuse in the controller.
