  • rbi scrollsaw broke

    I have a rbi 220vs that the variable speed control does not work, motor works fine. Got in contact with hawk but they don't carry parts for the variable speed control. Called grainger but they don't carry variable speed control for ac motor that has a capacitor. Hawk does have a dc motor and control but want's 350.00
    dollars but i really would like to fix the one i have. I tride to get this one fixed but it has a special chip in it that they can't find anywhere.Can anyone help please.

    Could you plug the saw into a variable speed router switch?

        Many of the metal working "mini-lathes" use this type of control. You could try on the mini-lathe group on Google. There was a place in Arizona(?) called Uncle Rabid's that repaired them at very reasonable prices. All that Hawk wants to do is to scam you into buying an expensive replacement.

        You can try these places:

          I was hoping to see a good answer to this question as I have the same problem. Had a wire short out and when I got it repaired, the motor runs fine but the variable speed controller only has one speed - ultra fast.

            Have you tried a electrical motor shop that rebuilds motor?


            Another option could be one of these:

              AC/VS drive

              That drive with the Capacitor AC motor also used a 16 point magnetic wheel that provided speed feedback to the controller. Sometimes those shatter and all control is lost. I found mine on the floor once and glued it back together. Have been on lookout for a new wheel, everytime I get into a site with electronic parts and to no avail. I read where others on this forum have lost the timing wheel. For what its worth. If Bushton provides a replacement like on the newer 226 VS and G4 series with DC drive then their are several machined parts and a bearing that could justify the cost. I wish they would publish a catalog. JIM L

                Jo, when I got my hegner long ago it had a light with it. In the back of the light was an outlet for the footpedal. I put in a 3 prong plug and plugged in my footpedal and vacuum. Ran great for 15 years. A few years ago the outlet on the lamp died and my footpedal at the same time. I had to replace...

                Conversation with Bruce. I need some beads for the dream catchers. Bruce - let me go look through my stash. I have what you need. Me - of course you do. When I first started doing shows, Bruce would go and make dreamcatcher earrings and other jewelry. He was quite good at it. Of course he was. He kept...

                The saw was plugged into a Festool Midi vac, which was plugged directly into a wall outlet.

                Rolf, could you explain your setup again? It appears your saw is plugged into foot switch which is plugged into outlet strip. Where does the Festool fit? Does it turn on when saw starts if it is...
