  • Lower blade holder for RBI

    Has anyone found a replacement for the round nuts that is used to hold the blade on the bottom? There has to be a better way. If not, where can you buy the piece's to make your own?

    Thanks!

    What model Hawk do you have? My VS26 has "T" shaped screws top and bottom.

        Thanks for the replies!
        I have the VS 220-3 non-variable speed. The holder looks like the picture below. It unscrews into two pieces with a stud holding them together. Thee is a v-notch in the lower arm that it rides in. Just seems like a lot of work just to change a blade.

          Try contacting Bushton Industries. They are the ones still making the saw and they have spares for many of the saws. Phone is 620-562-3557.

            I have the same saw as yours, the 220 3 speed. Those bladeholders are a pain. I have 6 of them and, depending on the project, set up as many as I think I will need. Do you have the 2 tools to set your blades up? Stamped metal shaped like a letter "f" ?

                No, I don't have them. It sounds like that would be better then using a crescent wrench and open-end wrench. I'll have to contact them to see if I can buy a set. Thanks.

                  holder for RBI

                  There should be an elongated hole in the main base that one side of the barrel fits into and that sort of gives you a free hand to hold the blade in place. I had to build a new lower arm for mine (220VS) to get over to the new holders. At the time I had access to a bridgeport mill. Those holders are a bit of a pain. JIM L

                    I found the slot and it helps. It would help if there were more room. Maybe I could make a holder with a slot. I contacted Bushton and the price for the holder with bushing is $25.00 each. That's pricey in my book. The old price was $9.95. I think the way to solve the problem is to adapt a part from another saw. Just have to do some more thinking. LOL

                          Have you found a blade holder for your RBI scroll saw?? I just purchased a 220-3 RBI saw and want to improve the blade change method and the time it takes to change a blade.
                          Thanks Dennis

                            Holy Cow!!

                            I thought Hegner had the worst idea for blade clamps. Now I'm not so sure.

                              New lower blade holder

                              I have the 220 and after using the the blade breaking device that clamps the blade between two round nuts, I decided to build my own. I cut 1/2 inch round aluminum to 1 inch length. I cut two rabbits on one end so it will fit in the original slot for tightening the blades. I drilled a 1/16 hole in the middle across the diameter for a blade to go through. I drilled a 13/64 hole down the middle of the cylinder and and tapped it to 1/4 20 treads. I used 3/8'' dog point set screw from Fasenal on each side of the blade to clamp it. I then cut a 1/2 x 5/8 x 1 inch long bronze bushing to 1/2'' length and drilled a 1/16 hole in one side for the blade to pass through. blades last much longer now. I have made my own upper blade holder thumb screw by filing the last 1/8 of threads off and filing the end flat. The trick to flat is to pull a file across the screw sideways (not the length of the file). I was shocked at how flat I can get a screw end.
                              If I knew how to send drawing I would.

                                We have not. A visit to the doctor and he stated that once sick with covid, the antibodies are active in the body.

                                My wife and I got vaccinated this morning. I had worried that there would be long lines. But, the state of Indiana seems to have gotten it right. We went online 10 days ago and scheduled an bbc.co appointment. We got there as nd no line and went thru the check in, got our shots, waited 15 minutes...
