  • Blade converter for vintage scroll saw?

    I have a vintage PowrKraft scroll saw, that unlike modern saws, really was built to last and still runs. The problem is, it's a major PAIN IN THE NECK to change the blades, and it doesn't accept pin end blades, which is what I mostly use. Most of the time my scroll-sawing consists of rough cutting shapes for whittling. This is the kind I have, with those big hex nuts and a small allen screw to hold the blade in on the top and bottom: http://vintagemachinery.org/classifi...l.aspx?id=2267
    Any recommendations would be helpful. I tried 2 of the Central Machinery scroll saws from Harbor Freight, and they were basically unusable. The first one had no power to cut 1" pine, and ran erratically, and the replacement had huge blade wobble from side to side, and the blade was obviously off-kilter (I had a very noticeable tilt to the table to get it perpendicular to the blade. So I just got my money back. Research online shows that all the cheap and mid-grade options are basically the same saw as the CM one, just with different branding, and the amount I use it isn't worth it for me to spend $500 or more on a scroll saw. Plus the expensive ones are too big to fit on my work cabinet. So I figured I might as well try to fix up the old vintage one in the basement.

    This looks like it might work, if it can fit on the shaft after taking the hex nut off? Maybe? https://www.amazon.com/Scroll-Blades.../dp/B0B46M8W2V

      Most scrollers want to go the other direction from pinned to pi less. Without seeing the machine in person the only thing I can think of is to make or have someone make adaptors. If you take the blade clamp nut off is there a split collet? Now it obviously has a slot the blade slips into. If that collet had a round hole then you could take a piece of rod with a slot and notch to hook the pinned blade into.

      I would stick to the pin less blades.

        A closeup picture of the blade holder would be useful.

          I hate pinless blades, at least on this old saw, because it takes FOREVER to get the blade to actually stay in! the pin end blades you just pop it in, and it necessarily stays in because of the pins. I don't do fine cutting, mostly just rough cutting the shape for whittling.

            Here's a picture- There's a blade in it now, so I don't want to take it all apart and take the hex nut off. IMG_3108.jpg

              How many times will I make a cut for inlay, then forget to reset the blade angle to 90 degrees? UGH!

              Rolf, on your second picture did you resize O Holy Night or was that the angle of the camera? How did you carve the bowl behind it? A little birdie told me I was getting the rest of what I need so I can do bowl and spoon carving. Actually, I told the bird what I needed/wanted. Your work is amazing.
