Hi Guys,
I am looking to adapt an old electric woodworking scroll saw for lapidary work, something similar to a Hegner saw.
Now I know I have previously seen suitable diamond wire blades but can't find them again for the life of me, they need to be 5 inches long with a plain or pinned end.
Anyone seem them?
Cheers
Dave

The Omni blades are 7" long with diamonds in the middle 2" or so. I have lots of three packs of them. The ends are round and smooth. They fit standard jeweler saw frames as well. 3 packs for $10 if anyone wants some. They changed manufacturers and I bought all their old stock thinking carvers would want them.

Dave, the only problem I see with using a scroll saw is converting it to be run wet. I believe they do make diamond blades for scroll saws. I'll look around and see what I can find.

I'll measure the Gryphon Omni blades tomorrow. Diamond doesn't go full length but cost is much less. I have thin diamond blades for jeweler saws that are $10 ea. The Omni blades are thicker and with coarser diamonds on the section that has diamonds.

Hey John, did you get that measurement ? I have a very old Dremel scroll saw that I'd like to convert, but it takes blades that are 3 or 4 inches long, and takes pin end blades.

Just wish I could find 3" pin end diamond blades for my Dremel saw. I'd like to try converting it, since I have a larger new scroll saw.

Sorry, Don, I got distracted playing in my sand box. The Gryphon blades are 1/16" thick at the ends and 7" long. The diamond surface is 2 1/4" and offset towards one end a little. The diamond surface is flattened out. The $10 diamond wire blades are 1/16" and 7 3/4" long. Diamond covers entire surface and is round. Both type blades are round on the ends. What is "pin end"? Bent on ends? I would really like to sell some of the Gryphon blades. I usually get $15 for a three pack. $10 per 3 pack is a good price but for 5 or more I'll take another 10% off.

John - my craftsman woodworking scroll saw uses pinned end blades. The pins are what hold the blades in place. this picture shows the pins Chuck Attachments:

Hey John, pin end blades are flat blades with a tiny pin through each end. I'm gonna check my Dremel saw, and see if it can be converted to round blades. If it can, I could probably cut those Gryphon blades in half to use them. They would probably work in my new scroll saw as is.

I know they clamp into standard jeweler saw frames. I don't know how the Omni clamps them in. If you can use round ends you could easily trim the ends to fit with the diamond in the middle only.

My new scroll saw will take round or pin end blades, but I hate to modify a brand new saw to wet work. I'm gonna check to see if my old Dremel can be converted to use the newer blade clamps.
The old scroll saw was made by Dremel, but was also sold by Montgomery Wards and Sears under their brand names. Sort of like some of the tumbler manufacturers used to do.

I'm always amazed at the look I get from people with Sears or Craftsman power tools when I ask them who made them. They usually argue Sears. They can't be convinced Sears resells products made by others. I was able to buy 25 "Craftsman" MK 145 tile saws years ago that MK was trying to clear out. I had to swap out the Sears manuals with MK manuals and advise customers not to take them back to Sears. They had "Craftsman" molded into the housing where the "MK" usually is.

Yup. My old scroll saw has a Montgomery Wards decal on both sides. But otherwise is identical to the early Dremel. It even has a side shaft to attach a flex tool to.
