Question....

[BigBubbaG]

Now that I have a 788, which doesn't accept pinned blades, I have a couple dozen pinned blades that are no good to me.

Is there a way to get the pins out without damaging the blade? 

Or, are these blades now trash to me?

I sure do not know the answer to this one, but I wonder if one could grind the pins off with a bench grinder. Not sure at all, but perhaps you could give it a try and see what happens.

If you grab the pin with a pliers and wiggle it a bit, it usually pops out.

Thanks. I'll give it a try

I had thought of that. My concern would be heat. If it gets too hot during the grinding process it may ruin the temper of the blade making it weak and break.

I'll let ya know how it goes.

Thanks again!

Drill a small hole in a piece of scrap metal (1/16", I think, is what I used.  Maybe 3/32"), put one side of the pin in the hole, tap with hammer until flush.  Then poke through with icepick or punch or use needlenose to pull on through.  Attaching the metal to a scrap of wood with a larger diameter hole through it helps.

 

Basically, the pins are just pressed into holes in the blades,  held there by pressure.  They're not soldered or welded in place.

Got my blade order from Bear today. Now if it will warm up enough to go outside.

  I would do what  Rabid Alien suggested except I would use a piece of maple, easier to drill.

I used a scrap of 2x4.

By all means. I have way more 2x4 scraps laying around than maple.

More Great tips.  I haven't used pinned for 2 saws but I kept the blades ( just cause they sat in a corner and didn't bother anyone) Now I can get my monies worth out of them again.

But, are they any good? Most pinned blades are probably junk. I would think anyway. And too big for most projects.

I have some pinned blades (Olson) that are pretty small.

I have to agree, most of the pinned blades that I have had and used eons ago are huge. I kept mine for the copping saw but for the scroll saw they are way too big for my work.

Pinned blades are only limited by the size of the pilot hole and the skill of the operator.  They can still cut some pretty fine details, as long as you can get a hole in there for the blade.
