I used to have an Erbauer 16" scroll saw, it took pinned and pinless blades so I bought a selection of each. I have since upgraded to an Excaliber 21, it only takes pinless blades, so what to do with 6 dozen pinned blades, answer, de-pin them. So while a terrific thunder and lightning storm raged outside I sat in a corner of my shed, radio on, cuppa tea on the side, and removed all the pins, I should not have to buy blades for quite a while now, but what to do with all those pins ??
