So I got an OC Farmer with a broken saw. I figured it was high time I tried a mod. I've removed the outer pins and will replace with torx. I was going to take it all apart but for some reason I stopped short. I have been looking over the threads on how to put a 91mm scissors in. . I'd like a OC Farmer X but I lack liner skills and well, all other skills to pull that off. I'll stick to just torx pins and drilling out the 91mm saw pivot hole for now. Wait.... Anyone have a 93mm saw sitting around? I just need to source the torx parts and off I go.
For the torx parts, they're 1/8" diameter not 3mm so you'll need to drill the tools, springs and liners anyway.
As an alternative to driling out 3mm to 1/8" you can use this trick to build your own 3 mm (and 2.5 mm) pivots out of brass stock, but you'll need a lathe.
You can use a Dremel and a carbide tile cutting bit (#562) to open out the holes to 1/8".
