I sold my Bob Lum Chinese folder to an idiot >>

[paneraica]

Was mint and never used. Sold it to an idiot who bugged me for a year and was willing to pay double for it. 3 days later. I get a call and he wants to buy a cheap watch I had (didn't pay for it).

Show up and he shows me the damaged knife. He was throwing it against a tree and it vibrated the scales to the point the threads were stripped

Traded the watch for the knife.

Emailed Spyderco to see about purchasing new scales, but was told they didn't sell or ship them. I could send them the knife, but no warranty. S/H from Canada to the US + scale costs (discontinued green anodized, so no idea what they had) would cost way to much.

Bought slightly larger screws and works, but not perfect. Screw head just a hair larger. Ground down the screw by a half mm to sit flush. Will do a test grind on a spare screw head for a better fit.

Told him not to call me anymore. Too much of a headache

Wait......WHAT??

This pains me. The fact that the threads are both tiny and tapped directly into aluminum are a huge design flaw IMO. I've stripped one out by accident just during reassembly, and I bought a user that had them already stripped. I managed to fix it with a quick mod though and it works way better now:

Spyderco said the scals and clip used a Torx 6 screw. I bought some M2 9.5 mm. Ground down the head to the same diameter, but head is still taller, so sits a little raised. Grinding the face will lower it, but would also lessen the slot area quite a bit

M2 just barely cuts into the old threads, but holds. Ordered a couple of M2.5 x 9 mm, but that extra .5 may be too much. Also just checked and head 5.7mm and needs to be a shade under 4 mm to fit the scale hole. Not sure I can grind 1.5 mm off, but will check when received

Was thinking maybe new G10 or ivory micarta scales. Hard part would be a pivot hole as it has a flat face to hold one screw side. Routing out the area for the lock spring would have to be done before scale cut to shape.

Need a mill to do aluminum. Probably could router aluminum, but extra work

I'd pay for a full g10 or micarta scale set for the Lum Chinese if you end up making them. Sounds like a lot of work though. I'm pretty satisfied with my solution though since there's no chance of stripping out the aluminum again.
