WTB Yamaha PX-3 heavy counter weights

Looking for the heavy counter weights that came with every PX-3. They screw into the rectangular counter weight in place of the little screws. I would make some but the thread size is not a standard size.
Might be interested in a whole PX-3 parts machine as well.
Thanks

Probably a standard metric size.

Cheers,
Alec

As a machinist I know what is standard for both imperial and metric screw threads. It's an oddball metric pitch. Yamaha obviously didn't want someone hanging a ton of weight off of it.
But thanks for the try.

Why not drill a size larger and tap out to standard thread

Hi Mike, that would be very easy for me to do but I'm not about to modify a classic, high end, and fairly rare TT.
I did find a very small selection of screws with the proper thread pitch (M4 x 0.5) and purchased 2 pieces. Now I can screw some weight to the back of the tonearm until I can find the proper weights.
Thank you for your suggestion though.

Still looking if anyone has some weights.
