A lovely pair of balls dropped through the door in their bag this morning. Thanks @Baysearcher your ball is in my hand as we speak.....
Yep all three of the purple balls are still available. Not sure what the empi thread is, doe sit even come off?
I'll try and find out the thread, it does come off I ordered an extension piece for it but that was wrong thread
If you want to send it to me i can have a look and measure it. Was the extension piece too big or too small?
Apparently it's an American thread ⅜-NF, A.K.A. ⅜"-24, does that make sense to you? The extension was 12mm but was too big
Ok I just checked, do have the tap but unfortunately the holes I drilled for m12 are too big so I can't tap it to the size you want. I can do you a red or yellow!! Or you can send me a ball and I can drill and tap it or I can be one and do it that way. Will cost a little bit more though
