Vann5,
Sorry about not replying sooner on this. I didn't think about the reverse thread on the handles, so you're right that finding a tap would be difficult and most likely expensive. Let me know how the wooden handles turn out. Right now, my nephew's have just stuck whatever rubber foosball handles they could get their hands on on the rods (I'm taking the approach that the less questions asked about where they got the handles the better), and it looks awful. So anything would be an improvement. I don't mind throwing a little money at it to get original replacement handles, but I wouldn't want to spend more than $100 or so.
Thanks for your reply
