Seimitsu Bubbletop on a Ultimarc U360?
<< < (4/4)
Franco B:
Im not sure if it would be too heavy or not. I wouldnt desribe my JLWs (which what the U360s are based off, though im not sure if they are sprung different) as light but the added weight may affect the feel of the stick.

Someone else has already asked me about stainless ball tops and I have been giving it some thought. Nomally If I was making one for me I would turn the lower part of the ball and drill and tap the thread before flipping the component round and screwing it onto a M6 shaft to turn the other side of the ball before polishing. The only problem with this is its far too much work and they would end up being too expensive to sell for what they are.

Im going to see if I can get hold of some ~35mm ball bearings to adapt. I could then just make a full radius split bush and then just face a small flat on them and drill and tap them.

Once again these may be too heavy but its worth a go.

Or I could just hold them in a vice and spotface, drill and tap them, talk about over engineering things   :dizzy: :laugh2:

Ive just found a supplier that will be able to supply some balls (oo-er). They also do chromed aluminium balls too which would be much lighter. Im just getting some more info from them.

What about somehow adapting the existing "Versa-Ball Mirrored Stainless Ball-Top Joystick" from Groovy Game Gear?  Maybe you could adapt the shaft, or rethread the ball, or just make an insert adaptor, like Lizard Lick makes for the Sanwa ball tops.  I'm just thinking that there must be an existing stainless ball top (because I see them on lots of CPs) that just has the wrong threads.
