My mame cab is one that will have pinball support as well. My CP's got the side mounted flippers, I'm likely going to use either a WIIMOTE or a uhid for tilt support and I picked up a plunger a while back on ebay.
Thing is it was all chrome, which didn't work right with my cab at all.
So I found a local guy that does brass plating. Well, long story short, that as more than 5 +months+ ago (when he told me the slowest he'd have it done by was 6 weeks!). Yeah, I was pretty much thinking I'd never see my parts again.
I finally resorted to pestering the hell out of the guy till he relented and finished them up, and I got them back.
Well, in all those 5 months, the guy NEVER thought to call me and tell me he couldn't plate the damn aluminum knob on the end of the plunger! Jeez, talk about great customer service!<sheesh>
Anyway, so now I have a nicely brass plated pinball plunger with an aluminum knob on the end!<urg>

So, here's want I +want+ to do.
I found a nice victorian style cabinet knob, standard screw mount.

So I'd like to take the aluminum knob off and put this on.
BUT, it looks like the aluminum knob has been hydraulically pressed on.
I could pull out an angle grinder and get it off, but then, given that the plunger rod looks like stainless steel, i'm not sure even IF I could drill and thread a hole in the end for a screw to mount the new knob.
Anyone have any suggestions?
