There's sort of a spring on the inside. It squeezes against the arm as you tighten it. Here's some pics. Not sure what the metal is made of. But they claim it's "high precision japanese machining". Probably a high carbon steel of some kind.

Re: Red bishop - magik arm for trem

Looks more like some type of bushing to me. If it was metal the bar would squeak as you turned it

Well yeah it's a compression bushing now that you put it like that. But if you poke it with a screw driver it's definitely metal. As for squeaking that's not really always the case. There are pallet jacks I work on that the bushings and or pins that have a teflon coating that do not require greasing. Grant it over a long period of time they do wear out. This seems to be the same way. Here you can read about it.

Re: Red bishop - magik arm for trem

Teflon coating is treated on snap-in spring, so the bar rotation is smooth.

I read that but anything that applies torque will wear at some point. Granted not near as fast as factory bushings. But if it's a snap in "spring" that means it can be replaced? Because otherwise you're replacing the holder assembly to renew the torque adjustment.

You can see a wear mark on the bar. But there is zero squeaking, I do not feel any texture on the bar where the mark is. And it's super smooth in the arm holder when under full tension.

I guess over time it may need replacing. Though they do not seem to offer a replacement on their site. And that sort of has to be a bushing/spring because it expands back open when you losen the holder. Only a high carbon spring metal can do that... I mean plastic can but it's different.

Plus if it was plastic I would imagine you wouldn't see the wear mark on the bar it self.

Okay! Soooo I was scared to poke it too hard cuz I don't want to damage it. It is infact plastic of some kind. I have to push from the stop with a small flat head to see if I can feel a softness. Possibly a poly urethane? It's super slick whatever it is...

Re: Red bishop - magik arm for trem

It's got to be better than the V1.1 arm as the torque cap pushes against a bushing on the bar, so when you rotate the bar it likes to loosen the torque cap enough to affect torque. I've always recommended lube between the cap and top of the busing which does work.

10 years from now I still see somebody starting a thread their Red Bishop "spring" won't hold anymore and what a waste of money it was to have to replace the whole assembly. Only time will tell.....

Re: Red bishop - magik arm for trem

OK, make that 5 years from now, unless they offer the "spring" as a replaceable item [which I don't currently see], and they claim the cap cannot be removed.

Re: Red bishop - magik arm for trem

Now I see why they don't offer it for the ZR or EZ, only the EZ2 [V1.1]. It's the same thing with a different "bushing".

Yeah it's definitely a torque bushing of sorts. I do wonder what it is made of now... I've never seen black teflon. Though I have seen black poly urethane.

Honestly I think gotohs arm holder like their floyd or the new bridges on the AZ guitars are the best. With the screw in arm and bushing that adjusts the tension with a set screw. I wish they made a version that fit the edge. I'd get that for my lo-pro instead of this. That's one feature I love most about my gotoh trem.

Re: Red bishop - magik arm for trem

ZR bushing



And just for giggles, we all use teflon, we all cook on it, but long chain carbon is one of the most dangerous long term harmful common carcinogenic chemicals in the world, and 98% of the world is already polluted with it. And long chain carbon cannot be broken down, it's here and it's here forever.

That said I'm about to sear some scallops in my teflon pan.

Re: Red bishop - magik arm for trem

BTW, I sell very few of those ZR bushings, they seem to have a very long lifespan. The only reason I sell more Edge3 bushings is because they split with the toque adjustment screws, which was a poor design and the fact that you have to completely disassemble the trem to replace it make it an extremely poor design.
