See photo. The hole in the second trigger is for a bar to help distribute the weight and is secured with a set screw.
The one pic is of a Greenhoe and I'm wondering where I can buy the hand rest and screw. I figure knowing what the nomenclature is I can call or email an Greenhoe dealer and sound like I know what I'm talking about. Shires makes one and I hope they might fit a Greenhoe.

Anyone have one and/or know how I can get one?

Of course, if anyone has a used one I'd be very interested in that also.



Thanks!

Uh oh, I don't have this one on the list... is this a newer Greenhoe?

Shires has a similar rest.

It's an original Greenhoe that formerly belonged to John Engelkes.

I've played that horn! Didn't notice that. To be honest I've never heard of a Greenhoe rest bar like that one. I wonder if he did that aftermarket.

Same on my horn (definitely not custom):
It is referenced with a CAD mockup on Doug Yeo’s site: https://www.yeodoug.com/resources/faq/f ... nsion.html

The Greenhoe website does refer to rest bars, though the one pictured doesn't seem to be the type that fits in the hole for your second trigger.

That is correct.

The 2 holes were designed into the Gb lever bridge, but the accompanying brace parts were never done in the GH shop.

Which shop might have made the accompanying parts and hopefully, still do?

There were no accompanying parts ever made.
It wouldn't be a huge ask for a half decent tech to make them, though.

Question for the hive; would the shires part fit?

I have a Shires valve section, I could take a few measurements on that if it would help. Anybody have both hanging around?

Cheers,
Andy

The larger hole on my GH is 6.22mm and the smaller, threaded hole for the screw is approx. 3.15mm.
I reached out to Shires by email but it's early so maybe I'll get an answer in the next day or two.

The rod for the rest bar on my Shires bass measures at 4.85mm

What's 1.37mm between friends?

Possibly the difference between being able to generate enough clamping force or not. I'd suggest getting someone local to make a rest bar for you out of 6 mm rod (it's a standard size). Make sure the screw is the right size, too (you might need to make a little excursion to a really good hardware store).

6.22 mm is just a few thousandths less then .250", so you might want to check to see if 1/4" rod will go (it probably won't, but it's worth a try).

Matt, if you're still reading this thread, did you ever hear anything about why the accompanying parts were never made?

No idea really why they were not put into production. There were maybe a couple made, but I have no idea where those parts may have ended up.

Keep in mind with the GH bridge, the screw hole is not at 90⁰ to the rod it would secure (unlike the Shires part) so, you need to have a small piece with a radius (to suit the rod dia.) machined on one end. It would free-float inside the hole, with the lock screw pushing on the insert, not the rod.

Thanks for the info.

I never did have much faith in a "single setscrew into a rounded surface" setup; too much force applied over too small an area (seen it many times on camera tripods). Using an insert such as you describe would spread the force out.

Yes, but it does complicate the production of parts. Also adds to the very real possibility of lost parts. It was quite effective, but really fiddly.

Yeah, the world is full of things like that.

Interesting thread. I never thought the holes on my Greenhoe lever saddles (bridges) were intended for any type of grip aid or handle. I assumed the holes were there for acoustical reasons. I figured that reducing the weight by a little would give the horn a better response.

That's what I thought until I noticed a similar thing on one of my Shires 2nd trigger bridges.

The thing that got me thinking was when I noticed the smaller hole is threaded for a set screw, so then the light bulb went off in my head.

I did receive a Maiocco grip yesterday and love it. Had to do some custom bending and stuff to make it work the way I want it and for $15 plus shipping, it's a winner!
