Baldwin Burns Rezo Tube Damper Screws

[stu77]

Quick question, can anyone tell me the thread size and length of the screws for the damper on a Baldwin Burns Rezo Tube bass bridge please?

Sorry, I came in here expecting to see this Baldwin fellow give those %*@#$! Rezo Tube Damper Screws the scorching takedown they deserve. They've got it coming.

I'll see myself out....

I have a transition era Baldwin Shadows bass with the Burns bridge and pivot plate that the mute screws into. The Burns mute is a slightly different design than the Baldwin.
The Burns model uses M3.5-06 slotted head machine screws 1" in length.
Test the fasteners in your base plate. I tried everything. And I mean everything.
They are not UNC #6-32, UNF #6-40, M3-0.5 (50TPI), M4-0.7 (36TPI), or BSA 5BA.

Nothing fit properly until I realized someone had damaged the threads in the pivot plate.
I retapped the threads in the plate to clean them.
We welcome, ok, I request detailed measurements of the Baldwin mute if you have them. I need to make one. I can estimate lengths from photos, but can only guess at material thickness,

Thanks

Haha, I have read on another thread on here that they aren't the best. Either an ON or OFF kind of situation but I'm curious to try one out and had a notion that if I use a couple of springs under the top plate like on a pickup it might have some tensionability (if that's even a word?!!!!!).

Ah, I'm just eyeballing the size of the top plate myself tbh and knocking one up for now as a proof of concept idea but if it works as planned I'll be on the, possibly fruitless hunt for an original. I too tried many types of screw thread and finally found that a 4BA seemed to be right but I wanted to see if anyone else knew the correct size and if that was correct?! As I mentioned in a previous reply I'm wondering if a couple of springs under the top plate will give the desired height/pressure adjustment to make the damper a viable proposition?! I'll keep you informed anon!

Springs would be useful. The holes in the top bar are not threaded. Springs would allow the mute to be disengaged while the mechanism remains mounted to the body. The absence of springs meant the mute needed to be removed and always lost.
I have had some success with responses from sellers that have the mute still installed. Just no one willing to make an actual measurement.
Of course it never worked very well.
