Does anybody have advice they would share with me regarding fitting the above tuners on a 1937 14 fret Dobro?
Should l clamp the strings with capos to maintain some tension on the cone or is this unnecessary?
Any advice appreciated.
I would think at some stage it may need a neck reset etc, but l don’t want to open it up for cosmetic reasons only to clean the cone etc and disturb the current setup. The intonation is adequate as it is.
Regards

Hi Chris. A tip I got from the forum and have used successfully is to very carefully 'jamb' something between the rest and the bridge to hold it in place while you slacken the strings. I've used a plastic tube 'biro' with good results.
It depends on the space between the rest and the bridge. The idea is to hold the cone in place while the strings are loose.
Hope this helps, don't be to rough and you'll be okay! 😎😊👍🎸
Best wishes to you all, John

I didn't install mine to Dobro, my guitar was/is an MMB, but they still screw to the side of the headstock right? I found that there was a slight raised area around the gear shaft locations where the metal had been peened over, and I had to relieve the timber slightly around the edges of the headstock holes to compensate. Without that step, the plate deformed slightly as I tightened the screws. Plenty of other folk have fitted these tuners and I don't recall anyone else having reported this. Perhaps no one else notices and just cranks down the screws? I don't know.
I used two capos to secure the strings, but more would be better in my view and forget maintaining tension over the biscuit, that's not going to be achieved at all, just keeping the cone and strings static is the best that can be expected in my opinion. They are good machine heads and the effort is worth it.

Thanks John and Stevie. It confirms the method l was going to use, so l am very grateful to you both for the guidance. It does give me some confidence.

Chris,
They should be easy to fit.
The advice you have been given is all good. We all have our own ways of doing things.
Dobro cones are less likely to move around than National cones, and the spider is screwed on to the cone. Personally, I wouldn't worry, I would just remove all the strings.
If you don't want to take the pressure off the spider, do them one side at a time. Just tune it all down a tone or two before doing it. Then take off E A D strings, replace and restring that side. Then remove G B E strings and do the same.
If you do want to remove all of them, it's fine to hold the spider in place with something. Personally I would use a chunk of washing up sponge as a wedge, then it can't hurt anything. On biscuits I use a piece on each side of the saddle, but not over the saddle. On a spider it should be fine over the saddle because spiders are much less fragile than biscuits.
John, Just my opinion, but I am not keen on the biro or stick-type object, because if you do bump the biro/stick by mistake, it could act like a crowbar and crush the cone.
Let us see this guitar when you have it all setup and ready.
Shine On
Michael

Here you go, that is the way I stop a cone from moving around when the strings are off. Just to clarify - that is two sponges, one either side of the bridge saddle.  Shine On Michael  |

Brilliant! Nice and simple, even pressure and there's no way a sponge could ever exceed the down force from strings.
