A friend has recently acquired an old Ludwig tenor banjo and asked me to build him a neck. I need to drill the tuning peg holes and he wants to use the original tuners. He eyeballed the tuners and said they are about 1 mm over 1/4". He lives about and hour and a half away in PA and with the Covid mess travel for right now is not possible. Can anyone give me better specs?
Ask him to mail you one of the tuners.
I would think even better, have him put the tenor neck in a stout mailing tube, so you can have the benefit of it as a template yourself.
Mailing tubes offer excellent protection and the postage isn't much.
Or ask him what tuners are on there. My Ludwig Ambassador has original Planetary tuners whose dimensions should be available.
If his Ludwig is a top tension,the front two bolts are very close together.it hard to fit a 5 string fingerboard between them and make it look good. I know because I once had one.
Just something to plan for.
I'd ask to see the entire tenor neck. There are some oddities with Ludwigs that wi9ll affect the fit of a new neck. There is the top tension issues referenced by Rod Durst. There is also the Ludwig rim size, which is 10 3/4 inches. Some of the Ludwigs also had some strange neck attachment systems, some of which were adjustable.
Thanks for the replies. As per suggested I requested him to send the peghead overlay and a tuning peg.
