I have a 9 inch Langstile pot that has been sitting around for several years needing a neck. I have been wanting to make one for it but other projects keep getting in the way. The pot was probably a banjolele but I don't know for sure. I would like to make a small scale five string out of it and string it with nylon strings.
My question is, what would be a good scale length for that size pot? I am leaning toward 22 1/2 to 23 inches. Would that scale be OK or would I be running into problems? Luthier's Mercantile can make any scale I want, I just want to know if I am running into any unforseen difficulties.

I have used 21 5/8" for eight and nine inch pots and had no issues, so I doubt you will with the scales you are considering.

Thanks, Verne. I hoped I was on the right track.
I am planning a 20 fret neck so I will go for a 22 1/2" scale.

I have one I built with an "8 head, top tension with a all wood pot.  The overall diameter is "10.  I used a Gibson scale template and chopped it at the second fret, so just a tad under 23.5.   I think it works pretty good.

It depends largely on how many frets clear of the rim.

For tone the bridge should be about 4/11ths of the diameter from the tailpiece or a bit closer to the centre for a softer tone.

You can pick where the bridge is positioned by adjusting either the scale length or by adjusting how many frets at the rim end of your neck.

I have made some 20" scale 20 fret necks on 10 " pots that tune to open G using baritone uke strings with a mellow tone. A 9" pot might just put the bridge in a bit better place about 3" from the tailpiece.

There is a prominent mark on the skin head where the bridge used to be. I want to keep the bridge in the same place and build the neck to fit without extending the fingerboard over the head.

I have an original Fairbanks "Baby Electric". It has a 9" pot and a 21" scale.
