Convert 10-1/8" Banjolin to 19-1/8" scale  22 fret extended Tenor

Style S Banjolin
Vega Style M Tubaphone Extended Tenor Neck

Neck off of Big rim Vega, I will pull this dowel and re-use the Style S dowel

The Tenor neck will be scaled down from 20 to 19 1/8" so that bridge will land in an optimum place with the new fingerboard

The old skin will be discarded and a Renaissance will be used

Nice old Style S neck, now available for another project

Style M Neck

Heel already was grafted at the factory, hence the extra laminate
I will pull it off here to do the dowel extraction

After cutting down a bit and finding the top and the back of the tenon, I'm pushing gently and its coming no prob


Dowel is deeper with no extra laminate so I have removed wood in the same manner
Dowel is tighter, will soften glue with alky and heat

A little Akly to loosen the glue, it does not swell the tenon like hot water

Out in a few minutes, no damage

Filling the void

Same on the Style M
You can see one is 1/2 tenon, and the other is 5/8
I will have to build up the hole in the M to use the small dowel

All back together and tenon holes redrilled

S dowel set in M neck and cured

New scale for this neck length will be 19-1/8"
 the orig 21" scale would push bridge too far to tailpiece end, choking tone
And it was made for an 11-13/16" rim, this is 10-1/8"
Compressing the scale is the answer

You can see where it will land in a normal place at 19" so that I can use a full length tailpiece.

Mocked up with some old #9 inlays for a looksee
This is 20 fret, the new board will have 22

Old board off and leveled for new board

I will fix this original Banjolin HSC because they are hard to find and it just needs a little TLC
I will glue in some new felt and just patch it up, not re-invent it.

I took off all the old duct tape and sealed the places on the outside edges that were loose.
Will dye it and shoot it with some clear, will be good for years to come.

Fingerboard - Allen Guitars

 19 1/8" scale
That's what I need to land the bridge where I want to on a smaller rim, so I can use a full length tailpiece without choking the bridge.
Thanks to Dale Small, for teaching me that trick.
If I'd left the scale at 21, you could barely use a No Knot.
Making it 22 fret extended instead of 19 gives it the Tenor/Plectrum capabilities
Spacing is close on the high register like a mandolin.
Size makes these Great travel banjos.

It's a tad long, I will trim it :)

Cut to profile

That's right where I wanted to be, close to center

Pulling out some inlay.
I'll go with pretty traditional stuff and a name block in case someone wants it.
I flipped one of TJ's  Vox III  19 fret inlays that Renee made for us on another project that we did not use.
Will not put any partial frets on the extension nor will I put a non themed inlay.

Starting the cavities

All in, dyeing the peghead

Fretted and new nut fabricated

A light tobacco brown to make the neck / dowel match the rim, slight fade at heel and peghead
re-blackened the bottom on the rim, added 3 fresh coats clear Lacquer

I wanted large side markers and the material arrived, that's next.
Then 2 more clear coats, while I buff the hardware and find a tailpiece/tuners

Markers going in.

Modern 4:1 tuners

New Skin head installed
