GIBSON MB-1
FON # 8819-25
RARE 40 HOLE ARCHTOP TONERING ON 10-1/2" RIM
 



Initial Pics


Excellent example with OHSC
Yellowstone head


 
 


 


 
 
 
 


 
 
 
 



CONVERSION

Convert to   TB2 4 string 19 fret neck, 23" scale
Period neck with "Nick Lucas" style inlay

 I will use it until I get my new fingerboard in
I think compressed scale and 20 frets will be the choice for optimum bridge placement.
 


 


 


 


On top of a 63 model RB250 archtop
Double decker???
 


Here is the tenor neck I'll be using.
And since I will be making a "Mini Mastertone"....
 

..I have a donor 26 TB3 here for the Mastertone block..
 


Retro fitted...
 


Refret with #147 wire, fingerboard oiled up
 


New Mission Brown finish and added side marker dots



ASSEMBLY
 


Using the old tiny lagbolts so I can use orig rod and nut

SIZE COMPARISON to the "BOB WREN" TB4
 


A few different angles shows the smaller overall size of the 10 1/2 short scale.
 
 


 


 

 
 


 
 
 

The method the artwork was done as follows...
The blond area is not an overlay, it is where all of the finish was removed in a circle to show the original blond maple color
Then the drawing periphery was scribed, details of the drawing added to it and then black was added in a smaller circle to give contrast.

New Head
REMO RENAISSANCE
Add upper Co-ordinator Rod (Original 1927 Gibson)


I had a pair of original small rods from another old  TB1 so I sized one down to fit the 10-1/2


Like it was made for it....
 
 


 
 

And the new medium crown Remo head.....


The banjo plays out well, with a tone not heard from larger rimmed banjos, it is bright and concise, super single stringer and not wishy washy on chords.
After all, it is a real tone ring we have in here.
Can't wait to hear it on the 20 fret board
 
I can imagine it in GDAE tuning, nothing could compare to it.

New Fingerboard ordered - Allen  20 fret - 22.050" scale


I want the banjo to have a more optimum bridge placement as well as a closer scale with a full 20 fret board so I chiseled off the original and laid a new bottom veneer.
 


  NEW FINGERBOARD - ALLEN GUITAR
22.050 Scale
20 fret - Rosewood


Temp TB3 neck on for the weeks I was waiting on new board, looks pretty cool .

Ready to trim to profile
My Pal Donna at Allen Guitars was worried that my ordering a 1-5/8 wide board was too slim...
She is not used to Tenor banjos!
 


 
 


A little more reduction needed to use the correct  .040 white celluloid binding, not plastic.


Bound and leveled, 1st coat of oil ready for markers and then I'll stick it to the neck

THE NEW SCALE


With the 20 fret fingerboard at 22.050", Im measuring off to see if my calculations for the 10.5" rim were correct.
I've laid it over the TB3, same length where the 11" mark is on the ruler is the new bridge placement
 


So it will come back toward center that  11, giving the tailpiece arm room, reducing the pressure and string angle.
It will wake it up to be the instrument I expect it to be.
It's VG now, I want it to be Top Flight.



INLAY - FRETS

After much soul searching I have decide to make it what it really is.
A  1927 "1" series Gibson, that was factory upgraded to Mastertone
So in my mind I want it to have the the block, and then its normal dots.


 
 


 
 


MOP nut installed


Commissioned the neck with matching #s and stamping



ASSEMBLY


 
 


Elevation is where I want to be as is scale length and bridge placement


That just looks "Right"
A TB1 Mastertone, that's what it is.
I'm  very happy with the initial test  



FINAL PICS

I've opted for a Kershner Short arm tailpiece to get more adjustability and a longer string gap, it really opened it on up as I had hoped it would
 


Rechalked the FON#
 
 


 
 


 

 
Now its time to enjoy it for awhile, there is no way I can see this thing staying around once others hear it.
