I thought I had the correct head in stock for it, but its not the right crown.

I ordered a REMO Renaissance from in  12" medium and low crown.
Its hard to say what crown is best, because of the neck notch.
Possible mods to make it have clearance for a modern stretcher band may be in it's future.

Original flesh rings on skin heads are half the thickness of a modern Remo band.
Flesh rings on hide heads are small and these banjos were designed around that.
Nothing I have not dealt with in the past.
Saw that is used to widen/deepen when binding is left on.
Teflon dams, building up divots
Compression fretting with 147 Stew Mac wire
Now to fret over the heel
Ready to level-re-crown-polish
Little or no finish is left. 2 bushings missing

I will wick in #10 and then pressure the neck flat while it cures

Wicking in #10, it goes all over into places that cannot be reached with other glues.

Now to finish the clear coats
Fretwork completed, leveled and crowned/polished
Went with simple down force tailpiece and a Gibson Style armrest
Bridged and strung to pitch, settling in

Ed decided on a No Knot, so I changed it out and did a new setup.
Last mod will be to lower armrest bracket, cut and re-solder.
Now it will ride closer to hoop, Farquhar Cherry Bridge
Next to my Stromberg, settling back in.
Found a handle and fixed it up.
 Off to the "Manhattan Minstrel" it goes.
Another fun project, its always a blast to work with Eddy.
Thanks for watching,Vinnie
