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

I ordered a REMO Renaissance from
www.bedfordbanjoshop.com 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

FINAL PICS

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
