Fine work on my 2009 home made Pineapple soprano.
13 mm. head thickness.
( Think don't fit under 12mm. head thickness ).
Tilt green light is so easy.
22 g. on my precision weight scale the complete set with screws.
They look pretty good on that Uke. If they feel and work smooth, anything they do cosmetically will be a onus. Thanks for posting pic. You got your out before they started refinements to look but I bet they are just fine.
To M3Ukulele : Yes, they work fine, smooth and providing precise fine-tuning, and at 22 g. the set, a real good choice if you want geared machine heads,
but realy, I prefer the look of friction tuners.
For me, nothing could beat on this field Waverly Vintage ebony button tuners ...
