Hi Eitan and others,
I just want to say thanks for making the
Master Curvy Copter available. It really came out fantastic! For those interested in how I went with the finish:
I dyded it first (and last), it was useful to guage the depth of any sanding work.
Wash 5 mins simmer with detergent + water
Dye bath of 2 pacs Rit Dye, 2 heaped tablespoons of salt, 1 cup vinegar + water, 1/2 hour on simmer, overnight dry, rinse in morning.
400 wet & dry on any printer aliasing /starstepping
Dremel with 511E course @1500 (very lightly and only on larger surfaces) it's quite abrasive, take care if you use it near edges.
511E medium @1500 (all over and in the grooves)
800 wet & dry sandpaper on the flat sticker surfaces
423E @2000 (on the surfaces of the assembled puzzle)
Stickers from Oliver Nagy (and the process left the sticker surfaces completely flat- which increases their hold also).
Further conversation is in this thread (although I have refined my method a little):
viewtopic.php?f=9&t=23538And it would have been in a perfect state for tumbling, although it was about 5 hours work all up!
The jumbling is incredible, turning is very nice (I can actually turn all edge types with just one finger, including slices). Some care does need to be taken when it is jumbled heavily because there's literally very little holding some pieces in (this is not a design issue, it’s actually incredible to me that Eitan was able to make the parts hold in and function properly). It's a truely remarkable puzzle!
Congratulations Eitan.
I have solved it once without jumbling and it is fun to solve too.. Now to solve it
with jumbling

(I have solved severe jumbling while it was unstickered, and that was quite challenging, but I am concerned for resolving the changing orbits.
I thoroughly recommend this puzzle.
Cheers,
Burgo.
