In takes a different type of thread to put a lid on a box with only a 1/4 turn.
I've never tried it but one might be able to accomplish this by cutting out
sections of thread in both the lid and the base so that the section with
external thread slides through a slot in the internal threads. Then rotate about
1/4 turn should tighten things down. Again, I've never tried it, but this should
accomplish the 1/4 turn concept. It wouldn't look too great, I don't think.

I beleive the "Bonnie Klein" standard is 1 and 1/2 revs. I agree...1/4
turn is not enough.

My complaint with threaded boxes is that it takes several complete
revolutions to separate the lid from the box. It shouldn't take more
than a quarter turn to remove the lid. More than that and I think I'd
find it annoying with frequent use.



One quarter turn to un-screw the lid? Can we assume that three-quarters of
the lids' thread will be unmated? Why have a threaded lid on the box?
Seems a suction fit would suit you better. I just checked my Richard Raffen
cocobolo threaded box. It takes one and a third revolution to unscrew the
lid. Not annoying at all and it sounds like it is made of porcelain....Nice
sound. However I agree that a lid that takes several turns would "grow old"
very quickly!
