Aquatica Focus Gear for Canon EF-S 60mm

Hi.

Is there anybody who owns a working Focus gear for the Canon EF-S 60mm (18710)?

If yes could he/she tell me the internal radius, external Radius and the thickness of that gear?

The reason why I ask this question is that Aquatica sent me twice a gear that does not fit on my housing A20 on the 60 mm EF-S Lens.

Maybe the age has destroied too many brain cells of mine so that I'm not able to mount a gear on the lens; but a friend of mine received a 18710 focus gear thicker than the one that I have received twice, perfectly working.

Many thanks

Salvatore

I have the exact same setup at you: Aquatica A20 with 60 macro, and my focusing gear works perfectly. Call blake at Aquatica @ 514-737-9481. He is very helpful.
