[hackR]

Hi Guys...am at work - so i don't have a dw with me...can someone please accurately measure (calipers) the diameter of a 7750...looking into making or buying a ring for the sunken dw mod on a couple v1 Navitimers...inspired from both Francisco and Importr's recent work on this mod...

Here's a pix of the measurement i'm looking for (the red line) from Francisco's terrific post on this mod:

thanks for the information...R

thanks, Tom...

Just found this info online from ajoesmith...

Inside diameter is approx 18.25mm

Outside diameter is approx 24.55mm

normally I'd say 'What's a half a mm among friends?' but in this case it does make a difference ... good luck with the project!
