    Need a quick measurement Betax Alphax 3

    Can someone please tell me what size hole I would need to bore for the flange of an Alphax or Betax #3 tens flange. Want the flange to fall into a Sinar board. Thanks so much. At work and cannot get this without help in time to do the job.

    Just measured the OD of a flange on a Betax #3 and got ~53mm. So a 54mm or 55mm hole should work.

    Thanks Darren. Got in a hurry and bored it to 2 1/4" / 57mm after looking at Steve Grimes site (1.98" thread) so should be just right. Again thanks.
