Tioga max Flow 1 piece crank/BB question

[animal]

When I fit the above crank with a  standard PPP Power disc . Then fit it in a standard US BB on my MRD's with either a Tange sealed BB or Tange Beartrap . There is not enough thread left 2 fit the lock nuts  All bearings r fitted correctly and can't c that the power disc is overly thick  Anybody else had this problem ?

had exactly the same problem with a yst sealed bb and a takagi crank mate. thought i was going nuts. tried  different cranks (tioga & sugino) and it all went together fine  have my takagi's fitted with tioga bb's and they fit fine bizarre man??
