Well, I am undecided there and wanted to mount an Assos set I have, but this one will not work with the Zeus spindle. So I might change the whole thing to a Zeus Super cronos drilled set including the original BB-set. With the Assos cranks I have the BB but not the special tool to mount it. I might also use a fitting Zeus Crankset fitting that 118mm spindle if I can find one. I should be pristine, as all parts I use in this special project. I also considered a Superbe Pro crankset i have if I manage to find a fitting BB. So generous offers for these items are gladly considered. I prefer trading cranks or other stuff in this case.

Thanks again for all contributions in this thread.

What crankset are you wishing to install on that frame?

Folks, Thanks for the input and all the hints and tips. Meanwhile I solved the problem. I checked everything again, and as it is a new frame and the campa die I used is also pretty unused, this was not the problem. After running in the tapping die another time I realised it needs a little more force when run in deeper. So I decided to run it in as far as I could in order to make sure even the last threads of the die are cutting. This obviously did the trick, afterwards I could install the cup with ease. It appears that the cutting die due to ist's conical construction cuts better and deeper with the last threads. I have installed the desired Zeus 2000 Titanium BB just to find out it's spindle is to long for my needs, measuring 112mm or so. Does anybody want to trade or has a shorter 107mm spndle for my prokject? It is not that I would not have enough proper spindles around, but not a singe titanium.

I'm with Greg on this one, seems your tap may have become dulled by cutting chromed threads in the past? Your tap isn't cutting it (pun intended).
