I've been runnin' em on my new shonky for about a month now, haven't had any problems yet, will talk to him and see how much he wants to sell a set for if you want?

Got a similar problem. Just brought a frame with spanish bb and a full parts kit separate with Howitzer bb & crank. Do you have any pictures of want your mate has put together?

Just pop the bearings out of the threaded bb shell, and press them in the frame, they should be the same diameter.

Mate- yes same diameter, but the Saint crank uses a fixed spindle which is far wider than a standard 68mm BB- which will be the width of any BB with a Spanish fitting! You can't just pop out the bearings and shove them into a Spanish bracket without the support of an external BB! Hence the reason threaded MTB BB and cranks are designed to have external bearings. Putting a Saint crank into a 68mm Spanish bracket will not work... you have zero support for the spindle which will sit at least 1cm too wide each side. This is not rocket science... the list goes on
