I should mention that the granny is larger than 74BCD, which would have placed the holes IMO too close to the 50.4BCD holes.
I had a church member hand it off to a machinist in his company to do the work. The counter sinking was minimal so the chainring bolts do not sit as flush as normal, but I'm not complaining.

My Web site is redclovercomponents.com. It's not functioning yet--I'm still working on making sure the whole e-commerce setup works as it's supposed to. I hope to actually be selling stuff by November 1.
Jon, I'll be gald to send the TA Triplizer for the prototype. It looks better than the Merz, which does not use a 74BCD for the granny.
