The best system I know of for placing those pesky anchor bolts precisely where the carpenter wants and needs them is the 'Hilti Epoxy Cigar' which is not a demented party favor, but a rather ingenious and inexpensive system that depends only on the carpenter's ability to follow directions; drill the right-sized hole in the right place, put in the stuff, wait the appointed length of time (temperature dependant) and voila; an engineered connection with published values for shear and withdrawal.

I do not sell this system, but I sure have bought a it of them over the years. In metropolitan jurisdictions, Hilti will deliver AND INSTALL, to code and engineering spec. Especially useful in seismic country.
