We are not happy with the limits imposed by you in the 1" bore, but we agree that such close limits would be necessary if the rollers were manufactured as per your sub paragraph (a), and since your last visit here, and discussions with Commdr. Matravers, he has designed a new type of grinding fixture, which is as per Blue print 960 herewith. We think you will find the scheme perfectly clear, the fixture being bolted to a spigot of the machine, 3 pegs locating in the track of the rollers.
