From the Archives: Cherry Hill interview - Part 2

complete with traditional drawing board, photo 3 on which General Arrangement and component detail drawings are worked up from the often meagre information which can be gleaned about the prototype. Some of the drawings are created at full model size, photo 4 but Cherry prefers to work at ten times full size for most as, at this scale, she finds that she can assess clearances more accurately. One of the workshop rooms is equipped mainly as a machine shop, photo 5 while the other is where most of the hand work and fitting takes place, photos 6 and 7. As mentioned previously, pride of place in the machine shop is still occupied by the Pittler lathe, photos 8,9 and 10 but this is augmented by the latest in a succession of Myfords, this being the Connoisseur version, photos 11 and 12. The largest milling machine in the workshop is a Myford VMC, photo 13 which is capable of dealing with the heaviest work that Cherry is likely to undertake. An addition to the VMC is an inverter drive which allows control of motor speed, a particularly welcome feature, says Cherry, as this obviates the need for frequent changes of drive belt position - not the easiest of exercises on this tall machine.
