Re: Shop calculators and references

Tim,

My workshop 'Bible' is Screw Threads and Twist Drills by Ian Bradley, published by MAP, it covers imperial and metric. From a quick Google it appears to be out of print, but Amazon have it http://www.amazon.com/Screw-Threads-Twist-Drills-Bradley/dp/0852423578/ref=tmm_pap_title_0/185-8900005-4070913, and it is available as a pdf here http://nitrodownloads.net/search/SCREW+THREADS+AND+TWIST+DRILLS+IAN+BRADLEY.
