Shrub,you say no-one challenges you when your wrong so you dont learn, well I was asked to pass this lesson on to you ( dont shoot the mesenger).
Shrub - actually what you have written is slander - however I accept your later retraction. I do not have access to this site as I fail to meet the posting criterea - and the ritual slagging off of posts is not my thing - help or shut up, that's my motto.
The book was 5 years in research and took hundreds of hours to write, hence the cost. The old book by my hero Francis Butter was my inspiration. The update is taking just as long.
Your not being able to name parts from old locks is a sign of the times and in fact bullet warded locks are still made by many today.
Should you be trading as a locksmith then verbal and written communication with fellow locksmiths and suppliers- Some of your posts are very informative but are difficult to understand by your poor terminology - maybe more time in research and less ridiculing fellow members would be a great use of your time.
Back to my book its was updated from a 50 year old copy and was up to date when published - the termonology is now accepted as the industry standard.
