Imperial measures mean more difficult to use
on 6 October 2016
Have only used it for a few cannons and found the American measures a pain. Having to convert every material used in the descriptions to metric, then buying the nearest metric equivalent not knowing whether that will mess up your funal cannon or not, is a barrier to using it on more occasions. Of the 3 tried none have worked as well as it says in the book. This I guess, is as much to do with my total lack of engineering and hands on experience than the book itself. Would have given more stars if they'd bothered to "translate" it into British English and measures.
