The piece covers various types of drills as well as the more technical reamers and broaches.
This sort of basic description is something that magazines need to do occasionally. Not every time as that would get dull, but every so often try and plug the gaps in peoples knowledge. Basic tool use isn't taught in schools any more and even if it was, the education system doesn't seem to think it's job is to teach anything useful so you aren't going to pick up any model making skills there !
Of course I could claim that the article was written with altruism in mind but the truth is that I had thought November would have been "Detail a ViTrains Diesel" month but Editor Mike decided to use two articles from me in October so I had to put something together quickly for a deadline. Plan A - Silver Fox Shunter took longer than expected so Plan B - The hole article was preferred as all I had to do was photograph stuff from the tool box.
The result is, in my opinion, not bad. It's certainly different from much of the normal magazine fare.
