Hi All, I'm new to this list and have been asked to do this bio as a right of passage. My name is Lawrie Silverberg. I am a 51 year old follicularly and estrogenally challenged person ( I prefer the days when I was a bald male). I live in the country north-west of Toronto Ontario, in Canada (the hell of the used tool world as another member has described it). When not at home with my wife and the dogs, I'm probably in my dental office telling people that I won't hurt them. I have only been woodworking for about 1 1/2 years and don't specialize in anything specific at this time. I've mainly been making things for my shop as practice for the more sophisticated work that I hope to do. Actually I have made a nice frame and panel stand for a statue. I have a TS, BS, ROS, and router (sorry) but get my greatest pleasure from using my hand tools, which I use as often as possible. Right now I'm making a storage unit for my tools and am cutting 208 dovetails by hand. Hopefully I'll know how to do it by the time I'm done. |

Hi Steve, Thanks for the welcome. I'm surprised that I'm the only dentist here, as I've met a number on the net. Woodworking is a "natural" for us as it's not very different from what we do all day. > After a >second or two of being surprised and wondering what on earth dentists have >to do with files, I then remembered that they're quite the common and >important dentistry tool. (It was obvious, after all, only I hadn't ever >really thought about that before.) If you ever come across this paper I'd love to see it. The instruments we call files and rasps have nothing in common with woodworking files and rasps. Dental ones are cutting instruments used in root canal. They are round, and tapered to a fine point towards the end. Stainless steel files are made by twisting a square wire. The corners of the wire are the cutting edges. You insert the file into the canal and file the sides of the canal by pulling the file up. Rasps are very similar (I don't use them as they have a greater tendancy to break) but have more of a conical shape. The newer nickel-titanium files are more flexible and are cut out of the wire as oposed to twisted. The latest instrument of torture on the market is the rotary nickel titanium files. Interestingly, the ywork like planes and shave the walls of the canal as they rotate. The closest thing we have to a wood file or rasp is the diamond drills that we use. They abrade like a file (I know some people refer to a file as cutting but we make a distiction in that a diamond drill abrades as opposed to a carbide drill which cuts). If you ever pass through Brampton, Ont., I'd love to give you a personal demonstration :-) Lawrie > >Am I being silly, or is it really something folks in dentistry do get >into in that much detail? We don't usually discuss this type of thing at dinner parties :-). I just happened to have taken a course recently on the new rotary intruments. |

Hi, Lawrie. Welcome to a great bunch of galoots. :-) I think you may be the first dentist on the list. Well, you see, I've got this chip over here outta this bicuspid, and ... oops, sorry, forgot my manners there for a moment. :-) Say, seriously though, I do have a question, in light of your profession. Doing some reading up last year on files and rasps, I came across some really good info in a technical paper that went into the technical aspects of the cutting-tooth geometry of files and their various cutting characteristics, and really got down into the nitty-gritty of it all. It was a really, really good paper. (But I don't remember the source, though; it's been a while.) But about halfway through reading it and being fascinated by the info it offered about files and how they work and the different types of tooth shapes and how that effects their cutting, I was startled to find out that the paper had been written not by some technos in a school or in a file factory R&D department somewhere, but by a couple of dentists! After a second or two of being surprised and wondering what on earth dentists have to do with files, I then remembered that they're quite the common and important dentistry tool. (It was obvious, after all, only I hadn't ever really thought about that before.) So anyway, I don't know where I'm going with all this rambling, but I thought of that connection between files and dentists when I read where you said you "don't specialize in anything specific at this time" [meaning woodworking], and I thought, well, yes, maybe you could tell us all sorts of things about files we hadn't known? Am I being silly, or is it really something folks in dentistry do get into in that much detail? In any case, now that I've made a fool of myself in front of everybody (nothing new there) being so pesky, again, welcome to the group. The guys here really are amazing and good folks. -- Steve |
