  1. It appears that it is a constant 160 graduations per revolution, approx. 51 unit diameter. Could it be a traveler wheel in millimeters & fractional inches? 6.29 diameter? So hard to tell from the photo... intriguing. I ignored the strange, repeating "betwixt" numerals, but they seem to fall in patterns every 10 units, digits 1-8 only though. Maybe an octal to binary translator....
  2. Did you intend to type "no more than 1/3"...? Just my two shillings, try to pickup some old 3/8 & 1/2" pawn-shop bits & practice regrinding & drilling mild steel. When you can refurbish them reliably, get some split-point cobalts, run them slow & watch how they cut in different materials. Cutter grinding is a useful skill in itself.
  3. I like it. The chain edging should prevent chisels & whatnot from vibrating off the shelf; still lets the grime & filings be brushed out. If it's welded solid at alternating links, you may wind up using it for handy twisting holes on small stock. Consider that little gem stolen.
  4. Do you happen to have that original image or source? I'd like to have it color printed on mylar for my shop. It would greatly reduce some of my explanations.
  5. Engineering manager in aerospace composites with tool fab department and equipment/facility maintenance duties too. Keeps the days interesting. I was very lucky to start my professional career as a summer coop tool design/mfg engineer in '80. A couple years after graduation, I inherited the tool fab shop & machine maintenance, Lots of one-off, blacksmith solutions to keep "unique" production equipment running. My grandpa got me interested in smithing almost fifty years ago; I still use some of HIS grandfather's tongs. top/hardy tools and a small 1# straight pein (very sentimental about that one). My son is an engineer now & we enjoy building prototype stuff for work & repair projects for friends on evenings/weekends.
  6. Wife will love that. Thanks for the verification on the files. Good to see I'm not the only one to find the awesome that is Brownell's
  7. All John's adverbs. Very striking. Did you use checkering files on the handle?
  8. Ditto here. Looking to make one for my maintenance shop for occasional use and I foresee having to "store" the prototype at home.
  9. Good to see you back! I seem to recall a common work interest in fair sized airplanes...?
  10. Less than $2/lb for the pair? Great score
  11. Armadillos are excellent...grilled
  12. 1981Eagle , that is a slick elegant design. Nicely done! If you are able (work stuff) Kozzy , please do post your paper in blueprints or the member gallery or somewhere. Sounds like interesting reading I might recommend to a young engineer I know....
  13. This is why I shouldn't read at my desk during lunch. Took half of break to clean up the snorted/spit coffee.
  14. Was going to ask, but you beat me to it. My lad always asks me, trust me, not a "get" ,it's an honor to be asked.
  15. I duplicated my branding iron from high school welding into a couple of touchmarks from old allen wrenches. Straightened/annealed in kitty litter for the mill/file work then re-hardened. Work a treat. The small one (1/4" hex) I cut with an .06 ball-end and filed the last details with needle files. The 1/2" I used a 1/8 BE mill to dykem lines . No CNC, just cut to a line & filed. Test-driven in alum plate to verify the finished mark. A few trys to get the edge geometry; finally settled on an 80-90 degree on the business edge & they've held up for a few hundred uses. As Glenn mentioned, a bottom index keeps you from fumbling. A grind across the held end for bottom naturally lines up in your thumb pad.
