  1. Offer a plate of food to a dog and the dog will think you are God. Offer a plate of food to a cat and the cat will think she is God.
  2. I got the advice I needed and enjoy seeing old-fashioned tools. Anyway, here's my new caliper:
  3. That's a nice looking drill. One of the tragedies of modern manufacturing is that as makers of commoditized goods start cutting corners to lower costs it becomes prohibitively expensive to compete on quality rather than price, so everybody cuts corners. A similar thing happens when new technologies replace old technologies, with the setup costs for manufacturing the old products being way too high to make production profitable given the relatively low demand. It really is a shame.
  4. Who is "still questioning" anything? Like I said, I've ordered a dial caliper and will be using it to measure bridges.
  5. As someone who's never done this before my main concern was whether vernier-style calipers would be suitable for the purpose of measuring bridge thickness: whereas the calipers used in plate thicknessing measure thickness around a small circular area, vernier-style calipers measure the thickest point along a line. Now that I know luthiers often use this latter style of calipers I can use them myself with confidence. Luthiers do love their tools. Looking forward to getting my dial calipers; They satisfy my tool lust.
  6. Went through 200, 1500, 8000, and leather impregnated with 0.5 micron diamond suspension. I did get a burr on the 200 and 1500 stones, and finished on the 8000 and the leather strop.
  7. After final sharpening on an 8000 grit stone and stropping on a piece of leather I have managed to get the knife to cut newsprint and shave hairs, but it's not very effective at cutting wood. I'm giving up for now -- I've spent hours on this -- and look forward to receiving the knife I ordered from John (violins88).
  8. That Starrett caliper looks real nice. I just placed an order for an inexpensive dial caliper on Amazon that has mostly good reviews. It has two needles, one for inches and one for millimeters. I'm tempted to cancel the order and get the Starrett, but I want to give the Amazon one a try. Thanks all for the advice.
  9. Anyway, here's what the knife looks like after grinding away on the 1500 stone. Only some of the edge looks like this (there are high spots along the length of the bevel so I'm not always touching the edge), but I think it's getting better.
  10. This manufacturer says to only grind HSS on these wheels, but it looks like they're making the same mistake of lumping together HSS and other hardened steels. Anyway, your mileage may vary depending on the precise composition and heat treatment of the tool.
  11. Which style of caliper is best for measuring the thickness of a bridge as you slim it down? I expect there's a number of you who do it by eye, but that takes a great deal of experience so what would you recommend for someone new to doing setups: a digital caliper like in the first picture or a thicknessing caliper like in the second picture? The latter is a lot more expensive, but I'd like to get into making once I learn to do setups so I'm going to need one eventually. I know I have a digital caliper somewhere, but I can't seem to find it since a recent move.
  12. On the other hand, these forum posts offer a bit more nuance than "HSS only": https://www.tormek.com/forum/index.php?topic=3252.msg20404#msg20404 https://www.tormek.com/forum/index.php?topic=3461.msg25671#msg25671
  13. I've seen this on websites that sell them, and on this piece from the Arizona Woodturneers Association: http://azwoodturners.org/pages/tips/WhatIsCBN.pdf
  14. I'll give that a try. 1500 stone, using the technique described by Roger Hill.
