Update on a post Carlos (thanks brother :bow put up a while a go about a source for inexpensive carbide engravers from centennial carbide.
I purchased the “ultra micrograin†1/8†and normal “micrograin†blanks and ground them to a 3/32†square for use in my Lindsay. Thus far, they work pretty well and I'm quietly impressed. It is definitely worth a try for under $2/graver.
I’ve not done any knife blades (hardened steel) but thus far they are worth the investment.
For those with a Lindsay, and wanting to know "how"..... I simply made a jig with a Jacobs chuck with some square stock bolted into the back to index the round stock consistently. I then ground away w/a 80 grit diamond wheel and progressively measured as I ground w/ a calipers. It was tedious but less than ~3-5 min / graver. They are now dead on and fit great. If you do this, don’t forget dust mitigation and control the heat when grinding.
Thus far, I've made square and 105 deg, and I'm going to try some flats tonight.
Want to ask if anyone else has tried and/or cut anything significant w/ these?
