No, this looks like the correct pair.
I had the same issue when I first started making gravers. I couldn't figure out why the heels were not running parallel with the angle. If I recall....I think I was using too much downward pressure when grinding the angles?? Try regrinding the 96 degree...
Also, when I first started to make gravers, I was using round HSS. I would grind the angles then add the heel.
Based upon a 96 degree graver....The 96 degree angle that I put the heel on was not quite 96 degrees. As a result the heel did not run parallel with the angle.
I had to go back and...
I like to find alternative methods also. Visit my Instagram page. #metalbadassery
I tried various materials like welding tungsten, allen keys, various drill bits, etc.... for making micro gravers.
I use micro gravers exclusively now instead of traditional gravers!
Update:
I contacted Amsoil and provided them with the SJ-27 specifications.
Here is their response:
"If it is an ISO 46 and you are not using it for medical purposes then our Synthetic Compressor Oil ISO46 SAE 20, product code PCI, could be used as it is compatible with ester based compressor...
I found this thread after I completed a exhaustive cross reference.
I came up with Amsoil Synthetic Compressor Oil - ISO 46, SAE 20. Compatible with PAO, ester- and petroleum-based compressor oils. (Not compatible with glycol- or silicone-based oils).
The Jun-Air SJ-27 is ISO Grade 46 SAE20 and...
I'm sort of new to engraving also. I have roughly 80 hours behind me. (I live in Canada)
I went to a local sheet metal company and had them cut 200 pieces 1-3/4" square...I don't know the gauge...but they are roughly 3/16" thick mild steel.
These cost $40. They over ran production...so I had...
I just stumbled upon this thread.
(I just started engraving a couple months ago)
I use an HP inkjet printer and print images to inkjet transparencies.
The Prismacolor marker is used to coat the surface of the metal before placing the transparency image to the metal...then burnish the...
