For the last week, I've been practicing English Small Scrolls. I've been cutting them with a Lindsay "carbalt" graver shaped to a 115 degree Lindsay "Universal" tip. I was so pleased that the tip remained intact for several days, without even the need for sharpening! I must have cut 60-70 scrolls with this tip. So, last night the tip finally failed. I resharpened it with the same Standard Lindsay templates on the same GRS diamond wheels that I used before and polished the tip on a ceramic wheel with diamond spray. Bam! the tip snapped after 15 secs.! Resharpened again, same result! This went on 3 more times, with one only lasting ONE STRAIGHT CUT before snapping the tip! I'm using the same practice plate, the same settings on my Monarch handpiece etc. I just can't get my mind around what is suddenly changing. Any bright ideas?
Frustrated,
