Blades

[savethebeer]

Did this Friday night and Saturday morning. Its going in Damien's bar in his house for his retirement pressie (its a surprise so don't tell him). I have to add in a firefighter helmet and something else, and then shape it into a fancy plaque, then back it and stain it. 

Its 6mm BB. Did the S in Damien's with a Pegas 5 modified geometry. Face looked good but the back was rough so I changed to a Pegas # 3 reverse skip. Cut about 20 letters, and went off to bed. Next morning cut about 10 letters and then the blade broke. Over the next 2 letters, 3 # 3 blades broke. Changed back to the original # 5 blade and finished it without any problem.

1st # 3 broke because the top slipped from the clamp and the blade bent at the bottom before I could stop the motor, but I don't know why the next 3 broke. It  certainly brings on bad language.

Picture won't open for me eas well. But Pegas blade breakage, I use Pegas modified very good blade but sometimes several will break for no obvious reason.

Thank You for not posting the bad language that you used.

By any chance do you have some of those Pegas blades that had the notch cut in them at the top? There are still thousands of them out there. I had some breakage too but then I learned that if I clamped the blades higher with the notch right under the clamp screw, no more breakage and there was still enough reverse teeth at the bottom that I got a clean underside cut.
