I love working with cast iron, but it sure does make a mess. Also, I could have saved a lot of money and cutting time had I known these blanks would show up 30% thicker than spec!

Can all those chips be used to make a sort of "conglomerate" with resin, if you need counterweights?

Well, blast. I have everything ready to go for the first full attempt at cutting a labyrinth waffle plate through "indirect CNC". But the first step is slotting it with a 1/8" end mill, and the smallest collet I have for the cutting side of the pantograph is 3/16". I'll need to order some 1/8" end mills with a larger shank in order to proceed. Blast! I was really hoping to get at least one cut this weekend. I can at least prep the other blank tomorrow, but, you know... blast.

Made a lot of progress today, but it's still far from done. Cutting the chamfers with a tapered end mill just isn't working any more as the sides approach complete. Too much chatter, and my RPM control is very limited. I think I might have to try doing this with a more classic die sinking approach, with a full 3D template to work from instead of just the 2D slot. I could print one easily enough, and it would let me explore some of the other features of the pantograph. But I should sleep on it first. Or just sleep.

Okay, after a very enjoyable bike ride home from the shop through deserted streets, upon which I saw *nine* bunnies, I think I know what I'll do. I can do another layer-by-layer pass with calculated depths using the ball endmills I have, and see if that helps. I think I even have ones on hand in the same sizes I was slotting with, and if not, I can at least confirm that the idea works with just one or two before ordering new ones.

Did you get the idea from the bunnies?

@GustavinoBevilacqua From the way they're always running out into my path, you'd certainly think they had some ideas they really wanted to share.
