My registration slipped a bit. Not perfect by any stance, but this might be “good enough” to use while I attempt it again. Milling acrylic makes my work area look like I just got about 3” of fresh powder. It was also my fist time to try flame polishing. Still have to cut the Brush part. Hopefully I get it right the 1st time and only have to cut the top again. Attachment Deleted  |

Good work. I've used flame polishing quite a bit. Works really well especially if you sand the edges to 600 first.
Lol at the "snow". I feel the exact same way when I was prototyping my dust shoe from white HDPE.

Oh, and what did you end up using for your speeds and feeds?

Oh, and what did you end up using for your speeds and feeds? I was agressive. Speed was around 20,000 RPM and Feed varied between 1800 and 2200 mm per min and a plunge rate of 200 mm at 3 mm passes with a 1/8” single flute up cut end mill. Probably should make my step over a bit smaller. I’m still new but at least I didn’t melt it this time. I think the single flute was the biggest part of it all. |

Evacuates chips much more efficiently. But moving quick helps a ton. It's all about keeping that perfect chip load. |
