New video and blog write up. This one may be especially helpful to machinists because I detail an issue (especially in the blog write up) that I don't think I've ever read about before that can certainly lead to an elusive cause of chatter.

Couple ideas for your issues on the 1/4" tool. Have you tried plunge milling just the corners, then doing the rest of that toolpath? You may also try drilling the corners before you take out the field in your first operation, and plunge mill the corner after drilling. That would have the part kept supported and vibration free when you do those 2 inside corners. Then go on with the rest of the operations as you have done in the video...

Thanks for the suggestions Mike. That's exactly what I'm going to try.

I tried plunge milling the corners and it worked pretty well, much better actually. It was a little tiny bit chattery but I'll play with lowering the RPM a little.
Did you try it in the same order as the video, or before you did the main material removal portion? Would also be best to use a tool with a small corner radius on it, not a sharp square edge...

Yes same as video. Roughed out first with the 3/8 rougher, then plunge milled the corners, then finished profiled with a small radius in the corners to avoid engaging the corners again. Worked great, just need to adjust the rpm down a little.
This endmill has sharp corners but its replacement has a corner radius. I agree that should work better.

New installment. A lot of useful info for aspiring machinists, inventors, product developers, and numb nuts (like myself) in this blog post from hard fought and won experience.

Looks great! Congrats on the bio-machine - I didn't see that option in the list when I got my Mikini!

Ha! It didn't come with the machine it was a parameter setting in the VFD I think. The Mikini just came standard with bio-hazard for a spindle driver. Lol.

Watching at work with sound off. Is that a Harbor Freight bandsaw? Model #? Looks quite capable at cutting thick steel...
BTW, the part looks GREAT! Must be satisfying to see the end result after so much hard work. Hope you do well in sales of these guys!
