Hey Guys, Go check out this latest video by This Old Tony.

It ain't what you do it, it's the way what you do it.

I've had those problems - love the advice backed up by results in a demo (with predictions)... can't wait to try your ideas - thanks mightily from Sydney Australia

It would be intresting if you made a video about how to cut gears.

One of the most educational machining videos on youtube! Keep it coming! 😀👍

A wealth of knowledge

Interesting that the plastic chipped roughly at regular intervals on the first pass

Instead of a chamfer could you get away with using a radius tool?

Shear angle depends on tensile strength of the material... e.g Mild steel will be completely different to 4130

Acrylic.....otherwise known as exploding stinky stuff

Sheared flat stock is always a dimensional problem and the thicker is the worse it gets. ( Rolled edge / burred edge)

Thanks Again Joe, I've got a job coming up that I'm glad I watched this to learn a new trick.

As always, good advice. Just a question, how much does vibration from the vice overhang affect the finish, and do you have a 'rule of thumb' as to how much height overhang vs thickness is acceptable. I can get problems with melting, you don't seem to have this problem, mine is probably blunting of the cutter, any advice? thanks Tony

I am not sure which is more amazing your knowledge or your willingness to teach us. Thank you

Not exactly. but it is about 1/3 shear and 2/3 exploded

Not exactly but 1/3 shear and 2/3 explode.

Great shop knowledge! Thanks for making my parts much smoother Joe! 👍

Wow!

As always, that was incredibly insightful and useful. Thanks again Joe.

Had an acrylic project for some time, but wanted to wait until I learned how to do it chip free. THANKS JOE!
