One of the most informative video on end mill sharpening I think I’ve ever seen, thank you so much.

Very interesting and informative. I appreciate how you describe what you are doing, why, and how, rather than just doing it. I am learning! Lovin your T&C videos.. Your videographer is doing a great job! Close ups when needed.

I purchased an Astra Elite AR5-E a few years ago and have watched a lot of videos and gotten pretty proficient on it. However i never knew how to do center grinding endmills, i certainly do now. Thank you. Would love a video on dovetail cutters. Not many videos on that and thee are quite a few angles to consider. Thank you again, subscribed.

I just realized that I have a dull dovetail cutter. Thanks for the great idea. I'll put it on the list

if you tap a grinding wheel lightly with something it should ring. if not its cracked.

Imagine if you could generate the helix for any cutter without having to use the finger rest to guide the cutter.......I'm working on a design that I thought up some years ago.

Hello, just wondering why you have it so the direction of the wheel direction will raise a burr of the cutting edge ?

@Lappemountainliving 17 күн бұрын

You're right that it causes a bigger burr I do it this way because the cutting force of the wheel forces the tooth face down onto the pointer. By rotating the wheel the other way the cutting force would be trying to lift the tooth face off of the pointer which would result in the wheel digging deeper into the side of the end mill, which would result in more cutting force and could lead to a crash where the cutting force is so great that you lose control. This would destroy the end mill and possibly cause the grinding wheel to come loose and go scooting off across the shop. I find that dealing with the bigger burr is the lesser of two evils.

What is the reason for not using air in the air bearing?

@Lappemountainliving Ай бұрын

I don't use air any more because when I did it would always get "sticky" usually in the middle of a cut. I've always got the best results by keeping it nice and oily. And thanks for watching
