Thanks for taking the time to put together your videos. The machining you do and the materials you are working with are a lot different than what I am doing on a daily basis. It is always nice to see different methods and try to learn something new from someone who has many years experience.

The mighty Inconel 718. That big beautiful hunk of it weighs as much as my whole lathe, and undoubtedly costs 20 times as much too. I bet your fork lift gets a work out. :)

At the end of the video i only then thought about the obvious question. What are these parts mainly used for. As you seem to do the similar sized work, of similar types of material. Thanks for the video. Regards Peter.

Trepanning is a 20mm cut so a massive force trying to "lift" the job. Always the top bearing which breaks. The pad is a type of nylon which doesn't break 😉👍

Hi Chris. Total time was approximately 14 hours. There's no way to speed this steel up it's running the fastest rpm it will take. 👍

Hi Tim.. the pad I use instead of a top bearing is a type of nylon called "polypenco" the top bearing takes the most force and is the one that breaks.

There is 5mm difference so approximately 2 - 3mm clearance around the tool. Even less the core through the inside of the tool.

718 is particularly difficult due to its relatively high content of niobium and tantalum; makes it very strong even at high temperatures, but challenging to work with.
