Just wanted to say, worked in job shops over 40 years and just retired, enjoy your content and do see some missteps but don't take that wrong, I've made a thousand of them myself, not just in the beginning but right up to retirement. I've found out something obvious, what seems easy in a full shop like at work is not even close to the challenges you face at home with a modest shop that you've been able to aquire over time. I enjoy your content, research, and ability to admit when you goof up, we all do it! Thanks for all the effort you put into it and keep up the good work! Just sayin.

Nothing better than shop made beans. As for the use of the ring: If the inside diameter was slightly larger than the can of beans, you cover the partially eaten beans with wax paper then slide the ring over the can to re-seal. ! Nice Vid!

Thank you for being so awesome! My next project involves cutting a keyway on the lathe or arbor press, but as a hobby machininist i cant invest in the broach set so, maybe next week you'll have a video on how you made a custom lathe tool post or arbor press keyway cutting jig haha.

Thanks again and I look forward to watching the rest of your great content !

Quality content. Ive been restoring an old lathe that I brought home from the junk. Im now able to turn my first parts and make things for my lathe in order to make it a more complete lathe. I thoroughly enjoy learning from your channel and cant wait until i can perform many of the machining operations you have made so easy to understand.

For the thrifty, there's another benefit to trepanning bean cans. Leave a few metal chips in the sauce and you won't have to pay an oral surgeon for your next gingivectomy.

[@howardosborne8647]

Bi-metal holesaws are also very effective at trepanning in the lathe. Keep cutting fluid on the cut and frequently withdraw to clear the chips from the teeth. The deepest I've cut with this method is around 35mm. Also check out David Wilks channel. He is a master of deep trepanning on a centre lathe.

[@scottwhitcher265]

Ive heated canned soup on a mud pump engine (DD 6-71)manifold many times. When time was short, I made a wire basket to hold the can down the exhaust stack. No vent, unless you like the taste of diesel soot but be sure to not leave it too long! My favorite was an episode of "Home Improvement" where a contruction crew made grilled cheese sandwiches with a propane torch. Gotta use the tools available!

Pro Tip: When having beans for breakfast, don't EVER decide pancakes would be a good side dish. When those sweet Campbell's Brown Sugar Beans first came out my two girls were little. The beans were so sweet, one of them said we could use eat them as lumpy syrup on pancakes. They used to use any excuse they could to get me to make pancakes since I made small, 'silver dollar' pancakes, and typically devolved to all sorts of shapes. Pancakes and brown sugar beans, it is, says I, to a round of cheers. We made them, ate them, and proceeded to toot our appreciation for most of the day, accompanied by much laughter. Mom even got in on the 'symphony', much to the girls delight, (they were used to hearing dad's 'musical' talents.

Now I want to see you make something out of a can using the lathe, from the tooling and jigs to the final item.

[@celestialbeas9214]

So literally all I do at my job is trepanning cast iron. We have an array of trepanning tools that can drill up to 11.25" ID and up to 36" long in a single pass. We can also flip parts to do 72" long things. It's pretty fun. But very noisy. With lots of coolant. We use Warner and swasey, and Gisholt giant hex turret lathes with 28" Chuck's and 12" spindle bores.
