Machining Big Holes in thick stainless custom flanges

- In this video we machine some custom stainless steel flanges for a research project. We trepann the largest hole and step drill the smaller one, we also do a bolt hole pattern in both.

I know there are plenty of CZcamsrs who will always sneer at safety comments, but those dangling hoody laces were giving me the collywobbles.
Old boilermaker recalling old boilermaker methods.
People don't pick their pets, pets pick their people. Cora is a perfect example of this. You guys are a perfect match!
Great Vlog, notice you had your hood string loose using your lathe be careful.
Trepanning is a very good method, leaving you with a very usable blank instead of a few kilos of chips. I used to really enjoy watching David Wilks in the UK, trepanning "canon bores," probably 30 cm in diameter and a couple of meters long, using internal cooling and a dedicated lathe. Good to see that super DoAll drill press! Thanks for another stimulating and entertaining video. Our GSDs Halgrim and Bella send greetings to Cora Lee.
To stop the large drill wanting to 'walk' and stress the Jacobs chuck, use the boring bar to open a counterbore just large enough for the drill lands to enter.
Brings back memories of working at EMS and testing parts used for manufacturing of satellite parts. We used chambers that were 6’ square and had to achieve very low vacuum pressures. They had a number of large holes that plates were made to allow us to get test & power cables in and out for different parts testing. Getting them to seal because of the extreme pressure difference was a challenge. They looked exactly the same as yours but I think the surface was more machined so they could seal. Thank you for the memories 😂
Ahhh drilling, tapping, trepanning and coffee with Steve. Life is good, my friend.
Every work environment needs a good mutt to complete the feel of a business. An strays make the best because they've chosen you.
I am a relatively new to owning a personal lathe but have done some shade tree machinist work be for an been around it most of my life. And I have been helping others with my lathe lately and making a little money at times and nothing supper tight tolerances or anything. but I have never seen a parting blade like that and it will save me a ton of time in the future. because I tend to having a lot of that kind of jobs. and drilling and boring a hole like that sucks on time anyways. LOL even though I still enjoy the time but other things got to get done also. Thank for this video and enjoy your channel.
Steve, you're among the few machinists who seem to regularly run their cuts at sane speeds. I'm amazed at the number of CZcams videos I watch where the machine is screaming at an insane speed. I realize that too low of a speed will destroy a cutter, but I know from experience that reducing the speed allows for a far butter cutting experience. Really appreciate the time & effort I know you put into these videos. Please keep it up & thanks!
Production work! LOVE IT! Knocking em out, gettin those doll hairs.
Hello again from Thailand. Cora just keeps getting sweeter. I don't know if you or she lucked out the most, but either way you two are a glorious match! Thanks for sharing her again in this video.
I still smile at how nice the shop came out after replacing the wall.
I know you have to do what is needed at any phase of your life, but as a long time patron- I’m really glad to see some machining again on this channel. I’ve stuck around because I think you seem like a really phenomenal person- the kind of guy I’d definitely want to be friends with- but I’ve really enjoyed your machining content the most.
Great show.
Another interesting video Steve. Thank you. Glad to know Cora has settled in well. Her turning up in need of TLC was meant to be. You have both gained and benefitted from her adopting you!
That was a nice change of pace for the shop. Happy Thanksgiving!
I have done smaller stainless pipe flanges with annular cutters in the lathe, I have up to 64mm dia cutters. Works well, better than boring it out.
Hope everything's OK!
