Hey everyone, yes, obviously it was a typo that I said 4” is 25mm. Rest assured the quality control department has been shown the door once again. I went down there the other day and it was all screaming chimpanzees. Why did I even hire them?
They work for peanuts.
@@stefantrethan their union rep will go bananas if there's evidence of cheap labour.
Ah, but wait long enough and the Chimps will write the works of Shakespeare out for you. Or you could just watch the plays ...... Seriously, thanks for this, it was interesting and useful. BobUK.
Nice video. Nice touch, especially with the over hang and large diameter on a mini lathe. 👍😎
Yeah, I don't see how they missed such an easy conversion. Now I can understand if they were converting say, feet to psi. Heck, I bet even a smart gal like Quinn the Magician has to double-check her math on that one!
I barely remember the formula for determining the modulus of elasticity of a bushel of apples. Pretty sure it has something to do with euros and pounds. Or is it yen and yang? Yahtzee and a tomato sandwich?
"You need to see those pictures like you need a hole in your head." That's amazing.
The moment she said this line I remembered, and I fell down laughing.
I offer you that gag as evidence that Quinn writes jokes just for me and my mildly eccentric sense of ha-ha.
You beat me to it Jon.
Jim's videos except you're not the only one. I admit, I didn't get much past 1:37 before googling, just in time to get the joke. :)
Lifehack: Use a vertical lathe to open canned goods.
humor of TOT, madness of AVE and the weird affection to canned food of Atomic shrimp.
And all of that in the opening...
Awsome!
Best machining intro ever.
That's an instant classic.
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.
“Hole in the head” joke was very cerebral. lol
That went right over my head.
@@ronaldmorrison2765 For me it went in one ear and out the other...
"Dialing-in my beans..." I love it! Waiting for the tutorial on using a lathe to shell a hard-boiled egg, and lunch will be all set!
And peel an orange.
Quinn's little "baby lathe" is doing just fine...
Machine's only as good as its operator...
Freeze your cans, or leave them outside to freeze. Reduces the chuck dismount rush.
Use a live center to hold the lid in place?
❤Loved it quinn, you make me smile often while watching your videos.
Yep definately an entertainment component to your delivery of good solid content.
Thanks quinn I appreciate your work 👍😊
How to brighten up a dull English evening! Love it!
We would heated beanie Winnies on the exhaust manifolds of frac pumps just remember to vent the can! Thanks for sharing.
As a person who knew about trepanning before I got a lathe, I appreciated your joke :)
Enjoyable and satisfying. Learned new things today. Many thanks!
Gday Quinn, very well explained, now I have a new lathe with more rigidity I might have to grind up some tools I think, thank you very much Quinn, one of my favourite channels, always something to learn, take care, cheers Matty
Great set of episodes. Good to lurn refresh skills 👌
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.
"Rotabroach" type cutters even better (quick vid on my channel :) )
Great little video, I have a little project I'm going to give it a go on, thank you
Groovy episode!
I see what you did there. 😬
Can’t wait to try
Very cool. Thanks for the demo
One day, not so far in the future, there'll will be carbide tips printers... And everybody will be happy!
Hi Blondihacks. B & M are my favorite beans. They are really good mixed with scrambled eggs. You really do great work. Your humor is great. I laugh a lot. Best regards.
Just a few days ago I used a large dia hole saw (good quality carbide tipped) for the same purpose just happened to have it available. Worked great. Very quick alternative If you happen to have one
I never really thought about trepanning on the lathe.
Brilliant!
And...Mmm...beans...
Thanks, and Meow to Sprocket.
You ABSOLUTELY read my mind! I was literally just wondering how to preform an operation like this for a project I've been working on. You, as always, are an invaluable source of great information. 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.
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. Moving right along, those chips might remove any pesky polyps in your colon.
Seriously, great work! Loved the mini-tutorial on cutter grinding.
Hi ! I just finished your Lathe skills series , and I must say wow ! Your videos a awesome. I've watched countless youtube videos on machining , and found yours to be the most help full for the hobbyist. I find your videos are very informative , detailed , well laid out ,and easy to understand . The information here has filled in years of trials and errors I've made with my little lathe . Thanks again and I look forward to watching the rest of your great content !
Nice channel and nice video as ever
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!
Great tip and time saver. Just trepanned a 4.5” hole in a 5.375” x .750” billet of aluminium. Machine half way through then turned billet and machined from the other side. No great pile of swarf just a nice billet to use on another job. Thanks for the tip and keep em coming. Not sure you method of opening cans is that efficient though.
Watch that tool pressure! This is no time to put the beans to it! LOL Great "how to" video, Thanks!
Squaring up the tool post with the tail stock was a great trick. I’ll be sure to remember that for the future.
nice video! thanks for sharing!
Great work, thanks for the video. I would like to point out that when opening a can a sharp roller is better than a trepanning tool as you don't get chips in your beans.
That’s iron content. Good for the blood.
Lifehack: Use a vertical lathe to open canned goods.
@@BedsitBob No, a milling machine spins the tooling. A vertical lathe spins the work and has fixed tooling.
@@madmat2001 also much more efficient to spill the beans... almost like spin coating
A good can opener is so hard to find!
Or freeze the can first, cheaper alternative.
The obvious solution is to buy a vertical boring machine
Hey Quinn,
Great video! Now I have the confidence to relieve that awful headache I have.....
All the best,
Tom
May want to use a steady for that job.
Great video!!
This is a nifty technique!
And as a bonus you have an excellent asparagus-peeler 😃 Great video - thank you.
Fresh lathe owner here. Been on a lathe skills binge and just finished this last video. Thank you for making this series Quinn!
Also cool factoid about skull trepanation: there are skulls we've dug up that show the owners survived three sequential trepanations long enough for the bones to regrow as much as they do, and we don't really know how they managed to prevent infection.
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.
To accompany your trepanning of haricot beans, what about milling the top off of a milk bottle, used to be trick on glass bottles with crimped steel caps.
Great vlog Quinn, thanks for sharing.
nice work 😀👍
I love the way you explain every process in what you do. Thank you Blondihacks.
How nice to see clean neat hands in an engineering video. Oily gnarled hands with broken nails are the norm.
I Love to work with 2024 this material is amazing and even heatthreatment is in the homeshop possible 2024-0 for easy machinig and tham hardening to the t3 state and get strengh like mild steel
Thanks Quinn
Idea: the "support my work" text at 11:14 wobbles horrifically until a tailstock comes in from the right and steadies it.
Well done.
If you want to see some Abom plus trepanning, check out David Wilks - boring through inconell, or through a 70 inch steel bar
Now I want to see you make something out of a can using the lathe, from the tooling and jigs to the final item.
David Wilks on RUclips has some mean trepanning equipment and a lot of videos doing deep hole trepanning, I'd recommend giving him a watch.
So my GF asked me to cook more, I now know that I definitely need a lathe for that!
Given the title, I was thinking this was going to be a safety video about not leaving the key in the chuck. I'm glad it wasn't!
gory details of trepanning? neat, didn't know Tom did such things
Perfect , thank you
There's an English guy David Wilks who also makes frequent video primarily around a Trepanning Production job shop. Stuff much bigger and has some excellent videos for those interested.
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.
At first glance, I thought that was a can of Alpo. Kept waiting on a Great Dane to come lopeing on set. Was flabergasted when you took a bite!
I have yet to trepan, but I have used hole saws to cut large holes while saving material. Obviously, I select a saw which is undersized as they are not the most precise tool (at least the ones I have) and use a boring bar to get the final dimension.
Cool beans 😋 I didn’t see it said anywhere in the comments, but I gave up after 2 minutes of looking.
Thank you for this video! I just completed my first successful trepanning cut. Took the center 5" out of a 8" piece of steel. Once I watched your tool grinding about 4 times I finally got it right and it went great!
ok that intro was brilliant
Hey Quinn, I enjoy your tool grinding. I always pick up more from you than other you tubers
Great stuff Quinn. I don’t know why I expected to see beans in your coffee cup ad but ..
I was thinking you were going for a Halloween themed video here, lol.
Very nice.
Your intro puts a WHOLE new perspective on beans & chips (UK chips not US!) for tea! 🤔😲🙄🤣🤣🤣
ewwww beans that havent been faced? you sure you could put up with that taste? hahaha awesome intro and great video Quinn!
This was odd, as I knew the surgical term of trepanning, so I was very curious how you would accomplish that with a lathe. Glad it ended up being metal surgery.
Add a stirrer on a cordless drill and you have my normal cooking routine there.
Thanks for another nice lathe trick :-)
One question though: why do you grind clearance on the inside side of the tool? The inside radius should provide plenty clearance, and not grinding on that side would leave more support for the cutting edge. Do I overlook something?
The tighter the radius, the less that matters, but on larger circles the approach angle approaches zero there.
Love you blondie keep doing what you do .
Best intro yet!
1:45 nice. I thought that’s what I was going to see here. I may watch this anyway.
nice touch with the beans - the only appropriate brand of beans for the model engineering enthusiast. There's also B&M canned bread, which is not nearly as difficult to catch, but you do have to flip the can in the chuck to get both ends off, and heaven help you if your bread is not concentric.
It’s very difficult to find concentric bread. They don’t make it like they used to.
This episode brought to you by B&M. Putting beans in your mayHam. XD
My last job before I finally found a place to rest in the shade and use the crotchety old guy voice I'd been practicing (hey you kids, get oo of my lawwwwwwwn) I had to regularly do face cuts in stainless steel machine parts to update the parts to match the current design in use. These were on centrifuges used in waste water facilities. All feeds were done with the compound set parallel to the axis of the spindle. You have more control over the feed rate and depth this way.
I had to look it up. Challenge accepted!
Very cool
I knew you couldn't go without the jazz hands again.
I'm wondering if opening a can of beans featured in the development of the vertical lathe? Also, did you freeze the can to thwart gravity when the job was done?
Wonderful intro to the link to Tom's video! Stefan G has a more prosaic demonstration, and NYCNC shows the extremes that are possible with trepanning.
See David Wilks for extreme trepanning
Tom IS amazing:) So are you. Beans too
Quinn, if you want to see someone doing some really hardcore trepanning on some fancy metals, then you need to check out David Wilks channel. He is from Sheffield, UK, and most of his current videos are from when he was running his own business. He now works for one of the firms that bought several of his large lathes. He has some work coming up trepanning some large round bars of something exotic and they are 4.5 metres long. He also has a couple of videos showing how he makes his large trepanning tools. Like I said, it's hardcore.
love your sense of humor, you are so much fun to watch....cheers....Paul
i really like how you include metric equivalents
On the subject of the steam engine. Will you do the Clishay watertube boiler with propane burner to run the engine?
look up Dave Wilks channel for Trepanning in extremes.
yeah, his lathe work with trepanning is incredible, I'm pretty sure he's said a lot of it is done for the oil industry.
@@mrcamelpmw Gas industry. They want to get as much gas out from under the North Sea to heat and power the UK as is possible.
I like to make my trepanning tools with an offset, that way when Im doing a series of washers, I can just go right down the part without the toolpost getting in the way, c
Kind of looks like a bent finger. The only down side is you have to make an opposite “finger” parting tool since you have to move the toolpost off square, once you have both tools ground, they save a ton of time, and yes material
So pleased you take your videos seriously. And not doing flippant stunts for effect like others do. 😀😁😂😂
Cannot believe I did not think of using the tail stock for squaring up tools!!!
Thank you for that one. 😎
Actually the classic definition of trepanning is whole-ly appropriate to Holloween and Day of the Dead. Tis the season. Also good for motorcycle club paraphenalia. Won't see beans on Clickspring, either. Another fun video.
Been watching John Mills again have you?
Cooking with Blondihacks would be an awesome second channel.
Just few days ago I wanted to use it to cut larger holes (round 38 mm) in a rectangular steel plate....but a circular hole saw won the race ;-).
As usual, great "show". Tom was good too. Thanks for the education as well as, dare I say, entertainment. (You have a fun delievery...)
Uses a hole saw in the mill. A great way to make custom fender washers. Tho thankyou for the alternative on trepanning
Here I thought the aluminum ring was for the spacer ring you need for the flywheel pulley mount. Give me more time and I will think up something else as well.
The hole saw method is great if you don't need a lot of precision or a great finish. Hole saws pretty much never run true and can leave a bit of a ragged finish - which is fine for many applications!
For the first several seconds I thought I was seeing another youtube ad, and then I saw the lathe chuck. Awesome.
Blondi, you should use the slitting saw on the mill and make some cheese slices to go with the beans.
