How many times did she say "cat's head?"
Based on the day I spent photoshopping heads out of pictures of my cat, way too many.
@@Blondihacks Made me want Chinese tonight....lol
Terry Morgan, th-cam.com/video/wOy2QCssTaI/w-d-xo.html
@@Blondihacks those are all heads of your cat? Cool!
Cute kittys
At least 5
LOL... "I always forget I can't rely on my memory."
Mood
Everyday I wonder just what I've forgotten. Problem is all memories feel so complete, apart from that one night in that bar...
Honestly I do that so often it's kind of a problem. I once started my car to let it charge the battery a bit and then went inside intending to come back in a half hour. Then proceeded to completely forget I had done that. 3 days later I went to check on the car and couldn't find my keys. Then remembered, oh shit, I left it running. I found the car entirely out of gas, and the battery so dead it couldn't really light up the dash.
Luckily, the battery recovered.
@@EllaBananas glad it recovered! Was it ever the same after that, though? :-o :)
Ain't that the truth after 70 something...yup.
That little TOT stock change😂😂
7:50 mystery carbide cutting mystery steel well. That kind of make sense.
"Raar Quinn smash" litteraly made me laugh out loud
Ah, Blondihacks.... The place where you'll get a "shame, shame" for giggling because of a finger in a bore, but glance over "pick one of my holes to be the shared hole." And yes, I refuse to grow up. That's what old people do.
Missed it the first time but watched it again after seeing your comment.
KingRatt Okay, so you’re refusing to grow up as well. 😀
One of my holes to be the shared hole, lol.
The finger in the bore hole was funny. Who doesn't have a dirty mind, lol
@@tylerkrug7719 I don't know who doesn't, but it's pretty clear that Quinn is in the does crowd. :D
"An improper mind is a perpetual feast." - Logan Pearsall Smith
10:51 "Eh - No one is ever going to see this. I think this whole internet thing is a fad." LOL
Ask Cliff Stoll about that faddy internet thing. ;)
-=Doug
3 months later, I see it! :D
I bet someone comments on this in 2030.
But wait, there's even more: Sometimes you might need to turn or bore an eccentric feature on both ends of a round bar (say to cam a door against a gasket on both sides with one handle). The cats head gives you a way to support a long piece of round stock and turn those eccentrics...so the cat's head can even be useful with round stock.
Bonus trivia: Another name for a capstan type winch is also "cat's head". A capstan is the style of winch common on boats where the rope wraps around a drum several times, but doesn't accumulate on the winch...so you have to "tail" (cat's tail...see that?) the free end of the rope, which means lightly tensioning it so the capstan maintains friction to pull on the load side. Modern sailing winches have a self-tailing mechanism, so they can be operated with just the one hand on the crank.
The nautical term may be the origin of the machinist term, as both feature a smooth drum.
This "Cathead" example was what I as going to comment on. When I started working in the oilfield in New Mexico (1971), the drilling rigs had catheads that were used as winches to pick up pipe and other heavy equipment up to the rig floor which was usually about 20 to 25 feet off the ground.
Until I saw this, I had no idea why one might need such a thing. I have learned my new thing for the day and also seen a pleasing variety of different cat profile pictures from Sprocket. This was an exceptionally enjoyable video on both fronts. Many thanks.
Indeed never needed that option yet. But now that I know it will come up. First I need to build a steady rest.
“Obtain conscent.” Oh you opened pandora’s box here ! See, it’s already starting. 😉
I see what you did there!
sivalley 😁 Glad somebody did !
I hope you asked Pandora first!
Always lifts my mood when I see a new upload from blondihacks.
Now off to the workshop to make a cat's head.
On your cemented carbide cutters, add a small chip breaker right behind the cutting edge with a small grinder. A die grinder works well with a 2 inch diameter cut-off wheel such as a Dremmel found at most construction boxed stores.
I don’t know if you’ll see this, but as someone who very recently started watching machining videos, thanks for the boring bar camera angle. I finally get what they are!
You are right about too much stock sticking out of the back of the lathe spindle being dangerous . I saw a story recently about a guy who got killed that way because the stock bent at high rpm’s, struck and killed him. The shop had a support device for that purpose but he didn’t use it.
After watching several of your videos, the final nail in the coffin that forced me to subscribe was your lathe buying guide. Have a great day.
I say “as is tradition” every time I face a part now.
These are great for things like a threading operation on a rifle barrel where the bore is off center but the threads have to be concentric with the bore. Dial in a pin gauge in the bore and go to town.
Excellent addition to the lathe arsenal 👍.
I think you need a "Flap Stick" for polishing bores on the lathe, just a bit of round wood, with a diametrical saw cut for a short length on one end, then thread through your choice of abrasive paper.
Great vlog, thanks for sharing.
Best regards from John Quinn.
I love how you share your knowledge, and bring us along the journey
I have 2 cats heads already 😸😸, but I like your design better, less clawing and biting.
and doesn't need a litter box, just throws up the occasional chips...
begs the question, where is the rest of the cat(s)? Is there a recipe involved?
Applied Incompetence the heads are still attached the rest of the cats. This makes them useless for machining, but effective at shredding furniture.
Square, hex, octagonal shapes are even, not odd! Great video. My cats were not harmed during viewing of this episode.
Thank you. Excellent tips. You are "smarter than the average bear" to quote Yogi. Your soft jaws just reminded me of some scrap that I should have thrown away a few years ago and now I probably never will - alumminum mini blind slats. They even have perfect radii so they all nest.
WOODWORKER grade precision???? You do realize that we use KNIVES to mark our work, don't you! You... sharpie using machinist. ;-)
go play with your dead tree carcasses and let the real workers work xD
@@____________6145 Tell me “real worker”, have you ever connected two pieces, that change size on their own in different directions, AND have them stay together? I think NOT! 😉
@@truckguy6666 I use my father’s wooden folding rule. Calipers are for checking drill sizes. Those little “machined” numbers are never visible.
Careful, woodchewers need tools made of metal, made by metalworkers.
Be careful, our profession is addictive. You will be apart of the knives for scribes program.
Every time a cat's head popped up on the screen, I am reminded of "Cat, I'm a kitty cat, and I dance, dance, dance...And I dance, dance, dance."
Quinn, your videos make me happy. I like the image of your cat popping in every time you mentioned cats head!
Indexable carbide parting tools are also your friend. You can run them at very high surface speed and keep cutting pressure fairly low
A very good project for any lathe use. I work at our local community college running the machining lab & have made a couple of these for our bigger lathes to hold smaller stock with the steady rest.
A real steady rest. Not often I see proper steady rests. You defnitely know what you doing.
Always a good watch for the new guy. You are on reconsidering, essential for most newcomers to the lathe. Keep on keeping on. Cheers
Nice project. Love the internal deburring tool
Finally I do understand, thank you Quinn for the subtitles , thank you.
I love that little inside deburing tool.
lastly, the dig on woodworking was hilarious. and your commentary is frikkin funny.
Showing your cats head pictures made me chuckle, TOT's been doing similar when using the word "but" hehehe
Haha, yah I just watched that. I guess we had the same joke idea at the same time.
You are a natural born teacher. Thank you for the great commentary.
Thanks so much for the metrics. I finally understand what you’re doing there!
love the inside deburr tool
A tool that gets the job done and yet simple in design?? Engnr. call that "elegant" ... be still my beating heart
Very clever that inside deburring tool!
Seeing how you show cats on your videos you got my attention. great product thanks.
Once your Cat's Head is running true it should be possible to use the Dial Indicator on the work flats. Then adjust the Grubscrews to true-up the stock.
Your videos are great! thanks for teaching the world!! Muchas gracias.
Now this is how you can clamp down on a pentagon shape.
Right on, Quinn! That's super cool.
Hey Quinn nice cats head, but when you put on the back of the spindle you also add a piece of round tube that fits in both the cats head & the inner bore of the spindle to use it to hold the stock protruding out the back of the lathe. Cheers from Oz
Love your videos and your sense of humour I do believe I’ve found my new hobby ….thanks Quinn 🤠👍
My fav machining channel keep doing what you do.
Us gun smiths use a similar widget on the left end of the headstock mandrel to hold the protruding end of a gun barrel while we work on the business end. We call it a 'spider' usually with 4 screws to centre it up....
I didn't know that tool.. thanx for sharing 👍🤠
A36 is like that. It has pockets of hardness here and there. It is the low end of general purpose steel.
Read about a Cat head in an OLD machining manual, stuck it in my head as "one way of solving that problem someday and impressing someone with my knowledge " and here you go splashing it all over the internet.
Your cat is freaking me out! I think I smoked too much before watching. Okay, I dim the lights, sit back and get comfortable. In and out, ohhh yeah, I like to watch...another great Blondihacks video!
Thank you so much for your videos! Just bought my first lathe and your videos have helped so much!
That’s a helpful tool, thanks for another great video
Cool tool thanks Quinn
Great little project video. I enjoy your channel very much.
Thank you.
I enjoyed that, it is a useful tool indeed. Thank you.
I was just about to make a few of these, when I remembered to check your videos. -Thank you!
Would you please do a series of videos on creating metal drill bits please.
No point telling me not to giggle at 9:08 - I was already giggling at 8:48. I’m a terrible person and I don’t deserve to live. 🥺
At 8:45 I thought it was just me, good to know I am not the only one the internet has damaged.
As soon as anyone picks up something long and round my brain quits operating like normal...
ROFL me too!
The only thing that woulda made that more purr-fect would be a little "meow" added each time. Great stuff, Quinn!
Shaft whip 20:30! Well drillers use spyders every ten feet in turbine irrigation pumps. They last a long time as long as they get lubed, else not so much, then Mike got a whole bucket of "red brass" (bronze) for his scrap pile.
Excellent tool to make. Thanks
These videos are so good.
OMG! Inside deburring tool! That is so hot! Never seen one! Three clicks of thumb up for this one!
Hi Quin. Just doing a series of video's making a Hemingway kit large bore lathe steady. Ideal for steam engine cylinders on a small lathe. Great video by the way. Keep it up.
Regards.
Steve.
Hello from Rocket City Huntsville AL Quinn! Thank you for sharing your knowledge and your great sense of humor. I like your channel very much and love that you're doing collaboration work in the youtube machining community. Cheers!
That's a really nice use of collet blocks.
Gotta have a silver sharpie!! One in every corner of the shop!!
U can polish i.d. using a wooden dowel with a slit at the end and wrap the emery cloth around the dowel.secure with a little hot glue.
U can used water plastic bottle with small hole in cap for coolant to keep part cool. Or used bug spray pump for coolant.small to gallon type.
I drilled holes for pentagonal stock on mine. Haven't had a chance to use them yet.
I may have a go at making one of those. Seems reasonable!
" I was giggling " ,Thanks I needed that !
Another great video, love the comedy.
For better parting, turn the parting tool upside down and run the spindle in reverse. This way the tool can flex away from the work instead of digging in. Make sure the chuck won't unscrew!
I liked your "but wait, there's more!" at the end. :) I was sold before that, but now I'll take two for three easy payments and free shipping please.
Cat's head is a much cooler name than secondary chuck.
You could take a little off the steady rest on the back side where it sits on the bed to get it centered better then match the angle on the front side. I suspect if you check it with some ink, it doesn't match up well.
😂🤣"this whole internet thing is a fad". I love your sense of humor you bring to your videos. Thanks for making videos. Your playlist are right next to Mr. Pete's in my favs.
Well Quinn,they say your never to old to learn. I've never seen that before.👍👍👍
You can use your 6" scale to set the steady rest to the cat head o.d. then the cathead screws to center your work.
I just found this channel a week or so ago, but there really should be more likes!
I love that you speak three languages: English, nerd and machinist. Me, too!
And lousy high school French
Hey Quinn i found something like a 8mm bar with a slot and emery paper the right way in the tail stock or a dedicated tool post holder works amazing either way awesome projects and love your work keep up a great channel and including the mess ups ( yeah we do it) greatly appreciated 👌
Thanks, educational and you have a great personality! :)
I was working on some steel today that was picked from the same steel tree your's in this video came from. I had a steel spaghetti noodle almost 2 feet long when I was drilling it. I have never had one that long before. Good ole' Chinesium.
you all ways have great ideas ty
another awesome video ty. great project
I use both varieties regularly in the gunsmithing world. They are handy. Another application is by the use of shim stock you can hold a threaded feature accurately without damaging threads.
well done 👍 thanks for that tips
You always bring out my inner nerd.
You make comment about how sexy a deburring tool is and in my mind I’m saying “hell yeah it is!!”
Ordered it😒
If I had to guess I'd say that was 4140 HT. I only say that cuz I literally just machined some lol. It had weird hard spots and super hot chips even at a low rpm. Anyroads, thanks for the video! A clever addition to the shop to be sure 👍😊👍.
True fact. Cups of tea were invented to allow steel to cool in the lathe between cuts, when the apprentice loaded up the wrong steel.
another great cool video - thx!
You do nice projects.
Quinn, you are so erudite and entertaining! Machinists rule and your videos continually expand my appreciation for the craft.And how about that! Although frequently involved, it was clear that no cats' heads were harmed in the process of making this video. So what's the etymology of the term? That whole hole thing was a giggle. Cheers from Vancouver.
Nice! I WILL make one - I need the practice - maybe two, one specifically for the t'other end, as shown at the the end (not related) of the video
Great project
I have not yet encountered a reason to need a cats head, but when I do I’ll know what to do. Thanks Quinn.
Another amateur machinist here, love the project, I also have some mystery steel perfect for this. So after using it, do you think it would be more user-friendly to have maybe knurled head socket screws that you could adjust the coarse setting by hand (like thumbscrews with a socket head), and then use the wrench to achieve final tightness? My guess is that if you had enough clearance on either side of your steady rest it would be fine, as they're only put in one side for the back of the spindle arrangement.
