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, ruclips.net/video/wOy2QCssTaI/видео.html
@@Blondihacks those are all heads of your cat? Cool!
Cute kittys
At least 5
That little TOT stock change😂😂
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.
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.
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

Always lifts my mood when I see a new upload from blondihacks.
Now off to the workshop to make a cat's head.
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...
Applied Incompetence the heads are still attached the rest of the cats. This makes them useless for machining, but effective at shredding furniture.
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 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!
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.
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.
Nice project. Love the internal deburring tool
"Raar Quinn smash" litteraly made me laugh out loud
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.
Be careful, our profession is addictive. You will be apart of the knives for scribes program.
@@truckguy6666 My calipers can get splinters out of skin, would love to see you do that with a tape measure.
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
You are a natural born teacher. Thank you for the great commentary.
lastly, the dig on woodworking was hilarious. and your commentary is frikkin funny.
That’s a helpful tool, thanks for another great video
Love your videos and your sense of humour I do believe I’ve found my new hobby ….thanks Quinn 🤠👍
Seeing how you show cats on your videos you got my attention. great product thanks.
Right on, Quinn! That's super cool.
Always a good watch for the new guy. You are on reconsidering, essential for most newcomers to the lathe. Keep on keeping on. Cheers
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.
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.
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....
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 👍😊👍.
Your videos are great! thanks for teaching the world!! Muchas gracias.
I say “as is tradition” every time I face a part now.
I just found this channel a week or so ago, but there really should be more likes!
I was just about to make a few of these, when I remembered to check your videos. -Thank you!
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. 🥺
As soon as anyone picks up something long and round my brain quits operating like normal...
ROFL me too!
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.
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.
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.
Excellent tool to make. Thanks
That's a really nice use of collet blocks.
My fav machining channel keep doing what you do.
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.
Thank you so much for your videos! Just bought my first lathe and your videos have helped so much!
" I was giggling " ,Thanks I needed that !
Well Quinn,they say your never to old to learn. I've never seen that before.👍👍👍
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."
Would you please do a series of videos on creating metal drill bits please.
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!
Now this is how you can clamp down on a pentagon shape.
nice to see how it is supposed to be done, when i got started i would take deep sockets (6 and 12 point) that would fit the part, cut or bore the square end , cut a nice groove in the middle that fit my steady rest rollers(locks it in place) then you can easily slide the setup anywhere on the material you want. if it is too loose- coke can shims.
yeah, i know it is kinda hokey but i made a lot of parts that way.
That’s actually a really good idea 😄
@@Blondihacks thank you, it was all i could come up with at the time- each one still sets on its little wooden peg
Another great video, love the comedy.
YES! Carbide!
They said this day would never come
These videos are so good.
Slick little unit.
Sprocket!
I inherited a lathe and tooling from my dad. There was an odd piece of metal that he'd made, one of several, and I'd figured out what most of them were, but not this one. This video just showed me what it's for.
Quinn, switch your parting tool to operate upside down and part in reverse. Works great because any flex lifts the blade out of the cut rather than forcing it into it.
Cat's head is a much cooler name than secondary chuck.
The cat's head, the calipers, and the bluing are all hints.
I drilled holes for pentagonal stock on mine. Haven't had a chance to use them yet.
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.
Awesome! Side note....your cat cross eyed? Cute! Lol.
LOL good eye (pardon the pun). Yes she is. Not everyone notices that but I think it’s hilarious and adorable.
Blondihacks hahahahaha. Agree!
At 12:57 "obtain consent" 😂
Great tip.thanks
I have not yet encountered a reason to need a cats head, but when I do I’ll know what to do. Thanks Quinn.
you all ways have great ideas ty
Ooh, don't diss the woodworkers! :)
You crack me up. How do you keep your hands so clean and girly? Half way through an operation like this my hands would look like I just replaced the clutch in a 79 Chevette.
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
another great cool video - thx!
You had me at "abstraction".
Neat project. That's really handy!
Okay, so we have lathe dogs and cat heads. Are there other animal thingies in Blondihacks World? Perhaps crosshead moose eyes, or endmill wombat covens?
Just wondering.
Thanks and Meow to Sprocket.
And a brief Woof for lathe dogs everywhere.
There's rat tail files for starters
well done 👍 thanks for that tips
Great project
Thanks, educational and you have a great personality! :)
Quinn, I enjoy your presentations. Perhaps I have a tip to repay you. Then again, what I believe I am seeing may only be an artifact of your editing. . . Keyed chucks have three holes, yet one sees that most people tighten the chuck using one hole. Tightening using the three holes secures bits so they have less of a tendency to spin and end up marred.
I have found this channel through a comment on Abom79. Very good I'm also a software person with machining and welding as a hobby. I wish I had the discipline to film and then edit things I do, it's a lot or work. I'm doing a project that I believe is novel and interesting, but I just take a picture or two every once in a while :(
I want the back-side of my holes deburred. :O
have you considered coolant? car window washer pump and container could be a easy and cheap way to do that?
I watched a lot of your videos but need to watch videos from before I subscribed so I clicked on this because I wanted to see what she means by a cat's head. When I think of a cathead I think of the timber you cat an anchor to on a ship using the old stock type anchors.
Hey, neat! I didn't know the torque loss for brushless DC motors at low speed was from MOSFET switching efficiency. Huh.
Nice Tip thanks!!
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.
When you hog out,
when you make shims,
you ain't seen nuthin' like the mighty Quinn!
you could have used it to force the brass square to be concentric to the square surface, no?
5:37 Better get a brush to wipe the chips, that helps avoid scratches because you're not rubbing them across the ways. (At least it *feels* better at any rate.)
10:53 "I think this whole Internet thing is a fad" , I got a good chuckle out of that one. :-)
If you want to have some good chip breaking inserts for that carbide tool i have had good luck with TCGT21.51 inserts (assuming that is the tool i think it is). They are for aluminum, but i found they worked well for steel as well when i had my 9x20 sheldon. They really make up for a "less" rigid machine.
that internal de-burring tool was very cool, never seen it so you solved one of those mysteries...yet for this catshead is it a de-purring tool. ...hmmm - ok...not that good but I tried :-D
Awesome, another great project that results in another useful tool, thanks, Quinn!
Just one question, in the end, when you put the center hole on the square stock before the Cat's head is on, if you acknowledge the runout of the stock. So the hole on the square stock is not centered and also it isn't running true inside the Cat's head. Is there a way one could have it run true inside the cat's head and therefore have the features on the end perfectly concentric?
I assume that would go against the stock's bend?
As a machinist, one will on occasion, have to turn some square or hex stock with features on it, and may well do so while in a "cat's head", if the four jaw doesn't fulfill the need, and if one needed a bore to run concentric with the outer dimensions, centering the stock in the "cat's head" would be necessary.
"Lets make a cats head" Great some metal art(silly me) Never knew what it was, but now I need one.
Your cat is cute.
When it comes to Chamfers. ya just can't cut corners [This Old Tony]
I'm not a machinist and my problem was explaining that I was making deadcats for my hobby.
Magnificent!
I always found it easier to dial indicate the face of the cat head first.. That way you are not fighting a wobbling cat head as you try ti indicate in the OD.. Especially with larger cat heads.. Just a thought.. I love your channel.. Very inuteresting.
Well, it might be obvious for some, but if you want to protect the material without using the Al shims (when mounting the 😺) you can find in various places grub screws with plastic ends. Awesome work!
Dammit, you just had to bust out that cool Noga tool, didn't you :), after your last vid on it, I spent ages tracking them down, then thought, duh!, I have a lathe, over the intervening weeks, I've managed to keep myself occupied on other projects, but there you go, flaunting that damn internal deburrer again ;), pretty sure I have some 12mm Ti round bar stashed.....
Another great vid, thanks, Quinn,
Scott.
Have you tried cutting a 'chip breaker' groove in the tool steel bit(s)?
the material is c45 mild steel
I want some gnomes with needle files!
There’s an English guy making huge trepanning tools on here somewhere, he makes giant ones of those. Looks handy.
Very nice ,I like the good movie
Brilliant.
