The ability to smell what the material is is a cool super power.
I love that you show the brain farts. We all learn from our mistakes (hopefully)! Coming along nicely!
This video has SO MUCH information. I've noticed that the more I learn, the more I know what you are talking about AND what to look for as I see you working. Thank you!
Thanks, Bernie! I appreciate that! 😄
As always, good stuff. I always give a thumbs up (to crush a troll) before watching your videos. Thanks much.
Two things for your consideration: 1. If using a 90 degree spot drill, you can save yourself some deburring by making the spot larger than the through hole by twice what you want as a finished chamfer. 2. On small parts, you can get away without using a hammer to seat them if you listen for a "clack" when placing them in the vise. If you don't hear a "clack", there's some debris between the part and the vise jaws.
You aren’t stupid! You are building your machining experience. It’s definitely a learning curve. Good luck and good machining to you.
I'm glad to see that even the pros forget which way to tighten a chuck by hand without paying close attention. It's a 50/50 chance but it's like a darn USB plug in that I'm always wrong. Also, you rock.
I agree about the Fein. My sister and brother-in-law gave me a Fein vac for Christmas 15 years ago and it is still the best shop vac I have ever had...I currently have 2 and there is no comparison. I have two of those angle block sets (red case) and they always pop loose - sympathy nod. You were using what looked like cold rolled steel which has a lot of built in stresses, so perhaps the slot was smaller because it closed after you milled it to size. Beautiful work.
A 23 min video, published 2 (02!) min ago and already with 6 likes (me included) !!! That is what I call expectation! Will love it for sure.
I did not know the origin of "balls out" before your little insert. Makes a lot of sense now!
"balls to the wall" has the same origin.
Hmm... I can tell this is referring to 12:34, and that shape is familiar, but I don't actually know what it is... what is that mechanism, and what does it control, and how?
@@DavidLindes look up centrifugal governor on Wikipedia. It uses the centrifugal force of spinning balls vs gravity or a spring to limit fuel or air to govern speed
It's like when advocates of gun control use fire arms referenced expressions. And don't even realize it. Flash in the pan, half cocked, lock stock and barrel etc.
@@mpetersen6 I respect guns and know they have their places in society, but I am still an advocate for gun control, but not abolition
Hello Quinn, great to see the end mills being used. On your slot width for the bearing, always keep in mind, industry standard diameter tolerance is +0, -.002 on 1/8" and larger Carbide end mills. If you don't take into account this tolerance it may lead to under size conditions on your part piece. Of coarse you have to be able to measure the end mill diameter, which is not easy for most people. In today's world, tool manufacturers now use laser micrometers. The 3/4" end mill is called a VFP (Variable Face Profile). The curvature of the face changes the shearing potential of the tool and the profile on each flute is staggered from the others. Thus it produces a anti-harmonic response during cutting. Keep up the great work my friend.
Great info, thank you Dennis!
@@Blondihacks Your Welcome my Friend.
Dear present Quinn , Your precision with each video grows greater , your workmanship is outstanding !! I look forward to future Quinns videos ( A Quinn Dunki production) Pete M
Tips:
1 - A powerful (12 Amp) shop vac is an indispensable chip removal tool around a turret mill, especially for short chip faceing cuts.
2- Drill the corners a trife over-size from your clean-up cutter before you slot mill. If you have the option and a sharp corner part mates with the slot, offset the corner hole 0.293 x the drill radius to "bear ear" the corner. Thus, the corner radius circumscribes the sharp corner an internal rectangle with minimum material removal. (0.293 = 1 - SIN 45°) this results in 0.018" over-cut Vs 0.062" over-cut using the "mouse ear" technique (where the drill is centered at the slot rectangle corner.)
You’re my favorite RUclips lady machinist. You splain stuff so us dimbulbs can follow what you’re doin and why you’re doin it. 😎👍👏
Ah yes, the Ebay mystery steel strikes again ! Good to know I am not the only one that happens to! 😉
Great video Quinn I have been a machinist for over thirty years and I still manage to learn something new. Very impressed with your work.
Thank you for adding the metric translation in text. I should be able to calculate myself of course, but on the fly I am not fast enough, so this is great!
Overall very nice project. Just another quick hack for you. When dialing in work on the 4 jaw, you can use a brass or aluminum block between the bed and the jaw to stop each jaw in the same place every time. That will save you having to locate your lowest reading every time. Much quicker. If you still want to double check by oscillating the spindle on the last time around, you can, but most times the block will get you close enough.
Another nice chip clearing option is a vortex tube, blows the chips away and blows VERY COLD air directly on the cutting surfaces.
I am really enjoying watching your excellent videos, great job on the steady rest fingers.
I am really enjoying your excellent comments! Thanks for being here! ☺️
I just wanted to say thank you for your intelligent, funny, and informative videos. My 5-year-old daughter and I love to watch your channel, and I'm so glad she has some excellent female role models plying their trades expertly--she asks for you by name (and is also a big fan of Claire from BA's test kitchen).
That’s awesome! Tell her I say hi! 👋 I’m also a huge fan of Claire at BA. 😀
Just guessing at the mystery metal, possibly SAE 1040/45, other wise known as "Key Steel" ref what looks like 13" length 🤔🤔🤔. Have a look at " Sparks test" for metals, basically using a grinding wheel and interrogation of the sparks.
Great modification, some precision slotting indeed.
Tip, when the part sticks out to high out of the vise, clamp a 1, 2, 3 block or similar resting on the jaw with the part.
Like those extended inner race bearings.
Great vlog, stay Safe all and thanks for sharing.
Great video.
I like how you explained the versatility of the lathe.
Well done. Can’t wait for the next video
After a project like this one looks at a " simple blank " with new appreciation and respect
Love the past, present and future Quinn -- also any theoretical, cloned Quinn's reproduced using an accurate DRO (provided future, utra-smart Quinn is the operator).
Excellent!
Lovely job Quinn,you are a pleasure to watch.👍👍👍
Your sense of humor is great!
Very nicely done!
Quin go to a local counter shop that makes granite counter tops and see if you can get a drop or scrap piece to use for your sanding surface. I got one works great
Great idea!
The picture of the governor literally made me lol. Things like that and the HTML soapbox are great.
Awesome video, love the fact that you never hide the ‘brain farts’ and, as a Brit, the innuendo in this had me in stitches. Not sure if it was deliberate but I hope it was. Keep up the great work.👍
Flame Boy watch the blondehacks “weird set ups” you may have to press pause may times.
I appreciate the “lathe first” soap box because a lathe is all I have and it reminds me how much can actually be made on it (and how) 😁
I'm really enjoying this series. Thanks very much.
I really enjoy your humor and execution.
Loving this series and your approaches to machining. Thanks for sharing.
Thanks for another great video, be safe and stay healthy
Another way to find center and square up a rectangular piece of stock is a way I've watched Adam do. Take the piece and cross scribe the end and center punch it. Then take a round piece of stock, chuck it up and center drill one end and turn the other end down to a point. Now put your rectangular piece in the chuck with the center marked in facing out. Take your round stock and put it between centers so the cone shaped is in the center punch mark of the rectangular piece and the other end in a live center of the tail stock.
Now just put a dial indicator on the round stock and adjust the chuck until the round stock is running centered. An now your rectangular piece is centered. Now just keep the round stock for the next time.
“I am as dumb as I will ever be...” hope you don’t mind if I start using that one at work. Great video and good tip on the lathe setup. Good to know I’m not an average noob for buying a lathe first. I’d give three thumbs if I could.
Thanks Quinn. Another excellent video as always. Stay safe and healthy.
All the best,
Norm in Arizona
Going along very well it certainly looks good. Everyone has their favorite method of doing things.
Thank you for show this. Wunderbar und toll gemacht. Its a good Job.
Never knew soapbox is HTML, learn something new every day!
Love your humor, keep up the great work!
I’m glad anyone got my HTML joke. 😄
Thank you very much Quinn keep making great and amazing videos please! Im always watch your videos with dad ´cause we want to set up our shop. Best reggards from México.
Two thumbs up on the Fein vacuum!I've got the earlier model (bought on discount back when the Turbo I was introduced) and I love it. It's quieter than our home vacuum, and my go-to for the stairs... Built-in slave outlet for a tool is also a nice feature, and quieter than most tools that need dust pickup.
Yes! So great.
Great stuff!!!
Stay awesome, Q
I notice you have the same Grizzly version of the standard 4x6 Chinese bandsaw that I have. I built a coolant tank and splash guard/return system for mine and dropped in a $20 garden fountain pump. A little HDME tubing as delivery hose and couple ball valves turned this little saw Into a metal eater and tripled the blade life. With a 10-14 bimetal blade at the saws fastest speed it will walk thru 3” hot or cold round stock in two minutes. Using it a dozen times a week or so on average to cut every shape and thickness imaginable I get a year out of the blades easily..
Good info, thanks! That 4x6 saw is ubiquitous. Every discount toolmaker has a version of it painted their color.
Now I know why I prefer the mill 😁
enjoyable as always...keep up the good work. and thanx for sharing some good tips
Why do I like your videos before I watch them?
Because you’re awesome. 😬
Why not?
@@Blondihacks Thanks LOL, so are you.
HAHA! Be careful with terms like Puppy Mill, I cracked right up
Excellent narration.
Primo work. Lathe thinking is fascinating.
Great job on those parts!
Always beautiful; I love.
Nice Job quinn.
Finger of Cthulu? Careful, Metallicor might be a jealous god!
Jealous and vengeful, I worry
Be afraid, be very afraid.
Im glad Im not the only one who smells their material. I so need to do this for my 11x26 import lathe.
Now I want an Official Blondihacks Metal Smell Guide
Think Abom did a hack for indicating square parts in the 4 jaw, lay a ruler on the v bed and against the part, then indicate on the rule, you can rotate as if your indicating a round part then, 👌. That "My present self " comments cracked me up 😂😂👍
She’s female version of TOT 😂👌🏻 I love it... if tony was a lady, would have been blondyhack 😂😂
Could it be, This old wife is Blondihacks? *conspiracy music*
Mr Redstoner And if TOT & TOW (BH), had a kid, it would be AVE! 😂
I get the impression that she is much more skilled than tot.
Cool! I'm very glad to see the end result this job! Nice work dude! 👌👍 Greetings from Finland! 🇫🇮🇫🇮🇫🇮
....June 23, 2087. Quinn Dunki releases footage of intro bloopers. While not directly related, this is the day remembered by most as the day the sanitary wars ended. Since then we have advanced to the level where both imperial and metric fist shakes have equal rights in metrology.
Oh gosh, there are so many. Every one of those intros takes about eight takes for some reason. 😅
🤣 Wouldn't pick it from my side of the screen mate, The flawless intro is a weekly highlight.
I extend the usability on larger endmills, 5/8” - 1” dia. to me, by free-hand grinding a small 45° on the burnt/worn tips. Much like sharpening a twist drill. They actually work better than the sharp points for surface milling.
Yah, I’ll be regrinding these one way or another. Good tip!
I use "Hobby Metal Kits" for much of my materials. Thanks for sharing.
For adding a strip of 'pressure foam' to cases; to keep parts from moving (as with your angle blocks), I've been using some melamine foam. It's sold as the 'magic eraser' sponges, because the melamine is remarkably hard for a polymer, so works well in that role. But in this case, it's got good stiffness, springiness and longevity and, important, it's very easy to cut (due to it's stiffness). I use a utility knife, which works great; not quite sure of the feeds and speeds if you wanted to mill it!. EVA foam is similarly easy to cut, but softer and denser, so doesn't work as well for acting as a retaining spring.
A thin stip running the length of the top, position along the middle, will apply the pressure to keep the blocks from moving, and is only a 5 minute job. Working form the stuff sold for cleaning means needing to piece it in, but that's not an issue for this application. The melamine foam is not hydroscopic, so won't keep moisture in there.
Good tip on melamine, thanks!

Regarding the pin for the bearing. On mine, I drilled a full size hole on one ear and a smaller threaded hole on the other. careful to thread the side that will self tighten as the bearing turns. When its all installed, everything is flush.
Do yourself a favour and build a PAIR of keys for the 4 jaw.
Makes all that pushing and pulling go a lot faster when you can wind in from the back as you wind out from the front to hit your dial gauge number.Saves a lot of time rotating the chuck.
Love the video as always.
I just wanted to congratulate you on the well-formed soapbox XML
Productive home/shop quarantine I see......LOL
Wow... A tonne of tips went into this one Quinn! Looks awesome! Sad to see that cutter got burned up though, never great when tools get ruined, although, when I ruin tools its my fault :P in this case you got given some mystery metal, hope you're staying safe, thanks so much for the video!
When you set up the casting to start with if you could have machined several flat faces on the headstock side of the casting that were at right angles to ways surface. If possible drop holes through the surfaces to pass studs through. Then you have a flat surface to reference from.
I have a steady rest, nevertheless it is good to take a look at you improving upon yours. I'll try to upgrade mine as well...
Great work. ✔️💯🏆
Thanks so much for sharing. 😉👌🏼
Your experience and path to the Fein turbo 1 sounds exactly like mine ... best thing ever.
If that vacuum was a person I would marry it.
@@Blondihacks Future project: adding AI to Fein T1 and see where it goes
Niagara sure has crazy looking endmills
So I told, loved it.
For the angle on the pin, you could zero the cutter on the top of the jaw, add the pin .250 + desired wall thickness .100 + %10 for final and surface finish cut .035
Also a small angle plate would work great for the end slots since you can support it standing straight up.
Yah, I do have an angle plate, but that’s fussier to set up than the vise, and I want that internal radius from milling horizontally
Grind an endmill to the corner radius you want, kind of like a semi ball nose. Just giving different options. Theres a million ways to do it.
I really dig your style
Great mods to a previously crappy steady-rest! Mine is 3rd party and suffers from some of the same issues. Nice hack!
Nice work.
Present me is the stupidest I will ever be. -Blondi, 2020
Words for the ages! Love these vids. Very entertaining.
And always amazing what such trial and error leads us to reflect on.
G'day Quinn, You can't say clever things like that and say don't think too much about it. Because that's exactly what happens!
That was very interesting. A self centring 4 jaw is a good investment.
I've got to comment, Caaarrrl.
A scroll self centering 4 jaw chuck is good for round as well as: square, 8,12,16, 20 etc divisible by 4 equal sides.
Not rectangular section.
Not that I Ever have a brain fart...
I am watching these steady rest videos with much interest. Have my own small EMCO 5 lathe and no steady rest. Sure I can buy one for ~50€ but those looks weak, plus how fun is that.
I've never considered using an indicator stand as an end stop. I'll have to remember that one!
You have to be gentle, or the magnet might slide on you, but I find it works very well
You should look into one of those 1.5" carbide insert endmills that are all over eBay....I have one with a 3/4" shank and uses 3x tpg332 inserts....they are like $40 and they work great.....and the tpg inserts are really versatile....
Yes. As Stefan says, there's no place for HSS, even in the home shop.
Another "I need to do this" project. Very nice.
agreed on the Fein - i got one and its great. Why isnt a vac used more often with machining? I get that when you’ve got real hot chips maybe its a fire hazard but mostly you don’t.
There is a reason why woodworkers gravitate towards a mill after we get one.
It is because our drill presses have upset us and pissed us off so many times, we feel the need to prove to ourselves it was the equipment and not us causing the problems.
The part where you don't hold the work by hand and get to move things by the thousandth of an inch is pretty handy, too.
My goto channel for philosophy.
When centering in the four-jaw, try using two chuck keys, opposite each other. Find it so much easier and don't get lost as to which way to move the jaws.
About that filing at the end....
There is a nice new video of Tom Lipton named "Toolmakers Adjustable V Blocks P4" where the second half is only filing...
Two things i learned
1. you can blue and sign a lines which guide you for the chamforing
2 and most usefull - when I file an external radus i always filing wrong, where it shiuld be in the oposit moving direction.
" Once deburred the parts will look sharp". lucky you said look. 😆
i was gonna make a comment on that! Yours will do. :-)
Where's the link to that nail polish? I've been looking through McMaster-Carr to no avail. Keeping it to yourself, aren't you?!
I've pretty much given up on painting my nails. I use my hands too much for any kind of nail polish to last more than a few hours before chipping.
@@EllaBananas you make it hours? :D
@@camillosteuss fair enough. I say sometimes it’s worth the trouble, though. 😄
💅
Got my shop vac doing an "Asset Recovery Sweep" in my 'hood, which is how I also get my project materials- my only problem is trash pickers getting there first; this is a constant problem for us "Asset Recovery Specialists".☺
I was so sad when you didn't say yahtzee after you used the horizontal bandsaw :(
Geez, I knew something was off...
Cool, thaks for the interesting video
I considered the chamfer of the fingers and your reasoning and at first thought I agreed. Then I wondered if the chamfer actually may lead to collection of debris. If the parts were well matched with a close tolerance that a lubricant would fill, it seems less likely that you'd get anything in there.
Inside machined corners are never perfect, so it’s normal practice to clearance the mating part.
