The best teacher I've ever met told me one thing:
If you don't try to do anything, you'll never make a mistake ... but you'll never do anything.
If you don't make mistakes by trying you won't learn anything.
If you are ashamed of your mistakes and don't show them to others, they won't learn anything.
I found another good teacher.
I'm 73 years young . If I would have had access to u tub and People like you and Mr.Peat my life's work would have taken a different path. Keep showing ALL of the build good and bad it is a learning experience for you and use. Thank you for the videos!! Bill
Lmao mr. Peat
I watch Doublecayn he is really good
I do hope you meant "CZcams". Access to her tub would be...
@@scottwillis5434 Well I apologize for ruffling your spelling feathers. But you got my drift . So whats the harm?
You did just fine my friend. Thanks for sharing your thoughts. 😊🌎✨
I had an apprentice from the West Indies. Part of putting a machine together was taking it apart taking pictures measuring everything and reassembly. He couldn’t say DEPTH he called it the DEATH MIC. He’s now a journeyman millwright and they will always be known as the Death mic when I work with him
as a beginner, this video scares the crap out of me! Especially with the stainless... however, I despite loving the design, I might just go in from the other side all the way through the clamping thread hole and use 4140. Thank you for pushing the envelope Quinn, its has so many lessons baked in! Quality bolts? Never imagined this, lessons learned.
Although you didn't do it here, I was reminded that maybe I should hate you some. I find myself saying "Yahtzee!" a lot when cutting off parts! 😊😊
Many years ago I was working on a project with a large very expensive 316SS weldment. We need to drill two small holes at a strange place. So we machined a fixture to for drilling with a hand drill. We started drilling and it would not cut. Now after seeing your video I realize what happened. That was probably 30 years ago. We bought a carbide bit and it cut like butter. Thanks for the great videos.
I learned some stuff again. Thanks.
Good to see the hacksaw, builds character!
Thanks Quinn, I never knew that you should use splitting saws full depth. Useful tool.
Well done Quinn 👍😎👍. Finally - a CZcams machinist who explains and demonstrates that in most instances slitting saws should be used at full depth. Thank you. Joel.....
They always wobble, meaning only a few teeth are cutting. I tried to make a "almost" perfect arbor, still wobbles. I bound one up trying to cut SS, shattered like glass.
Besides your technical aptitude I just love the way you talk!!
I know I keep mentioning my (late) step-father since he was one of the finest machine shop teachers I've ever known, and when you mentioned air hoses in your shop, it really rang a bell with me. Pop never had an air hose anywhere near his machines in his classroom/shop. He capped off all the air lines but ONE and that one air hose was off in a corner. All the machines were cleaned with brushes... just like you're doing. I also like your filing left handed at the lathe instead of reaching over the chuck. Everyone does it and it makes me crazy to see it.
Loved watching this. First thing I ever made on my lathe when I got it (apart from a couple of plastic bits) was a replacement rod for the side of the second-hand crib I'd bought for my second child. It was a 900mm long, 6mm diameter (3ft by 1/4inch, roughly) rod with a knurled knob on one end and threaded M6 on the other... in 303 stainless. Oooh boy did I learn a lot! Proud of that part.
This Brit apprentice very much appreciates the metric conversions 😊
And this anti-Imperialist American does as well!
@@DavidLindes Uh... K 🤨
Add a touch of anti-seize to the screw. SS is terrible for galling
Good tip!
@@Blondihacks 2nd this, stainless really does have a habit of piling up with dry fasteners. It would be a shame for your wicked cool vise stop to meet such an undeserving fate. Thanks for the stellar content
Doubly important for NPT and other tapered connections. I’ve lightly hand screwed SS NPT fittings before and have them gall up on me so bad I ended up having get the torch out to get them apart. Double trouble because the hoses were custom order items with a 5wk lead time.
Vacuum grease and PTFE paste work well in addition to your standard anti-seizes.
Or use a stainless screw...
@@fredgenius not quite. Mating threaded components of the same alloy - especially stainless - are more prone to galling. A 304 stainless bolt with a 400 series stainless threaded hole will be better than a 304 with a 304, but you should always use a sufficient thread lubricant with stainless fasteners whether they are being installed in like or dissimilar material
Quinn, I used the Anchor lube today on some 304 SS. Turned, drilled, tapped and parted off 2 pieces with no funky smell or smoke. Thanks for the tip!
When I was an intern in a physics lab many years ago, among my responsibilities was to drill little vacuum relief holes through those stainless steel optical shafts. I did this in a machine shop surrounded by half a dozen professional machinists none on whom ever told me anything about work hardening or anchor lube or the importance of being right in center. Arrrrrrgh. Anyway, thanks to Quinn, now I know!
I love your scrap drawer!
As soon as you said you were going to use stainless for the first time, I knew there was going to be trouble. The very first machining job I ever did was on 316 stainless - little did I know!
After burning out several drills I asked some friends in my model engineering club (i.e. real machinists) what was I doing wrong? After all I was using Tap Magic (Loctite!?!) and getting the feed and spindle rates correct and I got the best piece of advice I have ever had.
"Never let the bastard stop cutting."
This gave me an idea on how to improve my homemade carriage stop that I use on my lathe! Thank you Blondihacks!
69 youngster here, hobby machinist with PM25 PM1127 and PM833.
But I have worked in few machine shops as electronic control engineer (Sensors, instruments, controls programming PLCs etc) May I suggest a few tips and tricks that I have learned over the years?
Set screws: get a piece of copper wire from say 2/16, 2/14, 2/12 etc... I keep just a few inches of the ground wire in various guauges.
Now whenever I have to install a setscrew, I ALWAYS put a short cut piece of wire in the whole before inserting the set screw. This way you will never mar a shaft, a keyway etc
A millwright I met was using BBs for air carbine and pistol!
Never had a problem getting a pulley off a shaft after this trick!
Super glue: once the parts you want to glue are absolutely free of grease, even finger grease, wipe them with a damp cloth and dip the part in baking soda powder (it used to be a cow on the box, now it's a strong man.... you know what I am talking about),
Put the parts together and drop the superglue at the joint. Use the thinner type.
The physic behind this is that superglue will bind each baking soda grains to each other and to the surface, augmenting very much the actual surface contact. It's at the microscopic level but believe me it works!
Also, you can fill a hole with layers of soda and superglue then drill and tap into this to repair a damaged screw thread. This work very well in cast iron!
Keep those good VDO comming! I learn a lot from you...
Luc
Oh on ss 303 ,304 i use peanut oil for tapping was an old machinist told me about it plus if it smoke it make the shop smell better than old cutting oil
Great build. I find a vise stop to be an absolute necessity.
Neat trick with the glue on the Allen wrench.
I’m just glad it worked. 😅
@@Blondihacks Me too, fishing that fastener out otherwise would have been its own video!
Seriously, I love that you say, "real machinists" as if you aren't one. Great work.
A very pleasant watch. Thanks for that. I appreciate your references to Stefan G. and including the various foibles of the process that we all encounter. I've learned to make some extra blanks when I'm puttering at things so I can have a do-over.
I've learned several things from you already. Keep up the great videos and thanks again.
That's a neat little tool.
Good video too, of course!
And thank you for knocking off the vibration gauge. It was frustrating.
Thanks, and Meow to Sprocket.
Great video, thanks.
A better way to attached the ball: ball should be smaller than the bar in diameter.
with a common drill bit (same dia. as the ball), drill a hole 3/4 ball's diameter deep. Clean parts for oil free, and pour few drops of locktite ( I used 270). drop the ball in, and bend the "lip" around towards the center with a small hammer. rigidity is guaranteed. when I did mine, I used 5mm ball and 6 mm bar. (sorry for my English)
thanks again.
Gotta love the weekend uploads. Love the video, always a handy tool to have in any shop.
Enjoyed watching you do this project with your typical expertise and humor. Thanks for the video.
Cool project. To get it to work with the collet block try putting a parallel between the block and the vise, perhaps this will allow the stop rod to contact the corner of the block.
I learn at least three things every time I watch one of these videos!
Channel some Robin and silver solder those bearings on and you're golden. Great work!
Good video. A tiny bit of silver solder under the ball would work, and best of all be permanent. Gotta make one of these.
Nice work Quinn!
In case you're interested: A little trick I learned for tapping stainless is to actually drill the hole 0.1mm bigger than needed. Gives the tap a little more room
Awesome stuff.
Tip: cover your air blower with a rag and you can really hook in without blowing stuff all over the place.
Try to always cut against the fixed jaw. Not such a problem with light cuts but one day it'll push hard enough to dislodge the part. Haha.
You do such a great job explaining things to those that might not know anything about machining. Explaining what a vise stop is would have never even crossed my mind because It's so common to me that I don't realize others might not know!
Like me... I didn't know about vise stops... I use one on my metal band saw... & A stop on my radial arm wood saw.
Hi Quinn,
Good to see one being made for stainless... I like the slitting saw tip... Thank you.
Take care
Paul,,
Because chamfers just make the world a better place. Quinn August 2020 -- soon to be a common saying.
Hi Quinn. I love your videos. I didn't know that cutting would work harden a material, but it makes sense in retrospect.
Could always run a triangle file down the inside right angle to remove the fillet :) Love the vids! Keep up the content and I’m looking forward to the next steam engine vid
Could not the fillet tend to round the vice edge?
Hi Quinn, nice job! If you try a V2.0, stop rods with a dog-leg are very handy, this way they can swivel up or down to suit your job or obstructions. And a Cam Lock lever could also help - threadlock the bolt in to save your threads and adjust the cam lever for clamping pressure. It'll make it a lot quicker to operate. Stay safe and well :)
All good ideas!
Great little project, well done!
Always love to watch you work!
The split line does not need to call perfectly on the end of the thread, you could simply overshoot the through hole a bit. So long as the thread is anywhere to the right of the slit, you're golden
I see a radius turning tool in your future !
Use Loktite 609 instead. Samo-samo but WILL "usually" hold ANYTHING together without a precise fit! I used for or five drops on an anvil, and just set a cheap hand axe heed on it. Two days later we broke the axe head, using a 20,000 lb hydraulic press to get them apart! Never did get ALL that axehead off.
Try heat or solvents?
love to watch you work wish i had half of your tools i have to use my drill press and a cheap cross feed vice, but i only do very minor and coarse milling around the farm. great vid BH
A suggestion.
Never use 6-32 of you can help it.
This is the most often broken tap because the threads are too course for the diameter. 6-40 always a better choice.
agree on 6-32 being a poor choice of thread. 6-40 isn't common in my hardware stash, so I would have chosen 8-32 or M4
@@grumpyoldman5368
If you don't have 6-40 screws in your stash, I suggest getting some. A lot easier than dealing with broken taps and broken screws.
In electronics 6-32 is one of the most common sizes, so I had to learn to work with it. I agree that it's problematic, but if one is careful, success usually obtains. It helps to cheat a little by going up a thousandths or so on drill size as holding power requirements are frequently lower, and the extra clearance helps prevent seizing the tap. And just work carefully.
But i agree that there are better choices if they are available to you.
You got a like for the full depth cutting info on the slitting saw. Thanks
I would give you a second like if I could for the superglue Allen wrench trick
Thanks CZcams algorithm! Great video! This feels like This Old Tony mixed with Emily Graslie from The Brain Scoop. I look forward to watching the rest of your videos!
To make the collet block set up better, turn another rod that is milled away (or offset turned) for slightly more than the length of the collet nut. Easy peasy! An L-shaped rod that can go down into the vise is also useful.
Totally agree on the anti-seize for stainless--I use Tef-Gel which is sold in boat shops. It's super sticky-goopy but clear and teflon-based. Neither screw needs to come out very far, so you won't notice the messy anti-seize.
Good tip on the slitting saw !👍🇺🇸
Hi Quinn watched this vid last night, after lunch today I wandered out to the man cave and made one very similar. My vice has only got liiiiiitle up stands so I could no do the drill through bit. But your clear instructions on how to do the operations helped mine work just so. Thanks from the UK
Nice piece.
Made a similar one but with a threaded bolt for adjusting.
its 4am after a long day of screwing around with the 3d printer and the lathe, and lo and behold as I go to turn the comp off, new blondihacks video!! All you dang creators overseas pick the perfect time to upload dont you? :P haha
Great work and teaching skills!
Like other(s) I too didn't know to use slitting saws full depth so thank you for that. I was, however, told by an exert to always cut a dovetail in one pass. You first machine the trench for which I use tipped tooling on the mill and run it as fast as possible and watch the blue chips fly. Then run through with the HSS dovetail cutter going much slower than theory would dictate and very slow feed with plenty of coolant (to both cool and to flush chips away). Of course you need to plan this cut very carefully to ensure that you end up 'on size', but I have had great success with this technique and the quality of the finish was spectacular compared agaist my expectations.
Such a beautiful design! (Nice build, too.)
Very good project, well explained and with your usual humour . Thank you
Hey Quinn. Good vid as always. I’m a newbie and your vids have been informative. Appreciate it. Just a tip... to attach ball to your rod. Put the ball on the tip of a drill Chuck with NO LUBE. Put the rod in your Chuck and press the two together with a fair amount of force. Spin it around 600 and increase the pressure slowly. Instant friction weld. Just watch carefully and the second the bearing spins at the same rate as the stock... stop the late. Works like a charm!
I like the big blue door stop you have hanging behind the mill.
Maybe put the rod in the bit grinder to round it?
She wanted to use a ball bearing because it is hardened and perfectly round.
Use Copper grease on all threads when using stainless.
It seizes up before you know it.
I'm watching the whole thing before I comment ...well done! Love it! 😁
Cheers
Great video!!!!! I learn a lot from you!!! Brass tipped set screws,,, you can just drop in a little bit of brass rod into the hole ahead of the set screw,, or copper.
Great video I love it........ oh wait I have to watch it first😉 but I know it will be funny and great
That green stuff is said to be made for stainless because it won't attack the micro structure of the steel I quit using that green snot 40 years ago. No good as far as tapping fluid. At home I use molydee for tapping but very expensive . Mostly I use Used ATF. for cutting oil
Excellent video, very educational and fun too!
Thoughts about retaining the ball bearing (some duplicates other posts):
1. Grind off some of the polished chrome from the surfaces you will be gluing or soldering / brazing; roughen the surface a bit
2. Drill out the end of the rod, put in a ball bearing, crimp or peen
3. Silver solder or braze
And @George Mann Sr. suggested using a (I assume valve) pushrod from a gasoline engine. Gas engines come in many different sizes; might talk to mechanics and to small engine repair places. I'd think you would want a diameter you can find under/over reamers for.
I wonder if for fixing the ball bearings a Liion battery spot welder might do the job? For a totally clean fix it would require an external trigger button (usually a simple soldering job) as you would want the ball being firmly contacted while being pressed firmly to the hemispherical indent.
A soft copper sheet insulated from a vice at the back face and connected to the anode and the bar insulated from the vice also but connected firmly to the cathode. Once happy with the set up a couple of short pulses might well give an even more solid fixing than CA glue.
Just a thought.
You had far to much fun playing with sliding bits with this project. 😀
My mind started working out a single screw method for holding the rod, and clamping the stop to the vise. I like the looks of this. Very...... svelte.
Good shop organization.
AvE sent me. She be one badass metal maker. And Blondihacks is skilled too. 🛠⚒️🧰💪
It is wonderful, and you too
You are good! Excellent reaching.
very nice vice stop good job i always learn somthing from you. keep up the great videos. thanks.
literally made one yesterday! what a coincidence.
Thanks for sharing!
NICE WORK.
A bit of shim between the clamp and the stop body would help the collet problem. Just enough to bypass the ring.
Nice video on a really useful part, I have made one some years ago but always follow your channel. However, ref going ful depth first time on slitting saws is new to me! (you can always learn something can't you?), tried it and well, bang on!
Thanks for the tip.
THANK YOU...for sharing. Very much enjoyed.
Nice little project, Quinn 👍😊👍.
Only today have I found your channel. It’s nearly perfect - a great voice giving practical info.
One thing I’ve noticed over the years is an attitude that sneers at making things for yourself. Indeed, the shops I’ve been in have been 100% CNC, and what little “traditional “ equipment was covered in dust and lacking in fixtures.
Open thread holes saves nerves.
Nice job. We posted this video on our homemade tools forum this week :)
Thanks for sharing that. I am going to make one myself.
Great vid Quinn. You can slit your flexture hole offcenter. If you put it tangent to the bore you’d gain a few threads.
Good point!
Loved it all but the BB's.
you could use a small ball bearings in a shallow hole and swag the end to retain it.
Perhaps another idea for the design would be to use something like a setscrew to hold the small rod in place? Add a flat to the small rod for bonus marks?
For sure! That would work well, I think
Loved it, thanks
I'm not sure if you're talking about machining stainless or the morning bathroom rotation.
Cobalt drills work excellent in stainless.
A completely different approach compared to This Old Tony but just as pleasant to watch.
That was great, you very good at sharing info, I learned a lot
Great video!
Stainless isn't too bad, I work with enough Inconel to enjoy stainless of all flavors :)
Keep up the good work and cheers from Cleveland Ohio.
Quinn, I just stumbled on your CZcams videos. Great and enjoyable. I cheat sometimes on making tooling.....IE, I wonder if an old push rod from an engine valve train would work for a balled end rod? Has a ball on one end at least. Just a thought? I realize it's all about producing these parts on our own. Anywho, thanks for the videos!
Hi Quinn,
Congratulations are in order! In my books anyway. You’re one of the first I see to use a thread tap properly. By that, I mean rotating it back to break off the chips. So many I see just wind the poor tap in the whole way. I was taught many years ago, and was to the point of wondering if modern thread taps are different! :)
Love the show. Rx
Failing to break the chips, especially for small taps, provides feedback VERY quickly. Hopefully one learns from it (or gets instructions before).
While making optical mounts, I stumbled on a simple, reliable method to capture a ball bearing in a rod or screw. Basically, you use a twist drill to bore a hole slightly deeper than the radius of the ball bearing. You then raise the lathe tool above center and use it to fold the rim over. Basically ‘peening’ the edge & folding it onto the ball bearing.
A little geometry tells us that the drill depth to the center of the ball is:
Depth = R / cos( 90 - alpha/2 )
R = ball bearing radius
Alpha = drill angle {135, 115, 90,….}
This has the benefit of allowing the ball to move relative to the rod or screw.
It is certainly worth a try…..
"... As you can see, it's clearly 1 thou over size." Clearly. Of course.
😬
Sounds like someone didn't pay enough for their bionic implants!
