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 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.
Well done Quinn 👍😎👍. Finally - a RUclips 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.
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
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!
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.
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.
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.
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!
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.
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
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.
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.
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
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.
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
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!
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.
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
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.
@@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.
@@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
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.
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
Thanks RUclips 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!
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 :)
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.
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
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
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?
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.
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.
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
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.
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
I know this is an older video but someone might find this useful. When I need to custom size bolts on the grinder, I chuck the head up in my cordless drill and run the drill as I grind the bolt. This keeps it fairly even and you can make a quick, clean chamfer by angling the drill when you are done so the bolt starts easily.
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…..
You are such a happy machinist! Wheee... Aside from that, I learned how remove a set screw that gets stuck. Thanks. I could have saved alot of time if i knew that trick awhile ago.
Silver soldering (plumber's solder) or silver brazing? Soft soldering would be fine but the high temp of brazing would draw the hardness from the balls. And the plating on the balls may be resistant to solder.
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
The biggest problem sith galling comes from when both parts are made from the same alloy. The problem can be reduced or eliminated by using another grade of SS, or carbon steel, brass, etc for the bolt. Lube or ant-seize is still recommended.
You might want to look into purchasing a shell mill for surfacing. They are fantastic and give you a wonderful surface finish. Also they are not very expensive for sizes up to about 2 inches. A 2 inch one will run around $50, which includes inserts.
I didn’t think the three threads were going to work. You pulled it off! You know you’re gonna have to solder those balls on. I have to get a Scotch brite wheel. I enjoyed the video.
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.
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.

AvE sent me. She be one badass metal maker. And Blondihacks is skilled too. 🛠⚒️🧰💪
303 is free machining 304 ,316, 321 etc non hardening . What happens when you dwell with your drill, is you friction weld your hss drill with the stainless that is why it becomes hard . Some kind of alloy.
Quinn, I just stumbled on your RUclips 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!

Because chamfers just make the world a better place. Quinn August 2020 -- soon to be a common saying.
Nice job. We posted this video on our homemade tools forum this week :)
I know this is an older video but someone might find this useful. When I need to custom size bolts on the grinder, I chuck the head up in my cordless drill and run the drill as I grind the bolt. This keeps it fairly even and you can make a quick, clean chamfer by angling the drill when you are done so the bolt starts easily.
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…..
Great video I love it........ oh wait I have to watch it first😉 but I know it will be funny and great
I'm watching the whole thing before I comment ...well done! Love it! 😁
Cheers
You are such a happy machinist! Wheee... Aside from that, I learned how remove a set screw that gets stuck. Thanks. I could have saved alot of time if i knew that trick awhile ago.
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.
literally made one yesterday! what a coincidence.
Good tip on the slitting saw !👍🇺🇸
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.
You did a good job. I would consider Silver Sauder as an option . Thanks for really good idea !!!
Silver soldering (plumber's solder) or silver brazing? Soft soldering would be fine but the high temp of brazing would draw the hardness from the balls. And the plating on the balls may be resistant to solder.
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
"... 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!
As much as I'm here for the machining, I was waiting for the 'silly' mug merch shot. Where's the mug merch shot? I want my chuckle!! :-D
It’ll be back! I try to mix up the ads a little. 😁
@@Blondihacks yeah, its not the same without the "smug" shots..
Good job. With stainless you should use anti seize on threads as it is prone to galling and bolts can lock solid when tightened.
The biggest problem sith galling comes from when both parts are made from the same alloy. The problem can be reduced or eliminated by using another grade of SS, or carbon steel, brass, etc for the bolt. Lube or ant-seize is still recommended.
Thank you Quinn you are and awesome instructor!
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.
A completely different approach compared to This Old Tony but just as pleasant to watch.
You might want to look into purchasing a shell mill for surfacing. They are fantastic and give you a wonderful surface finish. Also they are not very expensive for sizes up to about 2 inches. A 2 inch one will run around $50, which includes inserts.
Sounds like someone missed my whole video about shell mills. 😁
@@Blondihacks Sorry, I just found out about your channel about 2 weeks ago. I haven't had chance to watch all your videos yet.
Quinn is getting in her practice for the "4 jaw chuck challenge."
very nice vice stop good job i always learn somthing from you. keep up the great videos. thanks.
I didn’t think the three threads were going to work. You pulled it off!
You know you’re gonna have to solder those balls on.
I have to get a Scotch brite wheel.
I enjoyed the video.
According to what i have been told by an aircraft engineer, three threads will give enough holding power to break the bolt before the thread strips.
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 are good! Excellent reaching.
Nice little project, Quinn 👍😊👍.
Thanks for the great tips on working with stainless! I appreciate your D-bit grinder video also!
Blondi if you use some oil of wintergreen when drilling stainless it will save your bits.
Great work and teaching skills!
I can't believe you got to that piece of wood before your cat did.
It wasn’t easy
I’m not waiting 25 minutes to comment... well done! Love it! 🤣
Thanks for sharing that. I am going to make one myself.
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.
AvE sent me. She be one badass metal maker. And Blondihacks is skilled too. 🛠⚒️🧰💪
Machinist toothpaste? Define?!. Oh mighty Quinn!,jpk
I'm not sure if you're talking about machining stainless or the morning bathroom rotation.
Cobalt drills work excellent in stainless.
303 is free machining 304 ,316, 321 etc non hardening . What happens when you dwell with your drill, is you friction weld your hss drill with the stainless that is why it becomes hard . Some kind of alloy.
Quinn, I just stumbled on your RUclips 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!
Just so you know I spit out my beer at 4:58..........that was funny. You rock!!!!
You should try brazing on the balls that's pretty much the standard way in industry of attaching balls like that.
