This is why I like watching these videos. You pick up little stuff that you'd rarely think of yourself if you haven't been doing this for 40 years. That little catch tool he comes up with at 11:00 is stupidly simple but slick. I've been sticking a ball point pen in there, risking tearing my arm off, all while trying to complete the parting cut, when all this time I could've just used a little piece of rod in the tail stock drill chuck like this. That kind of knowledge is pure gold.
The process of rolling cold rolled steel leaves compressive stresses in the outer layers of material. When you cut the slot, those stresses closed up the slot. Nice project. Thanks, John
Hi I'm not a machinist(electrical fitter/engineer) from Scotland ,only about 100miles from doublboost. I found a tap like the one frozen in the adaptor you showed and always wondered why, now I know , it was in some of the tooling from my granddads workshop, Enjoy your SNS every week
Anyone that can afford these tools and machines can buy a 3 dollar calculator and commit a couple of conversion factors to memory. It's not rocket science folks. 2.54 cm = 1 inch = 25.4 mm
@@WisdomVendor1 obv. Its not but a guy talking in Workshop English about imperial sices ...If you are not used to you dont have a feel for how much it is like non machinists usually dont have a feel for whats a 0.01mm I dont know how you like to watch Videos but i dont like to have to do conversations If u do u could watch movies in Mandarin and do a simple google translate Translation Well Imperial Sices are based on Metric Sices with a conversation faktor guess thats because imperial Guys like that so much
Adam points out that the shanks of taps are oddball sizes. While that's true for imperial taps, the majority of metric taps (especially HSS ground thread taps) have shanks from the same diameter series as the standard ISO thread diameters: 5, 6, 8, 10. 12, 16mm etc
Adam, I just found your channel. All I can say is OUTSTANDING !! Your skill combined with your knowledge and ability to logically explain the projects is exemplary in every way. Thanks
Hey, I know nothing about this kind of work but it's been great to watch a true craftsman produce such a precision item. Thanks for a great video with an excellent presentation.
Hi big chap, watched SS Part 1 tonight in Helsinki Airport and Part 2 in Amsterdam Airport before flying home to Scotland. Great work Adam, you set you standards very high. Thanks for sharing. Kindest regards. Joe.
Revisiting this old SNS, I take the liberty of saying:. This is your passion, your talent, your calling. You shine in all aspects. Make more videos, just like this one and 500k subscribers will be a reality soon.
I like it, thank you to you and your mentor. Better ideas. I built a bunch of tap drivers with set screws to hold the square but the screws forever come loose. This is a far simpler and better idea. Usually simplest is best.
Hey Buddy, I was feeling for you on that slitting saw when I saw the steam. Great little project for power driving those bigger taps. All the best, Tom
oxtoolco Tom, you know like me sometimes those saws can be a pita...😣 When they work right they do a good job. I finally prevailed off camera. Might have been the language.
You can't blame the slitting saw if the pre-stressed material closes on the tool, given the chance. Can't avoid that with the material, though, can you?
Steam is not the same as water vapour. Steam is a gas; water vapour is a liquid, *and* a gas, in equilibrium with each other. It's badly explained on many websites, but this is quite a good explanation: www.differencebetween.info/difference-between-gas-and-vapor
We made a set of similar adapters for various valve stems in our Navy valve rebuild shop for a drill motor driven globe valve lapping setup... talking about production, an aircraft carrier has a lot of valves to work during a shipyard maintenance availability. Fond memories, thanks for the share!
Thank you for your videos! I know absolutely nothing about machining but I’ve always found it fascinating! I’ve been thoroughly enjoying your videos and I’ve enjoyed learning from you!
I am enjoying your channel, very interesting always. The camera work is impeccable, always perfect lighting and focus along with the volume. Thank you for your time and effort in explaining clearly, what you are doing, for us novices. My Father was a machinist, back in the '30 ies, and I now can really appreciate what he did. P.S. Nice shop you have there.
You need an SPV tapping tool like what I have to tap on the K&T. Probably be handy on the Kearns as well. I love not having to worry about turning too hard and braking a tap. Those drivers sure look handy for when you don't have one!
Adam if you want to loosen that up a bit use your torch and give the side away from the slit a bit of heat it will pull it back and give you clearance. Great project.
31:21 "Like it was made for it!" made me laugh so hard. We had a machinist at one of the railroads that I worked at (a half a lifetime ago) that would exclaim, "Like it grew there!!!" Good times in that shop. Great times. Anyway, yet another excellent video, that I just caught up on, Adam. I need to go snag me one of those snazzy pocket tees of yours before it's too late. It's the least I can do to thank you for such great content and many smiles.
I a man older machinest and tool and die maker i am retired now and disabled and reopening my small shop 'I am using bench mark horizontal 1930's and the vertical is a 1940's i pulled out of dirt in a friends back yard The old lathe is a 1940's also i pulled out of the dirt i am rebuilding them now having to rest a lot now i have been watching your vidoes and they have really help me with my project Thanks for shearing your knowledge
Adam, thanks, you made my day with the description of the adjustable spanner as "all Sixteenths", love it, never heard that before, cheers from Scotland, Spud
This gives me some ideas for if you wanted to mount taps in a hand drill for field work. Sometimes you can't chuck stuff in a mill and tap wrenches aren't practical either. Putting your tap in a hand drill or on a socket to turn with an air ratchet is sometimes all you can make happen. Milling something with two flats in it like this might be the trick. Good video. Thanks Abom.
Hello Adam, Man that was one hellaceous feed! I would have brought a sleeping bag for next day's leftovers! Thanks again for some wonderful videos. Always one of the highlights of Saturday night for me. Take care. Doug
This is one of my favorite. just the thinking out side the box instead of trying to drill a square hole you just cut a grove with a hole the size if the square part of the tap. it is awesome.
I enjoy your videos and definitely hope you have an apprentice to pass your knowledge on too. Sadly, skilled Craftsmen/Tradesmen are a dying breed. I'm 51, work in a steel mill and can tell you, in just the past 20 years I've seen a horrible decline in tradesmen who take pride in their work or have the ingenuity to "make it work".
This is a very cool idea, and one that I shall certainly be using. Four years later you now have that tapping arm, but that's going to work in all situations. I always worry about power tapping, and wonder what would be a ball park tap size to be safely strong enough. Much as I hate abusing a chuck by holding a tap, that does at least give a sort of safety margin by slipping when the torque reaches a certain level. That is not going to happen with a collet driving a positive grip on the tap. I'm going to try using this method on 6mm and upwards, but I have a feeling I'll start out going just a tiny bit over on the tapping size. Say 5.1mm or 5.2mm for harder stock. BTW, I did two years at Ford UK's Apprentice Training school (starting in 1967), but I learned so much more from the older guy I shared a bench with, when I got to the big boy's work shops. Cool tricks and tips just like in this video, that helped in real world situations. You have to do the work to _really_ learn how to become good at it. Instructors who came straight from college just don't cut it.
Good comment, I know what you mean about taps slipping an observation I made about this design tho is although the adapter is mechanically driving on the flats of the tap the adapter itself is still round in the o.d. and driven in a round collet. This is in no way a criticism it’s an observation I assume the greater surface area and larger collet allow more torque to be transmitted 🤔 👍🏻
Hey Partner, I just picked myself up a Bridgeport and am looking forward to testing it out for trueness and travel. I was lucky in getting a very nice set of collets along with the deal. Who knows maybe I might show a couple little jobs I have to do right soon. I also enjoyed that tour you had in Witchita of all that collection of various machinery from days gone by. Some of which I grew up with. Thanks for your great video as usual. I don't possess your knowledge but can make what I need. You take care in these covid times. By for now.
Very cool and helpful video. I just picked up an old Logan lathe and started to play around with it a little. No real use for it....but you never know when ya need it!
That is a really nice collet holder you are milling with. Cast Iron strength ! Ok when sawing a tree down one uses hard plastic wedges to keep the slot (tree) from squeezing you down and trapping your $1K saw until another saw saves it !
This came at a very handy time for me. I acquired a nice Tapmatic head but it came with no collets, (it uses a quick change type). I'm pretty sure I can make a set that will work for me. Thanks!
I used to attend the Moultrie Swap Meet every November. Huge event! Took 20 hours to get there from PA but well worth it. I worked for Pypes Exhaust, an exhaust manufacturer. We had a huge black NASCAR style tractor trailer that we would set up. I don't remember the location because that airfield is huge !You can find Everything and anything there.
I make them to drive in but I let them collar have a bit of play so it will pill past the square drive then you don't have to worry about breaking the tap , it allows for use in a drill press with no reverse.. I had an old mentor too Alex the Scot man. He was a real old time machinist. Real super if he liked YA you were in . YUPP he liked me shared a lot of Kool tricks. Loved just hearing him talk.
Why the hell didnt I think of that ? Struggle with tap holding and driving many times on projects that need to be extremely accurate ... Great idea ..Thanks for help !
Okay Adam, here's your chuckle for the day. I'm in Thailand. That translates as 'outlet for cheap crap junk too crappy to justify the cost of shipping overseas'. I needed to tap one hole. ONE!!! So I toddle off to the local hardware store. A set of 6 metric taps for only seven dollars. Wishful thinking I was hoping the entire set might be able to tap one hole. Odds are, right? The hole to be tapped is spring steel. First tap untapped it's cutting edges, turning into an odd looking rod. Second tap is now shaped like a corkscrew. Obviously they are made of poor quality unhardened mild steel. The remaining 4 now reside in my collection of Pure Crap beside a set of drill bits I can bend with my fingers. The heck with tapping the hole. I pounded in an undersized screw coated with epoxy putty. Thanks to the epoxy it is water tight. Nothing beats a claw hammer for doing a little precision repair work, right? I'll save the rest of the taps and drill bits just in case I have to drill and tap some PVC pipe.
Ryan James That's just sad man. It's really upsetting to see people actually wasting there time and resources to profuse junk tools that don't work, And waste the consumers time and money for buying them and using them.
How about the method I used for finding a real mechanic here? I went to garage after garage inspecting. Claw hammer in the tool box and the floor is the workbench and I'd go on. It took me NINE YEARS to find a decent mechanic to work on my Jeep CJ3. Nine years to find a mechanic to fix a vehicle specifically made to be fixed by your average GI assigned to the motor pool. Your videos are great! Keep them coming!!
Adam, that is really neat and useful. I have the luxury of climb milling as my little CNC has ball screws and R8 spindle/quill. First job on my DIY EDM attachment will be making neat slots.
sticking the catch rod in the tailstock chuck is brilliant!! no idea how I never thought of that.... Always seemed to require 3 hands to do parting.... one feeding (or ready to disengage power feed if something goes wrong) one applying coolant (no flood on the lathe here) and one with the catch rod. I've usually just stopped with coolant almost all the way through and picked up the rod then. And I must say those indexable parting tools are great! I actually enjoy parting when using the seko or Sandvik with a fresh insert, even parting stainless
Abom79 it's a great idea. I can't believe I've never tried it. I've got piles of brass round from 3/32-2". I've got more parting to do today, I'll give it a shot!
I have been looking for a simple, changable tap driver for some time now. THANKS! I plan to try to make a home shop friendly version of a tapping head and this is the first piece. It looks like a 3/4" OD will work for #4 up to perhaps 3/4" taps or perhaps a bit smaller on the large end. I also hope to add a die holder with the same 3/4" OD shank so it can be used for external threads too. I ordered a couple of 1.5" bolts to provide the stock for the die holders. Thanks again!
power tapping scares the crap out of me so I try to avoid doing it,but there's so much really good information in this video it would be wise for anyone to watch.heard about this guy from a bunch of folk but my first time seeing him...gonna be paying attention now!
Wow. What timing. After watching one of Tom Lipton's videos where he talked about tap drivers (or at least problems driving big ones), I decided to make my own. Finished it two days ago, and I then killed all of the threads on my drawbar (coincidence, not due to overtightening to keep the driver from slipping.) Yours looks a lot simpler Mr. Booth, but I can't believe we both made a tap driver around the same time. A short video of mine should have just posted to my channel, it's an r8 design that uses bushings and allens to hold onto the square.
Hi love that tap holder i.ll be making some of them for my workshop i would love a machineshop like yours but i do ok iwatch your channel alot and learn a lot thanks adam PS sorry about your dog
A useful addition to the set of tap drivers would be a set of adapters with the same size outer diameter to hold the appropriate tap drill. It would be easy to grind flats on the drill shanks to grip in exactly the same way. That would make it easy to swap tools to do multiple operations at the same location. A set of adapters to hold a spotting drill (one for each outer adapter diameter) would complete the set.
