Hell of a video for miniature precision and sequence of operations. It looks like a fun challenge and the raw materials won't break the bank. Another great video Joe, thanks and cheers!
loved the part where you esablished stick out using that drill rod joe .im baffled for now about how you knew the exact position of the front or rear cutting edges of all of those radiusing tools relative to each other . maybe that was what you meant when talking at the end about co ordinating tools?
Another great video here. Im literally "eating" these videos and shop gems so i can handle tiny items that i have to do in future, due to hobby that im practicing, model railways. Thanks for all these great videos.
Outstanding as usual Joe. I wish you instructed me instead the lathe dept head who made me nervous to touch a tool to the stock. I bought an old South bend heavy 10 and learned more in a week than the clown had taught me in 6 months.
I always love watching these videos for the hints I get which will help me out with my own shop work. Thanks for making these Joe. One thing... I'm thinking that a screw jack could have been helpful for drilling the small ball. Something with a sacrificial top cap of aluminium. And perhaps something suitably "model like". Something like a special 1/4-28 or M6x1 screw post? Something like that would help with small parts like this and perhaps on other bigger items that need support in a small flat feature where the big pads of a "normal" size screw jack might not fit? ... Oh good... ANOTHER shop tool project on my own list..... You're a BIG help ! ! ! ! 😁
Love the approach Joe - quite awkward with the radius tool work. In fact, yet again - making such tiny parts is impressive in the extreme - nice job :).
17:40 - "The print calls for two but I can only find out where to put one of them.". If indeed you only require one of them then I have an idea where you can put the other. Of course, it would mean you'd have to find the person that designed such a tiny intricate part in the first place 🤣 Amazing precision and excellent description of every step though, you make this stuff seem so easy 👍
Commenting early this is going to be great. Sweet work today my friend. I was thinking these handles would look great in brass. Brass and steel look so nice together eh.
@@joepie221 Thank you Joe!! Just what I needed to help me understand that process. You've really helped me grow over the past several years. I've got this saved to try out soon.
Any deviation in the part diameters vs the bushing diameters could lead to some chatter. One technique I've used is to put a small o'ring groove in the OD of the bushing before splitting it. Use a rubber oring small enough to stay below the outer surface of the bushing and it will hold the 2 halves together and still allow for installation of the part.
2:07 why undercut first? Why not back side of that ball (if you make your tool to be almost to the point on the left side). In that case, as I can see it.. you will have all of support of remain material up to the end of the cut. Yes it will be the same in that small portion, but you will not have extension of small diameter. After that you do undercut (which if we follow the real thing should be cone, not a cylinder, at least I always seen it done this way)
Establishing the undercut first really helped to dictate the grind and correct positioning of the tool. Without the undercut, you'd have to have a very accurate representation of the tool geometry to plunge it correctly the first time. As for the conical straight sections, I agree, but the print called for cylindrical. I did choose to make the backside region slightly larger than the front to give the illusion of a cone.
@@joepie221 that make sense I did small 3ball handle (not this smal, something about 1" total lenght), but doing it on chinese small lathe, that simply can't handle any significant surface contact, i did it in 'steps then file' technique. So.. I always look for as much support on the chuck side as I can get, and tht transition wil any way be finished with file

Joes Masterclass on small parts machining.
1000 thanks for posting this series. I always get something valuable.
Hell of a video for miniature precision and sequence of operations. It looks like a fun challenge and the raw materials won't break the bank. Another great video Joe, thanks and cheers!
Absolutely amazing Joe! I wish you would make a video specifically about grinding form tools.
I would love it if you would show us your process for grinding these "one off" cutting tools. Love your content and keep it coming!
you really like doing small stuff joe.
cheers
ben
Wow that is small! With a lot of features on it. Nice work as usual. ❤
Another MASTER CLASS from Joe on intricate machining and workholding- Thanks Joe!
You are very welcome
Joe, you never cease to amaze.
Fantastic job meticulous work thank you for sharing
Great sequential process on what could otherwise be a wayward piece. Cheers Joe. Keep well.
Thanks 👍

My pleasure.
as usual ..unbelievable
These kits are not for the faint of heart. Thankfully you show the best way to accomplish machining the different parts.
Thanks. I agree. these kits are serious.
Outstanding as usual Joe. I wish you instructed me instead the lathe dept head who made me nervous to touch a tool to the stock.

Nice procedure on the locating of the reference plane using a ground drill blank! Learned again here! Thank you Joe! Best! Job
Glad it was helpful! Its a good way to establish a starting plane for sure.
Joe - Excellent Video - Jim
Impressive as alway. Keep up the good work!
Thank you very much!
enjoyed….awesome
Brilliant Joe. I use 3D CAD to plan out work in the same way. A very useful tool to help visualize a process. 👍👍
These are crazy intricate tiny parts!
As always another great display of your skils & those shop gems are just awrsome.
Thanks. I'm happy you got something to take away.
thank you to the master to show how it can be done
One way to be sure.

Beautiful work.Joe.Can´t get any smaller.Thank you.
Big thanks
A master class Thanks Mr Pie.
WOW... amazing details on such a small part on such a large machinery :)
Now I wish I just had better vision. :)
👍🏻 thanks for sharing
It looks so easy
One step at a time, and plan ahead.

Very impressive!!
very impressive - as usual.
very good video Mr Joe Pie..thanks for your time

Thanks John.
Thanks for sharing
Wow ! Your the best ! 100% right on the number!
Great video , would be nice if you could show us how did you grind those radius tools
Commenting early this is going to be great. Sweet work today my friend. I was thinking these handles would look great in brass. Brass and steel look so nice together eh.
Thanks
mush appreciated.
Good practice for the ball handles on the Quorn......................................
Maybe someday.
Lovely job Joe. Good morning from bat shit bonkers Britain.
Good morning back at ya.
The small ball is about 6-7 fingerprint lines, that is tiny.
I love that when Joe says , " that would be a bad thing" he never has to say "ask me how I know" !
"for all you metric fans out there"
gee I wonder why we can't cope with "one 10th of a quarter or a zillionth of an inch"
it's just a number
@@rickjljr11 So's metric though 😉
Do you ever make tools from tool steel like O1 and then harden?
Please make a video explaining the technique for the broaching tool, making it, using it. Thanks.

Joe. How long did you spend polishing your penny 🪙🤩.👍🏴
👍😎👍
I was wondering just for the purpose of easier handling if you only 3/4 cut through on your bushing would it still hold well enough?
Any deviation in the part diameters vs the bushing diameters could lead to some chatter. One technique I've used is to put a small o'ring groove in the OD of the bushing before splitting it. Use a rubber oring small enough to stay below the outer surface of the bushing and it will hold the 2 halves together and still allow for installation of the part.
Very small indeed.
Huh. Very surprised you didn't make a nest or at least use a tiny machinist's jack when you were broaching that hole.
I did consider it Paul, but I knew the broach was newly sharpened.
⭐🙂👍
Как? Как ты это делаешь😮

I guess you spent the summer at the Hogwarts school of machining!
✋🏼🇦🇺👍🏼
You missed the opportunity to say “oh 62 and a half”
My mind has been suitably stimulated.
Now I will stay awake for days, thinking of how to make a spring loaded ball and indent to retain those handles.
