That's precision plain and simple. Incredible job. Thank you.
Unloosening that screw to set belt tension must require a very small unloosener :)
As always, a work of art
The quill stop to top of part / move z axis for depth trick is actually brilliant, rather than relying on the typically less accurate readings from a quill. Thanks Joe!.
You Bet.
One of my students said, when you put the arm in the lathe fixture to better file away after the casting error, "Is he gonna pull the file back every time that little dogleg comes around?" That was about a second before you said, "Just don't turn the machine on!" (I paused the video before you said that.) I told him, "That's Joe Pie - he's just that good!" First year students are fun for their wide-eyed joy of discovery. It seems that you've kept a good bit of that and it's obviously not your first year. Way to go, sir! Thank you!
Many thanks for the vote of confidence and for sharing my material with your students. I'm flattered and grateful.
Always enjoy the shop gems Joe!
Thanks. I find them useful and gladly pass them along.
An endless supply or helpful tips. Thanks for the video keep on keeping on.
Thanks for the visit Harold. I hope you're doing well.
Great job!
I figured you were gonna go back to your reliable two-button-filing method to clean up that casting.
There was just to much movement in the part to get a satisfying finish.
Using brass also helps clean the file while working on aluminium.
My Master taught me to clean files with a piece of brass. It's so good! Always have some in my workbench.
Ever heard of this?
I have. I keep a 1/4" diameter piece of brass in my toolbox, sharpened like a flat tip screwdriver for just that purpose. It works perfectly.
@@joepie221 Nice!
Joe, is your wife building the line drive workshop model to house all the machines 👍🏴
You're so full of innovative practical solutions, I tip my hat to you. I appreciate your advise of not to start the machine when filing the rotating bracket. Wise advise.😂😂
The last time I used a lathe was about 55 years ago in high school. I have now purchased one and I am trying to learn/remember how to use it. I wish I could do 1/10 of the things that you know how to do. I'm thinking about going to the college and taking a course. Love what you do, please keep making these video's. Thank you
Happy to do it.
Fabulous. Lots of great tips - but the undersize gage pin tip is SO easy and such a great idea - I’ll be using that for sure.
@2:20 A gem indeed. A brilliant gem!!!
Looks very nice. The lathe finish job on that radius really worked well.
Really finicky assembly, but it comes together really nicely. Great workmanship as always!
Thank you very much! Its shaping up to be a great addition to the little shop.
Very good job Mr Joe Pie..thanks for your time
Any time
Great work,Joe.Thank you.
Joe, when I have to use a thin low friction shim I get an empty rectangular plastic 2litre milk bottle or 3l orange bottle and cut out the flat faces. Then drill the required hole and use small fixture in the lathe to get the OD to size.
Good idea. I'll have to check a few for thickness.
Thank you Joe another great video by a true master of his craft.
Many thanks.
This is turning into the best model build yet. That filing operation/setup reminded me of filing for a beaver tail grip safety on a 1911! Good stuff Joe!
Joe, seems like you've come down with a serious case of meticulitus!
Incurable if you're a Virgo.
Nice process Joe, I like how you think things thru before the chips fly.
Another great chapter in this series, & keep those shop gem coming they awesome.
As always, informative and interesting Joe... 🙂
Thank you for all the hard work in making these excellent videos.
My pleasure!
Nice work! Thanks for your time.
My pleasure!
Another great learning experience. Thanks.
Would you please do a "quickie" to show how you make those tiny washers?
-Kurt
I like that idea. Thanks. stay tuned.
Good work Mr P. all the joys of model engineering, My fat fingers sometimes dictate the project! and many tools are made to get at the tiny screws in tight corners.
Amazing work. Great tips. And you never disappoint!, Joe! Glad I hung in long enough for the obligatory unloosen...
I snuck it in at the very end. thanks for hanging around. :)
Love the lathe trick - say goodbye to pesky filing buttons!
Wow! The alignment accuracy you achieve is just incredible. I can only aspire to get that good with my model engineering machining. Thanks Joe!
Thanks. Its been a lifetime passion.
Hi Joe, You have always had good tid bits of tricks to clean up this or that and how not to paint yourself into a corner. We all sure appreciate those tidbits. Great to see that inclusion dissapear my friend.Things are looking great Joe. See you next post for sure.
Thanks 👍
@@joepie221 My pleasure Joe, My pleasure.
Thanks for sharing
👍 really appreciate the shop jems Joe!
Now I just have to have recall😁Thanks for sharing.
I always say the best engineer is the guy with the most catalogs and best memory. :)
Perfection!
Thanks John. Good luck with you new steam engine build.
Had an eccentric boss once, actually he was just plain crazy, but we called him eccentric 'cause we didn't want to get canned.
Nice one Joe always learning something from you also shop gems into my little black book Cheers mate
Cheers back at ya.
Great discussion/mentorship/build….please increase the volume of your 7 second intro music FFS!!! To maybe get the moaners in the comments to FO!!!
Great comment Chuck. Thanks for dropping by.
nice
Another outstanding installment Joe. I was wondering if you keep track of (log) the hours you have invested in these museum quality pieces.
I can assure you its much longer than the time represented on the video.
Good
If Joe is satisfied and like it. I am sure the workmanship is excellent.
Looks like it. Thanks Joe
Joe, you definitely get an Attaboy for this one and that should cancel that awsh## you had awhile back 😉! 😊 ! Would never have out guessed your set up on this one .
excellent, I like to see the details and appreciate the explanations.
very much appreciate this vids
Hi Boss, excellent stuff as always. Hope this is not out of line but I need inner bore gauges and the budget is a little tight (with inflation and all:)) and was wondering if you had an opinion on a name brand that is ok to start with? I see you have Shars in your list and made an assumption you would not have much bad to say. Is getting a set with the gauge a better option or getting the Telescoping Gage Set better as I do have a nice 1-2" Mitutoyo mic? The wife would love a new boot to stick up my $$$ since I just spent 11K on a new lathe so I better go a little cheap for now.
After spending 11k on a new lathe and still being able to type a comment, I suggest Mama gets a little bling before you break the bank. Then run off and buy stuff while she's smiling at her new toy. Just a thought.
What's the plan for belts? Gonna need them on the other machines.
I have a wide variety of black rubber bands headed my way that should be perfect for this application.
@@joepie221 Ok. They'll work and look Perfect. Maybe, at your convenience, post a link. I have a steam engine project coming up with a flyball governor. Need a flat belt for that. Thanks again
@@Gauge1LiveSteam Will do. Post a follow up comment as a new comment in a day or two. I'll link the product's in the video description If I'm happy with them.
and do the hokey pokey..
he joe, wat does "shop gem" mean in dutch (or english) ?
like your content very much.
cheers
ben
A valuable tip. A gemstone is valuable, so a shop gem is an idea or process in the shop that will make what you are doing easier, ie. it’s valuable to know.
@@mikeb1520 thanks !
Good explanation.
@@joepie221 thanks, I saw you mention that in an earlier video and use it frequently when boring small holes. It truly is a gem!
Hi Joe, I love the work you do and appreciate the rich knowledge you share, however, I find the intro music so annoying I have to skip it all together. Please change the into music. Don't get me wrong I think you are great and have followed you for almost ten years. Keep up the good work, from a fellow Diver and amateur machinist. I don't know if anyone feels the same, haven't read much of the comments in the past.
Hmm. Ten years, wow. I still have a few years to go till it kills me then.
I don't particularly like the music because it's sorta out of date, but I do think it adds to the "old-school-shop-gem-vibe" Joe is going for.
Besides, I don't know what music Joe is into, but I bet we would all totally appreciate some rock! 😋
HEY JOE! What do you think? Time for a new intro?
Keep it old school!
FFS
@@grntitan1 sorry FFS? Don’t know what it stands for
For F*#k Sake
Thumbs down for this one Joe! No Unloosen I jest... Great work and a few shop gems thrown it as well! Stay safe n well. TFS, GB :)
Ahhh. Got ya. It was at the very end. :)
@@joepie221 Yep caught it this time, Cheers Joe Dude👍 GB :)
That Back Boring trick. I've done similiar in the past. Both with a boring head and with a K&T Rotary Head Mill. One thing l found with small diameter parts held in 5C collets. If you use a Disk Type Collet Stop the collet not only holds the part radially but also puts a tension load on the part. This happens because as you tighten the collet it draws the part axially into the collet block, spindle or what ever the collet is geing used in. This tension really helps with rigidity. Also exreme useful holding lengths to shoulders if you have a variation in rough tirned parts. Every .001" difference in diameter is .003" in length in a 20° included angle.
Hardinge sells the Disk Type (1) collet stops but they are dead easy to make. 2" diameter bar stock. Counter bore the back side to clear the collet body. But, always a but, the spindle face, indexer face, or collet block face must be dead square to the centerline of the device holding the collet. And the faces on the disk must be parallel.
1) They are in their workhold catalog.
I love your OCD aesthetics!
2 for 1
Turning in a collet in a mill vice = Gem.
THANKS Joe.
Joe, you are always showing methods for indicating parts and namely odd parts. Do you ever use tooling balls? Would love to see you put them to use.
As requested. Enjoy. czcams.com/video/FnEl6Kj-F-E/video.html
@@joepie221Awesome, thanks!!
Joe, shouldn't there be wrench flats or somesuch on that eccentric part? How else would a miniature machinist be able to tighten it in position?
Right? or at least a cross hole.
✋🏼🇦🇺👍🏼
I'm surprised you don't have or haven't built a filing machine, I've seen a couple people build one from a kit.
My filing machine wouldn't use a small jewelers file. It totally defeats the purpose.
It's fantastic you don't need a mechine to do that but the mechine became a holding device . Not every thing needs to be mechined. Just need attention
Like I use to tell my apprentices, "this machine holds the part and the cutter spins, and this machine holds the cutter and the part spins" how you apply that knowledge is wide open. Just ask me before you do it. :)
