Detents are important. My company lost an airplane when the pilot accidentally moved the throttle control to IDLE, missing the detent. When he noticed the error, he didn't have enough altitude to get the single engine back up to speed, and had to punch out (eject). The airplane landed with gear up in a field, and was too damaged to be returned to flight. Pilot was safe, and the depth of the detent was changed. Expensive lesson, that. (mid 1960s).
Thanks for sharing the history of the little scrap that went back to work.
Such a grand machine Keith, looking forward to seeing it in action.
Cheers
I love that you used the old pin to produce the new one. Good job Keith!
Nice to see you bringing this machine back to working condition Keith.
This is going to be a heck of an addition to the shop once it's completely restored. The large work-envelope really allows for a multitude of opportunities 👊
Kinda neat that you were able to use an original part from the machine to make the new one! One of the things I learned early on in my career is to always work out of the scrap bin if possible, instead of starting with a fresh piece of stock! I did a little "side project" on my lunch hours at work many years ago. The rule was anything in the scrap bin was fair game. So I got some lengths of steel pipe and some flat pieces and MADE an engine stand! Only cost was the casters and a can of spray paint! 😁
Using an original part means the new and old pins were likely made of the same steel, which means the wear should be similar.
Another one of my rules is always use the shortest piece of scrap on hand that will yield the needed part.
No such thing as a scrap bin, it is the stock with unfound use receptacle!
@@Ambidexter143 ....Yep, he said that.
"Boring Mill Restoration" Really? I found it very interesting LOL
🤣🤣
🤭
I think it “turned out” nicely! 😂
These are your "back gear/spindle neutral" levers. One is different in that it has a lockout feature keeping you from binding up the spindle. IE when one is engaged you cant engage the other.
You have done a great job on the old machine. Hope you enjoy it as much as I did.
Nice job ! The rule on springs - diameter of wire, center hole and length. That determines the strength of the spring. Lighter wire is weaker spring. Boss wire and Boss spring.
You make the best videos of the lathe in action. Thanks!
Keith, you should consider adding basic spring manufacturing to your shop. When I started working at a Naval Air Rework Facility in '82, they were still overhauling R-1820 radial engines for the S-2 (and maybe the C-2 too, before it was reengined with turboprops). The Spring Shop was extremely small and basically consisted of one greybeard (which I am now) and one long workbench maybe 15-feet (~4.6-m) long with an attached back to hang tools, jigs, small fixtures, and materials from. I think he even had a small heat treat/tempering oven on the bench, similar to what you have now. He was next to the Lathe Shop and I assume that he used one of their Monarch 10EEs whenever needed for springs his "hand-cranked" fixtures weren't suited to make. You already have all of the "hard-to-get/expensive" equipment to make helical-type springs and other types too. You'd only need to build or procure the few jigs, fixtures, tools, and spring materials and then you'd rarely ever need to order & wait for a spring that may or may not be what you need or really want.
Morning Keith!
Good morning, Keith. Love the videos.
Thanks for the video,my son always asks me why I keep all my shorts and drops,cause you never know.🤗😎🤗😎
In 100 years I would never had a worn part that could be used as stock for a part for the same machine.; Just never wold work for me. You must live right, Mr Lucky😋
Yea, scrap bin! Tested metal! Thanks for your time and sharing. 👍😎✌️
GREAT JOB, GREAT VIDEO, PET THE CATS AND DOGS, SEE YOU ALL NEXT TIME...
Nothing like "Old Iron" fixed up and running!
That's exactly what you needed to mill that piston block casting you asked Adam to try his shaper on.
So straight forward to fix, when someone shows you how.
I totally forgot to celebrate the machinist yesterday!
Slow and steady wins the race.
Good work - as always! 👍👍👍
Greetings from Dresden! 😎
PS: When I first saw this machine, I immediately fell in love with it! It was love at first sight! 👍👍👍
Thanks for sharing!
Hiya Keith
Thanks Keith
You can make a fart a ball. I really like your videos. Greetings from the Czech republic.
that was nice
I'm so happy to see that you're taking you on the Lucas! I don't know what it is, that hbm is one of the most beautiful tools I've ever seen. That and a particular grissetti lathe from the late forties are some of the most beautiful machine tools I've ever laid eyes on. Please, please consider keeping it gray. The machines lines are too beautiful to distract the eye with a fancy paint job. Even if it were no added cost, I don't think this machine would look as good with filler and a perfect finish. It's beauty lies largely in the fit and finish in the context of what was capable at the time it was built. Beautiful machine. I'm very happy to see it with such a conscientious owner
I love this machine
Love your yeah fuk it attitude
Nice little fix with the original steel.
Nice work Keith!
Keith, another cool machine back in service.Thanks.
good video
Cool, the replacement is made using the original per-nuclear low-background steel. A future archaeologist will be fooled trying to date the repair. LOL (The springs will give themselves away). Can't wait to see some chips from this machine.
Keith you have a better knockout record than Mike Tyson!
Great video Keith, keep'um coming..
Keith another job well done!
Thank you for sharing. Enjoyed.👍👀
Thanks for sharing 👍
Good work!
Great videos! Where can I find the bandsaw rebuild for Dieresta?
Nice video Keith, one of those jobs that has been put off for a little bit, then turns out to be easier than original plan, and the re-purpose piece of stock falls into your hand, Karma!
Steel refined before 1945 is more valuable because it has no radioactive cobalt in it. You should keep the chips separate and sell it as pre-WWII steel.
Keith, another interesting project thanks for keeping the content coming. Please work on your microphone placement. The sound of it getting muffled every time you move is so distracting.
Hello Keith,
I the chain connected to the boring head part of a counter-balance weight mechanism?
TY
I see what you did there.
Hey Keith, when will you be getting back to the stoker engine ?
That is what this machine is being prepared to work on.
What ever happened to the stoker engine restoration....did I miss the finish of that project?
What part is it that sounds like it's running loose on the horizontal boring mill?
"I MAKE A NEW ONE". --MM
How did you determine what should be the spring specs needed to buy the missing spring pin?
i think its the od and id plus wire diameter and also pounds of force to compress
I think he needs this machine to align bore the crankcase main bearings of that steam engine coal feeder that he has on the back burner.
I hope so. I remember that job and was wondering what happen to it.
A couple of videos ago, he said the stoker engine repair was the job he is preparing for.
When do you and when do you not use cutting lube? Not a machinist just curious.
For light cuts on mild steel on parts like this you really don’t need lubricant. The camera view is also much clearer.
What ever happened to the stoker engine?
Nothing yet.
Assembling without oil a bit strange.
What happened to the steam stoker engine
Review the video of this machine from a couple of weeks ago and you will find out.
Cue the people who cry about a file being used on the lathe in 3-2-1….
I've never understood that particular prejudice. Should you also not use emery paper? Should Keith have made a form tool just to have a round tip on this part?
@@crichtonbruce4329 It’s people who “think” they know everything. Same people don’t realize there are even “long angle lathe files” made for the very purpose of using them on a lathe.
@@grntitan1 I had a couple of them. They worked very well indeed.
Great to see how to restore an old mechanical machine to usefulness once more rather than purchase a disposable Chinese machine.
First
@ PAUL COPELAND You never answered my question. Please get back to me.
What?
@@paulcopeland9035 Do you accept my apology?
@@MrNeverseeme ....Fill me in. I don't have your question.
