Keith, guy, I had to stop your video and comment. You are a man that's seen tough times and really appreciates some good machinery. That's why I watch you. I've walked a mile in your shoes. Not necessarily machine tooling but other operations where all I had to use equipment that was totally wore out and had to make do. I'm hoping to retire in a few years and use some of my recently acquired machine tools (a old 12" Sebastian lathe and a old SIMA Rossi mill). Keep on Keepin' on. You're a good man and you are an inspiration to do good work with what we have. Now to watch the rest of the video.
What a fantastic set up lesson! I used to help graduate students with shop projects and my hardest job was to get them to understand that set up and work holding was critical. The duck tape "safety" strap had me smiling. As always, thanks for letting us all watch!
....the more you talk about it.... the worse the old chuck gets.......incredible that you tolerated it that long.........Id be giddy too.... to have repeatable jaws again......great show.....your passion for your work and for teaching others is so strong..........we are fortunate to have your channel to enjoy
That part really looks like pneumatic operated high torque clutch. Looks like the ones I used to work with on Uraca high pressure water pumps, but the ones I have experience of is a couple of number smaller and only handle some 90 to 130ish horse power. The three studs held a lose metal disc between the friction discs, and the three holes held springs that helped disengage the clutch/friction package so the pump stop cranking. Sorry about not remembering the name of this clutch, but they were good stuff. Tfs!
Ah, Duck tape, the handyman's secret weapon. Every man has a roll hidden somewhere. Like the new chuck. I know whenever you used the old one you complained about it. Its good to have the right tools. Thanks for the vid.
You could use the t-slots to clamp bars outside the jacks to prevent them from moving outwards. This, and clamping on weights to compensate for off-center workpiece balance are two main uses for chuck t-slots. (I'm probably preaching to the choir here.) A few wraps of duct tape (Duck™ brand) looks like it should do the job, though. Speaking of wrapping the chuck, a friend has a brightly colored elastic bandage that he wraps around the outer face of his chuck anytime the jaws and/or workpiece protrude. It's not to keep the jaws from flying out (they wouldn't) but to keep him from putting his hand on the chuck as it slows down and getting hit by the jaws. A couple of wraps of duct tape would serve the same purpose, and there are brightly colored duct tapes as well.
One thing I've always wondered is how such delicate adjustments to run out can be expected to hold up under the pressures of turning it would seem to me just taking 10000 cut would throw the whole show off in a heartbeat
First time in the Kitty carrier.... My recommendation is a minimum of Auto darkening helmet, leather apron and full welders sleeves, on someone else while I'm supervising from another room. Cheers Eric
I remember 50 years ago sending the helper out to the truck to get a roll of duct tape. he just stood there. I told him to get going, he said "sure, and then I suppose you'll want chicken screws next."
Hi Keith WRT lengthining the T slots on the four jaw DON'T DO IT!! You'll weaken the chuck and regret it. You've lived without T slots on the lathe for 15 years I bet what you've got now will hardly be used in the next 15 years. Thanks for the videos Rod
Hello Keith, Hope your Cat tends to get used to the change. Superb technical video in sound and video views, than you. I found this to be an extremely interesting video with the piece being worked and other details mixed with the other plans of what you want to do with your 4 jaw, thanks, not least how it came into your possession!
If your jaw tightening tool is too long, maybe you can re machine the end of it so it fits better and shortens it at the same time. How do you feel about the length of the tee handles? They seem a little long to me. Great video, thanks for sharing.
On the cast iron, I think it was you that showed turning the lathe in reverse and putting the tool cutting from the bottom to get the chips to blow down on the rag instead of throw to the outside. I thought that was a very neat trick. How come not this time.
screw jack ............. great idea ............ I never thought of that, I just got different size hammers to get in the back side of the chucked item. Nice ... I learn more
keith would it have made sense to use the t slots and make up jack screws to bring the plate into alignment? those jacks would have made me pucker up.long live duck tape.
Wonderful setup work, as usual. I have to admit that it bothers me, though, that you say 'tension' when you mean 'compression'. It's the engineer in me, I guess.
How do you decide, in a situation like that, whether to attempt to build up the material with brazing or to simply face it and prepare an appropriate thrust-washer?
I by no means know what I am talking about when it comes to this work but wouldn't braze be a much softer material causing it to wear out quickly and you would be stuck with the same issue a couple years down the road? I guess you don't have too many options when it comes to cast though.
Question Keith, when having to build up a facing like that, how do you know how much to add without knowing what the face looked like originally? e.g. What if it had a ridge face above that surface and the owner doesn't know? Thanks, great videos and I sure learn a lot watching you.
don't worry Keith listening to you breathe actually makes the video very relaxing to watch haha. strange admission. the organics of your video should not be filtered.
Hello, you want to cut deeper slots for the tee nuts? You realize that this chuck is not solid, is there enough metal to allow you to do this without ruining the chuck? Good luck with that, it could be a thousand dollar error!! Think long and hard before you cut, there is a reason they never went any further!! Regards, Edgar
There's enough material, the slot won't be deeper from the face, it will be deeper / longer towards the center, the width and shape of the T-nut slot will be modified for good slide, but this chuck is designed with the material for T- nuts, not like a standard hollowed out, on back chuck. Cheers, ;{)-------
Hello Keith, no one has more respect for you than me. I just wanted you to be sure, that the chuck had enough metal to cut the tee slots a bit longer. Regards, Edgar
Not trying to be a grammar nazi nor making fun of dropped "r" in New England. Is "periphial" an engineering term or should that be peripheral... perhaps periphery? Trying to understand the full scope as well as the vernacular. And if that's just your word it's cool too. Just want to be sure I have a full understanding of the work.
Ductile iron is more "flexible" and less brittle than regular cast iron. The grain structure is more rounded.....unlike cast iron which is crystalline. Have you heard of nodular cast iron before ? That's another name for ductile iron....it has a grain structure of tiny nodules (round grains). Picture a clear plastic container full of BBs (ductile iron) or full of rock salt (cast iron).....hope that helps.
Jeff Silence the correct name is spheroidal cast iron ,which relate to the graphite structure. When I was at the iron works it was made by getting normal CI up to 1600 deg C in an induction furnace and pouring it on to magnesium in the ladle . They sampled each batch cut polished and etched then examined . Uses iron pipes ,nuts and bolts to use with the pipe , turns like steel curly swarf not grains , I installed a number of the furnaces up to 11 ton ,1.5 megawatts
Shane K Cast steel is truly weldable.....any form of cast iron, be it gray, white, ductile, or malleable iron is better off being brazed. All forms of cast iron have really high carbon content (2 to 4 %).....not good for welding typically.
What do you do to mix your audio? Does it have a background noise eliminator? can you use something like this? www.makeuseof.com/tag/remove-ambient-noise-audio-files-audacity/
The "easy way" to get a cat in a carrier is to set the carrier on it end so that the mouth is pointed up then lower the cat into it butt first. Works almost every time. :>)
Sorry , in German. I Would prefer, some Sentencesover the Problem and the Damages or, that, what is intended to do, some Words about the Way to do, and not this boring blabla abla what nobodys ist interesting. LOkk at yourself, how often you miss the Word s the dates and so on, its a sig´n, for its all said. Do you dont realice it???. so its booring, same to mee.. stop it. Lilith

Love the new chuck . Thumbs up Keith !
I cant complain about the sound quality in any of your videos i watch them on a 42 inch tv and the video and sound is awesome. great job btw
one4stevo I
The sound quality is awesome! Thank you for being one of the few how don't use a camcorder or cell phone and rely on the built in mic.
Oh man, I moved in October and was so busy I totally missed this series of videos. But I've found them now!
The serendipitous chuck.

Looks like the ones I used to work with on Uraca high pressure water pumps, but the ones I have experience of is a couple of number smaller and only handle some 90 to 130ish horse power.

Tfs!
T-nut slots are super handy. We mostly use them to put jacks in to true up sheave wheels before turning.
Great idea,I never thought of that.But I agree,once I've had them I dont know how I ever did certain things without them.
Keith, I hear that Tom has a plans for a 4 jaw chuck key! lol
Ah, Duck tape, the handyman's secret weapon. Every man has a roll hidden somewhere. Like the new chuck. I know whenever you used the old one you complained about it. Its good to have the right tools. Thanks for the vid.

A couple of wraps of duct tape would serve the same purpose, and there are brightly colored duct tapes as well.
Keith, you could use tee nuts with studs and connector nuts to do what your jacks are. You got the slots now plus you can lock them in.
The sound is great. Video too as usual.

Maybe you could make a bunch of threaded holes for toe clamps in the old 4-jaw chuck ?
persistence yes work with what you have and if you are good you will prevail
great stuff Keith!
real Duck Tape, made by Duck xD
Loved that part, keep up the good work :)

How do you decide, in a situation like that, whether to attempt to build up the material with brazing or to simply face it and prepare an appropriate thrust-washer?
Use screw jacks all the time!! Great tool!!

If the same thrust bearing that rides next to that surface blows out again the same results will occur. ;{)-----
Sweet labor rate sign in the back! lol!
Hi Keith, you mention grinding the outside of the chuck, would this be only cosmetic or would it serve some purpose
cosmetic, but also at a glance true would be my choice, if some movement was abnormal, you got a heads up. ;{)------
the old 4 jaw isn't a good doorstop, its a fantastic, cape hurricane certified door stop. :)
Question Keith, when having to build up a facing like that, how do you know how much to add without knowing what the face looked like originally? e.g. What if it had a ridge face above that surface and the owner doesn't know? Thanks, great videos and I sure learn a lot watching you.
could you use a thin magnetic strip glued to the back of the aluminum strips to hold them on?
It would most likely get crushed, thanks for the comment. ;{)------
Hi Keith, not a machines but intrigued that extra circular "fitting" at about 11 o'clock on the 4 Jaw? 5:00
A cutout for the original label I think is what you saw. ;{)-------
Heh heh, duck tape to hold the screw jacks in place, heh heh, I love it!
may be the runout or the bump on the outside of the chuck could be caused by the fall during the "Oriëntal Express" ...
don't worry Keith listening to you breathe actually makes the video very relaxing to watch haha. strange admission. the organics of your video should not be filtered.

Edgar, you're not going to tell Keith very much that he doesn't already know, that's why we watch him.
Hello Keith, no one has more respect for you than me. I just wanted you to be sure, that the chuck had enough metal to cut the tee slots a bit longer.
Regards, Edgar
No Worries! ;{)------
Am I to understand the old 4 jaw had dentures?
Not dentures, but it was in dire need of some orthodontics :-) The face of the jaws formed a bell-mouth.
That makes sense

What type of steel is used for the chuck wrench ?
Dennis L.
I don't know what was used for the one I got with the chuck, but I'll use 4140 or something like that. ;{)------
why can't you remove the screw jacks now that it is centered and trued?
location under pressure ;{)-----
Keith Fenner
I would not worry to much about background noise , Its a workshop not a sound studio, hell it all seems all OK to me.
Dam good all around videos
audio sounds good
I'm sorry if I sound like a troll, but why are you spending so much time for a surface that is not a final product?
no worries! ;{)-------
Seriously, why did you? Was it just the perfectionist in you?
Is ductile iron the same as cast iron?
Ductile iron is more "flexible" and less brittle than regular cast iron. The grain structure is more rounded.....unlike cast iron which is crystalline. Have you heard of nodular cast iron before ?

Stuart Hardy K.I.S.S. for the masses....layman's terms to get the point across.
Thanks Jeff, I thought since he said he couldn't weld it it was cast but he said ductile. How did Keith know what it was and that he couldn't weld?
Shane K Cast steel is truly weldable.....any form of cast iron, be it gray, white, ductile, or malleable iron is better off being brazed. All forms of cast iron have really high carbon content (2 to 4 %).....not good for welding typically.
Try Gasket-Tak spray to hold your shims. Made by permatex.
Why braze and not build up with weld?
This is a cast iron or ductile part. ;{)------
Stupid me. I heard you mention it after I made the comment. Thanks for clearing it up.
I hate taking the gap out... Never seems to line up just right afterwards..
