Oshkosh rear axle tube Part 1

[@johnnym1320]

we have a guy that will come to the shop and cut off the damaged spindle with a gas quick cut and he has new stub shafts ready and welds them on while its still on the truck, costs $1000 depending how far he has to drive, he is an old retired Dutch guy and his work is top notch like yours Keith

[@mnash6]

Thanks so much for posting these and your other videos. They provide a real education to those viewing. I love watching you Gettin er done.

[@nder12345]

i love your videos i am 16 and have a basement shop I a starting my apprenticeship on feb 6th thanks for the videos they are great. taught me abit also thanks!!

[@aryesegal1988]

Best job in the world, currently studying for a degree in M.E. Mr. Keith indeed knows his way around machine tools, I admire his workmanship! :)

[@PMPiper86]

Your videos have been, and will be very inspiring to me. As to the point of pursuing a Bridgeport knee mill and learning hands on. I've always been into machine work and your videos are by far, hands down; the best i have ever come a crossed. period. thank you

[@matttrotta57]

Thanks Keith It's uplifting I was hoping it was a song.

[@sknemo]

I'm an old mechanical engineer that worked with your type for many years. You are well versed in machine work, it would have been a pleasure working with you. I live in Oshkosh.

[@gangesexcavating]

Nice video, Keith. My dad loves your videos, and I do too. Thanks for showing how it's done and also thanks for keeping it real.

[@beautyaroundtheworld4658]

Love your videos, all your knowledge and experience, and you explain it so welll and you put great music on the video, love it all

[@tattoos1988]

Hi Keith I’m just starting out on the journey to become a machinist and I’m learning so much from your videos thank you for all the detail you include and techniques you show if I could co an inch of what you can I’ll be happy lol thanks again massive hello from London uk god bless

[@jayphilipwilliams]

Boy, that felt so good seeing that sleeve pop out!!!

[@billdlv]

Good run through on how to get the tube running true and concentric. It's easy to loose track of scale watching you work on your lathe. When you hooked up your chain fall I was wondering why then when you slid the tailstock out of the way I was like wow look at the wall thickness that's why. That's a heavy piece of pipe there!

[@monjury]

@KEF791 Very cool. It would be great to see more about that lathe in future videos. Thanks for putting so much into these videos, I really enjoy them.

[@KeithFenner]

That’s cool to hear someone is equipped to hand that service, just not in this neck of the woods ;{)---

[@vclubamp]

Logan, a four jaw chuck in good condition is the bomb dignity. Once you work with one a little, you will find you can quickly indicate parts as true as they are round.

[@KeithFenner]

Yes they would, to what extent I'm not sure, but more influenced by wall thickness and the texture of the mating surfaces, thanks for the comment.

[@pawayne63]

Keith with your knowledge you make everything you do seem EASY keep on doing

[@KeithFenner]

@monjury That is my hydrualic tracer attachment, there are a few of my videos with it being used, but have not covered it as the sole subject. Thanks for the comment :)

[@KeithFenner]

@huerdon Its a 17" Clausing Colchester, with a 29.5" Gap bed, 3.125" hole in the headstock and a hydrualic tracer attachment on the back side of the carriage. Like everything else I bought used, I have been through it thoroughly, to get it to run like it does... :)

[@KeithFenner]

Yes, for a better grip and easier dialing in!

[@gentharris]

I do this stuff for a living but realy like your presentation and sense of humor! I'm sure I will learn something if I keep watching LOL A person must have chips for brains to watch machine shop videos when they are off work from doing it full time LOL PS a trick I use to make concentric tubes out of crap DOM is to turn an about 10 degree included angle tapered dead center in place in the chuck to suit the tube ID the shallow taper will drive the part without slipping.

[@KeithFenner]

@SlowEarl1 The rough cuts were at 450 RPM's .100" depth at .010" feed rate, using dark sulfer base cutting oil, Thanks Earl :)

[@KeithFenner]

@citydriver The three jaw chuck is designed to hold round items running true, to the outside diameters of your material and I needed to hold the material true running, to the inside diameter. The four jaw only seems like work, because of the lack of experience, soon it will be, Wam Bam Thank You Mam! Don't seek short cuts, while learning, short cuts will find you, through experience...

[@jeffiscool1805]

That is one beautiful hydraulic press !

[@grzegorz16100]

Wow! In bloody UK I can't find anybody to do jobs like this. "Engineers" here like to say that thinks like this are impossible...

[@davidbackman4442]

"Impossible" today is often used as an abbreviation for "I don't think you can pay me enough to make me want to do that job for you". Or its near relative "I've got easier jobs lined up that will pay as well - or better. Why should I trouble myself with this?"

[@squito94]

I have no idea what your doing but it looks interesting.

[@KeithFenner]

I think I was surface feed at around .008 to .010 per rev. and a cnmp insert, around 400 RPM's

[@seanhazelwood3311]

To all of those who keep saying "Use Coolant instead of oil". Oil is cheaper, nearly as effective, and makes much less of a mess. Plus, coolant requires installing a system on each machine...more money. Flood coolant also flows whatever material is being cut all over the machine, which is a bad thing with brass/bronze/cast materials because it gets into all of the close tolerance areas on the machines and causes excessive wear. Machining coolant also gives off toxic fumes just like cutting oil, there is no such thing as "non toxic". Our shop uses nothing but flood coolant. It's a huge mess, the water soluble oil (mix with water) is expensive, and the flow systems are always messing up (leaks, etc.). The only machines that flood coolant works well on are the CNC machines because they are enclosed and recycle 90% of the coolant. If I need to weld/braze/solder a part after tooling, I simply use lighter cuts and use no coolant/oil at all to avoid contamination. My boss is always on my case about using cutting oil every chance I get. He understands and agrees with me, but he has to answer to other people also so I don't "push the issue" too much. There, I saved Keith from having to say all of that.

[@BR99GT]

Much appreciated, will try the combination next time something in steel comes my way . I assume the insert has a nose radius of 0.8mm or larger (or the equivalent English number-pardon the metric, had some training on dual measurement systems but most of the work is metric out here. ) Thanks again.

[@tfp777]

Nice project, excellent repair, as new!! :-)

[@KeithFenner]

What kind of project you need help with?

[@KeithFenner]

@mackdawg100 Cut the tank in half at the seam, weld the top to the bottom, with insides away from each other, put sand in the top for a ( Butt bucket ), so everyones not throwing their butts right on the ground :)

[@KeithFenner]

@billdlv Ya, thats a 1" wall thickness...

[@bigred91181]

that piece that was left of the axle that you pressed out looks like a shell casing : )

[@BR99GT]

Hi Keith, With no intention to flatter I can say that you show us great craftsmanship and skill and for that I am grateful. I have a probably daft question for you, on the lathe what feed and cutting insert you use on this job? I am not a machinist but I do a lot of machining at work, mechanical designer in a R&D outfit , despite that I can get good results with aluminium and bronzes I can never achieve the surface roughness you do on steels. Thank you for your time. Regards from Edinburgh

[@KeithFenner]

Thanks for the comment. ;{)-----

[@KeithFenner]

Thanks for the comment ;{)-----

[@KeithFenner]

No its not! 17" swing, other spec's have been noted in comments several times. ;{)---

[@montwo1]

lol I live about a mile from where that was manufactured and my father probably worked on it depending on if it was made in house at oshkosh truck or rockwell (my dad worked at rockwell).

[@KeithFenner]

I'm not sure on the tonnage of the Oshkosh. ;{)-----

[@BedsitBob]

Given how tight that tube was, I'm wondering if it was fitted using liquid nitrogen.

[@SlowEarl1]

How much of a cut are you taking at a pass and what kind of cutting oil do you use. Great videos keep up the great work.

[@donfoster1832]

When you are press fitting parts, all things being equal, do things like gray cast, stainless, or what not, have different gripping strength on the part being put in? Love your videos!

[@mackdawg100]

Hey Keith, what do you use that cut up blue propane tank for visible next to you at the start of the video? Always looking for a use for old tanks. Thanks

[@monjury]

What does the piece of tooling on the far side of the lathe's cross slide do? Power compound of some kind?

[@That_Teal_fummins]

I will say once you get onto using 4 jaws like 5 mins and it within .001 or.002 but from what i have heard the 3 jaws only get you wihting like .005 but i never used one

[@jakesako]

Oops just watched your press talk video , so forget my question, regards jake

[@CharlesGallo]

Why not between centers that way you know it would be running true instead of doing the endo?

[@diamaunt]

Keith, what's the significance of the chips off the lathe turning gold, then blue? you've pointed it out happening once or twice before, but didn't mention what it means. excellent videos, your customers are lucky folks.

[@tjs_welding_and_fabrication]

Nice Lathe. Is that a Logan. What size.

[@KeithFenner]

I believe back at the time of that video I used a couple loops from melody loops dot com. If I use some music from shared library's, that have been recently been offered to me, I will list the music in my intro. ;{)-----

[@KeithFenner]

I use a sulfer base cutting oil ;{)---

[@jakesako]

Hi Keith , what is the max tonnage of your press ?

[@UnitCrane514]

What brand of lathe is that? My guess is a Hendey?

[@futten3230]

im an amateur machinist but why not use a 3 claw chuck instead of the 4 that you have to work so much to adjust? dont you hae a 3 claw big enough??

[@matttrotta57]

What song is that you have playing around 9:45? I gotta have it!

[@stefanotorti4315]

what music did you use and can you mention it in the next video .

[@theessexhunter1305]

I watch a good few US machining videos and hardly any one uses coolant.... I think it must be for the affect on the video as it is much better for tool life and not heating up the work...Good TV but not good for the work.. You work is very good, just whack the suds pump on.......

[@chemech]

The Essex Hunter Did you spot all of the smoke around the part? Burning oil... Keith's using inserts in his tool holders, which are designed and made to cut faster and hotter - working on some alloys... He didn't say which alloy he was using in this part, but a leaded steel = free machining alloy also reduces the need for coolant in some work.

[@theessexhunter1305]

If it burns then it has become to hot...!! Keith is on top of his game, however he is just using a small brush and a few dabs of oil! As he is roughing out a large piece then I would guess he doesn't want the mess it would be a different case if it is a lump of 316 stainless Marine shaft... Suds coolant is designed to keep work at a stable temp and prolong tool life.. If work gets to hot it grows and can work harden...!! Thus my comment of turn on the suds pump!!

[@chemech]

I mis-stated things when I wrote "burns" - it mists off the surface - goes to a saturated vapor state which then coalesces as a mist... I've done some parts in 304 in a garage shop which didn't have any coolant system - about 9 or 10 years ago now... Lots of WD40 got evaporated - what a mess... Last year, I had to drill a bunch of holes in Unistrut which was rolled from 304L - that had already work hardened, and the lab I was working in did not have any coolant systems. For that situation, I found that using a garden sprayer and tap water gave the best results... Stainless is a different can of worms, and you want to be rather aggressive with it to keep you cutting edge always working on virgin material - work and heat will harden it in an eyeblink...

[@G3kRay]

the part you pressed out looks like a big spent bullet case

[@Shnick]

[@thekartracer29]

coolant man omg please use coolant it is so mutch better than oil

[@chemech]

collin ogilvie Coolant = about 5% vegetable oil in water - works great on newer machines, but you can set up the old school way using a free machining alloy, and carbide inserts, and turn relatively fast & hot, using a small amount of oil... There are different ways to do the job, and this is a good one...

[@thekartracer29]

well the smoke that come off is so unhealthy to breath in so thus coolant is much safter

[@KeithFenner]

Clausing Colchester ;{)-----

[@KeithFenner]

I believe that is new life & I got it at melody loops (dot) com ;{)---

[@gbowne1]

I always thought oshkosh trucks were cool.

[@tonyennis3008]

You seem pretty pissed off in this video.
