As the Shaft Turns

[@jaketank3217]

I came back to this Video because I will be welding a small shaft this next week. Thanks again Keith!

[@KeithFenner]

@tfp777 Lets change the abasive word stress to draw a simple contraction by heating. The shaft was running true to start, so the extra weld was just to offset the pull caused by varied bead laying. The saturation of control does have some depth and maintains its true running as the weld is shaped to size. Some final heat straightening almost always has to be done or at least checked before finishing the shaft work.

[@KeithFenner]

@Bonfield2002 No but you can apply hard facing rod the same way on needed projects and then grind to size, some large heavy equipment pins are done that way. At Northstar in Cailf. we used a submerged arc welding set up like a lathe bed with auto feed, creating cylindrical beads rather than linear...

[@KeithFenner]

@huerdon I used a Nitronic 50, alternate filler rod and the Shaft material is Aquamet 22. Thats all the detail I'll give out, on materials used in this proceedure. For those in this line of work, the info for this has been around,for years, I'm not going to do your home work, for you. My video was only intented to show the rebuilding of worn shafting areas, and the same process may be used on any weldable alloyed shaft, Thanks for the comment Jack! :)

[@KeithFenner]

When you are set up and doing a simulated vertical weld, slag is not trapped under the current weld pass, if left from the prior, pass, just as slag is not trapped between dimes on a single bead.

[@KeithFenner]

@G3SPARTO Personal preference, if alloys of filler metals are matched, wire feed process can be used.

[@ColchesterBridgeport]

Keith, looking forward to part 2. This is easily my favourite KZbin channel - excellent content, filming, editing and commentary. I am also glad to see you have a big old Colchester Mascot lathe!

[@TheKelstr]

This is one great video Keith, I too use stick for adding fill metal rather than Mig, I have always wanted to do "Submerged Arc" under the shield of the special "sand" but I never have , My friend worked for Lincoln Welding and he use to do it there in the plant all day , it really made some cool looking welds

[@gtsdesigns]

@3:38 for some strange reason, I couldnt stop laughing... I enjoy watching all of your vids, going back through some of the older ones Ive missed... Im always learning something through them...

[@operator41001]

You,your machining and Joe walsh for background music really go well together, keep the videos coming

[@astriknon]

I love how the radio in your shop always plays the same music as my shop at work haha.

[@Stubytube]

wooohh, good place to live, apart from having a workshop videos completisimo and I have noticed that you are a very good turner inter alia congratulations. one big hello from Argentina and rising good videos

[@KeithFenner]

In the manual mode of welding I prefer to lay the beads to gain depth and control the heat better in the lineal fashion! In the yards, we did have a submerged arc machine that we made, to do build ups in the rotary direction, used mostly for short hard faced pins of heavy equipment. ;{)---

[@FRUNTCASTER]

@KEF791 - - - I know all about that! It's hard for me to work with my dad. . . Lots of head bumping, yelling, and sometimes throwing stuff. Hahaha I still love the old codger, and treasure our time together, good and bad, and I'm eternally grateful for everything he's taught me. Good for your kids Keith! I hope they do well in culinary as well, it's a fine profession!

[@KeithFenner]

Thanks for the comments and best to you and your family! ;{)-----

[@KeithFenner]

I'm sorry; I was referring to the rod used for the repair. in the past I had stated that the slag I use to help hold the bead for the next past and it is hard to remove single beads of slag as it is so it's a win, win. Also the way I lay the beads is like welding in a continuous vertical weld position. ;{)-----

[@Futurple]

3:40 ha, did you see the picture on the wall the shaft fits through. That had me rolling. My philosophy, do the good job, do it right, don't cut needles corners, but have a good time while you do your work... Good job Mr. Fenner...

[@KeithFenner]

I do a lot of marine shafting and they are long sometimes. I straighten all shafting before running it in the machines that way your only holding it and not fighting any run out, while your trying to make true cuts. ;{)---

[@patrickfmooney]

The production quality of your videos continues to improve. :thumbup:

[@KeithFenner]

Makes me think of the miller 130 wire feeder I had, and still get to use when over the owners shop from time to time. It is perfect for the newbie, and material up to 1/4". There is a lot of new welders out on the market now and I would most likely go with a Miller or Lincoln, or at minimum compare the purchase to them for the quality. ;{)-----

[@KeithFenner]

@Katov2 Thats a dark sulfer base cutting oil :)

[@KeithFenner]

It is one of the recommended rods for the weld fusion overlay procedure listed in the material manufactures (ARMCO) book in regards to the Nitronic 50 compatible rods selections. ;{)-----

[@screwpull1]

I love watching your videos. Im learning all the time! Is there a third video? Im interested in seeing you pour and bore the white metal bearing.

[@KeithFenner]

Not for the marine environment, it is of a stainless steel material high torsion yield, But let’s say you were doing a machinery shaft, as long as it’s not leaded, like 12L14 or some of the higher alloys of steel that become brittle, you can build up an machine, a lot of worn out diameters, on most shafting used in the industry for drives and pivots. ;{)---

[@KeithFenner]

Yes, the slag left on for one saves time,in removal and after I got use to it, I also found it to aid in the suport of laying the next bead. ;{)---

[@ammagato]

Bravo!!!

[@BruceBoschek]

Well, I'm impressed with the speed with which you dialed that in between the chuck and the weld. I bet you've done that before LOL.

[@KeithFenner]

More to space out the interpass temp's and keep the heat uniform from one side to the other, makes a big difference on keeping it running true. ;{)----

[@futten3230]

fantastic work

[@SteveRobReviews]

Fantastic !! Have to ask if you used hardfaceing rods ?

[@tfp777]

@KEF791 I like your terminology, thanks for info.

[@KeithFenner]

You can always send a photo to my Email address found on my blog site. Anyhow, your size shaft may be cheaper to just replace with new stock. I rarely perform this procedure on any shafting below 1 1/2" diameter, sort of the expense line of judgement. ;{)-----

[@2009deerejohn]

You must be masochistic, lol. I took machine trades in HS and I had the hardest time with the 4 jaw chuck, but I've noticed you use that a lot, also I will steal that little trick of using weld to contract and straighten a piece, I like that

[@capncharlie7894]

that is some good work. wow. does the shaft bend when you cut the weld off?

[@KeithFenner]

Part two answers that, as we progress with the job. ;{)-----

[@capncharlie7894]

Yes indeed I saw that a while back. Awesome stuff.

[@KeithFenner]

In the yards we did a lot of flame spraying of ceramic coatings, on patrol boat shafting. ;{)-----

[@blakehensley7646]

I always wondered how you turned those long shafts when the wall was right there

[@chicagolathe-shopmaster-sh1680]

Did you normalize the shaft before turning? When you cut away that weld bead you lose your draw.

[@KeithFenner]

@FRUNTCASTER They both couldn't get their hearts into it! I know first hand its a bitch working for your old man, holding back, the blow it out yours and bumbing heads, from time to time, unreasonable exspectations...LOL... a real hard ass :) Once over that time period you get all the joys / bonds... They both are doing what they want in culinary and I support their dreams, what time is dinner :D

[@billdlv]

Keith cool video. I was wondering where the overhang went on your lathe. Now I know!

[@AstraWerke]

Wow, what a shaft! Do you often have such long pieces in your shop? And how do you center it to have it run true? I mean it won't be easy to make such a mass of metal move with that small plastic hammer or?

[@1995jug]

Keith i liked your hole in the wall, got a good lafe out of that, great looking job as always. thanks

[@bx2200]

What a great welding job! What kind of rods are you using?

[@MrStandup2p]

Thx Boss- like I said you're the "big boys"

[@lpfreak1708]

What song is playing at 13:50? I know I've heard it. I just cant place it.

[@63256325N]

Great video! By the sound of it your positioner needs a lube job....lol

[@KeithFenner]

1/8" rod compatible with Nitronic 50...

[@andywander]

Are you answering the question about the weld slag, or the one about the specific rod to use?

[@tfp777]

Straightening by adding weld and then machining it away seems counter to the function of adding stress with the weld. Does the effect go deeper than the amount of weld you remove? Just curious about what goes on, thanks. :-) I like it when the slag comes off effortlessly. Stuffing box abuse is right and very very common.

[@andywander]

Do you need to match the welding rod to the specific stainless alloy used in the particular shaft?

[@MrWFCJR]

If a guy was going to buy his first welder for light repairs, perhaps metal art. Hobby and handyman in mind. What would you recommend as a purchase?

[@tm868686]

so you take all the slag of after you finished the whelding all around the shaft? is it burning away when you doing pass after pass? i am just concerned that its not good to have the slag from the first weld under the second one and so on. but that doesnt seem to be a problem, or is it?

[@stevencarlino772]

How did you the shaft from warping due to the welding?

[@Stubytube]

question, you live where the movie trancurre shark?

[@KeithFenner]

Marine shafting is a high Nickel & molybdenum, super stainless steel. ;{)-----

[@rotlerin]

Hi Keith. Years ago as a centre lathe turner, I used to do a lot of spray metalling with kit from a company called Eutectic (I think). Had a lot of success with it. Have you ever tried it?

[@sass1ap]

why don't you move the tailstock to insert long rods or shafts into the lathe? is that too much work?

[@KeithFenner]

It most of the time is more work and some of the shafting is longer than the distance off the end of the lathe to the wall than out the back and behind the lathe, but some real big diameters and shorter length, i will move the tail stock. ;{)-----

[@sass1ap]

Ahhh I see :)

[@KeithFenner]

Jaws was filmed about 22 miles south of my house off the shores of Nantucket. ;{)-----

[@02stanggt]

The pair of lips cracked me up.

[@GnosisMan50]

forgive my ignorance but could you get the same results if you welded around the shaft instead of across it?

[@MrStandup2p]

I'm not questioning but looking to learn- why go back to the beginning, rather than coming up and back in the opposite direction?

[@andywander]

So you are able to weld over the slag for the next pass?

[@EddieTheGrouch]

Could I pick your brain a moment? I am dealing with a much smaller shaft (I am not worthy) and I don't know if it's too small to take the heat of welding up the area. I thought of Belzona metal epoxy but the worn area is a race for a needle bearing. The axle is maybe 5/8 or 3/4. I forgot to measure it. YT won't let me paste a picture link to show what I have :(

[@Katov2]

Keath whats the stuff you put on with the brush?

[@FRUNTCASTER]

That lip thing is hilarious!! Quick question (hoping I don't stir up a hornets nest), but how come your kids aren't in there learning the trade? Are they not interested in fab or machining?

[@KeithFenner]

Yes you do! ;{)-----

[@vclubamp]

Armco! My father in law invented nitronic 60 there!

[@TheBodvarg]

not high cromium alloy ?

[@TheBodvarg]

what electrode is that ?

[@TheBodvarg]

wouldn hilco hardmelt 600 be just as compliable i

[@KozmykJ]

More Joe Walsh ;^)

[@sc0tte1-416]

lmao Nice little glory hole you have there in the wall, quite the humor you have there. Nice video, I love watching metal being worked. A pretty precise trade with unforgiving tolerances. How much HP or Torque can that shaft handle, looks like it's from a pretty big boat, no? I don't know much about boats though so just wondering lol

[@KeithFenner]

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

[@screwpull1]

Ignore my last post. Just found the last video. Im watching on my phone and its a bit cranky!

[@MrStandup2p]

I,would have figured on something like utilizing the heat and consequently zig zagged... Which I'm sure isn't how the big boys do it

[@KeithFenner]

Nitronic 50 material ;{)-----

[@guubagaaba8391]

sounds like somebody needs a little oil. ha ha ha !!!

[@AYUSHJOD678]

🚗

[@DieselCrawler86]

I was on the edge wondering if you where a dirty minded old man or not. But once I seen the lips the choice was clear LOL. You know since every time you say "shaft" you kinda giggle.

[@GnosisMan50]

yeah, those lips reminded me of my ex girlfriend.. she was a great kisser! lol..
