A Day In The Shop 4/13/2022

[@randallparker8477]

Seen this done hundreds of times... this has got to be the best I've ever seen. The legend of Fenner the 3D printing molten metal master continues!

[@ROTEsimplemachines]

I'm really impressed- consistent build up and keeping straight lines. Is it positioning of the Operator, or like a drawing artist, are there visual calibrations that assist the Master's hand?

There must be an T-800 exoskeleton below his skin. The fenninator strikes back!

[@Waiakalulu1]

What we're seeing is someone's skill developed over years of experience on tools that are setup in a shop that took a career of saving for. There's other folks doing this but few willing/able to share. It's amazing to think that all across the world there are people like this making "routine" repairs that keep our society intact. Another stunning virtuoso performance and a rare glimpse into a world that most take for granted.

[@Daniel_cheems]

It is a pleasure watching you practice your skills. I bet that repair is saving the customer a lot of money.

[@tattmanndann]

thanks for the day in the shop videos, it's kinda nice hangin out and looking over your shoulder.

Looks like you are back in the groove. Good job.

[@michaelrandle4128]

Thanks Keith, you make it look so damn easy, those of us who do, know it isn’t, regards from across the pond.

[@gordbaker896]

You have a very steady hand Keith. Hand gun practice? Have you ever just done a continuous spiral weld up the shaft? A special Ground connection would be required of course.

[@dennisleadbetter7721]

Hi Keith, You must have had a very tired arm after finishing welding all that. And I would agree the end result was very even for a manual process. I was also quite surprised at how straight the shaft had remained after all that heat input. Good video as always. Regards Dennis.

[@nothing2loud]

So glad you are back to making videos!

[@arthurirwin8235]

I could watch you turn a lathe on and off for fifteen minutes and I would enjoy watching every minute.

[@Hoaxer51]

The narration would be perfect and we’d walk away knowing more than we did at the start! Lol, I’m laughing but it’s true.

[@WilliamPayneNZ]

Keith hit on a really important thing in this video. Welding procedures! He is 100% correct and what he said is gold. As he said the weld repair is based on an accepted and documented welding procedure for that shafting in that application. When you are working to a welding procedure like Keith is you don’t play around with it you do it as per the procedure because if you don’t and there is a problem it can fall back on the person doing the repair because they didn’t follow procedure. It can be a big liability problem depending on what it is. It is why some jobs require so much paper work. It’s not to make peoples jobs harder but to make sure everyone is following the proven procedures so that a failure doesn’t happen further down the track.

For me I have found when running over severely interrupted cuts like that feeding that insert the other way helps to maintain my cutting edges longer. I noticed you twisted your tool post to accomplish a similar thing.

Very good result and very little, if any warpage. I'll be trying a longitudinal build up like that on my next one. ....Dave

[@radriand]

For pre heat I've used one of the Coleman camp stoves ( pump gasoline style ) underneath if it fits. It's so much cheaper than the O/A. Make sure to stow it safe prior to weld. Also I use a small out of spec linear rail and slider in the tool post as a forearm support . It also can hold the fire blanket and help keep the fireworks off your thighs .. save your pants.

[@WilliamPayneNZ]

Great video Keith. I sadly think a lot of channels have unintentionally done their viewers wrong by showing the spray welding process but not explaining the when’s and why of using one process over another. It leads to viewers who don’t know innocently asking questions because it was never explained to them properly.

[@henrikjorgensen1614]

[@johnkries8189]

Whew, That's a lot of work guy, but you did good.

[@Isadore123L]

I'm curious about the preheat done in your procedure. Welds on HY ferrous plates for the Navy spells out use of heat crayons to ensure adequate preheat and to avoid tempering back an HY100 or HY80. The preheat avoids cracks during process, but also avoids hydrogen embrittlement that can be hidden in the weld and cause cracks during service life long after a weld is done. 300-grade stainless steels have similar alloys to an HY ferrous though the amounts are all different. I've known toolmakers whose experience with repeated processing of the same metals taught them how to judge temperature by color the way Keith has done on this shaft. Have you encountered stainless grades where lower & upper heat control or the precision of crayons was needed?

[@ypaulbrown]

I find it intresting there are no slag inclusions from not removing slag on the next pass......Bravo.....that is one big slag peel for sure.....Cheers, Paul

[@ÁREAJ27]

Mais um trabalho cansativo meu amigo Keith, más com um acabamento fantástico!!! Grande abraço!!!

[@johnwright9622]

When Keith wraps the ground lead around the chuck to allow room for moving on to the next pass, does it induce a magnetic field into the chuck?

[@robertmyers461]

You do a good job on your videos I like watching what you do how are you not getting burnt Flux into your welds when you do all that welding without cleaning it up in-between passes I'm no machinist but I would think you don't want no deposits in your weld when you are gonna machine it I'm just curious about how that works

[@KeithFenner]

As long as you are holding a vertical weld pattern you can keep stacking beads without slag deposits or pockets.

[@TheAyrCaveShop]

@@KeithFenner Good info! Thanks Keith

[@1pokras]

A silly question from an amateur, why not spray weld? Thanks for the great videos!

[@weldmachine]

Spray Metal, could be used to build up a Shaft. But in this case the amount of material that seemed to be removed from the Shaft was a little excessive for a Spray Metal; process. We mostly used Spray Metal for small amounts of build up on the surface. Anything like what was shown in this video would usually be Welded with MIG. Hope this answers your question 😉

[@jim-me9wm]

Why not spray welding? I'm not a welder but see others use it

[@WilliamPayneNZ]

Different technique for different use case. Welding it like Keith has done makes it after machining as solid and sound as the shaft was originally. Spray welding puts a layer onto the metal surface which under certain circumstances and conditions can delaminate from the shaft. It all depends on what the repair is for and what procedure is being used.

[@arshadhussain5212]

Sir you are great teacher very nice sir from pakistan

[@jasoncohen6498]

What is the advantage of stick welding the shaft verus spray powder welding for the buildup?

[@scottthomas5999]

Excellent weld job. Vary uniform.👍🏻👍🏻 It would be interesting to know the cost of a new shaft, and the cost of the repair.

[@KeithFenner]

Just the replacement cost for that shafting material is over 10 k

[@Hoaxer51]

@@KeithFenner,Wow! I guess boatings not for weak of heart or weak of wallet!

[@thehaze1972]

A tip to avoid the nasty black soot when lighting the torch, I always crack the oxygen open just a tiny bit first and then the acetylene as usual, that little amount of oxygen makes the flame burn without sooting. Doesn't matter when you're outdoors but it sure is nice to avoid getting that fat soot on everything in the workshop. :-) Great video as usual! Big thumbs up!

[@Joel161803]

Could you automate this by attaching your mig torch to the cross slide and run in thread cutting mode ? Ref. Kurts at Cutting Edge Engineering AUS. Enjoy your videos very much, Thanks, Joel Shields

[@jwaflergmailcom]

I wondered the same thing. My only guess why not would be the heat distortion pattern. With His method the heat distortion is perpendicular to the shaft not parallel. With this being a rotating assembly Run out is critical. If spiral heat input is added this could cause radial distortion to the shaft. But yes I agree, automating this process would be a huge labor saver!

[@rustyshackleford498]

You could, And that would be typical for most weld build and turn projects. But as Keith explained, he is doing this job to a documented and approved weld procedure for this particular material/application.

[@dennisleadbetter7721]

The minimum spindle speed of the lathe would be far to fast. If you watch Kurtis when he does the bore welding, it's more like a revolution per minute. I would not expect Keith's Causing to be not lower than 25 or 30 rpm. The more relevant issue is he's doing the job to a specific welding procedure, which calls for stick welding (or more accurately shielded metal arc welding), weld beads parallel to the shaft axis and you would have noticed he continually moved 180° with each bead to limit heat distortion.

[@muhndkalil9234]

is this true that when welding on lathe its bad for lathe bearing ?

[@outsidescrewball]

Damn…what I would give to have a steady hand while welding….

Nice job, 2 things I noticed that were not done was; 1. Checking the preheat temp and 2. Lack of Rod Oven, otherwise very good job.

[@BKD70]

He explained in the video the method he was using to determine the correct temperature. Rod oven is not required because he is not using Low Hydrogen electrodes such as 7018. It is obvious he is not using 7018 or other LH electrodes because his restrikes are very easy, which is NOT a characteristic of 7018 and most Low Hydrogen electrodes. Probably using stainless steel electrodes since marine shafting is usually stainless.

[@WilliamPayneNZ]

That is marine shafting. That thing is a grade of stainless steel.
