Kieth- It is a joy to see someone repair stuff the proper way. So many hacks out there that just don't care. Nice to see someone who reads the critical info from a book and actually follows it. You bet it costs extra money for good steel and pre-post heat. Better than having the weld crack. Some guys try and do the minimum and rationalize that it is not their fault when something goes wrong. Nice to see someone takes pride in doing the best possible work. Awesome.
Hey Keith; I just found your sight about 2 weeks now , I cannot believe the hrs i have watched your vids. THEY ARE GREAT. I just keep learning and rembering things i had forgotten years and years ago. Keep them coming. Regards Xmodriver
It's refreshing to see someone take such pride in their work and to actually do the research and perform the necessary steps to provide a quality product. Preheat, interpass, and post heat are terms that aren't mentioned in most job shops. You're a talented fella and you do an excellent job in your work and on your videos. Thanks for taking the time.
Thanks for the comment; it did take a lot of rods and a lot of constructive criticism, from those who cared. I believe a machinist can be a welder and a welder can become a machinist, given someone with drive and passion. Self teaching is hard to get a well rounded perspective, on the variety of procedures, just saying that in a shared learning the growth is much greater. ;{)---
As always, excellent work and detailed information. Watching you move that heavy part made me think that it's a good thing that hernia operations aren't as gruesome as they used to be.
2 days of watching Keith so far after coming home from the shop, just over 3 hours on this series alone and i feel like I'm on vacation !!! Subscribed :) "The welding is kind of permanent" made me LMFAO and fall out of my chair.
Even with the slight angle I gave the face to clean the old weld surface, it wasn't extreme enough to hinder the penetration. With the plate flat and the temperature of the pre heat and amperage, just right, you can see the drop or cutting action forward side of your puddle. It's not like if you worked in a V valley position, where it is easy to roll over slag. ;{)---
Too cold for garage work today, so I'm watching all the Beaver episodes... At 3.39 mins...."The welding is kind of permanent"....LOL! I don't know if that was intended, but I found that one comment a little amusing..:) Very nice video again!
I'm just watching for the wood pile shots and stove stoking, but your camera work and dialog is superb, so I am thoroughly mesmerized by the fabrication! Thanks, now I'm off to Home Depot!
keith I'm your fan, I'm almost buying a lathe and leaving my father had a heart attack when he sees it in his garage. here in Brazil these equipments are very expensive. a lathe costs around 10,000 if used. and a new car about 30,000 for you to compare. Hugs from your friend leo.
No problem Keith, always glad to add in information. I use the Matlweb information on all my work. Most of my work requires specific material data especially on temper/hardness and composition so that the right machining data & cutting conditions can be applied so that we get the right SFM's, RPM's, etc.
Keith nice work! One of the guys I used to work with, an old school designer, had that Jorgensen book, very useful. Doing that welding process I could tell you really planned that out you had everything ready and laid out and had a grinder ready, etc. When you needed to be quick you were, but not frantic. I guess working by yourself you have to be that way, no one around really to get you that chuck key ;)
This is a very good set of videos. Again I appreciate how much time u spend doing the videos, editing, and even reading and answering all the comments. I too would like to know where to get those two books and what they were.
Its time to make some sort of ratchet lock on that swing arm of the press table... Love your machine work Keith.. lost you at the welding..., i could not even tell what type of welding would be needed :) (i would probably tried the stick welder, without preheating :) )
WOW that tracer attachment is awesome!!! I have never had the opportunity to use one and didn't realize how versatile they can be. We have a Haas TL3 at my work that has intuitive programming that makes doing chamfers and radii a breeze but this is more interesting by far!! I'm trying to get thru all your vids LOL
I combine both inputs, but you can find all of the info for the pacific rod alloys in the Lincoln book, the EMJ book gives the pacific’s more for the marketed material specifications. ;{)---
It would be to hot and slow with TIG and It had been welded with MIG once already and failed! Stick is my preference because I feel that my control of penetration and uniformity within the weld is better than the other two processes on this type of project. ;{)---
IR pyrometers are quite accurate even on a polished or glossy surface. We tested high quality units compared to a contact pyrometer, but to each their own.
Ya your right, if even on the lowest separating ranges there is 5 % more in 4130, it was the added nickel mostly on 8620 that calls out for more attention. thanks for adding in your feed! ;{)---
The front section of the shop averages 50 to 60 deg's during the winter, with the heat blowing in though the door by my drill press, but was 78deg's after that job. I feel stick is the superior method; I do more cutting and machining on my own build ups to confirm that to myself. ;{)---
The two books are The Earle M. Jorgensen Co. Steel and Aluminum stock list and Reference book, and the Lincoln Electric- The Procedure Handbook of Arc Welding ;{)---
The basic of; Stress relief, is creating a temperature range and control at which an alloy relaxes all the pulls and contractions, caused by single or sets of stringer beads created during the welding process. ;{)---
That is a personal witness mark proving I didn't take any more, off the thickness, than was necessary to remove the run out! So many will keep cutting, till they have that perfect finish and remove strength. ;{)---
No, even though the first move, I set the pin on top, my regular pratice is as I did the second time, always keep a pin in some where. I have smashed a few things that were below and I wasn't paying attention! ;{)---
I get my blankets by trade! You can get them in Mc master and a lot of places on line. Here are a few things for search; Carbon blankets and Silica fabric flexible is good for 1800 deg. Some of the fiberglass blends out on the market are only good for around 1200 max deg. ;{)---
It was a time factor, the strees relief was an extra hour after the weld to heat and then sat while I made a trip to Vermont and was ready to continue when I returned, so no time was lost doing it. Around 3 K ;{)---
That weld positioner would also be awesome for die-threading and tapping on really tuff materials. You might need to beef up the frame and/or set it up on a worm gear for mondo torque.
Thanks, Keith! Those were very nice strong looking stick welds! You and Jody make producing good welds using any of the three processes look very easy, but I know it's harder than you make it look! Did it take you years of practice to master welding? Was it harder to learn than machining? Do you think it can be self-taught?
I contemplated that position, but knew I would have the better side of my beads making and control against the plate instead of the shaft which could be machined more than removing any more material away from the plate, if I had any under cutting. ;{)---
I got that new scale and had planned on weighing the part and the four jaw, but got to pushy on myself to get the job done and out for the customer. I guess about 200 pounds when finished. ;{)---
Yes they are and have pretty close to the same respect to their mentors as I had with mine at that age. With the same kind of getter done attitude! ;{)---
hello from Brazil ... congratulations on the videos are very interesting ... One question: your hydraulic press, was built by at yourself, how many tons it works? very good
Hi Keith! Professional work as usual! Absolutely fan from you, your work, your art of work. Can you tell me/us the titles of those two books you used? Greetings from Hungary!
If it was already 82 degrees in your shop when you started preheat and weld, it must have been well over 100 by the time you finished...that was a LOT of heat, good thing it's winter! Process question: you chose stick instead of MIG to ensure adequate penetration?
woo, i was a chef for 11 years.. i got into metal through knife making for kitchen minions. i wish them the best of luck. personally, i hope i never have to set foot in a professional kitchen again!
I was combining the information's I frequently use, Lincoln book, my 1980's Emerson's buyers guide and the rod manufactures specifications . Most procedures are made of a collection of information on all components in the blend. ;{)-----
There is a big problem with these IR temperature meters. If your surface is even slightly shiny you wont get accurate reading. Try sometimes with polished stainless cooking pot that has boiling water in it. You and up reading something that is not even close to the surface temperature. Sticks work no matter what kind of surface you have.
Keith, where can us faithful viewers get those blankets? I need several for an OxyFuel,Cast Iron welding job and the blankets I have from the welding supply,just melt!
After all that nice machining I would have used some anti splatter spray to keep it clean. You are a master. Would it have been overkill to put a woodruff key into the middle before welding it up?
TIG welding it all would just have been insane! :D :D But I think, I would have TIGed the root pass. Just to be 101 % sure, I don't get any slag down there. :)
Just finished part six. Seven isn't up yet. Will watch it as soon as it is. Keith, a question about this shaft design. Would you consider this a good design with that carrier plate welded onto the shaft? Is there some alternative that would be better for something this heavy that gets that much of a load turning 2000 rpm? I have an uncomfortable feeling about that.
was wondering why you just did not get 4130 ...IMO all the time it takes to stress relieve costs money .... also wondering what you would charge for something like this? Lawrence
They are asbestos simulated product made for the industry, with different manufactures and names. Most weld sights carry some kind of heat or welding blankets. ;{)---
Hi Keith, I was just following along in my Lincoln handbook, but I was wondering where you found that 8620 needed stress relieving whereas 4130 doesn't. Or was that just something you knew?

One heck of a weld job -- lot of concentration, preping and temp management. Great presentation Keith.
I'm hooked:D Think I was going through withdrawal waiting for part 5 over night:) Love the work and the format.

It figures, the best stuff always is! You should do an over view for those of us looking to build or modify our own. Love your videos.
I'm going to push the load button right now!
Thanks for the fast reply. Will be in touch with the supplier to purchase some in the very near future. Getter done :)
I'm just watching for the wood pile shots and stove stoking, but your camera work and dialog is superb, so I am thoroughly mesmerized by the fabrication! Thanks, now I'm off to Home Depot!
Great attention to detail on the pre heat.Another awsome video getting it done.
I´d say, this thing is definitively going to be better than new...!

I just watched this entire series for the 15th time. 😊
Your videos are always outstanding thanks for sharing
Great work Keith love the videos keep up the good work I appreciate you taking the time to show us how it's done

I hear you on the 5356 rods, had mine for years and hardly ever use them, good for parts that are getting anodized, but no need as of yet !!
Hell yes! Coffee and Keith. It's going to be a great day.
WOW that tracer attachment is awesome!!!
I have never had the opportunity to use one and didn't realize how versatile they can be.

Man! some beautiful projects and parts I could make on a lathe that big. Just no room in this small shop for something that size.
Great instructional videos Keith, thanks for sharing your knowledge & skills with us...love your channel, best wishes...

You are so honest, I admire that!
awesome, i got home just in time for this

Thanks for the comment! Even though the carbon content was close, to 4130 at least, within 5%, It had more to do with the added nickel in 8620.
;{)---
I encourage questions and comments, without your feed, I’m just a one man show! The speed supersedes the cost of having both systems. ;{)---

You might need to beef up the frame and/or set it up on a worm gear for mondo torque.
It is limited to about 27 ton, due to the ram and motor size. Built frame with 50 ton in mind! ;{)---
Henk.its because he can stick weld , . Not hot rod jockey all splatter and under cut . Nice one Keith.
Great welding. Now, post the next episode!
Thanks, Keith! Those were very nice strong looking stick welds! You and Jody make producing good welds using any of the three processes look very easy, but I know it's harder than you make it look!

Keith..please explain the "stress relief" of the weld thing!
Thanks
Dave
Thanks for jumping in with other sources for the same info! ;{)---
Hey Keith what would you charge for that? Thank you ...
hello from Brazil ...
congratulations on the videos are very interesting ...
One question: your hydraulic press, was built by at yourself, how many tons it works?
very good
Thanks Bruce! LOL Hey by the way, part seven is loading right now... ;{)---
Hi Keith! Professional work as usual! Absolutely fan from you, your work, your art of work. Can you tell me/us the titles of those two books you used? Greetings from Hungary!
@ 1:41 to 1:59, could you make a pawl to lock that gear for when you have to change the height of the bars?
If it was already 82 degrees in your shop when you started preheat and weld, it must have been well over 100 by the time you finished...that was a LOT of heat, good thing it's winter! Process question: you chose stick instead of MIG to ensure adequate penetration?
nice work !!!!!
What were those pieces you melted on the surface after heating ?
woo, i was a chef for 11 years.. i got into metal through knife making for kitchen minions. i wish them the best of luck. personally, i hope i never have to set foot in a professional kitchen again!
What brand is your press? I love that you can crank it up and down into place.
cant wait thanks
I'm curious as to why you left a small painted patch on the disk when you were skimming it.
Thanks for the comment! ;{)-----
I was combining the information's I frequently use, Lincoln book, my 1980's Emerson's buyers guide and the rod manufactures specifications . Most procedures are made of a collection of information on all components in the blend. ;{)-----
Why don't you use an infrared temperature gun instead of temperature sticks? Any advantages to temp sticks?
I came second , Nice work as always! Thanks Keith .
There is a big problem with these IR temperature meters. If your surface is even slightly shiny you wont get accurate reading. Try sometimes with polished stainless cooking pot that has boiling water in it. You and up reading something that is not even close to the surface temperature. Sticks work no matter what kind of surface you have.
why didn't you put the weld positioner on it's side with rollers holding the far end of the shaft so you could work on each side of the plate instead?
Keith, where can us faithful viewers get those blankets? I need several for an OxyFuel,Cast Iron welding job and the blankets I have from the welding supply,just melt!
Kieth, Are the blankets a special material?
After all that nice machining I would have used some anti splatter spray to keep it clean. You are a master. Would it have been overkill to put a woodruff key into the middle before welding it up?
Great chipping hammer
TIG welding it all would just have been insane! :D :D But I think, I would have TIGed the root pass. Just to be 101 % sure, I don't get any slag down there. :)

The Man is a Legend..
Keith, how much does the shaft and hub weigh together?
What book is that you looked up your preheat and interpass temps in?
Hey Keith, what was the name of that book with the steel characteristics and where can we get them? Thanks!
was wondering why you just did not get 4130 ...IMO all the time it takes to stress relieve costs money ....
also wondering what you would charge for something like this?
Lawrence
Hi Keith great job. I am Canada sowhat does this job cost and what is your normal shop rate?
picked it up that time....no sweat !!! how much does that puppy wiegh ?
You knew it was coming from me !!!! Where is part six?
Wow!!! What a cool change over!! I'm screaming this guy needs some help!! I guess not!!!
Why stick versus TIG? Just curious!
i like that hammer chipper
During that pre-heat I was waiting for the flange to expand and drop off.
...I HOPE YOU WEREN'T HOLDING YOUR BREATH-!!!
