I can remember back 30 year's ago when I was repairing massey Ferguson tractors we had spray metal done on a transmission part that was cast iron it was new technology back then so we tried it to see if it could safe us some money but didn't work and ended up costing us more as we had to buy a new one . Its good to see that the technology has come a long way. Thanks Adam from Australia
YES cant get better than Adam with his flame spray kit on giving us all a glorious master class on how to do this right, also to keep a 64 year old Tractor going!!
Thank you for posting these videos on the Eutectic flame spray system. Because of you I have purchased a used RotoTec800 for work and between the manual and your videos I was able to rebuild several shafts for work. some over 1/8" buildup Spencer at Eutectic Canada was a pleasure to deal with, and the parts department is very knowledgeable and well stocked. I really like how the sprayed powder turns and cleans up
I love videos at the Old shop, it's just a great example of a working job shop and not a studio like the other one. I can't help it, it takes me back to when I first subbed like 10 years ago when you were making your bones here so to speak working out of this shop and doing some heavy cuts and great work, it just feels so much more authentic and relatable than the current one, that one just feels more like a showroom where nothing really gets done. 🤷👍👍
I have been in the oilfield over thirty years, we had an old mud pump that would get its parts flame sprayed once every other year. The place that did it went out of business and we had to scrap the jump that we couldn’t find parts for. Thanks for sharing.
Back when I was a welding inspector for a large boiler company, our welders would rejoice when we had Eutectic 7018 and S/S stick rods on site. The 7018’s were super easy to strike and flowed like butter and the S/S was the easiest stainless stick I’ve ever tried using. Been making a great product for years
Adam. When I was in High School machine shop 1967. Our shop teacher invited in a rep from Eutectic to demonstrate the equipment for us as students to show just what was capable with this technology. Oh, did I just reveal my age. 😁
Kurtis from Cutting Edge Engineering down in Australia recently did a piece like that using a new electric plasma spray machine he just bought. He used the gas flame spray one before that. Had I not seen that process being done, I would think such a thing could never work. I would have thought that the metal power would burn up before reaching the work and never adhere to it. That is crazy that it works.
The system CEE uses is able to do surfaces which will have pressure and rolling contact with hardened materials, hence the plasma. That material is laid down at a higher temp as well, CEE used a IR temp gun, remember the higher temp? Around 300-325°C instead of 300-350°F for Abom's unit.
Always wanted one of these. Very interesting to watch, not common to take that much care! That part left the shop in perfect order, hope you made money on it!
Adam, thanks for bringing my workbench to your shop for an hour. Have seen enough spray weld videos from you that I got some work done this time. It was fun listening and catching some spray weld shots now and then. Like hangin’ at a friend’s shop with no commute (but mute, except for this). Merry Christmas to you, Abby, and all of yours, Brian
It would be interesting to see a test piece where you tried to rip the layer off to see how well it sticks. Since it is not actual welding (the base material does not melt), there must be a limit to how well it can stick.
Hey Abom! I love your channel and have been a subscriber for many years. I'm just curious whether you read these comments or not. I don't always read the comments myself but I can't recall you ever replying to a comment.
Adam I really enjoyed watching this particular episode. It reminded me of some similar jobs I had back in the '90s. The job was the main shaft on a big horizontal bandsaw, bearing surfaces had been "worn out". When I went to turn down the bearing surfaces the metal just disintegrated into crumbs. So at one time these shafts had been worked over so I retouched the surfaces and welded and successfully remachined them. I did several shafts for them until I learned why the shafts were failing. The bearings were being over greased causing the bearings to heat up and swell and loosen up on the bearing surface causing surface failure.
Hi Adam Great job, I never saw a flame spayer before very nice, Adam I’m in the process of moving to Florida and I already have almost everything in boxes, I have some tool holders for an old lathe that a friend gave me and I have no use for these tool holders and I wouldn't like to throw them in the trash, if you're interested I can take them with me and I'll drop off just let me know Thank you
My impression is that the shaft itself never really gets hot enough to change its heat treatment. I think he mentioned that somewhere in this video... maybe? But with all the spray welding he's done, and the hands-on training with the supplier of the gun, the issue of heat treatment afterwards has never come up.
@@corylocher1Yup, several choices for the antique Adam traded up to and from -the newer ones give you a lot more control, powder choices, and heat zones with other specific companies providing a whole slew of choices for the vast number of jobs they can work with. In the beginning there was only this singular company though from which all the other ones emerged. The idea became the name of the company and is a whole industry of itself.
Is that material harder than the parent metal, this way it won't wear as fast as the shaft? Very nice fix and fitup...those busing seem like they will go a long way as long as they keep good grease pumped into it Keep em coming!!!!
I have seen so many of these videos and I actually now know how to get my Christmas tree straight. I pretend my tree holder is a 4 jaw and I go from there. Peace.
That Victor is a great machine, we have one since new in the late 80's. its done a world of work and made a lot of money. Taiwanese iron is good stuff. Just picked up a Hardinge hlvh-em knockoff from them used, no issues with it's quality either.
Great video, Adam. The last time i used a flame coating equipment was over 20 years ago, and it was a Jet-Coat. I'm curious if you cover the ways on the Monarch on the other side.
I have frequent wondered as well, but he has a fair bit of distance between them and by the time the over spray gets there it is just large dust particles he might not think another thing about.
Thanks for another interesting old shop job. . How do you compensate for the thermal expansion of the heated shaft? I thought the extreme pressure would ruin the live center but apparently not. The bearings in that center must be very strong to take that much heat and pressure.
My impression is that the shaft is usually warmed up to a couple of hundred degrees F, and that the material sort of fuses on rather than more like other welding processes. Then if the steel has a coefficient of expansion of about 7ppm, and about 3" of the shaft was hot at any one time, we get about 4.2 thousandths of expansion. That seems pretty reasonable, compared with the ordinary loads on a live center just from cutting. As to the temperature at the live center, I would guess there's not a lot of transfer to it, what with steel being a relatively poor conductor of heat. But again, it seems like there would be loads from normal (heavy) cutting that are perhaps similar to what happens with this process. Or... how do you see it? Am I far off base? I'm just trying to ballpark it to see if there's a reason to panic. I noticed that the whole thing didn't coming flying apart, or making funny noises, and he's used that center for this process many times before, so there must be an explanation.
Back in the day Canadian Families sent Massey Ferguson tractors to Cuba to pay ransom to Canadians captured in the Bay of Pigs Invasion. The tractors were shipped by rail from Moncton NB to Halifax NS and shipped by water to Cuba. This tractor would be of the same or similar vintage as the tractors sent to Cuba.
@@billsimpson604And most of those need repair just like these do, There is quite the thriving tractor shop work and need for more. Elderly (over 50) Machinist with practical experience are recruited from Florida, for those who do not spit at the name Castro. Retirement there was opened up recently by the Obama administrative department allowing fund to be dispersed to IRA owners who moved there. Good food from what I heard, the internet, meh, better here on the continental side. Old/New stock, from before Castro almost non-existant, so most everything is made from billet or DOM already there. Wait times can be long. Still better than Puerto Rico where everything has to be cross shipped via Florida and specific shippers.
At my last shop we can get anywhere from 2-2500 RA depending on customer needs! We wire sprayed up to 2500 RA on some parts for gripping or for surface plates to be walked on in oily/greasy environments
@ yes, it takes some work after machining to get it there but generally after machining you can get a 32 RA or better pretty quickly . Typical machined surface finish is around 64-125 ra!

It is only marginally better than the one he started with, the new units are very expensive by comparison and Adam hadn't developed as good a relationship with suppliers as he can now.

We do flame spray at our shop and have a procedure written by someone who worked in the shop 15+ years ago that we still follow. Degreasing is often not enough, you want to bake out the part before spraying it, do 300F for an hour then let it cool wrapped in ceramic wool.

I know I can Google this but hearing from a Pro who's been doing this kind of work for so long it makes the answer more special, but what make Emory cloth different from Sand paper?
The backing is actually a cloth, a bit like a thin burlap. It is far more forgiving of excess tension, and oil on the part. Like sand paper it can come with any of the common abrasives. The most common is aluminum oxide. Emory cloth is also more willing to tear in a straight line, where paper is usually jagged even when using a straight edge.
That opening photo is total steam punk. Would make a great poster for the merch shop. 🙂 That second grease hole is a mystery when paired with that narrow bushing. Maybe there's a seal that runs inside it, so it fills a reservoir around the shaft? Just wondering...
For a really marketable shot, he'd have to get his face right up close to the tool, turn off all the lights so the flame is the primary lighting on his face, and do this teeth-baring Billy Idol sneer
@@sccolbert whatever hardness you wish with these lesser heat solutions. There are powders to spray any number Rockwell C you want. This is not anywhere close to the temps needed for making something hard, with air quench or any of the faster methods to take the critical temp and freeze for later tempering like water or oil. It is a way to make metal adherence work for oil film conditions only. The process causes materials to bond at lower temps, around those temps used for tempering. It used to not be used for any rolling contact since that stress will peel the bond. This is not a molecular bond though such as welding, brazing, and the like. It is only for gentle contact such as is shown, oil film type. Since the 90's I think there have been solutions for repair of contact surfaces which need not only higher heat they need an atmosphere which allows a molecular bond. Plasma can be adjusted for specific combinations and usage, metals will be united. The systems which can do this are now closer to ready-to-use -they are sold as turnkey systems for specific repairs world over for example. Edited for typos

Hey Adam, are you considering a post grinder? Safer than using the cloth and a hell more consistent/better finish.
How does this affect the temper of the shaft? Does it need to be heat treated after?

But with all the spray welding he's done, and the hands-on training with the supplier of the gun, the issue of heat treatment afterwards has never come up.
Thanks for sharing this job with us, Adam.
Can a flame-spray surface be hardened if needed?
Some of them can, others do not like high heat after the spray process. Typically if you need harder you change to a harder spray powder

Could it be possible to flame spray the low spots of a lathe ways. And then hand scrape them flat?
It would flake off if you didn’t go through the process of fully preparing the contaminated surface to accept it.
@Inventorsquare of course but that would happen in any aplication. Maybe flame spray a piece of the ways is better than hand scrape two meters of ways

Why the threads?
It increases the surface area for the flame spray filler to adhere to.
Create the rough surface for good bonding.
When stressed the bond is less likely to fail radially
How hot does is need to be before striking the powder on ..?
125 degrees and 500 max during the spray
Looks like he's using that temp stick as a tester. If it starts to transfer then it's hot enough.
I'm a bit surprised you don't oven pre-heat to 280-300F "until the smoke stops"
