Eutectic TeroDyn 2000 Thermal Spray Equipment, Mount & First Use 

RU-vid has been a pleasant surprise as a go-to for both entertainment and learning during this pandemic with very little to watch on TV during our down time. I have really enjoyed watching Adam's channel as I have always been fascinated with machining and fabrication.....I was lucky enough to actually do some hands on machining for two years during shop class in high school.....that's what hooked me. Thanks for sharing Adam, be safe.

Wow! It's amazing how metal can be moved, shaped, twisted, bent, go Adam, keep it going.

I am an SME (Subject Matter Expert) in the thermal spray field and enjoy helping people succeed in their goals. I’m happy to help anyone who asks😊👍🏻

ADAM, PLEASE READ THIS I work in thermal spray R&D, and I'm very concerned about your setup from a safety point of view. It didn't look like you were wearing a respirator for this work, and it didn't look like you have adequatr air extraction. The thermal spray process kicks out a lot of dust and fume, which gets absolutely everywhere, and it will wreck your lungs and/or give you cancer unless you put proper engineering controls in place. The 21031 is particularly bad, as it's a stainless alloy, and generates hexavalent chromium, which is a carcinogen. You do not want to breath that stuff in. The combustion process also generates carbon monoxide, and while flame spray is not much worse than just running a cutting torch, it put a friend of mine in hospital because he was doing it in an enclosed space without proper ventilation when working at a customers facility. Ideally thermal spray work would be performed in a dedicated spray booth, with air extraction that will pull 1 air change per minute at a rate of 1m/s at the hood, passing the extracted air through a HEPA type filter so it catches the dust. The ASM Thermals Spray Society has a free pdf on booth design, which I've used previously for speccing new spray labs. If that isn't possible, an LEV arm connected to an extraction fan would be better than nothing, and at least you can position it to catch the overspray. In both cases though, you NEED to wear a respirator when you're spraying, typically P3 or N95. Air fed is best, but a properly fitting half face respirator will also work, and is a lot cheaper. I hope you don't take this to be condescending or patronising. I love your channel, uou've taught me a lot, and I would hate to see you develop health issues from something that is entirely preventable. All the best from the UK mate, keep up the good work.

Glad I made it here before someone complained about welding a cart with bottles on it. Must be a fluke, I thought they just appeared as soon as you posted! Keep up the good work man.

Great video thanks. Felt wrong without the intro and outro music though Adam. Cheers.

I love how Adam's "test piece" looks like a work of art. Adam, you should offer it up to someone at random as a gift. It would make a nice benefit for your supporters or subscribers. Maybe split it in half down the long axis for two give aways !

Way back in the '70s we had a machine shop that used the same as your old gear, to build up and restore run-in inner bearing race location on Lotus Europa rear outer stub axles. This looks like a better system. Metallization saved thousands of total dollars for clients.

Not many people do spray welding, nice to have in your arsenal.

I've used a very similar Eutectic metal spray gun (not sure of model) to flame apply powdered nylon66 in a lathe to steel parts for rust and chemi proofing, or insulation. Various reasons. It works well.

hi adam if you use a round piece of body sheet the size of your 4 jaw chuck and cut a hole the size of your shaft slide it over and up to your chuck use 4 neomidium magnets to hold it to the chuck when you spray weld you get none on your chuck keeps that side of your lathe clean cheers from down under

Airbrush with fire... neat!

How many people are thinking, geez if I only knew this method existed I would have saved a lot. Nice work man.

Adam, glad you have the new sprayer. I first started watching your videos with you doing a spray weld job. Look forward to watching more content on spray welding. I don't weld but I do find the spray welding to be extremely fascinating. Cheers

I love tig welding, no annoying spatter.

Used those in 1980 and they save customers a lot of money.

I like the design of the old Soviet wire arc spraying guns. They are very simple, only requiring a welding transformer and an air compressor to work.

I used a system very much like this one to repair cast iron parts of 149 MTU v16s. The torch was like an ordinary oxy acetalin cutting torch with a socket on top for the powder bottle.

I'm sure this video will be as popular as the other spray welding ones? They are always a crowd pleaser. I must admit i like watching the metalising process. Keep up the good work Adam

With all your friends in the industry and creators you know it would be cool to see you guys make some original machines. It would be awesome to watch from the foundry to the machining. Cool stuff thought, keep it up!

Excellent work from start to finish as usual Adam, hope to see more of your great content soon!

I am working with a science lab who is working on cold spray welding. Takes the material to Mach5 with helium or nitrogen.

Wow, the finish came out way nicer than I have ever seen a build up redone before. and operation is smooth, enjoyed, cheers! Congrats on 462K subs, you the man Abom!

Agri-Tool & Supply is having a huge sale of their powders right now (About $3 a LB) :)

Thank you Adam I always enjoy watching your videos I am from South Africa

Hope you and Abby have a great Thanksgiving. LOVE THE VIDEO ADAM

Top tip. If You use open handles on the gascarrige and wind the gas hose in a figure eigth style You won't have to twist the gun....;)

Tony leaves his die filer always running and Adam does the same with his lathe :D

Abom79, I see that you have mastered the TIG gun. That looks like very good welds.

I never really cared for the Starrett digital stuff. The ones I've used always went through batteries very quickly. You're gonna make some people jealous with that Royal live center.

Abomb workin’ in the addition, yes!

I use the 21071 on just about everything. I love the stuff

Thanks Adam, great vid. Nice to see the comparison with the other gun. Any chance that when you do one of those future vids that you could film through a filter [I know it's tricky] so we can see the view you do, of the metal depositing on the surface? Thanks again. Stay safe, all of you.

Great setup. Works well. Great video. Thank you for sharing.

Amazing technique! Thanks for giving us mere mortals a view of Prometheus' forge!! :-D

I sent two terrodyne 2000 guns and a car load of castolin eutectic stuff down Florida way about a year ago, I hope this is some of it that found its way to you.

What would have been interesting is if you simulated severely damaged threads and cut the new ones off and spray welded it back to a diameter suitable for the original thread size and thread that, especially if you had an original nut to test

I used that system long time ago and it is very efficient!

As you Retire your Rototec I am just getting started with mine. I have near 50+ powders to play with.

Also note that this isn’t welding, this is a sprayed coating with a mechanical and somewhat Van der Waals forces bond. But many people call it “spray welding”. That being said, some of these coatings can be welded on via post heating to cherry red. He did spray and awesome aluminum bronze coating though; super nice 👍🏻 job 😊👍🏻😊👍🏻

Adam, Awesome really enjoyed watching thanks for sharing your video.!.!.!.

You really should wear a mask when making these videos... no, not because of COVID (there’s nobody else in the shop).... because you’re obviously a superhero!

Yet another great video, thanks for sharing the new piece of equipment Adam!

Both products very impressive!

Man you're proud out your equipment and I like it 😉

Beautiful work on the shaft!! Bravo.

i would like to have a look through some glasses when your doing a build up.

BTW: those bottles of powder for the spray welding look suspiciously like Cajun spicy shrimp/fish seasoning powder! Don’t get them mixed up! 😏

impressive stuff Abom! and, you need to smile more. you have a great smile. :)

Abom79 on a day that isn’t Saturday, woo!

Always wondered about this process, very cool process to repair worn metal...

Great job Adam, enjoyed watching and learning. Fred.👍👍👍👍👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻

My dad liked eutectic products, I’ve used the too, good stuff.

Found you from Trenton and Heath. Great channel thanks

Thanks Adam! Looking forward to seeing the spray gun in be action.

you have some of the coolest tools and toys!

I have a quick safety question for you. How long since the fire bottle was serviced? I used to service them. They have a nasty habit of packing. Vibrations in their environment and the 100 PSI or so tends to pack the powder. A rubber mallet tapping the base side, the shoulder, and then the bottom until the sound it makes is like a balloon. A bouncing resonant sound. This indicates it's ready for use. I have serviced many shops where they needed it, but it spit a little powder and clogged. I recommend a quarterly beating. :-)

Used to do machine work in a armature shop , did alot of metalizing with a metco set up. Enjoy your channel

Very nice, a worthwhile investment, it will save you money in the first few jobs.

Hi Adam, have you ever tried using the masking compound on parts for heat treatment in your oven to see if it stops surface oxidation? Instead of wrapping them in SS foil. Stay safe and well :)

I think that Terodyn will be the bees knees. Looks like buildup under a bearing race will make sleeves not so needed.

Subscribed hoping to see more of this spray set up. The torch mount on the cart places the nozzle close to the fuel hose. Maybe throw a tie on the fuel line to ensure it wont contact a hot nozzle.

Can you spray metalize things other than shaft for bearing or seals? How about a hard surface on something that you would mill the face on?

Very impressive equipment. Love your videos Adam.

Nice setup @abom looks great.

This would save a lot of money on axle shafts

very good video..thanks for your time

Great content Adam, I'm looking forward to getting my hands on one after the first of the year, that really is a nice unit I've been doing my homework on them and the alloys I'm able to use.

Wouldnt your high stepping welding positioner be better to spray weld on? I know you cover everything before and wipe down after, but...... you know.

That was great Adam - I always look forward to your videos! Thank you, and Happy Thanksgiving wishes to you and your family!

Could you do this again on a test piece showing what happens if you don't follow proper steps? One section with no preheat one section with no undercut and one section with neither preheat or undercut.

Such a cool process!

since learning about this process, i love hearin ppl say that phrase "u can always take metal away, u cant put it back..." :p i didnt always know about the spray welding process, but i have known about welding for a long time n have always wondered how that phrase became a phrase because weldings n additive process.. even before that there was soldering.. so thats always been a strange phrase to me

Nice job as always Adam. I want to get one of those to practice with to see if I can build up a crankshafts on old farm equipment

That would be awesome for repairing hydraulic ram cylinders that have pitted. Make it all new again. Lol👍👍

I used one of those thermal sprays back in the early 80s, I think it worked ok , but its been a long time ,

No opening music? just right ta business! no messing about!!!!!

How hard is that surface when your done?

Makes me wonder what the impact of electric power steering has. In a straight line it shouldn't be pulling any amps.

Used this flame spray gun many times. Then did the fusion

Nice additive process in a trade of moving metal. Im sure you know this but a Y connector would let you have your cutting or brazing torching hooked while your gun is still attached. Great vid

I am surprised you did not machine a relief into your shaft so that when you tightened the finger screw T handle you would not scuff up the shaft so you could not remove the spray gun?

Nice addition to the shop there. How are you liking your new royal center? I can remember when you showed that, you were happy to get it.

One of baddest tools in the shop. ✌

I see some over-shaping and metalizing of the steam-stoker engine coming in the future!!

Am I seeing more smoke than the old gun or am I imaging things? The old one had a lot of particle flying around, this is more like a solid yellow flame with dark smoke. Looks different in my eyes, but if it work, all is good.

Good demonstration Adam, Thank you

after getting familiar with tig i flinch every time you spark up

Nice gas flow meter !

Nice piece of kit man. Spray welding is awesome to see, And that cylinder came out great! I noticed you switched to 60p videos and it's giving me a choppy bar in the middle of the screen now. Makes it harder to watch than 30p. Not sure if it's on my end or yours tho

What a great video Adam thanks for putting it out there for all of us to see I have a question about how you determine the RA finish on things that you machine on your shaper or The spray welding

adam.. any chance of screwing some gator clips to the ceiling behind the lathes.. so you can hang a fiberglass welding blanket from the ceiling to protect anything behind the lathe..

Looks like it did a great job.

Just an observation, could you make a handy dandy holder on the lathe to hold the gun like you did the cart? I know you'd still have to swivel the gun for even heating but it might be more even heating? I'm in no way a machinist

Would that process work on the stroker engine? if the welds that are there do not hold up

god damnit i love that tool. it will be quite a while before i ever get one lol but the lust is real

it would be a cool experiment to try and build up material on the threads

Very cool stuff!! Love that metal spray!!

You gotta love new tools!

I've always heard the term "Spray Weld", an always wondered how they did it. Thank you for easing a curious mind. That's really cool. Now, would they use this on an engines crankshaft?
