🤣🤣🤣🤣 hey Mike B....when you can open your videos with "G'day" ain't a whole lot out there capable of raising that man's blood pressure or changing his facial expression! I bet he polishes that pipe back to mirror shine with the still beating hearts of a once pregnant crocodile.

@@soulsnatcher9228 when you heat compressed air the pressure decreases, also its generally high quality materials and you can watch what the metal is doing and stop WELL before anything bad happens
Mick is a Legend, knows his stuff, ex racer and bike mechanic took some big dents out of my sherco 300 pipe yesterday, came up like new. But yeah I know of people who tried to do it themselves and blew out the pipe so only get it done by someone who knows what they are doing.
I've done this with water. Fill up the pipe with as much water as you can get into it and stick it in the freezer, no caps are necessary. If the first freeze doesn't get the dents out simply let the water melt and do it again. It's really cool how it works and way easier.
I do this method but I use hydro pressure first to somewhat straighten the pipe if deformed then I use this method for the dents! I use the same clamps for both water and air pressure!
I’ve filled a gas tank with water, creamed a raw potatoe in the filler and stuck the tank in the freezer. Got the dents out of my tank. Could do the same, maybe, with the expansion chamber - if your freezer is big enough. Great trick. Thanks for sharing.
I was at Farleigh castle back in 82 as I lived next ti the track. It’s still there and still has memories. Noyce, Thorpe and so many others I filmed there back in 2010.
Had my FMF pipe fixed this way. If you don't your shiny pipe being heavily discolored from the flame, it's a great method. If I had a 2 stroke ever again, I'd get a non-nickel finish to avoid this and I don't care for shiny pipes.
Did this a few times back in the 80s after l was shown by a mate. Never a problem though l never used that much pressure. Pipe always sat better after dents taken out as it de stressed it as it returned to its original shape.
I have tried the freezer trick, fill up with water , make sure the low area with the dint is at the bottom of the water lever.put in big chest freezer, then watch, I check every 5 minutes once it’s close to freezing. And with big dints you need to let it melt, a bit to fill the dint depression then freeze again.
150psi compressed air and red hot metal (probably making psi closer to 180 or so). and no safety glasses, lol. legend. i wouldnt have the courage to do that.
Anyone mechanical seeing that done for the first time is amazed, only more amazing when you freeze water but that takes longer, is harder to seal and doesn't do as good a job......oh and it can burst the pipe if left too long, but freezing can work wonders, the tip was to seal the big end and pre-freeze that section up to the first dent, then fill the rest and seal the little end, the ice block made a better seal..... i guess you could also freeze the little end before the whole pipe, some pressure would always gets out.
@@GROVER3871 I use burning gear for a living and you can use either gas. The only difference is the nozzle. An acetylene nozzle is one solid piece whereas the propane nozzle is in two parts. As soon as he lit the flame I could tell it was propane. Propane is safer but not as hot as acetylene but still works fine.
Dean Pratley: Interestingly, I watched this video a this morning. th-cam.com/video/nLq3oZ0LfrU/w-d-xo.html It's a bit amateurish, but it's good for a laugh, and it DID work. (If you don't mind getting wet, it shows the weak areas of your welds!) The advantage of compressed air and heat is the ability to soften selected areas of the repairs.
What I do is get a pressure washer. Weld one and preferably the larger end then make a clamp to fit around the pressure washer nozel inside the other end weld that up then blast in the water it pushes most of the dings out to near perfect
Like magic, wow! So clever. Also the guy who fills with water and freezes the pipe, ha ha! Your minds are so creative. I have to fix multiple dents in a thin aluminum cover for very expensive speakers ($3200!!) and the covers are slightly domed. I'm doomed with the dome! No clue how to do this. I cannot compromise the paint job and any nick will show up on that white. Any ideas folks?
I invented a pipe repair kit that even had a pressure gauge on it and everything. My machinist passed away - and I can no longer find anyone to make the device for a good price. So, now it just sits on the shelf. (over 100 sold) :(
What most won't appreciate is that while he is making it look easy, it is a artisan skill that takes a long time to develop. He knows instinctively what heat/colour the material is at it's yield point and melting point - he stays between those two very tight tolerances while still guiding the internal air pressure to apply force in exactly the right place at the right time. Masterful.

I only use 20 psi still does the job. Not so loud if you over heat and pipe bursts not so load a bang. Glasses should of been covering your eyes not to of your head lol 👍👍👍😜🏴🦄🎣😁✌️
Do the clamps do anything else except hold the pipe in place? How important is this? Is that an air hose connected to the end of the pipe? Could have given us more information about the setup.
The air pressure pushes the dent out where the pipe is plastic (due to differential pressure like an inflated balloon). Too much air will make the pipe act as a bourdon tube, but relatively low pressure like 150psi won't cause too much permanent deformation. The clamps allow the zorst to be pressurised by capping the ends, one has a stabbing to allow the compressed air in/out. Hope that helps.
damm... don't go feel the pipe with your hand to see if its already smooth enough, i almost did from here lol man i got to edit,to say this: *GET* a deep socket and a ratchet/drill ---air or elec.--to do and undo those NUTS paleeeease!!! And what an excellent video...Thanks
air is compressible. Adding heat is making that psi rise. You essentially have a pipe bomb that could go off. Use water and water pressure, with 0 air in the system you don't have to worry about things exploding dangerously.
That's how I made mine small rubber freeze plus that I put a schrader valve in and a bigger rubber freeze plug up front. You do have to safety wire the front one in.

Greetings from Germany....
150psi compressed air and red hot metal (probably making psi closer to 180 or so). and no safety glasses, lol. legend. i wouldnt have the courage to do that.
I used to just fill my pipe with water and freeze it for a few days the ice expanding would pop all my dings out.
But if you let the exhaust too much tile in the freezer the exaust can break
S.C.DTDRD CREW ive never had one break in the last 35 years but i guess its possible.
Andys RV12 AM15 it is possible, happened on a pro circuit pipe of mine.
Spike Sta that sucks ass
How much do you think it really affects the power to have a small dent

Always a good idea to store your aerosol cans right behind the exhaust you're heating up with propane. Good job sir.
thats acetylene sir
@@phoenixvalkema3380 It isn't. Its propane. He says so himself.

I wonder if the psi Inside increased with the heat also, good job on the pipe, looks braw 👍
Bernard mathews : The PSI on the inside would only increase with the heat if there is a non-return valve in the compressed air supply.

I wonder how much the pressure increases with the heat, and decreases with the metal un-denting. Be interesting to put a gauge on it.
Ótima ideia 👍👍👍

Спасибо за видео!!!👍👍👍
Brilliant!
I use the hydro method and it puts the pipe back in mostly original shape and pops out some of the dent then I use this method to pop out the dent!
great mate how much does it normally cost of you took to a shop to do
Terrifying! I nervously waited for the pipe to POP the entire time.
Pretty cool always wondered how they get the dents out! Should be wearing safety glasses
Ok very good great work
Nice information. It looks like he almost leans into the flame at about 1:34 :-o
Brilliant
Excellent. does it work with steel tubes frame dents? i mean MX frames , dents we often find under the engine cradle?
If you pump the tyres to about 130psi these dents normally pop straight out.
Nice . I think i will make up some clamps and start doing a few jobs like this .

He's probably been doing this for more years than you have been alive.
Those water pumps are pushing 700 psi, I dont think 150 psi with some heat gets it above that.
150 psi is nothing. Your bicycle road bike runs at 150psi. Even if your have a week weld and it breaks its just going to make a hissing noise
so why do tires loose pressure when hot?? beside air compresses, water does NOT. you sir would be dangerous with half a brain...
@@jasonstalder5208 tires loose pressure in the cold not the heat. if you'd like give it a quick search
what psi ya got in there when doing the work as surle u woodnt wanna put 100 psi blow the welds appart
could you use rubber expansion plugs (freeze out plugs) as long as the dent wasn't too close to the plug?
That's how I made mine small rubber freeze plus that I put a schrader valve in and a bigger rubber freeze plug up front. You do have to safety wire the front one in.
Everything is just easier on a 2 stroke baby!!! BINGDADADLINGBABAING!!!
