Thanks for the demo of how you use this tool on steel mate. You've got another subscriber from this one, now I gotta check out your other vids as I work my way along my own restoration!
Thanks Matt. These videos are done in one take only - no prep, no edit, completely raw footage on a grungy old workshop SLR Camera. Shot by my daughter Bonnie. I need better filming equipment but cant afford it. ;-)
@@streetneat of course hd videos are awesome but I would rather watch a video of someone knowledgeable giving great advice than a flash edit Haha keep it up. Already hanging for next one 👍🏾
This is true; many will put great emphasis on production and the actual presentation information gets drowned out. I am of the firm opinion there can be artistic licence in story telling that doesn't overwhelm the point being put across. I do need to invest in better equipment if Im to do more of these videos. All donations gratefully accepted hahaha.
Many thanks for this lesson. I had a flat section of guard about 2 feet square covered in high spots (caused by heat shrinking to fix oil canning) that I was beginning to doubt my ability to get right. I had tried the shrinking disc (with no success) after watching some other videos. Then I watched yours and had a real Eureka moment. After about half an hour using what you showed me, I reckon it will flatten with a couple of coats of epoxy primer. Thanks for helping me keep my enthusiasm up.
Sorry it has taken me so long to find all these comments. Im glad to be of help as that is 100% the entire point of doing these videos. No one taught me the shrinking disc secrets either so I have had to nut this stuff out over decades and like you one day a Eureka moment and suddenly it all makes sense.
great video thanks. So how would you tackle a MIG welded panel differently? I have exactly this problem where the weld is much harder than the surrounding panel.
'Mig welds are harder than the surrounding steel so planishing via hammer on dolly them will result in shrink/drawmarks directly around the weld itself. The trick with a Mig weld is to aim to reduce the weld size as much as possible through linishing/ filing and dont heat it up too much while grinding. The shrinking disc has been successful in reducing the weld warpage but man is it super slow and tough going! Mig welding will penetrate and droop through the weld join. Tig and gas welds dont put heavy deposits of weld on the opposing side.If you can only get in and linish one side then understandably you will struggle with shrinking the weld down itself but you will be able to straighten out some of the warpage in the surrounding panel with the shrinking disc.
If you can get a piece of copper behind where you're welding it helps a lot... I leave a small gap (thickness of my wire) between the new and old panel and really just tack as little as possible and get the copper away asap... The copper helps take the heat away, stop the weld from falling thru the seem and gives you a place to focus the weld. basically i weld directly into the copper and let the puddle expand into the steel then pull copper away immediately... Mig welds can also be annealed as well and doesn't really require a lot of heat just patience..
Great job mate, love it. Can this be applied to metal over stretched from English wheeling too much in an area of metal? Basically i've gone too far in one area and need to flatten it out a little. :)
sorry for the delayed reply - RUclips wont let me see comments and I just worked out they hide them for review - but only some comments... go figure! Yes, absolutely and I have done the same myself.
a bit confused. you said the low spots are a result of a weld that has shrunk the metal. so shrinking it a second time w/the disk brings up the surrounding low spots? i can only guess there is some kind of normalizing that happens when you add the wet rag to cool it. could you please elaborate on this a bit further? thanks very much. E.
The welding causes the metal to shrink and pulled up into a high spot- which drags the steel around it and causes a low spot as the metal draws up. I explain this in the opening scene. Watch the video a few times and it may start to make sense. The disc will as you say normalise the panel as it is hammering away and ironing out. The rag will shrink the heated steel from the disc quicker and allows you to see the metal pull up the lows and flatten the highs. I know this may still not make sense but try it and you will see it actually works.
I'm confused for the same reason. I was taught to stretch the heat affected zone after welding, because the shrinkage will (as shrinkage always does) reduce the amount of surface area. After it's stretched back out it should all be the right area again and the warpage should be gone. It needs to stretch, so I don't understand how shrinking the lows and reducing the area even further will help.
I generally have some chill tunes running in the back ground streaming on youtube while I work. It could be Air or Thievery Corporation - or what ever is next on the playlist hahaha
Its hard to say how long its been around as its something I worked out by myself. However I would say Im far from the the first to use these sorts of techniques Im sure.
Its no different to learning not to hit your thumb with a hammer - you learn to keep bits of yourself out of harms way or pay the price! The beard has been caught up a few times in spinning tools and set fire to. It grows back. I learned to not let it get in the way or put myself in a position where its likely to be caught up.. I also learned not to hit my thumb with a hammer after doing that more than a few times.
Thank you for this info; I need to fix an oil canned fender on my 70s Challenger. With all due respect to you and all others with beards and long hair using power tools, running and working on machinery; CUT IT OFF.
Yeah Im new at this- only been doing this work since the early 1980's. ;-) The whole point of this video is to help those that are still developing and showing the strategies and techniques I have learned helps over the decades.
@FredBlair please do share your video demonstrating your highly developed welding skills.....I am sure everyone would be interested to then offer their own useless opion back to you. Wow... clown.
And when he's not working metal, he's making toys for children all over the world.
And Playing In ZZ Top
been in the game 50 odd years and never heard of that.Evey day I am still learning even at the ripe old age of 69.
The joys of getting old is always learning new tricks and techinques. Its what keeps me in the game myself.
Brilliantly done and clearly explained thanks
Really cool, I'm a hobbyist & that makes a lot of sense to own.
Thanks for the demo of how you use this tool on steel mate. You've got another subscriber from this one, now I gotta check out your other vids as I work my way along my own restoration!
Thanks for subscribing. On the good news front there will be a whole bunch more videos coming soon!
Thanks mate for the great information you do a good job
I have had one for a long time but never used it... Thanks!
Nicely done+ explained!
Glad it was helpful!
Excellent video. Thank you. Subbed!
Another great video keep em coming!

Thanks for the video! Do you have more information about that disc your using?
The inventor, Wray Schelin, sells them through his site.
Wray sells them yep as does Ken Sakamoto. Mine was made in Australia by a guy who no longer makes them. Its lasted me for decades!

That seems to work great. They are crazy expensive though :/

@@streetneat The panel is round. You said that. Taking length from a curve flattens the curve.
Where do you get the shrinking discs from?
Wray Schelin from Proshaper does a good range of discs - look him up on face book or here on You Tube.
Great video, what is the background music?
I generally have some chill tunes running in the back ground streaming on youtube while I work. It could be Air or Thievery Corporation - or what ever is next on the playlist hahaha
@Ethelvino Zanchet You cant please all the people all the time. No one is forcing you to watch my videos.
Annoying?
I’m just a novice at sheet metal body work, so is this technic new or has this been around for a while?
Its hard to say how long its been around as its something I worked out by myself. However I would say Im far from the the first to use these sorts of techniques Im sure.
What if gas welding is all that’s available to you?
I would aim not to be in that situation. Different tools for different jobs . Gas welding is fairly universal but has its limitations.
respect tne beard bud but wow you can work withit around a grinder respect sir bet fire is different story eh ha ha
