I bought a shrinking disc back in the 1980s from a Japanese guy at the Pomona swap meet. It was called Sun something?. The way he demonstrated it was amazing. He beat up a fender with a hammer and used that disc and it took the dents out in no time. A true professional and a salesman. I bought it and tried it and didn’t get the results . With no instructions how can you get the same results.So I just hung it up in my garage as a display of a tool that I couldn’t use. Pretty much forgotten. Seeing your videos on it is making me understand it better. It only took 40 years. I was 18 at the time and I spent close to a $100 of my hard earned money on it and felt a bit suckered. I had a 1956 ford pickup and every panel was really dented up. Now I have a 356 in the same condition. It’s been rolled over and the front fender torn off. I’m making a fender with your flexible gauge system and it’s working pretty good. I was getting ready to make a buck and I found your videos and your system makes things easier Thanks regards Andre Tardif

[@proshaper]

You bought the original style Shrinking disc from Ken Sakamoto of Sunchaser. He bought the shrinking disc business from his mentor Scott Knight. He is still around. I too bought that style of shrinking disc from Scott Knight in the 1986. It has the ruffles on the edge and as you use it the outer edge turns into a serrated knife edge. I came up with the smooth and safe edge design plus mine are thicker and last longer. I also crested the first smaller 5" shrinking disc. The shrinking disc concept goes back to the 1930s. I have been making and selling my safe edge version now for over 20 years. Thanks for watching my channel, hope to be back soon. I have been super busy.

[@leslietardif4687]

@@proshaper Your absolutely right it is Sun chaser’s. I woke up in the middle of the night and remember it. He seemed like a really nice guy and he drew a crowd when he demonstrated it. So I bought it and thought it couldn’t be hard. I think he offered classes on it at the time but I just had enough to just buy it. I’m going to dust it off and try it out on my hood, roof and rear end of the 356 after I cut it out. I have done a lot of rust repair on all my cars in the past 40 years but never made a fender. Mostly floor repairs which any monkey can do. I bought this wrecked and stripped down 356 just because I didn’t want to pay for a nice one. A lot of hidden rust so that’s what I’m working on right and now and finally l am coming out of the rusty woods and just need the floor pans installed. Going to leave them out till I get the roof straightened out. Your videos are a great help Thanks for your response

[@strata99]

[@sportscarclinic]

Wray you are clearly a true master of a disappearing art. And having hand-worked many a panel over the past four decades, I won't deny the satisfaction that comes from doing a filler-free contour restoration, and the knowledge after the fact that the panel is as good as new. However... The chemical engineering that produces modern, high-end polyester fillers is in another universe relative to the "Bondo" that we used 30 years ago. I'm betting that that nose is still going to receive a coat of catalyzed glaze, or at least a round or two of 2K high build primer/blocking before paint. So the question is, apart from doing the service of maintaining the knowledge and practice of a disappearing art that saved a lot of lead back in the day, is it really "necessary" to straighten a panel past the point where the painter's "bag of tricks" will more than suffice to produce a perfectly straight contour that will most assuredly outlast the paint itself?

Yeah I have to say, right when he said he had it dipped the camera was pointing at at least 50 spot welds that will never stop rusting unless they rinsed it really well and treated every single weld with that sealer that will seep into the pinch weld and even go vertical around the weld. I personally would never dip something with a pinch weld or anything that is impossible to sand and reseal.

[@geofjonescustoms7332]

Nice work

[@ct71rr20]

Very informative video, thanks for posting this. I recently purchased your large and small disc set. I was having issues with the locking nut bottoming out on the inner flange that comes with the Makita (central hub support) before the 9” disc became tight. This would leave the locking nut above the surface of the disc. After trying numerous configurations, what I found to work for me was to use one 5/8 washer, then the 5” backing plate, then the 9” backing plate, then the 9” disc, then the locking nut. My 9” disc is tight now and the locking nut is recessed below the surface.

[@andysutherlandtaylor9012]

Firstly thanks for another video & merry Christmas Wray. A good instructional video on slapping irregularities out & using the disk. I will refute your sandblasting dislike though :). As a refinisher as well as a metal guy the best purpose of blasting is the key it provides. The epoxy applied over a good key prior to any finishing work, and sandwiching any filler or spray fill with epoxy greatly enhances metal protection over the years. I've etched E-type center panels with 0 warpage. Fine media ( worn 60+ screen nickle slag usually), nozzle angle, nozzle distance & blast pressure , experience & common sense are all required of course. Blasting to remove old coatings though is a no no. Aircraft strip, chem dip to reach bare metal first and it's not an issue. I will epoxy panels that I won't be working immediately post strip simply to protect from humidity & flash rusting. But it is nice to see you are moving towards another section of the E-bonnet. That was what drew me here in the first place. Thanks again!

[@diyautoschool]

[@Mercmad]

I agree with the Anti Sandblast sentiments having seen lots of panels on some ver expensive projects destroyed. Another pet hat is soda blasting, Especially if a car was blasted and still partially assembled. The damned stuff gets into corners and wiring looms causing a chemical reaction when electricity is passed down the wires. The only way to strip a car /boat/aeroplane is sheer hard work .

[@thecapitalalliance]

Excellent instructional video, thank you. Is that a slapping file you're using against the soap bar dollie, or just bent flat stock?

[@nathanschultz9088]

Hi Wray. I’ll buy the hub and nut if you start making them. The nut on my grinder doesn’t fit into the recess of the disc. I have two large discs set ups and a small one. I hope to get see you this summer for another class. Thanks for the videos.

[@georgeowen2083]

Because he’s using the shrinker as flatness checker and that’s not what it’s used for. Just because someone has been doing something for a long time doesn’t mean he’s doing it right. I am baffled to find out this guy is a supposed professional.

[@matthewmoilanen787]

Seems like there's more than enough things to sandblast that are better suited to it than thin ga sheet metal so sandblasters shouldn't be too upset. I don't know that I've ever seen a high end restoration or fab shop use a sandblaster on thin steel that it will deform so ya good advice Wray.

[@pitcuz]

Great video thanks, the part that I find confusing is that you want to shrink the highs and stretch the lows on one side, but if the panel is flipped over the lows are now high. If I use the shrinking disc it will be shrinking the areas that I want to stretch on the other side. That was confusing to type...lol

[@richardkaz2336]

around 15:50's I am assuming you are slapping around the marking perimeter of a hollow with the dolly underneath and when you work a hump you slap the centre of a marked area again with the dolly underneath.

[@Rusty63ss]

Another great video! I purchased both the 5” and 9” disc from you awhile ago. I am reshaping aftermarket panels on my car with the 5”. In a few spots I have overworked the metal and hardened it to the point that the disc is not moving the metal anymore. How do soften the metal so I can continue moving the metal around?

[@proshaper]

Never had the problem of the metal hardening. Maybe you are heating it too much. As long as you see steam 250 degrees or so you are hot enough.

[@Rusty63ss]

@@proshaper Thank you for the reply. I was going at it a little aggressively. Gave it some heat shrink with the touch and all seems to be better.

[@peterzinia3767]

Question Time! 1. When using the either size Shrinking Disc do you want the disc to be as flat as possible when making contact with the work piece? Or is it alright to use just a portion of the disc when making contact? 2. When you are using the Body Dollie with the Slapper where should the Dollie be placed? Dead center of the low spot or do you start on the outer portion of the low spot & work your way towards the center of the low spot? 3. When you are using the Slapper where should you be making contact with the work piece? Do you want to hit only on the outer areas or do you want the dollie to be directly beneath when striking? I believe it's referred to as contact & non-contact. 4. Wouldn't the Shrinking disc cause warping on newer cars that are made of Shitty thin metal? 5. What is the life expectancy of the Shrink Disc? Say an average of 4hrs use 5 days a week? 6. Can the Shrink Disc's be cleaned or smoothed of any build up? 7. Is there an optimal size/weight Slapper to use? Or is it personal preference? Any feedback would be appreciated.

Great Wray. When did you start on the shrinking disc method? Bought a set from you 10+ yrs ago and invaluable ever since

[@proshaper]

I have been using shrinking discs since 1985. I started out with Scott Knight's original ruffled edge style until 2000 when I came up with the 9" diameter safe edge smooth design, and the 5" diameter disc. I have been selling them since. I have several copy cats on both designs stealing from me everyday....

[@ianbuilds7712]

@@proshaper did you patent it? Can u patent it?.. It's a smooth disc on a grinder I bet the guy with the ruffled edge would say yours is a slightly modified copycat of his.. I bet his started as a smooth disc before he added ruffles lol.. the quality of your stuff is among the best but to say you're the only/first guy to think of that is silly. I make my own discs because the diameter and shape is a constant compromise... I made slightly bowl shaped one to get inside curves and I use it a lot...

[@jimgoodwin6440]

Good video, mostly. I wish you'd explain the positional relationship between the flapper and dolly as you're working the panel.

[@proshaper]

Mostly you watch the footprints left by the dolly slapper interaction. The only time you don't care about the footprints is when you are moving the arrangement of the metal, that is done with the dolly acting solely as a fulcrum, and the slapper as a lever. Arrangement is bending with no stretching.

[@Hitman-ds1ei]

Tried to find rust remover you mentioned on Amazon but failed to find it, could you post a link in description

[@evanlacey8592]

I found could loosen the nut a bit so the disk could spin and then turn on the grinder will self level works with metal polishing pads too.

[@ianbuilds7712]

That's interesting idea... I bet that works great.. because the threads fit loose so when you tighten it by hand it's always being influenced off center... I Sometimes do that when putting wheels on just for fun but I'm gonna test with an indicator someday

[@evanlacey8592]

@@ianbuilds7712 like the indicator idea but so many variables pads backing pads nuts grinder ect.

Can u use soap water for lubricant for shrinking disk

[@danielbuckner2167]

Haha, "down with sandblasting!" I like stripping the paint where the metal os good but if the car is pitted or bare rust as in a field find i prefer sandblasting so you can really get into the surface. I know Wray wouldnt waste his time on "ratty" cars but I think some are worth saving and stripper and rust converter just doesnt get into the pits like a good crushed glass wet vapor blast. Oh AND I also put epoxy primer on which Wray hates but all the metal work gets done before epoxy so i dont know why you'd do metal work afterwards. I get it for super high end cars like hes working on that will never see rain again in their lives but my stuff does as they are at least half daily drivers. Still so much to learn from Wray though on so many other techniques!

[@836dmar]

Wray, I notice the slapper marks show up in the low fields. Is this on-dolly? I supposed you would push up the lows with the dolly while slapping the surrounding ridge in an off-dolly manner. Sorry for the rudimentary question. Fascinating stuff. Merry Christmas!

[@proshaper]

Yes, it is both off and on dolly. Off at first until they start clashing together. Off dolly is changing the arrangement value. On dolly in changing the area value.

If you hit the back side of the dent with liquid nitrogen would it contract the metal on that side and help pull the dent out

[@scottprofitt1065]

So can you work harden the metal to where it will want to crack, or does the shrinking disc help combat this

[@proshaper]

I have never had an automotive aluminum or steel panel "work harden".

[@crzy11000]

I am sure there must be a optimal temp range for this procedure. Just a thought if you laser temp the metal when you are using the shrinking disk. It would give us a range of temp to get the steam effect. The laser temp sensors are cheap. For people watching your videos. Some people might be over doing it or under doing it. We have no way of knowing.

[@ocavant]

A spray bottle and water are even cheaper. Steam = good.

[@toodle171]

I have a Makita, you're recommending a Makeeter?

[@MrCbell57]

I've got a chance to use the wheels. Incredible. However I noticed if I try to shrink a small area I warm it up with the disk and then the metal swells and so I dolley it down. But I cannot get the swell to go back to where its flatter than what it was. I believe these places being on a fender of a 49 chevy truck had already been worked. But it appears they didn't do anything but stretch the metal outward. Maybe once stretched is why I cannot get it to go flat again completely. So if I do it several times the swell grows as always, then I hammeer it down and cool it with air, and it never becomes flat or concave as much as I need it to. I did larger areas as wel and found that I could not reduce the metal to where it was perfectly flat again. Seemed the swelling metal just gets bigger and bigger the harder I work! Perhaps too much working of this same stretched metal area? I'm using air to cool the metal after hammering it back to as flat as I can. No matter what though I still have a high that filler won't cover. I cannot reduce it with the heat shrinking disk. I did go back and take a torch to this same area and got it red hot in about several dime sized areas and those I was able to pound back flat. Just couldn't do it with the disk, no matter how long or how hot I got it, perhaps it never did get hot enough to reverse the expansion? Any suggestions would be of great HELP?

Watch my shrinking disc videos several times, there are three of them.

I spent $15 dollars in markers only to find out they didn’t work very well. Big markers won’t keep marking. They go dry. They didn’t last or work and it takes forever to cover the size of a hood. I keep alternating several markers but it takes so much efforts. Is there any other solution for marking the metal ? And having this lubrication? Also you basically are hammering down an already flat surface. The body I work in are severely high spots as much as 1/4 to 1/2 inch stretched high spots. The more I bang them in the further out the highs of the metal rises.

Ate you anti soda blasting too? Cuz that method is great in my book!!!

[@proshaper]

The problem is it gets into everything and it is difficult to remove.

Does sand blasting work harden the metal? Like shot preening?

[@proshaper]

Yes, I believe it does. The bodyman at my grandfather's restoration shop back in the 1960s would chew me out for sandblasting panels, I can still hear Franny today ("stop the sandblasting")in my head.

I did blasting for years, I don’t think it’ll work harden the piece, but the shot pinging is what warps the metal. Many people think it’s heat. If it’s done blasting shouldn’t damage the panel.

How do you approach a double skin panel like the roof on older Dodge pickup?

[@proshaper]

If you don't have access to the skin that is dented you can't do what I'm doing in the video. You have to make access.
