Wolfes Metal Fabrication is a real, Insured and registered LLC Business, what about them? Watch out for other ribbed hard plastic backing pads that include a Cast nut!I have seen them break! Our Kits use machined nuts very important for safety!
No one else offers this! Watch Our Original Video Demonstration! In the above pictures and our original video, I demonstrate removing two large bulges in a domed panel, which simulate dents that have have been popped back out, but remain overstretched.Once I got the lumps shrunk back down (I did NOT use a hammer and dolly, only the shrinking disc for demonstration purposes), I ran a sander over the panel to show exactly how smooth of a finish can be achieved. You can not tell the damage used to be there, and if painting, it would be ready for primer, no filler needed. In normal conditions, you would straighten out the metal like usual with a hammer and dolly first, to speed up the process, and then use the shrinking disc to achieve smooth final finish. More details and instructions can be found in the included instruction manual. New High Definition Repair Video on a 1941 Lincoln! Just a few of our customers comments on our Shrinking Discs. The shrinking disc works fantastic, even for an amateur!! Been doing paint and body 25 years. A definite must have for fabricators!!! Amazing, I have been using a torch for 35 years, this is the way to go Thanks 4 the AWESOME tool! It's the most-used tool in our shop!
Our "Easy Shrink" discs are made using a Special High Grade Stainless Alloy & Manufacturing Process, that creates a long lasting, low galling, crack resistant, safer and higher performance disc compared to older designs. Works on steel, stainless, aluminum, brass. Creates Heat through Friction to allow shrinking of the sheetmetal. Works with compressed air or water cooling (spray bottle or rag). Is good for shrinking, smoothing, blending and relieving surface tension created from damage.
Have sizes and Kits to fit standard 4 1/2" & 7" or 9 sander/grinder/polishers. 4 1/2 Discs, Recommended RPM 10,000 - 13,000, Max RPM 13,300. 9 Discs, Recommended RPM 3,000 - 6,000, Max RPM 6,500.
When using a Shrinking Disc, you are able to shrink overstretched areas and repair damaged sheet metal panels to a like new condition, making for a better quality, longer lasting finish with little or no body filler at all! The secret to them, is they create the heat that is needed to shrink through friction. They produce better results and are much more controllable than shrinking with a torch or a solid tipped stud gun. When using a torch, you are directly controlling how much heat is being inserted, and were it is going.
This is easily and many times overdone, resulting in warping and further damaging the panel. With the shrinking disc and its large surface area, it eliminates some of the guess work, especially when smoothing a lumpy panel by only touching the higher overstretched areas! The heat is also more concentrated on the higher peaks of the damage and tapers off to the lower areas, which results in a much greater accuracy of heat placement, in turn ending with a much smoother nicely blended panel. Once you have started using the shrinking disc and get a little practice under your belt, it will make you feel more confident in your metalworking skills when you can finish a panel with no body filler at all!The more you use it, and the better you get, the less filler you have to spread and sand! It saves lots of time on sanding, keeps the shop cleaner from having less putty dust, and makes for a better quality, longer lasting finish with little or no body filler at all! In normal conditions, you would roughly straighten the panel, tap the dents and low areas up with a hammer and dolly and then make a couple of passes with the shrinking disc, heating and cooling. Look over the panel to determine were more work is needed, and using a hammer and dolly, rearrange or tap up any remaining low spots followed by a few more passes with the disc. After completing several loops of this process, your panel will be smooth, and back to normal surface tension. When using the shrinking disc after welding in a patch panel to arrive at an almost invisible seam, you should start by carefully grinding the bulk of the weld. While doing this, you want to minimizing excessive heat buildup and prevent thinning of the panel itself. Then the HAZ (Heat Affected Zone, the area that was discolored while welding) needs to be stretched by using a hammer and dolly (with slightly more contour than your panel), striking the hammer "On Dolly".
This is required, because the welding process heat causes shrinking just like the shrinking disc does, although it happens in an unwanted and uncontrolled manner. After stretching the HAZ, it will be closer to the original profile, but still lumpy, uneven and possibly over stretched from the various hammer blows. Now is when the shrinking disc works its magic. By using the shrinking disc over this area, and blending around the edges if needed, it will only touch the higher overstretched areas as mentioned before, and shrink them down so the entire weld area is smooth, and has the same surface level.
More details on using the discs included in the Instruction Manual. How does Heat Shrinking work? Shrinking occurs after heating (causing expansion) and cooling metal (resulting in contraction). This happens because while a panel or sheet of metal is being heated, the heated area is trying to expand. The surrounding cold metal is containing the majority of the expansion and holding it in, preventing the expansion from happening.
When cooling the panel, the heated metal contracts which the surrounding metal cannot prevent, in turn shrinking the heated area. Important aspects of this method are heating and cooling fairly quickly. Slow heating is usually more of a problem than slow cooling, as it will let the heat disperse into the entire panel before any expansion containment has taken place, reducing the shrinking discs effectiveness greatly.
If heating happens quick enough, some shrinking can occur with only room temperature cooling, but is greatly accelerated and multiplied by cooling with either compressed air or water (squirt bottle or rag), but water generally tends to provide quicker cooling. These shrinking discs work well on steel, stainless, aluminum, brass and may on some other metals. (it is recommended to use separate discs to prevent cross contamination) Also it only touches the higher overstretched spots that need to be shrunk. So you are able to shrink an area on a panel without worrying about making the problem even worse like you can with a torch. The shrinking disc also works excellent on removing those "oil can" dents that were caused by overworking and stretching the metal too much!Which size disc should I get, 4 1/2" or 9"? The small 4 1/2" disc has a low initial investment (almost everyone has a 4 1/2" grinder), and works great on small parts (for example, stainless trim, grille shells, motorcycle tanks, etc), light damage, tight spaces, or after primer and block sanding, it works great for catching any high spots that were overlooked, instead of beating them in and covering them with filler, without disturbing much of the surrounding primer (as it is more difficult with the large disc).
The large 9 disc excels when working large, low to medium contour panels such as, hoods, roof, door, trunk or heavily damaged panels, because of its greater working surface area. Compare it to block sanding, were on a large panel, a longer sanding block makes it straighter and works more area at one time, but the small ones still work and are needed for some situations as well. Why choose our "Easy Shrink" Shrinking Discs over others? Brian Wolfe (Owner) is the Inventor of the smaller stainless shrinking discs, the correct 4 1/2 size in particular, but was then followed by others.The larger discs have been around for ages made by multiple different manufacturers in several different styles, and over the years of using and providing shrinking discs, we have made changes and improvements to the material and manufacturing process that we use, to provide you with an improved quality, safer and better performing disc, as well as introducing a smaller size disc to compliment the large one and for special situations. Many people prefer our smooth shrinking discs over the wavy discs for several reasons. It is safer with the flanged edge than the "saw blade" like edge the wavy discs have. The ridges are not necessary, they create unneeded vibration and noise as the shrinking happens because of the heat caused by friction. The ridges can actually lead to premature failure and cracking due to wearing thin only on the higher raised areas of the disc.

When will I get my item? US orders usually take 2-3 days but allow 6 for delays. Do your shrinking discs come with a backing pad?
What type of backing pad can I use for your shrinking discs? Most large grinders come with a rubber or plastic pad that is intended for flexible sanding discs, and have a nut that is tapered so it will sit flush with the surface when tightened. Some pads may not follow the contour of the discs well and will cause problems when mounting, which is why we now offer both sizes of pads, both of which fit the discs well. I love your tool, and would like to tell you about it.
