| What are Shrinking Discs?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 |
| How is it used?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 |
| 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 |
| Which size disc should I get, 3", 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 Our newest addition to the shrinking disc line is the 3" disc. The SD3 Disc and Kit were designed to compliment the larger shrinking of purchase. The discs themselves will last a long time, long enough that we don't have an actual lifespan to give you, and since usage varies greatly for different people. The only reasons you may choose to purchase spares are, in case you drop and bend or otherwise damage a disc, loan it to a buddy and he fails to return it before you need it (heard this more than once!), or the primary reason being, if you are planning on using them on multiple different materials such as mild steel, aluminum and stainless steel. You can use the same disc, however you want to be sure you clean it very well to prevent the possibility of embedding tiny steel particles that can rust or cause corrosion into your stainless or aluminum panel. To prevent that from even being a possibility, it is recommended to use different discs on different materials. |
| Why choose our "Easy Shrink"™ Shrinking Discs over others?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. Brian Wolfe (Owner) is the Inventor of the smaller stainless shrinking discs, the correct 4 1/2" size in particular (as well as the new 3" disc), but was then followed by others. The larger discs have been around for ages, made by multiple different manufacturers in several different styles. 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 larger one and for use in 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. We have also worked hard to improve the quality control checks following manufacturing before delivery. I, Brian Wolfe, will personally provide great friendly customer service to deal with problems or answer questions with quick responses with an importance to customer satisfaction. We have also put alot of time, effort and testing into making reasonably priced quality "Kits" that generally include everything that you need to get started easily and conveniently with the least amount of hassle. |
