HOW TO INSTALL CORRECT METAL PIPING IN YOUR SHOP
When we first moved into our Canfield, Ohio plant, we installed all of our air lines with metal piping, being sure that the pipe size was correct for our needs, and correctly designed so that moisture in the air lines could be easily removed with water separators and drain valves. This is a necessity when operating any type of abrasive blasting equipment, plasma burning equipment or simple air tools. To see a very detailed piping diagram and other information on airline accessories, parts and fittings, please see:
One of our customers (Mr. EZ of Ringgold, Georgia) used the above piping diagram and airline accessories to install a neat airline piping system in his shop. Shown below are three pictures of his shop. Take a careful look of how the piping was installed with "risers" to keep the moisture within the metal pipes until it can be removed with our water separators and drain valves. EZ even has a neon "Open Sign" to welcome visitors.
Center picture shows the best way to install such piping. The main air line from your compressor runs horizontially across the walls of your shop. At each airline hookup station, the pipe drops down towards the floor with a drain valve to blow water out of the piping as shown. You can place a bucket under this pipe to catch the water when valve is opened. Just above this drain valve is a short length of pipe stubbing out horizontially and then an elbow facing up and another elbow facing to left. This section of piping is called the "riser" and is very important, as we are using gravity to keep the moisture within the piping below this area, so that most moisture can be removed when opening the drain valve (suggest daily).
Air is then directed into a moisture separator and then to an airline regulator, whch is used to regulate the air pressure from your main line to whatever pressure is to be used for your particular application. For most abrasive blasting in a Skat Blast Cabinet, we recommend 80 to 85 psi, as higher pressures will pulverize the abrasive on impact, eventually turning the abrasive into a powder form, which will not blast effectively, and will also create much dust within the cabinet, resulting in poor visibility. Looking at the above setup, see that EZ installed two moisture separators. Not a bad idea, although we would recommend that the second separator be a Coalescing Filter, which is the best choice for a final airline filter.
*Note: There are exceptions to the above suggestion as to pressure. If using "First Choice" or other lower cost abrasives and are blasting very rusty objects such as wheels or some heavy steel automotive components, you may want to increase your pressure above the recommended 85 psi. It will cut faster, but the abrasive will break down quickly, resulting in the necessity of changing your abrasive more frequently. Blasting with worn out abrasive is never satisfactory, as results and visibility will be poor.
Abrasives should be change on a regular basis and we offer many choices for various projects that you might need. See other section of this web site by clicking "Abrasives" at Home Page.
WARNING: Do not use Silica Sand for abrasive blasting, even within a closed cabinet. Sand is a severe health hazard, as operator is always exposed to dust when loading and unloading cabinet. Also sand breaks down quickly on impact & turns to dust quickly, so visibility is poor.
WARNING: Do not install any airline piping with PVC or plastic piping. Even though it may be rated at high pressure, it is unsafe and is banned in many states. Reason: should the PVC piping get damaged on impact for any reason, it will shatter and "explode", sending pieces of plastic in the form of shrapnel in all directions, with a strong possibility of personal injury. As an example, if you bump the PVC piping with a cart or any object, it will break. This is even more likely in colder climate areas. We have also heard reports of PVC piping systems failing after a few years, due to a deterioration of the inside surface of the piping from the oils that are commonly within air lines that come from your air compressor. There is a new type of plastic piping now being sold by TP Tools that has metal reinforcement built into the inside of the plastic to minimize danger of breakge under impact. Call TP Tools for more information on this new product.

"BUILD YOUR OWN CABINET KITS" are available.
These are described in TP Tools Catalog in detail at www.tptools.com
See below for a really professionally built cabinet that was made by one of our customers (Ken D, Westminster, MD). Using Skat Blast Plans and components and ordinary plywood and some metal legs, Ken was able to build a cabinet that will serve him well for many years. The nice thing about using Skat Blast componets is that they are always available at TP Tools in Canfield, Ohio for immediate UPS shipment. This means no down time.
Side view of Ken's Cabinet. Notice that he used two door latches, which is always a good idea to keep the dust created in blasting where it belongs. Floodlight was installed in the upper left hand corner - out of the way, but aiming at the work area in front of the gloves. Switch and duplex receptacle is on top left of cabinet and turns on the floodlight, and a vacuum can be plugged into the outlet. Ken opted for a foot pedal operation and added a very useful accessory - a blow gun inside the cabinet to blow dust of the surface of small parts. This is evidenced by the two air hoses entering the cabinet on right front (one to power gun and one to the blow gun).
Other then the legs, the entire cabinet was made of plywood. The lens, lens trim and glove and glove flanges were purchased from TP Tools at moderate cost. Joints were neatly aligned and sanded to where they cannot be seen and the cabinet was painted with light gray enamel, close to the standard color used by Skat Blast. If you look closely, you can see the inner lens protector, which is attached to the inside of the tempered glass lens. This protector is made of durable Mylar and can be changed as it gets scratched from blasting. These are sold in convenient packages of three and are always in stock at TP Tools in Canfield, Ohio
Front View, showing Power Gun and Blow Gun. Metal framework attaches to the wooden cabinet with either wood screws or bolts and nuts. Notice electrical outlet with switch at top left, which can be used to turn on the vacuum and light. A very professional job and with Skat Blast plans and components, you can make this very same cabinet, using regular carpenter shop tools. Not shown in this picture is a trap door at bottom of funnel, which is used for dumping used abrasive. This is available at TP Tools and is spring-loaded to keep it closed. Always remember to change abrasive on a regular basis, as blasting with worn out abrasive is one of the main reasons for poor visibility inside a cabinet, as well as not being cost effective, due to slow results. Most any abrasive can be used in this cabinet. See other section of this web site for a description and pictures of available abrasives that are in stock.
Side View - If we didn't know better, we would think this was one of our Skat Blast Cabinets! It is identical in appearance to our cabinets, including Gloves, Lens, Floodlight and Work Area Sscreen. As you blast, rust and paint are instantly removed and drop to the bottom of the funnel, along with abrasive. When foot pedal control is pressed, air passes through the power gun at about 80 PSI and pulls the abrasive from the bottom of the funnel and injects it into the air stream. This powerful blast removes paint, rust and scale quickly and efficiently. For small parts, we recommend the use of a hand-held "Bolt Basket" that holds the parts so that they do not become lost. This is not shown in this picture and if Ken doesn't have one of these, you can be sure that we will send one to him quickly. As you blast, the abrasive mix can be used over and over again until it turns to dust. At that time it should be replaced.
Congratulations Ken on building one of the nicest cabinets that we have seen, although there are undoubtedly many other similar cabinets, as we have sold thousands of "Build Your Own Kits". These kits are available in several types:
a) Trigger Operated Kit includes Trigger Gun, Pickup Tube, Siphon Hose and Air Inlet Hose, along with a clearly illustrated set of Instructions and Plans. Extra Nozzles are included.
b) A Foot Pedal Operated Kit includes all of the above, except that a Foot Pedal Control is included, and gun does not have trigger. This type of setup eliminates operator fatigue when pulling trigger for extended periods of time. Extra Nozzles are included and long-wearing Ceramic or Tungsten Carbide Nozzles are available at extra cost.
c) Trim Kits are available in several sizes and include Gloves, Glove Flanges and Gaskets, Tempered Glass Lens, Inner and Outer Lens Protector, Lens Frame with Gaskets and Screws. A Floodlight Assembly is included which includes a Duplex Outlet and Power Cord.
d) Cabinet Plans are included with all of the above kits, but are available separately at moderate cost and can be shipped via 1st class mail to U.S. and Canada.

When doing any blasting (outdoors or inside a closed cabinet) using sand is NOT an option that anyone should consider, due to the extreme health hazard (silicosis). If blasting outdoors and you are using an approved air-supplied hood/respirator, your exposure to the silica in the sand will be minimized, but positively do not allow others in the blasting area. Sand breaks down fairly quickly on impact and does not lend itself to recycling and is often not graded properly, which can cause clogging in the bottom of the sandblaster, as well as in the nozzle. Sand is often not kept in a dry location, so will not flow properly. Play sand is usually not graded much at all and can contain a lot of moisture, which will also cause clogging. Bottom line - do not use sand!
For blasting inside a closed cabinet, Glass Beads are the usual favorite abrasive, as they leave a "factory finish" on most parts. Crushed glass (also called, "Skat Magic") is also another option and looks about the same as glass beads (looks like salt or sugar). While lower in cost, it cuts faster than glass beads, but leaves a slightly coarser finish and can be a little dusty in use. Other abrasives that can be used are Silicon Carbide (diamond sharp & very expensive), Walnut Shells, Plastic Abrasive, Steel Grit, Garnet and other products. There are other special abrasives and abrasive mixes sold by Skat Blast (First Choice, Speed Bead, Fast Cut Max, and others.).
Soda Master Media can be used for blasting, but breaks on impact and can be used only one time (even inside a closed cabinet). Soda is recommended for engine parts, as it will not harm, etch, or otherwise damage the surface being cleaned. It is safe on chrome, glass, rubber seals, bearings, splines, valves, pistons and cylinders. Call for more information on Soda Master Media.
Keeping abrasive out of engine parts,is a hazard when using most abrasives, (other than Soda Master Media), so be sure to remove any and all traces of abrasive from engine and other mechanical parts after blasting. If blasting the surface of a vehicle, it is important to protect chrome, window glass, headlight and tail light lenses, engine and steering parts, under the hood,, brake drums, and other critical areas.
When purchasing abrasive, always ask the supplier if their abrasive is made in USA or imported. USA abrasives are graded carefully and most are to military specs. Imported abrasives may or may not be the same quality, or of the same consistency. Regardless of which abrasive you use, change abrasive on a regular basis, as visibility problems inside a closed cabinet will increase as the abrasive breaks down in consistency. Once the abrasive breaks down to a consistency of a fine powder, the fine particles will pass through most vacuum bags or cartridges, resulting in failure of the vacuum or dust collector motor, and often blowing dust into your shop. It is not economical to blast with worn out abrasive and doing so is one of the chief causes of vacuum motor failure.
Most popular abrasive for cleaning up carburetors and under-the-hood components, since it leaves a nice, satin finish which is very similar to the appearance when new. Commonly used on brass, aluminum, and most soft metals. Removes carbon, rust and scale from pistons, connecting rods and many other parts. Favorite abrasive for general parts cleaning and automotive use. Creates little dust. Grit Size: 60-80 and white in color, similar to salt or sugar. Packed in 50# containers and can be shipped via UPS promptly - always in stock for "Instant Shipping". This abrasive is sometimes included when you buy any of the larger Skat Blast Cabinets, since it cuts so fast and is generally a good all-purpose abrasive. Our Part No. 6700-50. Order at www.tptools.com A current MSDS Sheet is shown at bottom of this page - arrow down for this information.
Environmentally-safe abrasive is making a breakthrough in cabinet blasting. Made of recycled auto and other clear glass products, it is crushed by a roller-type mechanism to a consistency of 40-80 mesh. Similar in appearance to Glass Beads (shown above), except edges are sharper and in different shapes. These edges cut faster than glass beads, giving a medium texture to the blasted metal. Because paint and rust removal is fast, slightly more dust is present, but the results are fantastic. In stock for "Instant Shipping". While in color. Grit Size: 40-80, 50# container. Our Part No. 6704-50. Order at www.tptools.com
Cuts fast, yet leaves a relatively fine finish. and is economically priced. A popular abrasive for fast removal of heavy rust, paint and scale while providing a flat, fairly fine finish and with the advantage of having good visibility in the cabinet while blasting. Rounded grains prevent the abrasive from embedding in the metal. Produces a "white" textured metal finish, so important for primer and paint adhesion. Since this abrasive cuts so fast and is economically priced, it is often used for commercial and industrial applications. It is especially effective for paint and rust removal and can be recycled over and over again. First Choice is sure to be your favorite for painted and rusted automotive parts. Grit Size: 60-90, 50# container. Brown in color. Our Part No. 6710-50. Always in stock at www.tptools.com
This is a premium mix of abrasive that cuts 5 times faster than Glass Beads and leaves a similar "satin smooth" finish that is slightly coarser than if using Glass Beads. Highly recommended for general automotive parts cleaning and finishing. Contains a mixture of 80 grit Aluminum Oxide for fast cutting and 50-80 grit Glass Beads for a "satin smooth" finish. If you have been using Glass Beads, but want to speed up the process, give Speed Bead a try in your cabinet. Creates low dust and lasts long. Grit Size: 50-80. Silver in color. Our Part No. 6703-50 is packed in 50# containers and can be shipped quickly by UPS at www.tptools.com, or by calling TP Tools at 800-321-9260.
High-quality abrasive does not dull quickly, so lasts longer. Laves a coarse-textured finish. Longer lasting and more aggressive than glass most other abrasives. Comparing labor savings and long life, aluminum oxide is one of the most economical abrasives that you can use in a closed cabinet. Grit Size: 46, Brown/Black in color. Our Part No. 6702-50 is packed in 50# containers and is shipped quickly by UPS at www.tptools.com or by calling TP Tools at 800-321-9260.
