Podiums with his own hands in 2108
Many people know how to make the podium for the "textile" technology. If we judge by the information that comes in late, in the manufacture of professional and amateur designs the technology pushed more labor-intensive and sophisticated technology. In applying these technologies is used polyurethane foam. And yet, this technology early to write off because it can easily make podiums without special fitting. You can make perfect in its form podiums. This can be seen on the example of making the podium, designed for the WHA 2108. To begin, we take 2 rings, the height and diameter should be slightly more tweeters. This is to ensure that it is possible to install them flush. Then we take: epoxy, sewer PVC pipes (50 mm), a piece of knitted material, hot melt glue, sandpaper and filler having a composition of glass. Also need vinyl or antigravy with paint Eska 5104, which can be used as a decorative material. First we need to clean off coating from the surface of the rack. To do this, use the medium grit sandpaper. Pre-defined ring binds in the appropriate places melting. The resulting product should obtyanut piece of knitted material. Then sew the edge and gently span fabric. Now it is necessary to dissolve the epoxy. At first glance this procedure seems to be very simple. But in reality it is not. If Nedolya hardener, then freezing will last very long, and if it is poured - the resin will be very fragile. Do not rush to apply resin to the surface. First drip it onto paper, nagreem tile or a soldering iron. If you lit it properly, gum boil. When the resin has cooled, it could easily be broken. If not, add a little more hardener. Saturate fabric with epoxy resin. Do not forget to leave a site in the center of the circle without impregnation. It is necessary to avoid bloating. Typically, about 30 grams of resin impregnation Half will go to. You can add a bit of aluminum powder, which is also used as a hardener. This will help identify possible defects on the surface and contributes to better handling. Once the resin hardens, processed drips from her soldering iron and sandpaper. Then cleaned out our product. At the same time try not to get to the tissues. We cut a hole for the speaker, and caused filler. Putty should be applied fairly thinly. Then we clean the sandpaper. Decorative finish is as follows: pre-degreased surface, applied several coats antigraviya. As a result, we obtain a surface that looks like shagreen. Treat the surface composition Kerru KR-970, after which the surface is similar to plastic, which is used to facing. Dyeing, the podium after starting to dry completely antigraviya. For this we use the paint Eska 5104. Paint color is "graphite" and "black". It is designed for painting plastic. The only drawback - the lack of aerosol packaging. If you do not spray, use the Dupli-Color cartridges or VHT. They are painting a dark gray color, suitable for painting vinyl and plastic. After staining the dried product and make the necessary hole for the wires. Then install the tweeters in the sealant, plug and consolidate their structure in the car.
