Sandblasting is perhaps the most effective abrasive technique that is open to you, and has a huge variety of different applications.  Thanks to the way that a stream of air carrying some form of abrasive particles such as grit or garnet is used, sandblasting can be used to strip almost any shape of surface of almost any form of coating.  One of the great advantages of this technique for an industrial or workshop application is that it relies on your existing compressed air system, and simply requires a small number of additional components such as a sandblasting pot to enable you to carry out a full range of blasting work.

The purpose of a sandblasting pot is to contain the abrasive material that is being used, and allow it to be fed into the stream of air at an even pace in order to provide the most reliable results and the best possible finish.  The main reason why the even flow is essential from a sandblasting pot is that this makes the whole system much more predictable in action, and allows the operator a much more accurate ability to estimate how the work is going, even when significant amounts of dust are present in the area that is being sanded.

Most sandblasting pots use a gravity feed system in order to supply the sand or other abrasive material into the air stream.  A compressed air line is fed through the bottom of the pot and this can typically be controlled by a switch so that the operator has control over when the sand is being forced through the system.  The main advantage of a gravity feed system is that the sand is allowed to flow through in the simplest way possible rather than through a mechanical system that could clog.

Because the sand or other abrasive material that is held within the sandblasting pot is sifted in order to ensure that all of the grains are the same size, there is little risk of them clogging up the feeder, and this ensures a nice even flow when the sandblaster is used.

There are a number of different sandblasting pots available to suit the various needs of users.  The main considerations that you need to make when choo
