Spray Gun Agitator

Spray Gun Agitator

A new product that I found to be most helpful when spraying a finish or other things that had to be in complete suspension to assure uniform coverage, is a agitator siphon cup assemble sold by N.A.P.A. auto part stores. This cup will work on most major brand guns. The 1 quart cup provides constant agitation from air right off of the same line that your gun works off of, no extra line is needed. You can control the mixing speeds of the agitator, and does not require an extra cleaning. The part number you need to ask for is model 70-707. This may be of big help to those of you who do a lot of finishing work.

Neck-to-Body Joint

This method of joining the neck to the body was discovered by a violinmaker friend and is effective and reasonably easy to cut. It’s basically a straight mortise and tenon joint with an angle (a) added, which gives it a locking effect like a dovetail joint. The sides of the tenon are cut and the angle a is cut. If a tight fit is managed with the female section in the heel block, it makes a reliable joint.

Glass Jars for Spray Guns

Glass Jars for Spray Guns

Commercial spray guns, such as the DeVilbiss type MBC, typically use aluminum cans to hold the juice. Aluminum cans are lightweight and unbreakable. They are also expensive and inconvenient, in that they must be labeled; the contents can not be viewed without uncorking the cans.

By substituting glass jars for the aluminum cans, many advantages can be realized:

Jars are cheap.

Jars are clear, allowing one to observe the contents instantly, and to check for sediments, precipitates, jungjills, farfles, and other forms of grungus.
