A line striper is attached to a vehicle with a two point hitch and has a swivelable rotatable wheel mounted thereunder to support the striper on the ground. A main beam is releasably clamped and may be slid from side to side depending on operator preference. The gun boom may then be located on the desired side. A delay feature on the control allows the operator to look ahead on a sighting camera and pick the point at which he or she desires striping to start (or stop or any other operation). The controller then compensates for the calibrated distance between the sight point and the spray gun and then starts and stops the gun at the appropriate time given road speed.

A needle assembly for an airless spray gun is provided with a needle which is centerless ground and electropolished to greatly increase life. Further life enhancements are gained by use of a plastic needle bushing in the needle clamp and provision of a specific length to diameter geometry for the needle yields enhanced life as well.

A coupling is designed for use in connecting two shafts such as, for instance, the output shaft of an engine with the input shaft of a pump or similar device. The coupling is formed from a generally cylindrical body having a central bore, the bore having a keyway therein. Dyametrically opposed from the keyway, a radial split is formed in the body of the coupler and the split is bridged and releasably tightenable by one or more bolts or other such fasteners.
