What Type Of Porter Cable To Purchase?


Recommended Posts

A US power tool company, Porter-Cable established in 1914, began manufacturing an electrically operated Variable-Speed Random-Orbit Polisher for the wood working industry in the 1990s. It is now one of the most popular tools used by professional and enthusiast automotive detailers.

Often known by the companies initials PC (Porter-Cable) but also called a ROB (random orbital buffer) or DA (duel action) polisher

There are two model numbers 7336SP and 7424 both machines are identical, but they come equipped slightly differently. The 7336SP, sander polisher comes with a 6-inch counterweight; Porter-Cable outfits the 7424 Polisher with a 5-inch counterweight and a 6-inch foam-polishing pad, PN 54745.

Alternative products-

a) A European (Germany) equivalent to the PC 7424/7336 is the Flex X1107VE. http://www.baukreis.de/produkte/inde...p=FX&s=&pg=199

B) Bosch Gex 150 Turbo 150mm Round Orbit Sander 240v –

To polish the paint film surface with a random orbital polisher requires a backing plate, a Velcro-backed foam pad, and a machine polish. The variables are; orbital speed, pressure applied, foam pad composition, whether foam is used wet or dry, and the abrasiveness (cutting ability) of the applied machine polish, and no single machine polish can do it all; it usually takes at least two or more to obtain the results required.

The only constant is; Always use the least aggressive product first, evaluate the surface, then only if necessary, `step-up' to a more abrasive products.

The random orbital buffer gets is name from the action of the buffer (or polishing head) This operates by the shaft rotating and spinning the back plate on an orbit radius or an eccentric offset (or throw) of 5/32-inch as opposed to a revolution on a direct-drive system
