Comments:

This machine was acquired at an estate auction in June 2006. To the best of my knowledge and others I have contacted from the group, the planer is a 1955 or 1956 model. The serial number is odd because of its alpha-numeric digits: G-6625.

The restoration color was found in places that the previous owner could not or would not touch with his brush or rattle can. For example, behind the serial number tag, height adjustment tag, clutch tag, and under the motor plate, was the bluish/gray (grayish/blue) you see in the attached photos. I had my local auto parts store match the color to an automotive 2-part enamel.

Most parts of the planer were chemically stripped or wire brushed. Some parts were cleaned in the spooge tank and a few of the rougher castings were bead blasted. Automotive primer and the 2–part enamel were applied to all painted surfaces. The moving parts such as gears, pulleys, and infeed/outfeed housings were wire brushed and protected with an enamel clear coat. All threaded hardware received the clear coat treatment.

The Valley Industries 2 HP RI motor was checked at a local motor shop, with brushes and bearings the only faults corrected. The electricals were checked and replaced as necessary. The motor contactor was in good shape, but the access cover was missing, so I purchased an 8X8 NEMA box and moved the contactor to the new box.

The planer mechanicals were in good shape. All bushings showed little wear and the infeed/outfeed rollers and table rollers had negligible run out. The cutterhead bearings were replaced. The planer base was reinforced by welding angle iron under the planer body mounting holes. Another angle iron brace was welded under the motor mount plate and a motor adjusting stud was fabricated for belt tensioning to prevent the weight of a 100-pound motor exerting excessive pressure on the cutterhead bearings.

Prior to reassembly, I fabricated a mobile base for ease of movement in my 600 sq ft shop. I created a cardboard mock up of a dust hood and a local sheet metal shop handled the fabrication. The hood was powder coated a light gray/grey. The hood pivots on the chip breaker studs and is attached by one screw to the top of the chip breaker. The 4 pound weight of the dust hood coupled with the weight of the flexible hose had to be overcome or the chip breaker would pivot upward during operation. My solution was to install studs in the top of the main casting and install 2 springs from the studs to the dust hood to counter balance the weight of the dust collection assembly.

Restored: 2006.
