1930 REO
(photo record for work performed in, Invoice #7

Photos 7-1a thru 7-1f) Photo shows disassembly of rear axle brake dumbs, brake backing plates, and park brake for clean-up and epoxy application. The driveshaft yoke is rusty but cleaned up nicely as shown in following photos. I disassembled the park brake to get epoxy on all of its surfaces. I put the small brake parts to soak in vinegar and will epoxy coat them with other parts on a later date.

Photos 7-2a thru 7-2d) Photos show disassembly of front axle, spindles, and brake backing plates for clean-up and epoxy application. Inside the brake drums, photo shows the beginnings of rust on the braking surface. The rust is not pitted but is only a stain at this point and cleaned up nicely. The epoxy coating on braking surfaces will need to be stripped off before final assembly of automobile but in the meantime, the braking surfaces need the protection of the epoxy to keep them from rusting and becoming pitted. Note: The forth photo below shows some light rust beneath the current primer on the inside face of the brake drum (not the braking surface). I do not know who applied this primer but, because the braking surfaces of the drums will need to be stripped at a later date anyway, and because the primer appears to be holding the rust down well enough for now, I felt it would be overkill to address this issue at this time.

Photos 7-3) Photos show prep of rear shock absorbers in progress. The rust was not pitted but only a surface stain that came off easily with vinegar and a dish scouring pad.

Photos 7-4a thru 7-4d) Photos show further clean-up work on park brake and driveshaft yoke. Note the sharply defined line on the top of the park-brake’s outer surface (bottom photo) The line divides the surface that has been cleaned from the surface that has not been cleaned. The before and after is a big difference.

Photo 7-5a and 7-5b) Photos show clean-up work on front axle.

Photo 7-6a and 7-6b) Photos show brake backing plates cleaned and prepped for epoxy coating. Both photos contain one unfinished backing plate to highlight the difference before-and-after cleaning.

Photo 7-76a and 7-7b) First photo shows parts prepped and ready for epoxy coating. Second photo shows work area.

Photo 7-8a and 7-8b) Photos show rear axle being prepped for epoxy coating. Only the nose and ears need primer. The rest of the axle was urethane coated approx 5 years ago. The nose is bare steel but the ears are coated with a light gray primer that appears to have a slight about of surface rust underneath. I do not know who applied this primer. The bottom photos shows one of the ears before I scrubbed it with vinegar. I did go as far as to strip the old primer off the ears. I did not because the ears will need to be stripped later anyway if we chrome plate the axle as planned and therefore the work would have been overkill. Instead, I scrubbed them and removed the visible rust, then coated them with epoxy.
