Comments:
Another example of the ubiquitous Dunlap 12" rigid arm scroll saw.

I purchased this saw for $7.50 from Tim Resch in Aug07.
Bob Masters Ruckered it from NJ to me at ArnFest07 (6Oct07).

The saw is in excellent condition and I didn't feel that a complete refinish was necessary.
I disassembled everything, drained the oil and cleaned out the crankcase.
Steel parts were buffed with a fine wire wheel.
The table was washed in Zep. The table top was derusted with a maroon Scotchbrite wheel. Next I applied wax, allowing it to dry, then buffed with white Scotchbrite, using a random orbit sander.
The lower blade guide is MIA (attaches to the rear pivot pin in the second photo), but I don't think it will be an issue.
Moving joints were lubed with 3-in-1 20W oil.
The crankcase was filled with Valvoline SAE30 Non-Detergent oil.
Note: the third photo shows the crankcase vent hole in the boss on the side (the saw must remain upright).
A 25tpi x 5" pin blade is installed.

Update-28May2010: traded this saw to a fellow OWWMer for a grinder. He was looking for a compact benchtop scroll saw.
