When picked up, this Dunlap scroll saw was rusted, dirty, and the wiring to the motor was completely rotted and unusable. My intent with old arn is to simply clean it up and get it working, so that's what I did to this saw. I pulled the crankcase apart, cleaned out the old oil and a whole lot of old sawdust and put in new oil. The components inside looked virtually new so this part was easy. I used WD-40 and Scotch Brite pads to get the rust off the table, however, even though some stains remain, that does not impact the saw's functionality as there's no pitting. I rewired the motor, which incidentally is a split phase GE only rated at 1/20 HP, but surprisingly it does a good job of running the saw. Part of the reason I'm posting this scroll saw is this unique configuration of the motor, bolted directly to the chassis right behind the table, that so far has not showed up on this site. The motor is small enough as to not interfere with cutting, since it sits below the table's level. The switch is new and I mounted it on a homemade bracket. I also made the table insert as the original was missing. The pump has what I assume is a non-OEM top cap that was added at some point in its life, and it sports a copper tube for blowing air on the upcycle, even though the original small copper tube is still mounted at the bottom. The pump has the original rubber washer that needs replacing but I have not figured out where to obtain a replacement. If anyone has any ideas please jump in. The scroll saw in no way matches the level of restoration some of you have accomplished, but it runs very nicely and cuts very well so I will keep it in addition to its younger 16" DMD brother sitting along side. Another modification I added to this saw is the home made bearing based blade guide since the original was missing. I also think that the hold down foot (crow's foot) is not original but it works.
