Rescued this Rodac 3/8 drill -
goodfellow:
It was languishing on ebay for quite some time, so I made a lowball bid and got it for less than $10 incl. shipping. Unlike many of the early RODAC models, these were not serious industrial air tools, but rather an imported line from Taiwan that RODAC rebranded to compete with the cheaper DIYer tool market. T
The chuck is OK but not great, but the real problem is that the vanes in the air motor were sticking. I heated up some Marvel Mystery Oil and poured it in the tool about a 1/4 ounce at a time. After the third pour, it sprung to life and continued to spin freely without hesitation -- a cheap fix.
It's a good enough drill for quick sheetmetal and light duty jobs -- I've always liked RODAC and keep an eye out for the stragglers on ebay.

Nice save, I've got a little 3/8 bluepoint ratchet that need a control valve. Any idea on a parts source?
jabberwoki:
I like Rodac too , I have a 3/4 impact gun of theirs. It`s quite a beasty.
oldnslo:
I have the red version of the disk sander/grinder. Seems my ebay search just brings up the silver versions for the air drill. My grinder just plows along decade after decade with no arguments. Its a workhorse.

GF, I like the idea of heating up the MMO before application.
I don't know if it's still in the formula, but the classic MMO had tricrestyl phosphate in the mix. Itself an extreme pressure lubricant, the presence of the phosphorus helped in reducing friction, as the ion would bond to steel surfaces. I have read that MMO continued to provide lower friction even when dry - the residue left over had lubricating qualities. Most probably due to the TCP.
So heating it and letting it get into all the gaps and crevices of the device will have lasting effects.
