I have a three speed tranny (tower shifter) of unknown make  but a smaller unit that has been sitting a long time. I would like to get it freed up and use it for speed selection on my drill press however the inside is rusted up big time.  Is there any hope of getting it useable with Evaporust or similar product? If so I plan on useing new bearings in it or do you guys think it's just a wast of time and I shoul throw it back in the junk pile.   Thanks  Mark

I'd tear it down to see the extent of it then at least flush it with kerosene and either replace em all now or as they go out depending on what they look like but I would try saving it if possible and within reason. Unless you're using your drill press for dental fillings I wouldn't think it catastrophic for it to be down a few days at a time.

I would take it apart if possible, then put the gears / shafts in an electrolysis drum for a couple days and eat off the rust...... wire brush them when done... should be OK with new bearings.... your not building a race car.

realize that most manuals have ratios of approx. 3:1 , 2:1 , and 1:1 ....... is slowing it down 1/3 speed adequate for the usage ?

hmm why not grab an old lawn tractor tranny ?
Peerless made them 6 or 7 speed gear trannies  AND reverse !
They are dang near bullet proof..

might be  viable option ?

hate to think of the time needed to rebuild a car tranny...

Jaybmiller you gave me a good idea there, I have a couple of junked out lawn tractors one with hydrostat.   The drill press is a 24" Cincinnati with six different feed rates and a three inch drill capacity. It's a great old machine but was converted from flat belt to V belt and is set up for just one speed which is slow. I would like to be able to simply change speeds to somewhat faster without a lot of work and think a transmission of some type would work. Now I think I will drag one of those lawn tractor trannys over to the machine and see if it's doable, Thanks guys!!
