Cool tool

[Observer]

Hey guys - I've recently come across this nifty device.

Its a drill reverser from around 1956 maybe later, before two way drills. It lets you control direction depending on which half you hold (planetary gears allowed to spin or not)

It slows the spin down enough to be used as a tapping head for a drill press too which is my plan:

It's disassembled to clean and examine it for reverse engineering purposes lol- problem is I cant get to the bottom section.

Any idea how to get that gear ring out>?

It appears to be pressed in, the metal plate under it spins freely yet is solid to push on.. or maybe pull through the holes but it might bend it..

Any idea how to get that gear ring out>?

Yes, but not without destroying the case. Sorry I couldn't resist.

The speed reduction was probably even more help than the reversing part. I can't think of any electric drill from the 1950's, that I have seen, that was variable speed.

is it a press fit? if so, heat the outer shell quickly, but not too hot. the ring gear should fall out if heat is applied quickly and evenly

My grandfather used to have a dozen of these in his vast tool collection. He was a boilermaker by trade. Wish I would have taken a few before most of his tools were stolen.

Off topic but it's fun to read those "career training" ads in the old magazines.

Don't break it while cleaning/studying it!

I will be extra careful- good point about the expanding, but Id rather use cooling on the inner one as I don't want to warp it with heat if possible.. and the grip has plastic coating of some kind.

So many cool gadgets in those ads, makes you wonder how we went from all that to "sham-wow" on tv. A cloth.

I should mention that I bought several beat up ones.. this is the worst one but still precious. Not that it would be hard to make a modern day one- its a fairly straightforward thing.

And I also got this:

New in box, going to be safe with me for a long time. Promise!

Found one more on ebay for you: http://www.ebay.ca/itm/Vintage-Vers...ltDomain_0&hash=item257547a44b#ht_2891wt_1027

If anyone wants to mess with one // Carefully that is.

Thx!

Took it to a press today and used a bearing splitter to hold it while driving it through in the engaged position.. popped out no problem/

Looks like it engages the disk for one direction and the threads in the unit for the other direction- kewl.

Looking at the one on eBay it says on the package has Yankee style bit holder. Now I need to know the difference between Yankee style bit holder and Southern style bit holder?

Anyhow that is a cool device. Might have to look into getting one.

I'm sure it was widely known as it is everywhere in the vintage tools area.

"Yankee screwdriver" was a popular tool apparently- all it means is the drillbits have a notched end that drives them and a notch in the shaft for a ball bearing to hold it in place.

The shafts are round, not hex like almost all bits today- easier to manufacture I guess..

Since i'm not against using a modern drill to drive screws with I figure I can rig something up for tapping holes with this thing.

The end of the shaft has a thread on it under the black cap for a chuck attachment for drilling purposes- one I got does not have this but instead has a hex bit shaft so look for that cap on the end if that's what you need.

Found another with USA only shipping and a chuck-

You can have it if you scan the manual once it arrives and post it for us lol!

I assume the boxed one has a manual but it's never leaving that box.
