Yes. It's a machine used to convert round bar stock to small
cylindrical scrap very efficiently.
I see them do that to wood, as well. Odd choice of hobbies, I must
say.
Is there any way to get an air hose inside to attempt
blowing out the swarf from inside the gearbox? Some of those old
boxes had some extra room in them, while others were completely
stuffed.
The whole works is inside the gearbox, behind a big gear that's less
than an inch from the chuck-side bulkhead. The drain hole goes from
just under the bearing down to below the level of the oil, slanting
from right to left going down. If I could blow it out from the bottom
I'd blow the swarf right into the bearing. That wouldn't harm the
bearing if it's delryn swarf, but it'd eventually get washed right
back into the drain hole.
Arrrgh! Before I get any more old arn I'm going to think about the
ease of (or lack thereof) rebuildability of said arn in the process.
I'm guessing it doesn't have the split case where you can
lift the whole top half out of the way. That would make it too easy.
Correct and yeah.
I physically cringed when I saw that pic. It's total rebuild time,
Don.
Chucks can get really wound up on the spindles, so sometimes it takes
a whole lotta torque to unwind 'em.
I know what you mean. I have a 9" Logan that has a 1-1/2 x 8 threaded
spindle like a South Bend, had a chuck stuck on that one a couple of
times. Engage back gear, stick 2 x 4 thru the chuck jaws ...
I've seen the cover off and a tubafore sticking in the gears, too.
Whatever it takes to multiply torque and solidify the machine prior to
that simple twisting motion. And after all that, you may hear a soft
and simple tink to indicate that it broke loose inside. That's such
a satisfying sound, innit?
There is no chuck mounted. It's a D1-4 camlock spindle, not a threaded
one. Chucks can't get wound on tight.
Have you tried strapping
something firmly to the chuck and whoppin' on that? (I'm sorry if I'm
getting too technical for ya.)
I'm keeping up OK so far. I guess that would be easy enough to do
since the chucks are on the floor, but I'm not sure how that'd
help... G

Jeeze, bigarse beastie, innit?
A 9" it ain't -- but it's every bit as precise as my 9" Logan and a
hell of a lot more rigid. Chatter? Wha's dat? Don' get no chatter
on this machine, uh UH ol' Son. It's not quite as "feely" as a 9"
Logan or SB but I have no problem making little teensy parts on it.
That's very good.
I inheirited it from Mary's dad. Well, actually, from her mom when
her dad died. I still think about old Bernie every time I use that
machine, which was several times a week when it was working right. He
was a good friend and fishin' bud.
Well, g'luck with it.
And make bloody well sure that there isn't a retaining screw in the
very center of the chuck, like a drill chuck. That'd turn ya pink.
DAMHIKT
Left hand screw at that, right? Been there, done that, got the tee
shirt.
Those are always fun, too. But chucks are almost always RHT, lest
they spin off whenever you throw the ON switch. The engineers got
that one right. I had a friend in high school who had a tiny old
British car. (can't think of the make right now) 3 Whitworth lug nuts
held each wheel on, and they were LHT on the left side of the car.
