Logan 820 year confirmation?

[Mill Lee farm]

So an 820 just followed me home despite the fact that I'm in process of buying a clausing lathe. It's a disease.

Anyway, I'm excited to get working on it. First thing is to determine it's age.
Serial numer is 42926
Appears to be 1946? 1947?
That's older than I thought. Is that right?

1947. If you look at Logan's website at lathe.com you can look them up in the FAQ. http://www.lathe.com/ser-no.htm
Let's see some more pics!

Yes, OK. Been a little busy. I'll get some pix up asap

Here are a few from before unloading

Looks great! Nice to get Aloris and Rohm parts in the bargain. Hopefully with some
cleaning and rust removal you'll be in business. When you get it running, be sure to
evaluate the condition of the spindle bearings. The chuck-side one is proprietary (ie. expensive)
but available through Logan. The other can be obtained from the usual suppliers.
Logan offers a surprising number of wear parts for these things, though prices are high.
It's good to know they're available however.

Yes. Been reading through a couple of the rebuild threads etc. this one needs some work. Probably should have a good rebuild. That might be in store… we’ll see

Here’s the BIG problem….. bull gear crunched. Mating gear below looks good and I checked all the other gears and QCGB. All look ok.

Some folks repair those by brazing the teeth up and machining, but if you can't do that, eBay would be the place
to look. Pulling the spindle is a good opportunity to change the belt or bearings if needed anyway...

What do I need to bronze braze it? I only have a Mapp gas torch. Don’t think that will do it will it?
Might try find someone local.
As for milling I would have to make a VERY amateur attempt with my 7” Atlas shaper and 5C spin indexer???
IDK… I’d rather just put a good used one on, but they appear to be $100-$200 on ebay?

Think I know how the bull gear got all busted up… the Rohm chuck is totally stuck on the spindle. Assume someone was trying to get the chuck off and destroyed the bull gear?

As for the rest of the lathe… HOLY CAST IRON BATMAN!!! This thing is absolutely CAKED with cast iron grit. Its everywhere and does NOT like to clean up!
Ughhh….
Not too many chips… think it was mostly used to turn cast stuff….

I’ll get some better pictures to get some opinions of ways etc… don’t look great.

Here's a vid which will give you an idea about what's involved in repairing the gear:

Probably would be a good idea to dismantle the machine and get all that grit out. A quick and dirty
way to evaluate bed wear is to measure the the thickness of the flat portion of the way on the back side of the lathe
with a micrometer. Start at the tailstock end and measure every few inches till you get to the head stock. It's
not a perfect measurement, but it's easy to do and should give you an idea of where you stand.
