Who has machine tools?!?

[netsurferdude2]

I finally got may lathe running over the past month.


2 weeks ago I installed the DRO to match the one I have on my mill.

I did my first threading on a lathe.

(no commenting on my thread profile. The nut fit, thats all that matters)

Made a chuck key for my 5C collet chuck.


Also I nabbed this from work for the price of scrap.
Mostly 0-1 but also D2, S7, 6061 and 12L14 (I think I need to invest in a heat treat oven)

Thanks for the help, found everything I need 😁

THis lathe made it's first chip in the last 3 decade ... Super smooth!


Now I need to get an AXA tool post ...

Check eBay. Lots of people like rebottling smaller quantities of semi-specialty oils for the home-shop guy. Way oils in particular- most are only commercially available in gallons, and to a typical home-shop guy, that gallon will last three lifetimes. Buying an 8 ounce bottle might cost more per-ounce, but lots less than the full gallon plus shipping.

-A felt-lined bearing? No such thing, on a machine tool, that I'm aware of. The felt is likely a "wick" or primitive seal, to keep the oil in on a 'plain' bearing. (IE, a bushing, no rolling elements.)

Looking at the exploded views again, you're right 😋
It has a grouve going around the brass/bronze bushing to keep it nice and oiled ... Found the book is calling for 5W on those bearings.

Now I need to get some 5W and 20W non detergent oil (I got access to about 50gal of 10W so I'm good that way ...)
Any good places to get small quantity of oil?
I don't want to buy another 55gal drum 😅

That's CAT50. CAT5 is ethernet cable.

Do you have any advice for felt lined "bearing"?

My former boss and really good friend had a stroke recently and now can barely use his left arm.
I've been helping him at his machine shop every week with the heavy lifting.
This week was unloading & moving a tool rack and reloading it once we set it up.
Lots of CAT5 tooling, figure you guys would enjoy seeing it...

For those unaware of the size of these, the table underneath is 8'x10'

Thanks for the input, no pressure washing!
I'll clean it with WD-40 and see what I've got.
I'd like to do a "light restore" on it so I can use it sooner rather than later ... Time is scares and the paint is actually in decent shape so I probably won't go too deep into it (yet) (and I've got a jet 6x32 belt sander and a 1954 shop Smith needing a rebuild ...)

Don't pressure wash it unless you're doing a full disassembly. The washer can force water into nooks and crannies where it'll start to rust.

Unless you're doing a paintjob-level restoration, just giving it a wipedown with WD-40 and some paper towels is about all you need. Personally, I love rebuilding and repainting the things, but more often, I'd rather be using it.

Got this old lady ... Now I need to find a spot and bring her home ... 😅

Well got some time to go through the 2 boxes of goodies that came with the lathe ... And it came with just about everything from the 1936 South Bend catalog! So i should be set for a while ...
The only things mission are a 0-1 micrometer (got the 1-2 & 2-3 street)(already got a 0-1 to finish the set) and a center for the head stock if i decide to turn in between centers. The tailstock is mt2 but the head is mt3 or 4 ...

It also came with all the grease and grime that accumulated on it for the last 80+ years 😅
So step 1 is gonna be pressure washer and oiling .. .


I think all I'm gonna do to it is a quick change tool post and maybe dro & tacho?
Any recommendations on quick change size for this lathe? Looking at OXA or AXA ...

Anyone added drop to an older lathe? Any regrets?


PS: after much searching i identified it as a South Bend 415 only made in 1936. It's the model between the classic 405 and the famous "South Bend 9" serie.

I'm thinking of making a table that goes over the shop Smith ... If you can't go out, go up ...

[XEMON]

The guy had no ideas what he had and someone picked it up for me ... Haven't gone through it all yet ... but there is 3 & 4 jaw chuck, a few dogs ... There is an entire storage box (the one underneath) full of stuff ...
It's at my in laws right now (till I find a spot at home 😅)

I also have about 200lb of tooling I saved from the scrap at an old job (half of it new, the rest barely used) , it's been sitting in storage for the last 8-10 years ...
So with all that and what I have at home for my Emco compact 5 I should be set for a while ...

[KMDPB]

thats some nice Iron! Any tooling with it?

[flyweightnate]

Yeah, I absolutely get that. I buy nice drills and taps because I know how to do those ops reliably; my end mills are junk and I know it, at the moment. When it comes time to buy a box of inserts is going to be a tough decision.

I'm kinda 50/50 on what quality of tooling to buy when you're a beginner.

I've only had my mill and lathe for 3 years now, and when I first started out, I bought the cheapest tools I could find. Brazed carbide for the lathe. Cheap HSS end mills from Asia for the mill. And yeah, they didn't do so great. But I also made lots of dumb mistakes while I was learning, and I broke/dulled quite a few tools. I think I ended up buying three sets of brazed carbide tools before I started making my own tools from HSS blanks. But fortunately, those tools were cheap, and buying a replacement set didn't break my budget .

Now that I'm more experienced, I've started investing in better quality tooling, and of course I see the difference. But if I had started with high quality stuff right from the get-go, I don't think I really would have known what "good" machining looks like because I wouldn't have the comparison. Also, while I suppose it's possible that I wouldn't have broken so many tools if those tools cut better, I still would have broken some of those tools. And while I have no problem replacing a $20 set of end mills, I would feel a whole lot worse about replacing the $200 set that I have now.

I guess I'm saying that even if you have the money, maybe it's not a good idea to buy a nice, new Lexus as your very first car. You should probably start off with something used and cheaper to fix. Then when you're confident enough, upgrade to the nicer things.
