Zero confidence in buying machine tools
I'm confident I'm fucked lol. I know nobody and I am incapable of interacting with normal people so forget about getting through word of mouth and buying in person. The assholes who want to sell off their piece of junk are gonna trick me into buying it 100%. So much social mind games going on when it comes to dealing with shopping for heavy equipment, I can't win this. I can't bargain for shit.

Buy some clapped out thing from a local auction site for scrap value. Just make sure it is American.

Learn on it, fix it up a bit, figure out what you actually need, and then get that.

Whats your problem even and also are you stupid? Is that your problem actually?
Most of my machines I ever owned I just bought through classifieds, only very few from a guy I knew. Lathe, planer, mill, pantograph, cutter grinder, ID grinder, OD grinder, shaper, flat grinder, 3d printer and probably a few I am forgetting about rn I bought through classifieds. All second or n-th hand. There's no point buying new as a private person IMO. The machines depreciate in value fast asf and if you're not under economic pressure to churn out product at high rate with as good as zero rejects then what's the point. The CNC shop on the other hand has to invest to stay on top of the game. Amd you can just grab what they don't need anymore for scrap value.
>bargain
When 4 ton machines are 500 bucks? Why 'bargain', are you jewish?

wtf are you talking about, buy a lathe and shut the fuck up. you want to get into machining? cool, now you learn how to fix machines. get it together, stop being a pussy. you have access to all human knowledge online.

Either buy the chinkshit online that needs 0 human interaction, or find a decent old lathe and buy it at list price. Nobody's gonna talk to you at length if you don't try to haggle, and it's not like you're gonna have any educated questions to ask about the thing.

the only way to get more confidence buying machines is to buy a few turds and then figure out why theyre pieces of shit. dump them to somebody else and upgrade. repeat until you have a shop full of good tools
most geezers selling machines are aware of their mortality hence the sale. theyre usually glad that anybody is taking interest in their old junk. think of it as a learning experience. theyll usually info dump on you and often have other shit to throw in that wasnt listed. theres a bunch of geezers that enjoy refurbishing machines and selling them essentially at a giant loss just to have something to do. i know 2 guys that do a couple drill pressed a year each. nice old american iron. they spend $1500 and 6 mos of work then sell them for $1k for a nicely painted and mechanically refreshed tool
start with something easy like an old drill press. find one that hasnt done production like at a gov surplus auction from a school. figure out how to move it by breaking it down into manageable pieces. take it home and clean it up. thats 3/4 of machine tool fun
slowly youll get more comfortable and start buying bigger shit. once old iron sickness strikes theres no cure. only symptom treatment with metallic acquisitions

You know this dude probably has a 2018 Ford Focus with an automatic transmission and lives in an apartment on the 4th floor with a cat. He wouldn't know what to do with 250 pounds of iron let alone a retired three phase machine.

i dont know what to tell you usually i pay what the asking price is. maybe you should research on the lathes that are available to you. like you could look up common problems and try to see if those are on the machine you want to buy

i got an old atlas lathe very recently. my dad bought it from a guy in the 90s and then never used it. getting it out of his basement and into mine was a cluster. there is a gear assembly and a brass nut that I didnt know were badly worn it was $300 to buy those parts.

Adding to the "old shitty machine" club. I bought this south Bend for 600$ in pieces with a bunch of problems, knowing I'm going to abuse it by doing a bunch of stuff that would make purists cry. Took me a few weeks to get it where I wanted but now I'm making parts. I've tried to do similar with shitty broken Chinese junk and in general they don't come back as nice. Once they're broken you're probably never going to get it quite right.

idk about southbend, wrong side of the world but IMO there's just some types that do not understand that industrial hardwre originally meant to be reliable in production is not the same as some chink slop consumer toy. They just cost the same now because one is cheap shit and the other simply isnt productive, or worse, compliant with health and safety anymore.
Got a very small second operation lathe. Looks to be similar in dimension and use case to what you're showing. Weiler 260.
She sure had a rough life but after geometrically overhauling her (the prisms really had about a mm more meat under the headstock compared to the exposed ways) I'd trust her any day over a new chinese thing. And I bet no such chink toy will take cuts as juicy as that thing without shaking. Paid more for the bearings than the entire machine but the rigidity, for the size of her, is out of this world. I'll post a pic of that cutie if I have one on my phone.

>incapable of interacting with normal people
OP, buy the machines I don't need anymore. You won't have to interact with anyone outside of 4chan.
Today I'll offer you a cute Klopp type M3B shaper, approximately 450mm stroke and 500mm table travel, 2.2 kW.
When I got her I tore her apart completely, inspected and cleaned everything, replaced all rolling element bearings, painted some stuff. The design is really nice not that modern boxy shit. I'll have pix if youre interested. Shipping is on you.
I want 1k bux.

The thing about buying old lathes is you need to bring measuring equipment (and know how to use it of course) to check the ways, see if the tailstock and spindle are concentric, etc. if the ways aren’t flat you’d have to have them ground back flat etc, it’s a pain in the ass to restore old machinery and without precise measurement tools you’d have no idea

going by what OP posted I am. assuming it would have to be contracted anyways because OP neither has a large flat grinder nor a planer.
I'm just saying idk why fags wanna grind everything nowadays. PITA to set up. If you want it to come out right you'll have to dress again and skim. No clear indication of geometrically undefined cutting edge being in good nick. The grime and dust is ugly and annoying. The tools expensive and can't really be homemade (at least not by me in my home). And so on.
Planer tools on the other hand can even be cold working steel. As long as the edge looks good it's exactly where you set it. Swivel the head, check against sine bar and off you go. Chips are nice. Noisy is soothing. Motion is hypnotic. Can hop on for a ride on the table if shes large enough and you know what youre doing. Feedback when scraping is super nice from the first pass.
And so on.
There's a reason why they say about shapers and planers what they say.

no you dont. you just learn to work with the machine until you find something better unless its some unicorn tool that you have twisted your mind into coveting
case and point. i bought picel because i was hard up for a lathe to do some paying repair work. convenience was the primary factor. it was at auction 15 miles away and i had a connection to get it loaded/unloaded without paying the riggers. i went and looked at it and it seemed ok for an 80 yr old machine. no gouged ways. all the gears sounded fine. auction day comes and i end up paying way too much ($6k with buyers theft) but i was in a pinch. get it moved and start cutting shit and oh fuck it cuts 1-1/2 thou to the inch taper for 14 inches out from the chuck them cuts straight. the back flat way has a black hole of calcutta worn from lack of lube many moons ago. i twisted the bed with the levelers and got it to 1 thou/in and just marked parts in increments and cut steps. its a pain but works. its not worth the assache to rebuild and will go to a new home or probably the scrap pot when the circumstances are right

really depends om what you want to do and intend to use the machine for
its always nice to have something that is to spec
but I agree it's not always necessary
watchmaking? Anything bent and twisted will do, same if you just need it to prep welds, turn down shit and general fuckery.
Toolmaking? Gages? Not gonna happen you'll be crying youself to sleep.

no disagreement. people love to jerk off about precision and accuracy but the overwhelming majority of shit is +/- 10 thou shit in reality. and 1 offs are made to fit each other anyways. nobody is making 1 micron gage standards at home for any rational purpose. i like to make parts on size as much as anybody but most of the time close enough is just fine
my ole beater sb9 at home has a 12 thou saddleback but will still cut about 5 tenths over a couple inches without any monkey business. its limiting factor is horsepower. the flat belt just doesnt have the balls to cut hard enough chipbreak steel without stalling

i'm guessing he's moving the machine up so he's prying it up standing above it but what happens when it's being unloaded do you really wanna stand under the thing while it's held by a belt not to mention is also probably more difficult to pry it up then and what happens at that weird junction where the incline meets the flat plane

Would you be in a good mood if your job was to literally build rocket ships to fraction of human hair width accuracy for a at rate that is less than what high school kids get at GameStop?

If they feel like being assholes to the office staff telling them that they’re out of low speed steel and only have high speed steel so they can’t get parts done today then let em

>out of low speed steel

are you implying there is a business, in 2025, that makes tools on a job basis and where all tool steel that is not HSS is considered a good enough alternative to any comparable grade?

Well idk about you but my 'home' is sort of integrated with a business which might be why my standards are a bit different. But then again I know guys who do that sort of thing literally at their residential only home. Including gaging tools.
>one offs are fitted differently
I know. Thats why I put watchmaking there as an example. Watchmakers have the worst precision and accuracy of anyone while keeping runnjng theie mouth about alleged precision. There's a reason why they don't use involute gears.
>5 tenths over a couple inches
So you wont be making long fits on that and will need to have to take it on the OD grinder and diameter isn't the only geometric error lathes produce.
But I mean then again you're habitually using calipers to measure when turning. So that perfectly proves the point: Depends on what someone is using their stuff for. I like my clapped out lathe alot for example. Because anything dodgy, heavy interrupted cuts for stuff that will get welded anyways, like farm machine parts, truck parts, dirty stuff, hard material, slag on it... it all goes on there and I clean her when I need to.
But that one is clapped out and wont make anything thats round and without taper.

We aim to center drill both hole locations by the end of the week

We can circle back and connect with you on any challenges we might anticipate with our roughing passes we anticipate by the end of the month.

We also would like to follow-up on our order of size A drills jobber length split point 90 degree tcutting angle make sure you get those! It’s a rush order

Starting off with a crappy tool when you’re a brand new machinist will make you hate the hobby. Sure if you know what you’re doing you can work with a flawed machine, but OP won’t be able to figure it out without a LOT of headache or maybe not even at all

There is difference between crappy and broken
You don't need the compressed air tool holder or the .0000DRO on your machine, you don't need it to be brand new clean and scratchless either
Anon's twisted lathe is just plain broken and he got fucked out at least 4 of those 6k for it, but that doesn't mean all the basic ass 1950s lathe are bad by nature and will make you quit when you start.
A new comer should absolutely start on some old wasn't even state of the art back then 1940s beater, they won't feel bad crashing it, they'll learn the fundamentals and figure out if they do want to splurge 1k on that tool holder

Where would that magic and arbitary cutoff be where you just stop hating all machine work, regardless of what youre doing? Schlesingers acceptance standards? More precise? Or more clapped out?
Idk my man but your statement seems like a comical exercise in generalization on the one hand and on the other hand just stupid in general.
I've said it before further up and will repeat the claim that is founded on nothing but experience and common sense:
The right tool for the job. If you're just making a new pin for your fucking excavator bucket because it wore half way through and then ripped the fuck out you can just pick some random hot rolled structural or mystery steel and do that on any old clapped out lathe your grandpa left you. If you need a sliding fit thats half a meter long it's just not going to happen on any lathe take it over to the grinder.
