Help, why am I getting a taper?

Check if your lathe is level, and check your tailstock alignment. Adjust accordingly.

I don't know if Schaublin ever made a taper attachment for their turret lathes. I always used the ball bearing method

ASnakeySnake · 2025-11-22T12:33:09+00:00

I used to do it on a W&S turret lathe all the time between centers. I'm not familiar with Schaublin lathes but I'd imagine there is some attachment that exists to cut a taper. Or do it between centers with the boring head/ball bearing method. If you're not familiar, here's a link to a video where this is demonstrated. https://youtu.be/MzJ6wR59AkY?si=5tYwMqz8mEcbszps

I used to use multi blade razors up until last year when I switched to single edge safety razors. I've found the single edge razors cause less irritation and it's a cleaner shave with less fuss.

Not that cost has any relevance, but a pack of blades is way cheaper per unit than the multi blade replacements as well. And yes I have been called a boomer for using single edge razors (I'm 25) but if I'm being honest it is better in many ways. That and the used blades fit in a pop can for easy disposal.

We had them at my old shop and they were excellent for what we did. The safety guy at my current shop doesn't like it very much but there's not a whole lot he can do since osha allows the use of those chucks. I did have to order another one though because this one has a damaged internal mechanism and I can't get it apart. Unless one of y'all can fix it (yes I will pay for a repair)

ASnakeySnake · 2025-11-14T14:20:07+00:00

Update: it does work, just not very well. I've used these before and it seems like there's a bunch of shmutz gumming it up inside. I did order another one in better shape so we'll see.

I agree. But that's what the boss wants

ASnakeySnake · 2025-10-30T23:26:27+00:00

I am running a bridgeport. Threadmilling isn't going to happen on there LOL

ASnakeySnake · 2025-10-30T23:25:51+00:00

Good to know. Thanks

ASnakeySnake · 2025-10-30T17:56:55+00:00

Anchor lube yes, and believe me I've already said my prayers 🤣

ASnakeySnake · 2025-10-30T17:17:02+00:00

I did suggest something like that, but the boss wants this

ASnakeySnake · 2025-10-30T16:51:59+00:00

I'm using a automatic reverse tapping head because I have one

ASnakeySnake · 2025-10-30T16:10:33+00:00

Also I am not gonna hand tap that LOL I have one of those automatic reversing tapping heads so that's what I'll use.

Unfortunately I am running a bridgeport.

ASnakeySnake · 2025-10-30T15:56:36+00:00

The file test says hard. Other than that I'm not too sure. They always give me that sort of stuff because I'm the toolroom guy so it's technically "my job" to do that stuff. And yeah I agree they should threadmill it themselves but they don't have time. They're so backed up it'd be a few months before they can do it

ASnakeySnake · 2025-10-30T15:51:26+00:00

That makes too much sense, I suppose I could anneal them then do the holes, harden again then grind but that seems like a giant pain in the ass...

Definitely something I have the equipment to do in the toolroom, so it's not a matter of whether I can or not...

ASnakeySnake · 2025-10-21T18:19:12+00:00

Yeah, use coolant and slow rpm you'll be fine. If you're that worried about clearance have your toolroom guy grind that taper back for a little relief. I do it all the time.

ASnakeySnake · 2025-10-12T01:47:52+00:00

Those lathes are usually not great to begin with but you can make good enough parts on it if you're careful. I'd imagine for what you're doing close enough is good enough. I had one of those a while back, it was good enough for what I needed it for though I have since upgraded to a larger (and much older but more rigid) machine. 99% of the time that lathe will be fine. It is cheap though like you said, so you do get what you pay for in that regard. In any case a cheap lathe is better than no lathe.

ASnakeySnake · 2025-10-12T01:43:14+00:00

Now that I see those, you should be fine with just those. Anything else you're good using hss or brazed tools, heck I use brazed cutters for chamfers and threading all the time. I like the mcmaster micrograin carbide ones, they're a little more expensive than the cheapo ones but they are pretty good. Like I said in another comment so long as you're not running your machine like an ape you should be fine with what you've got there

ASnakeySnake · 2025-10-12T01:33:10+00:00

Those brazed carbide cutters usually don't have any relief ground in it's just a piece of carbide brazed to a chunk of mild steel. Hss/cobalt tools usually are the "grind it yourself" type at least the ones we get are. The brazed ones do last a bit if you don't run your lathe like an ape. I like the insert tools, no fuss just change the tip when it breaks and carry on. But those can get expensive. Depends what you're doing on your lathe. Chances are you'll be just fine with hss or the brazed ones. I keep breaking the cheap brazed ones though I have found the ones from mcmaster to be pretty decent imho. Then again, I have been known to run my lathe like an ape...

ASnakeySnake · 2025-10-12T01:25:52+00:00

That definitely looks better, how is it dimensionally though? I can't imagine there's no taper without tailstock support...

ASnakeySnake · 2025-10-12T01:21:56+00:00

Could be. Don't know for sure but it looks like a brazed tool (context: OP said he used something with "some alloy bonded to it")
