A Taig lathe is a tiny machine, turning on 3" diameter pipe is way out of it's leaque.
To be able to take any meaningful cuts on 3" stock you really should be using a 8" or 9" lathe at a minimum.

lol, been there..
Good to hear your health is better.

Whoaa...Were you on some good strong narcotics when you wrote that?:D

The 10ee was and still is one of the finest manual tool room lathes ever made. The 10ee had a standard spindle run out of 40...

Wow, I have not visited this forum in a long time. Cool to see my dampers had a lot of interest.
I did a lot of testing early on and there was no doubt that any viscous fluid fill in the cylinders...

Sorry I don't have anymore pics.
Right now the machine is disassembled. I am going to make several improvements. It may be a while though as I am smack dab in the middle of my turbocharged 1978...

I have tried many of the popular cad and cam software from the hobby level to professional level.
At the lower price range I found Sheetcam a really nice and easy to use 2.5 D program with basic cut...

Like Bob said, "They're so tiny!"

You would like to turn 2.2" wheels for RC? I would not consider that little metal and plastic cooltool.
Seriously consider a Seig 7x lathe. It's a monster...

I have a 1960's South Bend 9" model A. Has the QCGB and power feeds on both Z and cross slide. This lathe while nothing like a monarch or Hardinge is way superior in quality than a chicom 9x,10x or...

I think most of us are indeed talking about hydrodynamic plain bearings. Oillite bronze bearings are usually used as a bushing and have no place in a machine spindles headstock. The shell of a plain...

Jason, I still am using the factory ball thrust bearing. Here is a link with further details- http://www.lathes.co.uk/southbend9-inch/page3.html
There is a fiber thrust bearing on the opposing side....

The plain bearing is a remarkably simple and extremely accurate way to go. I machined my own bronze shells for my SB9A. The original cast iron bearing surfaces were trashed when I took possession of...

That would be "Steve" :wave:

That was my early setup and one I probably should have stayed with.

You are welcome Kalvin. Post some pics when you get it all setup!

Steve

Thanks everybody!
Hi Ian, this machine was fun to build. It is quite capable. The portable milling/drilling head works really well with it to.
The 3 speed planetary transmission can provide...

hmmm.. I could use a few extra bucks Rube :)

I am thinking about building a 1/5 scale RC nitro drag bike from scratch as my next project :devious:

Steve

Thanks Joe.
The lathe has now changed hands and belongs to my good friend Rube.
He will be making some improvements to it so it will be even better.

Steve

I think you are confusing the leadscrew pitch accuracy specs for backlash specs. The purpose of 2 nuts is to minimize backlash and has nothing to do with the leadscrew pitch accuracy.
One nut must...

2 more pics of the milling head with a better angle as it was pointed out in another forum that it looked like the motor would interfere with other parts of the machine. No, there is no such issue....

Also, tried out a simple line boring op. The machine makes it so easy!
Here is a boring bar reducer sleeve. It's made of delrin.
And a pic of a simple line boring setup on some pipe....

I just finished this project. It is of course a small drilling and milling head with a rack and pinion quill. The motor is from a mini lathe.
The housing was taken from an old cheap import drill...

Thanks guys,

I just used that piece of accordion tube for the cross feed screw as a temporary protection measure. It will be replaced with something more suitable and not so f-ugly.:D

The...

She is just about finished. It was dismantled, cleaned, painted and the spindle and axis's very carefully aligned....

Those spindle speeders are pricey. Even used ones are and it's hard to find a R8 tapered speeder.
An easy quick and dirty way to get around 5500rpm or so is just swap the motor and driven pulleys....

some updates,
Better column mount with secondary brace greatly reduces spindle deflection.
I finished building the spindle indexing system and tested it out.
It works fantastic. As for now I have...

Bob,
Good points.
But I'm just a hobbiest so everything does not have to be 100% automated for me. So the plan is I will just program in pauses or stops when switching between lathe and index...

Bob,
I'm using the standard x2 mini mill column assembly for the main spindle head.
These do suffer from flex but hold their position quite well. I had a cnc'd x2 some years ago. I'm already...

Some more progress made- It now has 3 working axis. cncd long and short axis and manual z-spindle height axis.
6.5" on the cross feed running at 200IPM,. So I'll be able to use it as a short gang...

dfro,
The tailstock uses a pillar underneath with a stud to attach to any of the central threaded holes in the bed. Very rigid setup but slow to change positions. I seldom ever use the tailstock....

It's looking good!
I would not worry about the tapered rollers. The deep grooves are plenty stout in these head stocks. No way your machine will notice the difference.
I was taking a pretty good...
