Almost bought the exact one at Harbor Freight last week with a coupon.

A fantastic CNC marvel without doubt, but I was using bigger manual lathes over 45 years ago until they de- industrialised the UK.

Is it a big lathe, Yes. Largest? No way. Working in a factory years back, the lathe at the next work station had a 144" (12 foot) swing and a 50 foot attached bed plus a long, unattached sub bed. Across the aisle was a 'little' 84" swing, 25 foot long bed. There were larger in a different department making steam turbine rotors

In the Number 2 Machine Shop at Bethlehem Steel at Sparrows Point, MD was a lathe 125-feet between centers. Finish cuts needed to be made at specific tidal times to avoid distorting the workpiece.

I remember many years ago watching something on TV showing a huge nuclear reactor chamber (or something like that) being turned on a gigantic lathe. The original casting was 15-20 FEET in diameter, made this look like a watchmakers

[barrysmith]

we had a Craven at folkes forge in kidderminster that was from chuck to tail stock 33 metres long. a swing of 96". it had 7 steady's and me "shoveling the swarf" great days of engineering. i weep when i see these great machines.

[drevil]

"Mine is bigger than yours" is definitely applicable here

[jameslee]

I did work in Todd Shipyard, in Seattle, WA. working on a very long Lathe was finishing turning the ship's rail shift, I love being a machinist.

Looking at the thumbnail, it looked more like someone was building a full-scale model of the Wave Motion Engine <g>.

[walterkucharski]

When I was a kid I worked in a shipyard and the lathe I used was much bigger. I had a seat on the carriage and went for a ride that often took a whole shift for 1 cut.

[t.texastimmy]

It might be the longest CURRENTLY operational Lathe, but there were many larger ones in the recent past.

[gudnite]

I worked in NDSM in Amsterdam where I was told that the largest lathe that they owned was reputed to be the largest in the world and the first time I saw it there were four men standing on the toolpost with room for more. I honestly could not believe it was a lathe at first until I witnessed a large marine crankshaft being turned. That was back in 1965 and sadly NDSM closed about twenty years or so after. The scale of the machinery in the large machine shop was like a giant fairy tale and I am so glad to have worked for them.

I worked on a 24" hollow spindle. The steady rest was out in the steelyard on a chain trolley. Manual API thread repair of tool-steel subs, casings, and drill rod. Had to stab the little door, and both sets of jaws. When I turned the tool steel I had to specially grind my tool into what was called a spoon. 20 rpm, feed-rate, min .060", 3/8 depth. Engaged cross feed and lateral feed simultaneously to hog off the end. The shaving came off glowing, then turned a nice blue, razor sharp. It would snake around my lathe and I kept an eye on it (among other things), ready to redirect if it with my broom handle if it got hung up.

How big do you want your lathe?
'The tool carrousel has to be an actual carrousel.'

[igokarts]

I can still hear MR1 Morenz "feeds and speeds" but it's in that slowed down deep voice like when you play a 45 on 33

[mackk]

thats the 42nd smallest lathe I've ever seen

[donlunn]

In Newcastle when we had a Shipbuilding industry, there was a lathe for turning ships propeller shafts. It had operators on both ends, who sat on the carriages and were in communication with each other. “ That was a lathe”

[JohnnyUmphress]

I can't even imagine the foundry that produced the enormous blank for that job.

[schneisim]

Impressive setup. But there are larger ones still opreational. 30m length for turning reactors are still in use mid of germany.

When you gotta get the special catalogue to order inserts you know that it's good.
