There's that big vacuumy sound again! Congratulations! The tailstock alone probably, weighs more than my whole mini lathe.

1 to 2 seconds.
The idler starts full rpm almost instantly provided there is no load on startup so I make sure the compressor switch is off.

It is mostly a function of the total mfd of the capacitor bank. You'll probably find it in my thread but iirc, the recommended capacitance is about 60 mfd per horsepower of the idler. However, and again iirc, I decided to try 400 for 7.5hp first and I believe it is just about perfect.

Btw, I waive the "see it running" requirement. You maybe paid for one chuck and got the whole damned thing.

The spindle mount is like the clausing I used to run. It has a nut on the spindle with a taper inside the chuck mount and a driver key. The through hole is 30 MM.

It is 1600 KG on the tag. so yes it's heavy. 3500 pounds or so.

Thanks for the good words all.

It's an "L" series mount. You can determine the size by comparing dimensions...

Wow! That's even better. There is NO substitute for a heavy, rigid machine--makes a world of difference in operation. Parting off can be a real pain on light, spindly machines but on something that heavy and rigid it will be a pleasure.

Damn you got a good deal...

I'd offer you 3 times what you paid for it but I bet you'd be a prick and turn me down

HMMMM............ I find no need to argue with someone I know is right.


Yes L mount it is.

Did some throwing out in the garage and shuffling stuff around getting a spot for it close to incoming power so less wire to run and buy.

I did some more fiddling with it, I find that the threading lead screw and half nuts work properly, found a video on youtube of someones interpretation of cutting threads without a thread dial.

I did find that the feed shaft turns, however the carriage feed and cross feed do not work. when I engage the levers the hand wheels lock in place like they are engaged so their is another opportunity to clear a hurdle, hopefully it is only a shear pin or something on the feed shaft. There may be a key that has sheared off or some other something going on in the apron.

It is sitting on a couple of 4x4s in the interim. If I can sneak a little time in I'll give the electrics a look. I have a birthday party tomorrow afternoon granddaughter is 9 tomorrow.

If anyone has a parts breakdown of something like this machine it would be appreciated or another name brand to look up. Luzohng is one I found and can still purchase from China Not near the deal I got on this one.

There should be mechanical interlocks in the carriage so only one feed can be used at a time

Well I have no been into the lathe so far. However it has moved into its next home here.

My YouTube video of Clapton playing the blues was 51 mins and change. I listened to the last couple of songs in the lawn chair.

Picture of were it started fan on the move and in place.

We will see how it works out there.

7.5 hp motor is waiting for me to pick up. A timer is here. Shopping for capacitors I thought I had a contactor. It may have been junk though. It was laying in a parking lot somewhere.
