Nice  :beer:

I know you said you were looking for a bigger lathe, how much bigger than the boxford is this in real terms?

You gonna do some videos of its installation John?

Would make some interesting viewing in my opinion.
Tools: Boxford CSB lathe, Chester 20v mill, Portamig 185. Lots of ideas, No motivation.

Nice one John - a good make and model I think  :thumbup:

What do you know of it's background - education or industry ?

(Education = little wear but possibly carriage /chuck crashes, industry = potentially much wear but probably less abuse)

Nice pressy you have there john

All you have to do is make room for it , is the sparky bits compatible or are you going the VFD route

Have fun but do look after Debs just keep ticking off the chemo sessions soon it will be half way then the numbers look a lot better that's the way we did it

I would say basically unused no crash damage & no wear
Very light surface rust & grease

It has a fair bit more capacity than the Boxford (diameter wise) about the same distance between centres
No drive belt to slip
Be plenty of vids to come

If you find that it is too big for your space I am sure that I could fit it in here.

Nice one John, you'll not regret buying that. My L6 came out of a training college similarly well equipped with faceplates, Pratt 3 and 4 jaw chucks,multisize collets etc.

I might one day consider adding a longer bed lathe to my collection,like a DS&G, but I wouldn't part with the Harrison....OZ.

Fletch,I forgot that you also have an L6.
 Which phase converter package do you use to run the original 3 hp motor?
 I've still got the original 3 phase motor for mine in storage,but currently have a 2 horse single phase fitted.....OZ.

Hi John, Good news on the lathe and goodies with it.
The only thing in history that even comes close to when the cabinet door became unseized and swang open to reveal a full set of tooling , was Howard Carter opening Tutankharmun's tomb  :drool: :drool: but far as I know he did not find a Pratt 4 jaw so you still edge it by a mile  :thumbup:

  Welcolme to the Worshipful Guild of Harrison lathe owners  :clap:

Just watched the nightcap, much better format with it being one part.

Looks like a nice upgrade from the boxford.

Hi John,
Hope all is going well for Debs and yourself.

Surprised no-one has aked "What are you doing withe the Boxford"?

I know you are super productive what with work/the workshop/the video productions but even you couldn't run two lathers at once!!

Plus it would take up all the walking space in the shop!

I use one of these but keep looking on ebay as you will find one cheaper I paid 160 off ebay new I will post some pictures when on a proper computer http://www.ebay.co.uk/itm/3hp-2200W-IMO-Jaguar-CUB-Inverter-Single-to-Three-Phase-Digital-Converter-VSD-/161588374389?pt=LH_DefaultDomain_3&hash=item259f6aeb75

Cheers for the info mfletch,very much appreciated. That seems a really good quality unit and the manufacturers  5 year warranty is very reassuring as well.

I've been considering reinstalling the original 3 phase motor and a speed controlled inverter for a while now.
I look forward to seeing what setup John chooses to install on his new140....OZ.

Oz, the vsd that Fletch linked is for a 240v 3phase motor.....Your orig motor may not be suitable if it's the original .....check the name plate to see if its dual voltage.....star 415v or delta 240v.....

Yes the motor on my L6 is a dual voltage so it can be changed between star and delta 240v or 415v

John,cheers for the reminder about star and delta,I was planning on having a look at the motor before making any purchase of a VSD.

Looking at the motor options for the L6 in the owners handbook there are various specs of motors depending on the spindle speed ranges,which differed on certain models.

The optional motor specs given for 3 phase 50 hz  are:
(single speed 1500rpm motors)
1.5 hp 34-750 rpm spindle speed
2 hp 45-1000 rpm     "           "

(Dual speed 1500/3000 rpm motor)
3.5 hp 34-1500 rpm spindle speed
3.5 hp 45-200   rpm     "         "

The spindle speeds chart on my lathe shows 45-1000rpm so it follows that the original motor is 2 hp.

mfletch just for interest,what spindle speed ranges does your L6 have,and is it a MK 1 version?......OZ.
