Jeff, how much misalignment are we talking here ?

One of the variable Woodfasts was maybe 3-4mm out. The guy couldn't figure out what the hell was going on until we shimmed the tailstock. The turner was working to one of Ken Wraight's templates for a box and couldn't get it centred with tail stock support in the jam chuck. Not good enough IMO. I've had 3 blue Vics hit dead centre all three times. Different QC I guess.

Hi Ironwood
The GPW midi for $475 is our 6 speed model.
It has a 1" Tool post.
The bearings are deep groove ball bearings
It's made in Taiwan, which means that the build quality is exceptionally high.
It has a 7" centre height which is bigger than the Woodfast and the Vicmarc.
Being in the industry for over 30 years Gary has visited factories in Australia, China and USA. We feel most comfortable with our suppliers in Taiwan having a great working relationship. Any problems or spare parts are dealt with ASAP.
We also have 2 VS models in this lathe as well which have been very popular, so popular that we have sold out. We will have more in approx 3 months.Cheers Huon

GPW lathes
Mate, while I agree with the view that Vicmarc lathes are the bees knees, I just couldn't bring myself to spend the money. I even got the OK from Swmbo to buy a Nova !
I now own two GPW lathes and cannot fault them at all. The alignment is perfect straight from the shop and they are more than solid enough for all the turning I do. I turn things from pens to hollow forms ( would turn even more if I wasn't building a kayak). These lathes are both better than I am and the combined cost was less than $1800 new. Price now gone up a bit. These will last longer than I will !!
These are the ones I own -

Well I spoke with Gary Pye on the phone this afternoon about the Midi lathe which he sells.
After talking at length with him about the lathe, it is now also a contender.
One slight hiccup for me is the shaft size on the existing motor is 14mm, my motor shaft is 3/4", not a huge problem, as I have a metal lathe and can bore it out to suit, though sounds like the lowest speed pulley step will be cutting it very fine at the larger bore size.
If I lose that pulley step, no big deal really with the 1hp & VFD I probably would never use it anyway.
The original motor runs at 1400rpm, mine runs at 2800rpm, so I will mainly use the 4th speed (1500rpm) which will give me a top speed of around 3000rpm if I run my motor at a bit over 100%, I can set to run higher than that and probably will set it to get 3500rpm top speed on that pulley step.Brad.

Jim wouldn't it be a disaster if, all these years, you had been using a lathe that didn't line up?
Imagine how much better your work would have been if you had checked this before you started
I am going to rush out and check my lathes first thing in the morning.
I probably won't sleep tonight worrying about this.
Cheers

On this point, whether or not the centres line up perfectly is partly dependent on whether or not there is any side play at all in the tailstock on the bed.
In my case, the centres line up perfectly in the vertical plane, but due to slight side-to-side play in the tailstock on the bed, it can be as much as about 1-1.5mm out in the horizontal plane.
It's perfect horizontally only if I hold the tailstock 'clockwise' as far as it goes before/during clamping.Last edited by Hermit; 12th May 2014 at 07:23 PM. Reason: 'Tailstock' not 'banjo'

G'day Hermit
Small horizontal adjustments to the tailstock can be made using the following method.
Using a centre punch and a hammer the cast iron can be swollen a small amount.
You know which way you need to move the alignment.
Lots of centre pops in to the cast iron will gradually expand the metal.
This is the method used to tighten tailstocks that have worn after years of use.
Do a bit and check, do a bit more and check again.
Caution don't punch to close to the edge or you will break out a small piece.
Steady steady is the go.
Hope this helps
Cheers

Thank you for that, Tim. Guess what I'll be doing in the morning?
This is yet another 'why didn't I think of that' moment.
I 'adjusted' the aluminium 'T' bar in my bandsaw mitre guide using this method, but didn't think of it for eliminating the play in my tailstock.... Steve

Just because the two centres happen to meet doesn't mean the tailstock spindle and the headstock spindle are on the same plane.

- doesn't mean the tailstock spindle and the headstock spindle are in the same planes or collinear.
Having the centres at the same height and parallel to the top of the tool rest is a big start though and for a piece driven purely between centres that is all you need.
We introduce complexity into fine spindle work when we hold the headstock end rigidly in pin jaws or a collett chuck or std chuck jaws or even with a MT2 cut into the workpiece & jambed into the headstock and with tailstock support. Finer & more delicate spindles require higher alignment precision or no tailstock support. Same goes for any fixed or string steadies we introduce into the system. It certainly helps if the spindle turning axis, centres and steadies are all collinear. A lack of collinearity is the most likely source of whip – either caused by missalignment of the headstock / tailstock / steadies or compression of the work piece bowing its axis.
Collinearity can also be an issue when we reverse chuck bowls etc using a reversing mandrel. Anyway this is a side issue to the main thread.

Well, after a lot of thinking, and "to and fro"ing, I have decided I will be going with the GPW Midi.
This purchase, as well as all my other hobby related purchases are funded by what I can make out of them, penturning is the major source of funds coming into my hobby account.
The Vicmarc was stretching the account a bit too far.
The decision to go with the GPW was made easier, when I decided that wouldnt restrict myself to just one lathe. I will sell my Record at some stage and get a bigger lathe, possibly a VL300. But that will be a way down the road when my circumstances have changed and I have time to turn more than just a pen now and then. ( I work 7 days a week with my business )
I am confident I will be happy with the GPW, and it will be a huge improvement over what I have been using once I get it set up how I want it.
I will start a new thread when I start the setup of my new lathe, with plenty of photos and a bit of a review.
Thanks to everyone who contributed to this thread, your input is muchly appreciated.Brad.
