It has taken me months of looking and comparing lathes to get to the point where I ordered this lathe.
I looked at the Quantum lathes and on paper they look great, but when I went and spoke to the UK importer and had a look at a lathe they were no different to any of the other Chinese imports. The supposed “German” quality checking and engineering really was not in evidence. The warning I got from the Quantum importer was that the variable speed units had a habit of failing. This comment made me wary of the other variable speed lathes which may be unfair (would love to know your experience).
With the chuck and steadies removed it was just about possible to lift the lathe between two of us. Although I do think we will both know we lifted it for the next couple of days!!.

Having used aluminium tool packing for some time I would not recommend it as it has a tendency to pick up any pieces of metal left behind and they get embedded into the aluminium. The result is they do not always sit flat. A better way is to use brass shims or an old set of feeler gauges.
This is of course helped by the 12mm tools that just do not budge.
I bought a left-hand and a right-hand TCT cutting tool from Glanze. These work great as the 12mm tool is so stiff and so very precise cuts can be made.
This is one of the more tacky pieces of the lathe and is just not to the same quality as the rest of the construction.
Also the safety switch consists of a steel pawl fixed to the cover and this locates into the other side of the switch that is fixed to the headstock. The alignment of this is tricky to get right.
One thing that is lacking with this lathe is the lowest speed of 100rpm. A toothed belt drive is used to get the reduction to a 3 stage v-belt pulley and the toothed drive is very quiet.
Will have to see if somebody out there has designed a further reduction drive – my other thought was to fit a 3 phase motor and then an inverter speed control – thoughts?
As yet this has been running fine, but have thought that I ought to buy a spare belt…
The motor drives a toothed belt reduction drive for the three lowest speeds in the range with a V-belt pulley with 3 steps that then drives the spindle.
The motor also drives a V pulley with three steps that is used for the three highest spindle speeds.
Changing speed is quite a simple task of slackening the tensioning roller, moving the belt and then re-tightening the tensioner pulley.
You don′t need to go mad and tighten the bet too far.
The 1/4″ steel tools tend to be much shorter and so not possible to catch them under the wider spaced bolts, but the first two bolts give an adequate clamping force.
I have been machining a cylinder for a new engine and so using a parting tool to cut the grooves for the cooling fins.
After lots of broken tools and some very poorly formed fins I realised that the saddle was moving under the load.
As you can see there is a large caphead that you tighten to achieve this.
I tried moving the bed with this tightened you can still move the bed slightly – you will need to have a play and get used to how tight it needs to be to stop the bed moving.
Also, clearance on the cross-slide adjustment bolts is not great with an allen key left in this bolt – also be careful to release before you apply the auto feed.
Price: £975 from warco.co.uk as of May 2012
Ordering process and delivery was first class, all the parts were there and in very good condition.
- 4 months old: a cracking piece of equipment that I would highly recommend. I would like a milling machine of the same quality if possible – with the belt drive…..
- 3 years and 8 months old: this is the workhorse for all of the metal turning that I do. I have machined wheel hubs for a rally car, cylinder barrell for an air-cooled IC engine with some difficult deep fins and have machined some finer detailed parts at 1000rpm. I have been around and tightened up saddles and taken some backlash out of handles, as expected really. I have thought about fitting a 3 phase motor and inverter, but quite frankly the range of speeds is good and as of yet with the work I have done with this lathe have not found it lacking.
