My son has a DB10 Super and like any machine it is built to a price and has good and bad points.
On the plus side:
The power cross feed is really useful, and makes parting off a pleasure. Although the minimal gearbox isn't much help with screwcutting (most threads require exchange of the changewheels) it is handy to be able to switch feed rates on the fly (although the machine has to be stopped to do this).
The ball clutch on the separate feed shaft is adjustable and has prevented several jam-ups. This is a feature that we wouldn't have got on a leadscrew-only machine.
The work envelope is excellent for the price, especially on the long bed version which we have. Well worth the extra if only because the tailstock can be moved so far out of the way – a real luxury when moving up from a mini-lathe.
The motor is adequate but a bit gutless, especially at low speeds, whilst the lack of a backgear means that we tend to leave the machine in the low range. To be honest we expected this, but realised that even if we had to buy a larger motor and VFD later, it would still be cheaper than the equivalent from Warco (This isn't criticising Warco, our other lathe came from them).
The variable speed means that I can increase the speed as the diameter reduces when facing or parting.
The backplate design, which uses a rotating collar and three bolts, is almost as quick and easy to use as a camlock.
The slotted cross-slide means that it is possible to fit a rear toolpost or to bolt down a part for boring.
On the down side:
The emergency stop button on top of the headstock is awkwardly placed and duplicates the adjacent stop button. After we move I plan to relocate it to the tailstock end.
The motor is really gutless at low speeds (but on the plus side, providing you hit STOP immediately, a stall is less damaging than breaking things).
The toolpost sits on a boss which is integral with the compound slide, so that to fit an Aloris type toolpost you have to either bore out the toolpost body and cam (Chester will do this if you order the toolpost with the lathe), which can only be done with a piston type, or machine down the boss and make an extension for the stud. We chose the latter option, which means we can fit the wedge type later if we wish.
The lathe comes without a faceplate.
The swivel mounting for the compound slide is clamped down to the cross-slide with two bolts in the same way as a 9×20. As a result it is rather flexible, although to be fair, this seems to be the case with most (all?) similar lathes. Replacing this with a four bolt mounting is on our "to do" list.
The carriage does not move a full number of millimetres per revolution, and as a result the scale isn't as useful as we hoped, normally we set the tool to the end-point and just zero the scale.
The tailstock is designed to take a morse taper without a tang, and several millimetres of travel is lost if you use a drill with a tang. Worse than this however, the end of the screw is small enough to fit inside the thread of a drawbar type taper so that it cannot be ejected. Easily cured with a screw-in plug but annoying.
Are we happy with our choice?
Yes. The lathe is nice and solid with a work envelope that suits our needs. The machine was a good price, especially as it included the cabinets (even though in our case it it fixed to a workbench and the cabinets are stored in the loft). Its best features, the separate feed shaft with overload clutch, the chuck mounting and the basic screwcutting/feed gearbox are all things we couldn't add later, whilst its bad points can be fairly simply fixed (although I might try the low range conversion that was featured in MEW for a Warco before splashing out on a VFD).
