Right, I thought that might be the one, although the model I saw didn't have the copy facility - at least, if it did have, it wasn't fitted to the floor model.
The main concern I had was the lack of power for the size and the relatively flimsy locking handles. Otherwise, the construction was typical of far-Eastern imported lathes, with slightly rough castings and a bit of a flimsy stand.
The difference between this one and your current model would be considerable, but I'd have a look at
this one from Axminster's Perform range, which has a much better power rating. OK, it doesn't have the copy facility, but that's actually no big deal as far as I'm concerned, for most general turning. I don't think the headstock swivels, but it slides along the bed, so you could turn a large bowl off the end. Even
this one is a better bet, with swivelling headstock and a bit more power than the B & Q model.
I know that Chas has a Perform lathe, which he's pleased with (you might try a search of his posts for more info, as I can't remember which model he's got).
I'm still prepared to go back and have another look at the B & Q one for you, but it looks like Monday will be the earliest opportunity. Lack of power is still my major concern and I don't think the copy facility is worth trading for more power. HTH
Ray.
