Usually I think it refers to a 7" swing (max diameter) with 10" between centres.

I thing the first number is the maxium diameter before the work touches the bed and the second number the distance between centres. (In inches.) I think they are basicaly sieg lathes.(Like those sold by Chester, Warco and Axminster.)

Les is quite correct – I have a 1224 warco so its got a 12" swing and 24" between centres

7×10 is the maximum diameter (7in) that can be swung vs the bed length (10in).

In simple terms it's what ye olde worlde calls a 3 1/2" lathe.

The American term sounds much more impressive

Yes, typical Mercans. All shirt and no trousers. Quoting the diameter makes your equipment sound more impressive than quoting the radius (centre height) as we modest Brits do. But it's not how big (you say) it is, it's how you use it.

thought it would be simple.

i was thinking chuck size and centres.

right now i can visualise what size lathes they are talking about.

thanks.

Usually the 7×10, 7×12, 7×14, 7×16 refer to mini-lathes, usually by SEIG or Real Bull.

One of the American companies claims a 16" bed but requires the tailstock to overhang the end of the bed by 3/4"! (It's in the manual!)

Talking of Mercan marketing liberties, you'll see that DeWalt (Black and Decker) in the UK sell an 18V Li-Ion product alongside their 18V competitors. Naturally in the US, some creative marketing genius decided that they should sell it as "20V MAX". It all seems rather pathetic viewed from over here but I bet the guy is regarded as a bit of a god. I'm sure it sells products to gullible punters. As you say, it's the Mercan way….

Funny thing is, if you buy a pair of trousers over there according to your customary UK size, you will discover they are 2" too big around the waist. Somebody must have decided to knock 2" off the size tag, presumably to flatter the customers. Marketing genius at work?

Here in some shops they sell DeWalt at one end of the shop, and Black & Decker at the other, same tools, different colour, and much different price, and some people wont touch the B&D, it's cheaper so it can't be as good.
