Brian it is possible to turn larger, take a look at number 2 here, that gearwheel being turned is 4.75" finished size so it is possible to do larger than 3" And having handled one of those Mery engine body castings she is working on in the mill I would say they are BIG
As I said in the message I deleted there is a lot of very detailed work done with these lathes and they would be a good investment compared with teh far easter types some examples of peoples work from their site
As Michael says if I wa slooking for a house lathe then this would be my likely choice
As you like the PMR engines this is a current thread of their steam drilling engine being done on Sherline machines though not sure how he will do the flywheel
