[QUOTE="Bullet bumper, post: 1307962, member: 17844"] I don't think the 1340 has a foot brake. Just so you are aware of how things work. With a lathe without an instant stop foot brake you will need to use your thread cutting dial and disengage the half nuts every time you cut a shaft thread . However if the lathe has an instant stop foot brake you can cut a thread up to a shoulder stopping with the brake and withdrawing the tool at the same time . Then just restart in reverse go back to the start , stop , wind into the next cut and start in forward. You don't have to disengage the half nuts. On top of that you have a good convenient safety stop in case you get caught up . A good thread can be stuffed up by just miss reading the dial or miss engaging the half nuts . A lot of people think you have to have a 3 phase instant reverse motor to do this. You don't the relay system in the instant stop foot brake allows you to do it with a single phase motor also as it brings the motor to complete stop and then you select reverse to back out . Many professional machinists like power they don't like any lathe with less than 5 hp . However that is not always the best advice for armatures. You can do everything you will need with 2 hp . A single phase motor lathe is much easier to sell later and much easier to move to another house where 3 phase may not be available . Also way cheaper to replace motor if it breaks down and way easier to buy . I had a mate who set up a workshop full of nice old 3 phase machines . Spent a fortune getting all the 3 phase all wired up . However he lost his job and had to move to get another one and could not afford to do it again . So his machines sat in a garage for years unconnected . We never know what is ahead of us so my philosophy is keep it as portable and sellable as possible . [/QUOTE]
