Smart & Brown Lathe L type

[john fletcher 1Participant @johnfletcher1]

Can any one explain how the brake works/operates on a Smart & Brown type L lathe.I have a copy of the manual supplied when new.Brake details are very vague to say the least and the brake wiring appears to be correct. Ted

Hi Ted

I had a look on the Lathes web site but there is only a short comment about it being fitted to the LPH type head stock, but there are no pictures or diagrams as to its construction. you could email Tony and see if he has any further information.

I have a model M so cannot really help further.

I have just had a look at a S&B "L" model C from Cambridge university which was used for instrument making. It comes with about 30 collets, a three jaw 5" self centering chuck and 2 x 4 jaw chucks 4" and 6". It is fitted with a 2 speed 3/4 hp motor and looks in very good condition and I am assured that it has been well maintained as it was used to make instruments at the university but I don't have three phase or much space in my shed. Could anyone give me any advice and is it worth buying?

You should be able to run it from a VFD. Have a read on the http://www.lathes.co.uk web site, I'm sure it will be considered to be a good lathe as Smart and Brown lathes usually are. It is limited to some extent as I don't think it has power feed or screw cutting capabilities. It all comes down to what you want to be able to do with a lathe.

The S & B model L is a specialised lathe intended for small work, it does not have a saddle like common designs. More like an oversize instrument lathe. Bear this in mind when thinking of getting one. If the motor can be changed from star to delta connections, you could run it from an inverter and have variable speeds.
