    Some ideas on it's worth.

    It is a Hercus, an Australian copy of the South Bend lathe. A fairly early version with adjustable cast iron head bearings my best guess made about 1950. Has a gearbox which is good. In reasonable OK condition is worth a minimum of $1000, possibly more. You can get an idea of prices on eBay and...

    Line boring bar idea

    Hi Baron, I thought that was an ingenious idea for cutting a key slot. The method I mentioned is used for a hole at right angles to the boring bar. Tony

    Generator plans?

    I would also be very interested in the design and calculations for an Edison generator. They look very good being driven from a horizontal engine.

    Line boring bar idea

One end with sharp corners. Then tap the hss tool through the hole similar to a broach. When a burr is raised at the...

    running a 14volt dc motor

    Hi, A source of a bigger power supply would be a lead acid battery charger. These typically supply 13.8v dc. Use one of the older type that do not have electronics that charge the battery at different rates. Tony

    Boxford 250 PC conversion

    Hi all, Thanks for the helpful comments. Maybe one of the posters might like to describe the operation of the existing Boxford controller. I have an IT background and had little trouble following the Mach 3 install instructions and getting Mach 3 to work. The Mach 3 manual makes it clear that...

    Hi from another aussie

    Thanks to everyone for their welcome. Mark: Thanks for your offer to source parts. I'm lucky in that the lathe appears to be in as new mechanical condition. It is 20 years old but appears to have had little use. So I'm hoping that the electronic retrofit will be about all is needed to get...
