A very popular lathe manufactured in the USA www.sherline.com although originally designed and made in Australia in 1970. Spare parts readily available as is a large range of accessories. A very large enthusiastic fan base.
The machine has a very good reputation for quality and reliability. The motor is variable speed through an electronic controller. The motor and headstock can be swiveled a small amount to allow taper turning, enough for production of canons. The motor drive is through two step pulleys giving a high and low range of speeds. The spindle can be driven by hand if required, primarily for screw cutting but this is also useful for delicate pieces. A long bed version is available for those wishing to turn masts and spars The bare lathe price is $575 and $675 for the long bed version.
Among the aftermarket accessories the Sherline is blessed by having available a dedicated replicator tool. Just the thing for making 100 canons for a first rate.
