The idea of having a single machine that can be used as both a lathe as well as a mill/drill might sound good in theory, but in practise it is a complete pain in the rear end. Invariably my Unimat is set up as a lathe when I want to drill a few holes, or visa versa. I seem to spend more time reconfiguring the machine than actually being productive on it.
So instead of purchasing the attachment or going to the trouble of making one, you could get a complete separate machine such as this Sieg mill for not much more. Not only will it save you a lot of time and frustration, but it also has a far greater capacity.
The column on mine is 420 mm, but it is a Unimat Basic, which is not necessarily the same length as the Unimat 3.
