Urwick MetalMaster

Photo of Mick Collins' MetalMaster

Urwick had many good but unorthodox ideas about how a hobby machine tool should be built. He made a dozen) prototypes, but never went into mass production.

Notable features worth copying:

Adjustable centerline height
adjustable bed/spindle skew (for taper turning)
auxiliary bed for tailstock, DTI, lamps, etc
rack-feed tailstock
pulley/flywheel/vernier spin index
Urwick's Triangular Gib key is an excellent method of ensuring accurate and repeatable vertical registration on a commercial Mill/Drill.
A possible method of cutting the triangular way for the Gib key. See below - CuttingLongKeyways.pdf

Full plans, construction notes and CAD drawings are available on a shareware basis.

lathes.co.uk with some pictures, but the text seems to be about a different machine than Urwick's MetalMaster

The LaborMil, a similar machine, more heavily built:
