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

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