Based on G H Thomas' elegant and simple design for setting tools at centre height relative to the lathe bed (upper knife) or the cross slide (lower knife). The post can be revolved to the best position for setting most lathe tools including boring bars and parting blades. This gauge is suitable for lathes up to 6½" centre-height.
The kit includes drawings and construction notes together with the iron base casting, bar material and ground, hardenable flat stock for the knives.
