For Sale: Pinnacle Model PBM 450A universal tool and cutter grinder. Manufactured 1988 but in excellent, lightly used condition and, being highly versatile, is the ideal machine for the smaller workshop.

It has the major parts of the ‘finger’ support but lacks the actual finger, a part that is easy enough to make. Also included is a hand-held diamond-wheel dresser, which could be adapted for mounting on the finger support base or similar. For convenience (it can, of course, be removed and still has the (detached) levelling feet). At the same time, I moved the suds tank and pump to the outside to allow the interior of the stand to be used for storage – a shelf was fitted but is easily removed. The suds pump is not connected to its hoses. There are two start buttons at the right-hand side of the base – the top one is for the main motor, the bottom for the suds pump; both are 3-phase 415 volts. An operation and service manual is included. £1250
