Fr YRE inflation can be simplified using the OPW tyre inflator now marketed by J. S. Webber Ltd. With this unit, the required pressure is preset on a dial on the handpiece and when the chuck is attached to the valve stem of the tyre and the control depressed, air is admitted until this pressure is reached.
Two models are available, one for car tyre sizes with pressure settings from 15 to 45 p.s.i. and the other for truck or bus tyres with pressure settings from 10 to 110 p.s.i. The inflator is compact and easy to handle and complete with 12 in. hose and chuck weighs only 23 oz.
Marketed by: J. S. Webber Ltd., 6 Stanley Road, London, E4.
Price: Ell 8s. with 12 in. hose and single chuck; i13 17s. with 12 in. hose and dual chucks.
APNEUMATICALLY operated orbital sander has recently been introduced by The Aro Co. of High Wycombe. Called the Model 8444, the sander fits comfortably in the hand and weighs less than 4 lb.
It has a powerful stall-proof air motor driving on a in. orbit. The bottom plate measures 74 in. by 3i in. and this can be fitted with interchangeable a in. or 4 in. thick felt or rubber pads to cater for both flat and contoured work.
Quick-acting paper clips enable the machine to be speedily loaded with up to 12 sheets of abrasive paper and there is provision for piping away the exhaust when it is desirable to ensure that oil or water from the air line does not spoil the workpiece.
The sander can be used for woodworking, reinforced-plastics preparation and vehicle bodywork finishing and the tool has already been adopted as standard equipment on the finishing lines of two British vehicle manufacturers.
