A N important accessory when erect!". ing an engine and gearbox is the sealing compound used for making the various joints. Some fitters prefer one that is slow setting, so that the joint can be made at leisure, instead of having to be governed by the setting time of the compound.
Plastic Hermetite 1310 fills this need; in fact. it never really sets. For example., a freshly made joint between an engine and a gearbox had to be broken twice, hut there was no need to remake the joint befbre the gearbox was finally bolted up.
Herenetite 1310 is of fairly thick consistency and can be spread with the finger. There is never any need to use any form of gasket, Hermetite products are made by the Kenilworth Manufacturing Co., Ltd., Hermetite Works, West Drayton, Middx. This company are also respon
sible for Hermetal sealing putty, which has a variety of uses. It is made up into a paste from a powder, the liquid being added until the mixture becomes suitable for spreading without shoWing any tendency to•tlrop away.
During the assembly of an oil pump. the fitter was unfortunate enough to shear off one of its holding-down setscrews, which broke off flush in the crankcase. A quantity of Hermetal was applied to the edges of the joint face in the area of the setscrew and the setscrew hole in the pump body was also filled with the paste_
It was purely a try-out, but as there has been no sign of a leak, replacement of the setscrew will be delayed indefi
nitely. When set, Hermetal can be treated as part of a component and filed or otherwise made to conform to any desired shape.
