THIS week's prizewinner is Mr. John "Gibb, of Motor Services (London) Ltd., London, W4. His idea concerns the removal of a broken blower shaft from the Rootes TS3 engine,

First, he says, remove the radiator and blower unit. After removal of the latter this gives access to the blower shaft, which is the length of the engine and driven from the rear of the engine. This shaft often breaks in the centre and if this happens it means that the crankcase must be taken out to facilitate removal of the blower shaft. If this is not successful then the gearbox will have to be removed. As the carrier tube is only the same size as the blower shaft there has been no other method of removing this shaft.

A method used recently, which involved the use of an electric welder, was as follows. After removal of the blower unit and radiator, the front broken part was removed—leaving the other half still in the engine. An electrode was then taken, covered in a plastics tube—any other material could have been used to cover the electrode provided it would insulate the electrode from the engine. Only the end of the electrode was uncovered and this was then marked off from the broken part of the shaft so that it could be ascertained when this was touched.

The electrode was then passed in the hole until it was touching the broken part of the shaft. The current was then quickly switched on and off, so that the electrode could not strike an arc and adhere to the shaft. The welding handle was then removed and the electrode pulled out with the broken part of the shaft on the end. After removal of the blower unit and radiator the whole of the operation took less than five minutes. Comments Handyman: Although I have several TS3 engines I have yet to tackle this problem. I have. however, used the electrode trick in other ways. On one occasion I used a 3 ft. by in. steel rod to weld to the inner broken half of an axle shaft, insulating by means of an ordinary garden hose. I am sure that Mr. Gibb will find other uses for this ver■ handy method.
