I was in Glasgow on Thursday at Ross Hall hospital going to get a hip joint job done ,surgeon told me it was 90% successful , other 10% all sorts of glitches .I hope it's ok . Any way so I had not had a trip from Aberdeen to Glasgow with overnight stay and about an hour in the hospital , Ihad a ride along Clydebank to Dumbarton to the Denny Test Tank museum ,it was excelant the room where thy made the test props was fascinating all made to scale to match the hulls under test also the rudder development . Hulls first made of clay ,then wax then put on a bed and the wax cut of with a machine that was driven by line shafts, following a lines drawing . The girls were the ones tha did the tracing from the draughtsmens drawing because thy were neater .
If you have not been already it is worth a visit ,the sense of shipbuilding history and what has go on in that test tank. And a lot of it before electricity or computers ,a lot of clever men and women working there.
The tank was not working ,on inquiring I was told if a group vist was organised it could be up and running . All the same it was a good find ,
