Pete I first worked on the Oberon Sub's and as I'm small bloke they threw me in all the small sections anyway I had had had enough so told the foreman I quit he said to me go talk with the supervisor in the machine shop.

Well I went and saw him where he gave me a drawing and said do this on a horizontal borer, now as I looked at the drawing I didn't see a reference point to to draw too. So
gave him a reference point to use then I got told I got the job and the foreman needs a talking too.

So my babies were 3 machines where I refreshed the bores on the ferry props, now as they were a tapered bore a 3 thou cut was enough to reform the bore but 4 cuts were need to get a polished bore.

Then I got thrown into the heavy section where the job weighed 360 ton and we had to put a 150mm bore thru dead centre so we used a high speed tool ground in the grinding section and had a 15 metre floating shaft with a 1/2 thou cut doing 2 rpm. It was a joy to do this job which got me this old school mentality.

Then this old guy came over and showed some turbines on the wall saying they are 3 times the size and I'm here to teach you how to make them. Now hammering copper wedges. and turn the turbine to keep balance is an art I learned

Now when I lost that guy as he died I did think with what I learned could go further but sadly what I learned stayed there as I had to sign a clause.

I've only been to Tasi once and yes it was thru Launsestion  and if I knew you back then I would of called in.
