Bush DAC 90 DAC90A Dial Cord

Hi how long would it take in the assembly line to fit and calibrate a Bush DAC90 or DAC90A dial cord kind regards Bob

Hi Bob.
Most likely a very few minutes or even less. The ladies that were the mainstay of these lines were extremely skilled and well trained in how to do this very quickly. I don't know if there is any footage of DAC90A production but it would be interesting.

I've recently restrung the dial cords in a few DAC90A sets and always found it to be not an easy task. The actual restringing isn't all that difficult but if the manufactures instructions are adhered to, attaching the tension spring to the tuning drum can be difficult. Repositioning the drum as shown in the second attachment makes the task easier.

Hi.
I use a hook tool I got when fixing pressure washers for removing seals from the heads. It works great with hooking on the spring to the drum.

Why did you have pinnipeds in the toilets?

Also, using a pressure washer to remove them is pretty cruel...  and probably messy!

Ha Ha
It's amazing what we got up to.

I had to look up pinnipeds as it is a term I have never heard. 'Heads' I have though, in submarines. It's not sounding too good to me either, at least for the seal. Are the outlets open to the sea? - Although there would have to be some kind of valve through the pressure hull. I can see a pressure washer would be essential and no using at all when sitting deep.

Hi.
We used three phase machines on larger species like whales, they didn't have any seals but the "O" rings in the blow holes caused a lot of trouble, the hooks we had were pretty useless.

An extract from 'Nelson to Vanguard: Warship Design and Development, 1923–1945 By David K. Brown' explains submarine heads around the end of WWII.

'A feature which was warmly welcomed was the installation of a sewage tank.
Previously the heads had to be flushed each time they were used, the contents of the pan drained into a pressure pot which was then blown into the sea by compressed air.
This had two hazards; the bubble might give away the position of the submarine (permission always had to be sought to use the heads), the other was that maloperation
of the complicated system of valves and levers might lead to the user suffering the fate known as 'getting your own back'. '

Thanks for the update Jim. It's not something I would have thought about but I have heard of 'getting your own back' before and, with Trevor's comments, realised about water pressure. It's perhaps something I could have asked about when I toured the submarine in the submarine museum at Gosport but there is so much to see anyway and details don't come to mind at the time.
