still working on my turret basket internal frame machining down the oversize angle. Such a shame the original just turns to powder.

Done a test fit and all appears to be a good fit. It just seem to be highly over engineered.

Of course it is over engineered ... it's British!

Great, it all fits and the next fab job is the turret stays. I will make a press tool bar to make these as they are about 900mm long, tapered and a 180deg return on each side for strength.

The stays are 3mm ally and they are tapered 200mm out to 340mm. I made a former for my press brake to get the 180 return on both sides. They are extremely rigid once pressed.

They are secured by 7 bolts at the bottom and then another 3 at the top of the turret basket. It's seems quite odd but they are not symmetrical every stay is a different angle and a different distance apart. That alone is going to be tricky to mount it to the turret and have it traverse within 10mm from centre
 Once again, I guess they had their reasons.

Hi Colin.
Are the stays perhaps the best ‘compromise’ for access to the guns and the balance of the turret? David

Spend 6 hours making a tool that does 3 perfect passes and is in use for all of 5 minutes. Sounds about right.

Hi David, I guess it must have been the best idea. Access in these small tanks is very limited and I no doubt they would have tried numerous other methods. As the stays are all different in symmetry, they must be in specific locations for ease of equipment accessibility
. I'm sure it will become clear as I progress  Terry, that's part of this job  spend hours of prep to get minutes of results

After checking the centre of my fabrication, I was very pleasantly surprised to see I am within 3-4mm off centre and that is quite a relief. Also yes the inspection plate in the floor is meant to be non central
