Vacuum Metallising Chamber Upgrade

This is the current chamber but I have been having trouble getting below 10-3 torr. I've test everything I can and can't figure out any specific leak. There I said the word, leak. The curse of vacuum experimenters.

So I'm banking on it simply being a leak rate versus pump speed issue. I'm currently trying with this

A lovely Edwards diffstack I got on eBay. It's 4inch inlet which is great but I'm assuming it isn't keeping up with my cobbled together system.

So when I won some money on a snail race I decided to gamble again and get this from EVP in China

It's ISO250 flange so considerably higher pumping volume. 

This is the lovely trolley I welded up to accommodate the new diff pump and associated gubbins. Today I will mount the control panel back plate. Once it's in place I'll gradually transfer over the components from my first system. With a bit of improvement!

Now I just have to decide the layout that is an improvement on the earlier one. There seems to be a few guides on-line giving advice on 'Control Cabinet' layout. I'll have a read before committing. Anyway that was today's quest and it's finished. More to follow....
