I'm amazed your date has any stamp left after that! ;-)

Yes I got carried away :clap:

I decided that the Rohm rotating centre was too vulnerable rolling about on the bench. I don't want it in place in the tail stock except when in use, as it's a nice spiky thing to catch yourself on, when setting up tools. I had intended just to pop it in a suitable hole in one of the Versatol Cabinet shelves, but due to it's length I'd have to lower a shelf and waste a lot of space.
Reconciling myself to making a wooden box that stopped when I realised that my bottle of 'Resin-W' PVA glue was congealed beyond rescue- so what to do :scratch:
Then I remembered an Acramill collet chuck box - no idea what happened to the chuck, I think this came as part of a job lot with no chuck, just the collets. So the remaining collets were ejected into my box of Acramill bits and the box 're-purposed'
A simple wooden divider with a hole in it to take the business end, an other with a slot (so it would go in) for the 4 MT shank, and a third loose bit to stop the centre sliding up and down. Then the two shaped dividers had a recess cut in them to hold the nose spanner.
I'd intended to screw through the box into the wood, but realised that it would very likely split. So rightly or wrongly I chose to use 'structural adhesive' Horrid messy stuff and I totally failed to tidy it up neatly. Not really happy with the result but at least the centre won't now roll off the bench!
Long term I will probably re-make the dividers in an engineering plastic that will take a thread, so can be safely screwed from the outside of the box.

If you'd pilot drilled they wouldn't have split, Andrew.

I'm not convinced, it's only softwood.
Time to sort out the coolant: There is an external motor / pump unit rated at 20 litres / minute that sits on the coolant tank, draws up through a mesh filter, then passes coolant to the machine though a 125 micron hydraulic filter.
I started by undoing the filter housing - it was well choked with plastic swarf. It will clean up reasonably but I'd like to put a new one in. The actual element is a UC.R.76115 and googling so far has found that for what they are, they are a silly price (£30 plus the VAT). Hopefully I'll turn up a cheaper alternative. The only 'special thing about it is that the inner mesh
perforated tube is stainless to avoid rusting.
I intend to prove the pump and filter 'off line' using a bucket rather than fill the tank with it's 95 litres and then find the pump doesn't work!
All the nylon re-inforced hoses will be replaced as they've gone rather sticky with age.
