Thor, or should that be Zeus?

[m_c]

I'm thinking of different ways of doing the WC on the new machine under construction. Maybe a filter and maybe pumps / valves arranged so the water is emptied back into the reservoir at the end of a session leaving the spindle dry. Someone will probably tell me that it will be worse if it dries out . . .

It will be until it completely dries out.
Far simpler option is to put some anti-freeze (or summer coolant) in, as it has corrosion inhibitors in, and will improve the cooling performance over plain water.

I was originally thinking of using distilled water (Or RO water) but water is actually very corrosive if it's pure water (Has a low EC or TDS reading) which I forgot until I read your post. Antifreeze has got to be the best choice but added to distilled water (Or RO).

Good thing about using distilled water is you should get no scale.

Exactly what i am doing. Running it on the most expensive antifreeze and distilled water. The pink one. But after 2 years maybe from the heat here in Spain, even in the antifreeze tank something develops, like a veil or to say like a jelly . So then it has to be changed or just cleaned. I highly recommend the antifreeze to be in a transparent tank so you could see if that happens to you.

If I was using a water cooled spindle I would be thinking about fitting one of these; https://www.fernox.com/filters/tf1-compact-filter or similar, they collect all the crap and have a very strong magnet.
Do addatives for central heating work for spindle cooling systems ?

When we replaced our boiler a few years ago we fitted one of those and it works a treat. Traps the black (iron oxide?) which comes off the inside of the steel radiator panels and keeps the boiler matrix clear
But spindle is chrome steel I think and pipe and pump blades are plastic so not sure it Fernox filter would work? The stuff that blocks my spindle is more like salt deposit which I guess comes from the liquid itself. I'm using fancy bottled PC water cooling liquid but may switch to buying distilled water and adding some antifreeze.

I have fitted many of these type and are great in central heating system to collect the iron deposits , I am not so sure they will work with the spindle. I use this stuff http://www.eurocarparts.com/ecp/p/ca...KidhoCSLzw_wcB and a bit of antifreeze and never had any trouble.

My spindle rusting from the inside out doesn't sound good :(

Why they didn't add £30 to spindle cost and use a stainless steel tank you have to wonder at least the option would be nice.

I have a Reverse Osmosis filter which essentially produces the same as distilled water so I will use this for my system with some blue antifreeze as I have a 200l barrel at work lol.

Has anyone tried one of these, looking for an attachment that I can use to grind on Thor.

That dust will sand the rails and ball screw if everything is not airtight. Just the thought of it will make any machinist shudder . I guess i am becoming a machinist

Chaz - that looks suspiciously like a ready-built grinding spindle for the Quorn tool and cutter grinder. This was a design from 1974, sold as a kit of castings and hard-to-get materials. Quite a lot of kits have been sold, and some of them actually built! From that point of view, it's a tried and tested design with nothing exotic about it. The original used labyrinth seals (a series of fine grooves) rather than the lip seals in the advert but maybe materials have improved in the last 40 years By all accounts, they work very well for fine grinding and people use them as toolpost grinders in lathes. Light duty, though - not for heavy-duty work. Plenty of references to the Quorn via Google. I have a set of castings under the bench that have been maturing for the last 30 years or so - come back in 10 years and I'll tell you how it works from personal experience...
