Arvid,
I'd suggest the full synthetic, mixed at a higher concentration level for lubricity because of it's keeping qualities and the fact that you're in a basement shop. The Tri-Cool TC-1 I use has virtually no smell whatsoever, so it may be a good choice. It's mixing chart shows it can be mixed to (I think) as low as a 10:1 ratio.
I also have ValCool VP-910 full synthetic in my surface grinder, but had to give up my 5 gallon pail to bail out a friend. It's very similar to the TC-1 and cheaper in the 5 gallon pail. I should just bite the bullet and get a fresh pail of it. I get the same evaporation rates with that though it's got a more perfumey smell to it.
