Mick,
Similar to Mick ,for me it is most important not just to clean the machine at the end of a session, but also to fully oil it both before and after use, especially with machines that are kept in a shed. Yes, this does mean an excess of oil, but since my machines use pumped cutting oil anyway, it really does not go to waste. And, given the replacement costs of machines, I believe better a little to much ( relatively cheap ) oil than the onset of the dreaded rust bug.
Trevor T,
Yes, I do have small but separate swarf bags, and although I do not produce vast amounts of swarf, when combined with other scrap it makes a single trip to the scrap yard viable, especially since very fortunately, it, and the dump-it site are across the road from each other.
Trevor.
