I watched this again for the 3rd time and the only time you will see him applying cutting fluid with a brush is in the first scene where he faces the stainless bolt – after that it is all dry .
Not wishing to be pedantic..Look at 1:24 thru 1:34 or so – clearly see oil running down the sides of the cylinder while drilling. Just cos we did not see the brush does mean it was not applied. – a Chap with the skills he has would do the job right, I think..
Right you are Joe !
This time i watched with me glasses on 
I also noticed what could be some smoke coming off the lathe tool in the machining operations that were shown speeded up so he may have had some fluid on in those operations as well.
Looks like he has a cnc Sherline lathe and possibly a cnc mill also.
