With my syringes, I use maybe 5 cc a day. 5cc x 200 days = 1 litre.
A years supply is Pounds $14.50. That is cheaper than water based cutting
fluid and I don't have sump to clean out.

Hi all,
Just used threading oil with a brush. It got warm enough with 1/2" HSS, 390
RPM, 5.5ipm that a bit of smoke came off. Something like this could use a
chamfering pass around the edges.

had in the junk
seed oils are long chain fatty acids linked to a glycerin. Feed stock
for varnish and other coatings.
Enough double bonds so there is lots of opportunity for cross-linking.
With out dryers (catalysts) they just turn gummy. Organic cobalt compds
have been used for years as dryers for the

Lots of illocut products on web... which one do you recommend?
Indeed kerosene works well for threading Al and cutting. Probably less
flammable also but being lazy I didn't check the flashpoints.

Metoo almost, sometimes use LaTeX for

exactly that.

No. do not produce yet another board. You want to use an existing one.
There are so many in the under $20 range and even under $5.
John was talking about a controller with a dedicated keypad and LCD as
well as the buffering components you need for a breakout board.
Basically a souped up
