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.
Ignore the small hole along the opening. Just grabbed a scrap of angle that I
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

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.

reverted to a 5 cc syringe with a thin needle and I spot the material or

You guys all probably know this but I'll say it anyway.. You should start
using carbide endmills. I run a tooling company here in New Zealand
selling to the local machine shops. Carbide is awesome. Anyway I have a

John,
Do you have flood coolant or mist coolant?
I would be inclined to try the cut full depth if you have flood or mist
coolant. 1/4 inch is on the borderline of having the strength necessary to
make a full depth cut. I would think 5.5ipm might be a little aggressive
but I would leave it

I'm trying to figure out, using Machinists tool box, exactly what feeds and
speeds could be used for milling the slot.

Ok, first of all you have permission to laugh but here is my rule of thumb
This is meant for a hobby situation not for industrial situations
where trimming 10 seconds off an operation means the difference
between profit and loss.

Being new to cnc lathe setup I have to ask about feeds and speeds. How
does one know what feeds and speeds to use on the lathe. On my desktop
mill I mostly cut aluminium and I have a small spindle so the speeds are
as fast as the thing can handle. Not very scientific.

Lathes are pretty easy, you will basically end up always using the
