Thanks Floyd, I will try to get a better video and show it in more detail. I keep it lubed with WD-40 and it works great. The brush is mounted to a jig and it can slide in a piece of T-Track I attached behind the lathe. I do have some photos on my website that you can see better.
 
Great video Lee its neat to see stuff like that. i have only worked with a metal lathe a couple of times when i'm at my inlaws, i made my dead center on it. i'am courious though i didn,t have any smoke when i turned the dead center but at the same time we did not use any kind of colant is that where the smoke is coming from?
 
Yea Shane. I am using WD-40 for cutting oil, carbide bits and a higher surface speed than normal. (but still mild compared to modern CNC stuff)

It's hard to see in the video, but I designed a "chip brush" to rest on the stock and it stays sprayed with oil to keep it lubed. It works almost as good as a "coolant stream" system. I normaly have a box fan sucking away the smoke, but I turned it off for the video so it made more than what is normaly there. One of these days I plan to mount a high-cfm bathroom fan in the wall and vent it outside all nice and neat.

Here is a better view of the brush system and a nice shot of my custom made motor slide hinge. (Spare Ryobi table saw parts) :D

Lee... you've got a nice setup there. I think the bathroom vent fan in the wall is a great idea. I was under the impression that metal turning went at a fairly low speed. About how many rpm's are you doing in the video?
 
Yes, it is done much slower than wood, in the video the lathe is only running 753rpm, but I can bring it down as low as 150. For 1018 steel, 1" should be about 300rpm. However, with the carbide tools and the oiled surface, I can get a much better finish kicked up higher. Plus, I am turning mostly under 1" and the next speed I have for 1/2" is about 650rpm so it's not too bad. It is where the lathe feels good cutting and the metal has it's best finish in the range.

With the 1018 CRS I can pull a max of .040" in a pass, but you loose a bit of the finish. .020" gives me a much better finish. I can take a fine cut of about .003" and keep a "cut" for the most part.

What was a major help was I figured out how to set up my gearing to feed the carriage so I don't have to do it all by hand! It's not faster, but I get much more enjoyment from it.

Thanks for the comments, I can't wait to pick up the vent fan, it will be so much better in the shop!
 
Interesting stuff. Was never into metal turning but I will have to go and get some lessons from my brother. Then try to acquire a small machine (After consulting SWMBO of Course ):D:D:D
 
You try running a lathe and hold a camera in the other! [}:)]

My wife did say that she would help video it for me so I will update and provide a better video some day soon. I also have a friend who is a professional camera man and does some freelance stuff, I might see if he has time the next time he is out here.
 
I see that you are using the link belt to turn the lathe. I have that type belt on all my automobiles and trucks. It does make a great difference in vibration dampening and also I feel like the motor is transferring more power to the attachments and little is lost due to slippage. They are worth every penny - in my opinion - and well worth the effort to add them where ever v-belts can be changed. Just the reduction in vibration at the table saw is worth the investment.
