- An excerpt from the DVD "I have a lathe. Now what?" by Ron Brown. This is a complete chapter on determining the proper speed depending on the diameter of the work piece. How fast should you turn a 10 bowl blank? A pen blank? a 3 inch table leg? This clip will tell you. More info available at www.coolhammers.com
14 year old video, still relevant! Thanks for the simple explanation. Ill try not to lose any fingers.
As a total novice to lathe work, this has been of immense value to me. Thanks.
Excellent tutorial 👌 I always say a little paranoia can save your life. After having a few things turn into shrapnel and end up all over the shop I am more than a little paranoid.
Wow, 10 years ago you posted this. I found it useful in 2019, thank you Ron! :)
Good points Bernhard. Thanks for your comments.

Excellent video. You've eased a lot of my anxiety with your lesson. I was panicking trying to find the correct speed to turn stuff at but this has certainly calmed the mind. Thank ya!
Jordan:
Always start at a slow speed, then speed up until it feels right or you begin to get excessive vibration.

@vljenewein : Now I know what a duduk is! You are going to need a few different speeds depending on the particular cut you are making. For drilling the inside much slower, maybe 1,000 rpm. For shaping the outside between 2,000 and 3,200 rpm. If the wood is burning slow down, If you are getting chatter and vibration slow down a bit. Top speed on my Powermatic 3520 is 3,250 rpm. I often run close to 3,000 for small stuff and as slow as 100 for bowls. Good luck.

Beav:
It works well for diameters greater than 5" or so. Below that, after initial roughing for balance, I just run pretty fast. On small diameters like spinning tops or pens, I apply TLH speed controls (turn like heck). Easy rule: Large Diameters = Slower speeds, Small Diameters = Faster speeds.
Good turning and God Bless.

Thank you!!! Needing to learn lathe basics to turn Apricot 2" x 2" into a duduk.
This will be on my lathe in sharpie very soon Thanks
Very interesting, curious to know where that formula came from. I’m still pretty new to this but have heard that faster speeds will provide a better cut. Some experienced turners even go up to 3000rpm as a normal practice (or so I’ve been told).
A good rule of thumb is to turn large diameter pieces slower, to begin with. Smaller pieces you can start out faster. My technique is to start slow then increase the speed until I'm beginning to be afraid or the wood is burning from friction. Then slow down a little bit. I regularly turn small diameter items as fast a the lathe will go, for wooden pens that might be close to 4,000 rpm. For bowls, I might start at 2-300 and finish somewhere around 1,200 depending on the diameter of the bowl.
Super informative, thank you for posting this video.
I did find the music annoying and got in the way, however.
Still, I'm a loyal subscriber!
Good info to know.

Are you asking a question?
Does the hardness of the wood matter?
Ahhhhh, what?!
Yes! Everything matters. What matters most is balance. Even when the vessel is round, it may not be balanced, due to differences in density, a knot for example. This formula is only a guideline, a starting place. The best advice I can give is begin slow and see what you can get away with always erring on the side of safety. This formula works for plates, platters and bowls, not well for spindles.
