Lathe turning
I am having trouble with my shopsmith vibrating when I begin turning a bowl blank. I have tried to begin with a symmetrical piece, but still have quite a bit of vibration of my machine bouncing a bit. Any suggestions of weighting the machine down or other tricks you can recommend?
Re: Lathe turning
Which Shop Smith are you using?
How big is the bowl blank?
Is it wet or dry?
How are you supporting the blank?
What speed are you using?
How much experience do you have turning bowls?

Re: Lathe turning
dmz,
Welcome to the Shopsmith Forum.
Ron has asked several good questions which could affect the bowl blank being out of balance.
Addressing the added weight question, weight can be added several ways. This can differ a bit depending on the Shopsmith tool you have. A Mark 5/V is the most common and weight can be added by simply tying weight to the Bench Tubes. Don't overdo it and bend the Bench Tubes. Attach the weight on each end of the tubes. Another way to add weight is with the Universal Lathe Tool Rest (part number 555811) which adds 35 extra pounds and has a more versatile adjustment tool rest to get into those tight spots better. See it at the link below.

If you have the older Model 10E or 10ER weight can be added by simply placing it on the bench top but out of the way of your turning. Model 10's are already heavier than the Mark 5/V's at about 200 pounds without the bench. One of the reasons they are a favorite of turners.

Re: Lathe turning
Besides using the Universal Lathe Tool Rest, I also keep the jointer on for the extra weight.
