Update: I tried to attach my chuck/adapter setup to the aux spindle, but the shaft is slightly larger than the main shaft on my machine. This prevented the adapter from sliding over the aux spindle. I am not sure if that is typical for mark v machines or if it is a defect in my machine. I ordered ...

RF Guy,

That is an interesting thing to look out for. I have considered my chuck jaws being the cause of my vibration issue, but I am still getting the vibration using a worm drive screw. While the jaws do secure the screw, I think the metal-on-metal contact between flat surfaces would be ...

David,

Mounting on the aux spindle is a great idea! I'm not sure why I didn't think of that. I'll give that a go tonight and see if the vibration continues. To your second point, yes, I can feel side-to-side play in both the original quill and the used one I replaced it with. I will do some ...

Thank you both for your responses.

The vibration occurs constantly whenever I have a bowl mounted without support from the tailstock. I use a Nova G3 chuck with a worm drive screw to turn the outside of bowls and to put a tenon on the bottom. Then I flip the bowl around and mount it with the tenon ...

I am pretty sure the blanks were balanced. I have made attempts with several different pieces of wood. Each was a different species, and each was turned round. In every case I am getting the same vibration. I think the problem lies within the machine since there is play in the main shaft. Is there a ...

There is vibration at the lowest speed (A), and it gets even more aggressive as the speed is increased. The blanks that cause vibration are about 6-8 inches in diameter. They should be balanced since I take passes until there are no flat spots and the entire circumference is cut. So you’re thinking ...

Hello folks,

I have a mark V that was originally purchased in 1978. I bought it used a few years ago. Whenever I try to turn wood bowls with a chuck, the machine vibrates fairly aggressively. This persists even after I turn the bowl blanks round. The machine does not vibrate when turning between ...
