My wife must have noticed the number of times I stopped to look at the Delta midi lath 46-460 as she gave me one for Christmas. I have been turning wood on my small metal lathe and this will be a welcome addition to the shop.
I just couldn't wait until I built a stand etc. so I placed it on the floor and turned it on just to watch it go round. Now for my question. Is a little vibration normal under these circumstances. It is strange in that it appears to be motor speed dependant but not spindle speed dependant.
In the low speed belt setting you can feel a little vibration in the base but you do not hear nor see anything. As the variable speed control is advanced vibration begins to where at the top of the speed setting for the low range it vibrates the floor enough to shake tools on a table several feet away. Shifting to the high speed range the vibration is gone with the variable speed control at a low setting even though the spindle speed is greater than what caused vibration at the low speed belt setting. As the variable speed control is advanced the vibration appears again near the top speed setting.
Has anyone had any experience with this? Is it likely to not be an issue after the lathe is bolted to a heavy, sturdy stand?
I want to be clear that we are talking about a small amount of vibration. The lathe does not vibrate enough to move around the floor even though it is just sitting there not bolted down or anything. You can just barely feel the vibration at teh low motor speeds and what you really notice at higher speeds is the noise made by vibrating tools on metal shelves a few feet away.
Any advise or comments would be appreciated.
