Trevor Posted January 3, 2021 Report Share Posted January 3, 2021 So I am a new to turning. I am working on an urn and I have been turning between a drive center and a live center, so in essence spindle turning. I need to start to hollow it out so I mounted to a faceplate now it wobbles when I start up the lathe. How do I achieve a wobble free face mount turning.?tia Quote Link to comment Share on other sites More sharing options...
BonPacific Posted January 3, 2021 Report Share Posted January 3, 2021 I'm no expert, but generally I think of a face plate as part of the first stage of turning something, where you've yet to establish a good stable shape. Trying to mount a faceplate after already doing some amount of turning sounds like a nightmare to get squared/centered properly. Do you have a chuck? 1 Quote Link to comment Share on other sites More sharing options...
JohnG Posted January 4, 2021 Report Share Posted January 4, 2021 Yeah probably should have started with the faceplate. If you don’t have a chuck and are needing to use the faceplate to hollow it, you’ll just have to turn down the outside until it’s in round again. 1 Quote Link to comment Share on other sites More sharing options...
Popular Post Mark J Posted January 4, 2021 Popular Post Report Share Posted January 4, 2021 @Trevor , I don't' suppose you could post a few pictures? I'm having difficulty how you mounted it to a face plate after turning the outside of the form between centers. In the meantime I can throw this out. When re-mounting a partially turned piece precisely maintaining the alignment is key. There are lots of trick for this depending on the mounting and transfer that is being contemplated, but when transitioning from centers to a face plate or chuck you want to keep the live center engaged in the dimple that will have been formed (either by the live center or the drive center). This centers the piece on the tailstock and if the foot is flat or the tenon is true then the piece can be mounted on the face plate or in the chuck and should run true. The operant word there was "should". There are other factors which can effect the alignment. For example if the wood is green then it will start drying and changing shape. 3 Quote Link to comment Share on other sites More sharing options...
Dave H Posted January 4, 2021 Report Share Posted January 4, 2021 If you were turning between centers you have all the information you need. You just need to figure out the dia. of the face plate, then set a compass to the radius (half the diameter measurement) you have the center point of the piece you were turning, put the the point of your compass in the center point of your turning and swing a line the dia. of your face plate. Now mount the the face plate on the circle you've drawn, if it's nots running true then your face plate is out of round or, it could be warped either way you would need a new face plate. Good luck 2 Quote Link to comment Share on other sites More sharing options...
Trevor Posted January 4, 2021 Author Report Share Posted January 4, 2021 I have a chuck but I think the urn is too tall or heavy at the top end. I am thinking a steady rest should help. I did try just turning down the base end and putting it into the chuck. It works but when I bring the drill bit in with the tail stock it wobbles more.

wtnhighlander Posted January 4, 2021 Report Share Posted January 4, 2021 Weight distribution for end to end should not matter, if the base is perpendicular to the center line of the shape, and the chuck (or face plate) is seated squarely against it and centered. Does the piece vibrate while you spin it between centers? Quote Link to comment Share on other sites More sharing options...
Trevor Posted January 4, 2021 Author Report Share Posted January 4, 2021 I cannot say for certain, this is my initiation into turning. The lathe did like to walk, but I bolted it down. I mean I am able to ramp the speed up over 1000rpm between centers. When drilling out I imagine it should be done at lower rpm is that right? Also it was a wen chuck that I am using, is it just because it is a cheap chuck? Quote Link to comment Share on other sites More sharing options...
wtnhighlander Posted January 5, 2021 Report Share Posted January 5, 2021 I can't speak to the chuck, but low quality is a possibility. I assume you are drilling with a forstner? If so, definitely slow down. Those bits are not designed for such high rpm. 1 Quote Link to comment Share on other sites More sharing options...
