Hi all,
I know this is an old problem and i have used the search function both here and on Pen Turners Paradise to no avail...
This is my problem.
I have the dead centre in the headstock - Runout is less than a thousandth.
The live centre is in the tailstock and runout is the same as the headstock dead centre.
I line up the centres and lock the headstock so that the points are aligned.
Then when i turn something it is not round...
Turning is done between centres so no mandrel to bend.
I tried using a blank brass tube mounted on the bushings and that is where all the runout is happening!
On both bushings the runout is almost a hundredth of an inch!!
This is also translated to the brass tube.
Do i need new bushings??
Or is it time to try without the bushing??
I am going to glue up a tube in some useless wood and turn it without bushings to see what i get.
Any help appreciated!!!
