Help with Viceroy Lathe

Post by MediaMan » Fri 11 Feb , 2022 15:13 pm

Hi All
Please be gentle its my first time here, I have a Viceroy TDS Lathe, and i am replacing the variator that was fitted, but i have allways had a slight runout when turning a straight peice of metal, i have notice four large nuts above the motor holding the haed stock assy and presume these are for adjusting the head stock??, can any one give me advise on how to adjust run out.

Thanks

Roy

Sorry, what do you mean by 'runout'?. Its normally a phrase used to describe the amount a piece of work runs out of true when held in a 3 jaw chuck or collet. No 3 jaw is going to do much better than 0.003" runout, anything up to about 0.005" is generally held to be acceptable. If you need better than this, then use the 4 jaw. Headstock alignment has no effect on this problem at all.

If this isn't what you mean, do you mean that the lathe 'turns taper', in other words the diameter of the workpiece varies depending how far away from the chuck the tool is. If this is the case, theres lots of reasons why that happens. As far as I know, the 4 bolts you speak of are for bolting the headstock to the bed and can't be used for adjusting headstock alignment

Thanks for the advise, the bolts that i am refering to are not tight aginst the body, and seem to be some sort of adjustment nuts?,as the have secondary lock nut's but i understand that the runout when turning is fine useing your measurments.

Thanks
