Lathe stops when it's not supposed to
Dear all,
I have the Hare and Forbes 900 b/w centres woodlathe. One very annoying feature about it is that when spindle turning it stops when you apply any sort of pressure onto it with a woodturning tool. Increasing the speed helps for a while but then it still stops unless I use reduced pressure and even then it will stop sometimes. I am sure there's an easy fix but what is it? Tailstock is done up as tight as it will go. The tailstock centre is also done up tight.
