I picked up a compound slide for the little C1 lathe to enable me to turn tapers last week but I've come across a weird problem when using it. When I turn a taper the surface of the taper has a furrow like finish? It is not the wavy finish you sometimes see from judder but more like the cutter is being drawn into the work and then deflected as the hand wheel is rotated. I've tried adjusting the gibs to take out the play but that didn't help, in fact it made things worse?

Any ideas guys?

I tried tightening the gibs that didn't make any difference, Ill try the other suggestions see what happens.

Just finished stripping the compound slide. There was a lot of old dried up grease on the slides so I cleaned all that off and like Hopper said the gib strip was quite poorly finished with lots of small burrs so I gave each side a rub on the wet stone to smooth it out. Reassembled with a dab of oil and it seems to have done the trick!

Thanks guys.
