Oh you are going to love this. :lol: to recap, cutting a taper, toolpost in usual position, large end of taper at chuck end, cutting right to left. as you know, I stripped and refitted the top slide. tried just now with a new piece of steel. same thing, cutting barrel shaped. :doh: then I tried something silly. I moved the topslide assembly to the rear of the cross slide, put a different tool in, swung the topslide round a few degrees , ran the lathe in reverse and cut on the back of the taper. and it cut a WASP WAISTED taper :doh: :doh: :doh: so I've got a topslide that likes to turn right. (sounds like a Dr Who story). at least it'll fit without a wobble :D if the tool was being pushed away from the cut as the topslide extended you would think the cut would be the same no matter what side it was cutting. I don't think I want to turn anymore tapers. :( :( cheers A thoroughly confused Roy |

Roy, Thanks for letting us all know. Quite a clever way you sorted it out :thumbup: I would tend to agree with you, nothing is pushing, I think it must be your top slide, or at least the dovetails. I’m glad you have at least a morse taper you can use. :) :beer: DaveH |
| John Hill:
So Roy, does this indicates the top slid dovetails are not straight? |
| wheeltapper:
Haha, as far as I can see they describe a very large circle. :lol: what I might do is strip the thing down (again) clamp the slide part onto the mill table and run a D.I. along the dovetails to see if they are straight. I haven't got as far as working out what to do if they aren't. :bang: :bang: if I do this I'll let you know the result. Roy |
