I am slowly getting some use out of my harrison, now that my car project is done I have a bit more time to tinker with the lathe I bought last year, which has been little more than an ornament since.
I used it with success as a horizontal pillar drill, but it would be nice to start using it as a lathe . To this end I'm working through all the niggles which at present prevent it from being an accurate and repeatable machine tool, most alarming of which at present; is the fact it doesn't run true.
Although its a situation full of unknowns (ie. is 3 jaw chuck true, is the harrison 140 faceplate true?) I'm confident in saying that the spindle nose itself is not rotating perfectly true. There is a sign of gaulling on the compound slide that looks like it has impacted the chuck in the dim and distant past, but it doesn't look like damage enough to account for a potentially bent spindle.
My lathe has the l00 spindle and the taper isn't exactly looking like brand new, there are a few dings here and there on it, and I'm hoping its the taper surface letting the side down rather than the whole spindle.
So to the point: Can anyone tell me how solid the L00 spindle is, has anyone seen similar down the years (I'm not a machinist and never have been) and how much work is involved in removing the spindle? If it is proven to be in need of remedial work then it'll have to be done.
Thanks
