After machining the gibs
and the holders on the taper jig I discovered that the blocks weren't truly
parallel and that the gib stood up a couple of thou higher at one end. In the
end I superglued the gib to the holder and machined both flat together. That
got the tapers spot on.
Once the gibs were offered
up I noticed that the shoulder on the near side was hitting the crank rack.
Tricky, the lathe was in bits and I couldn't turn them down so I stuck the rotary
table on the mill, whacked a Sherline chuck on to it and then used an end mill
to shave the shoulder down till it cleared the rack. All told, I'm very happy
with this mod.
