MARK
V Tailstock and Toolrest
Carefully
remove your lathe center from the Mark V Tailstock. It’s a
simple fit – one taper slides into another, but it can get
awfully tight. Twist the lathe center out as if it was a dart.
If this doesn’t work, place the Tailstock on a work-bench
with the eccentric center supported and tap the lathe center
out with a soft-faced mallet. Whacking the center out, with
the Tailstock mounted on the Mark V, can loosen and damage
the Tailstock tubes and eccentric center.
Always
wipe the lathe center tapers free of sawdust and wood chips
before assembling the two pieces. A silver of wood caught
between the tapers can misalign the center or cause slipping
of or damage to the eccentric center.
Best
Dressed Tool Rest
It's easy to evaluate the fact that a properly prepared tool
rest plays an important role in obtaining a smooth, clean
cut as you make the final pass on a turning.
If you're
unable to glide your chisel smoothly across the length of
the tool rest without experiencing resistance, the tool rest
needs attention. Run your finger along the top surface. If
this test reveals any roughness or nicks, smooth the working
surface like this:
- Using
a mill file held lengthwise, file all nicks and rough spots.
Maintain the original profile of the tool rest or create
a new curved profile.
- Wrap
400-grit silicon carbide paper around a 4" log block of
wood and hone the metal.
- Follow
up with 600 grit paper to obtain a polished surface, then
apply a coat of furniture paste wax.
- Finally,
run the chisel across the tool rest and see what a difference
it makes to have a smooth work surface.
In order
to keep you lathe chisels from “dragging” across
the tool rest and producing nicks, file the sharp corners
off the top 25% of the end of the body of the chisel.
