Two centres are supplied with the lathe both solid (6), the MT4 centre weighs about ½kg. A better solution will be to manufacture a new clamp and suitable cam lever mechanism. I have improved things slightly by fitting a spring between the clamp and the underside of the saddle (5) and filing the sharp edges off the clamp casting. Locking the tailstock is also hampered when close to the saddle as the spanner hits the top-slide. This means that the clamp nut must be left at least a full turn loose which in turn makes clamping up a bit of a chore. The clamp bracket under the bed is a very loose fit (5) and consequently can swing and dig in when sliding the tailstock. This is probably one of the most unsatisfactory parts of the WM 250′s design. The tailstock is clamped to the bed by tightening a nut with a spanner.
