Evening All,
I have had the Chipmaster bed reground and now trying to work out total build up needed with Turcite to put apron back on correct plain with lead screw and rack.
I know what was removed grinding so that parts easy but have nothing decent to measure on the saddle.
Flat side of saddle has around 0.05mm so around 2 thou and that’s only on front edge. No surprise there as rear gibs were not fitted correctly at all was just lifting.
The V is my issue as the wear line is very deep and almost right on bottom of V.
Its too thin to get depth mic reliably seated and parallel.
The only way I can think is to clock in V flat on surface plate by propping saddle at 45 degrees. Then measure step at bottom of V.
Any ideas appreciated on this.
I would use rack engagement as good rough starting point but the pinion is pretty sharp.
Also leadscrew bush in gearbox is pretty worn so not sure that’s good guide either.
