Checking out the sine plate

211: Made a nut for it and found a clip that fits. But thread must be damaged..
210: Fine adjust
209: Class X
208: Art supplied this fine adjust - needs a 8-64 thread.
207: Missing parts nightmare.
206: Setting tail stock height.
205: Adjusting tilt with M2 test bar
204: indexing head disassembly to remove burrs and grit.
203: Indexing head
202: Chemistry table needed screw to make a stiff connection.

213: Turning the arbor for cutting splines
214: Cutting the key in the arbor
215: Finished arbor
216: Ready to make the spline shaft.
217: 4mm turned out to be too small.. a bit of warping
218: Welding setup
219: Using (miss using?) tread micrometer to get the depth right. Cut depth appears to be about 0.7mm.
220: Hobbing spline setup
221: Finished - there was porosity on the original metal side of the weld.. Hope it works.
222: aluminum tape on gauge block to lap 25-50mm micrometer - didn't work well..
