Part six by Vince Cutajar

For the round profile to the sliding base I followed the instructions that came with the kit using the faceplate.  Located the part using a 6mm dowel.

And put some more clamps, just to be sure.
Nearly to the limit.  Initial used an HSS tool (because of the interrupted cut) and the lowest speed (160 RPM) but the tool bit was having a hard time and ended up just rubbing instead of cutting.  Eventually changed to the carbide insert tool.  What a difference and it did not break.
Then I did the 15 deg. chamfer.
The finish was not great so did an experiment.  Clamped the Dremel to the toolpost and using a grinding wheel ground the chamfered profile.  I turned the faceplate by hand during this process.  Much better now.
As I still had the faceplate installed and the top slide still set at 15 deg, I thought I would do another operation on the sliding tool holder base.  I need to mark three fiducial lines on the chamfered part.  These are at 10 deg., 0 deg. and -10 deg.  I used a different method than as described in the build instructions.  I got them marked out from the work table which has all the graduations.
Clamped it again to the faceplate and using a small HSS boring bar held in an unconventional way I engraved the three lines.  It was a bit of a tight squeeze but managed to do the three of them.
And this is how it looks.
Next, finished off the grinding wheel hub, delayed pending arrival of a long 5mm tap.  You can see the difference between the taps I had (left) with the longer taps (right).
To avoid getting the dividing head out I did some marking.
Then using a straight edge to set it up in the vice.
I had to reduce the length of the supplied grub screws and one of them was profiled to fit in the 4mm keyway on the electric motor shaft.
