BUILDING THE WORDEN GRINDER

Part three by Vince Cutajar

Next: the cam collars. Marked the collars on the barstock and used a parting tool to mark the three of them. 

Drilled and bored so that it will slip on a 5/8" shaft.  Turned it to fit into the 22mm hole I did in the cam blank.

Did the other two and then brought the length of all three to the same size.  I left the length a little longer than the plans.  Should not make any difference.  Used the cam blank as a template for the 3mm tapped holes in the collar.
The three of them finished with a 5mm tapped hole on the side for a grub screw.
Next - some washers. Marked them, and drilled them.
These are going to take countersunk bolts.
Chamfered and parted them off. Also made a couple of plain washers of a different diameter. 
Another two knobs made.  These go on the ends of the same shaft that carries the cams for tilting the table.


This is the knob which should take the tilt graduations.

This is the other knob which locks the table. 
Both knobs finished.
In retrospect, if I had to redo these items again I would do them slightly different.  The large knob looks a bit too ‘chunky’, so it can afford to be a little smaller in diameter.  Also, I would not make the holes in both of them as through holes but blind holes.  I think they would look better.
