BUILDING THE WORDEN GRINDER

Part two by Vince Cutajar

The table stops are nothing special. I just had to be careful when boring that the stop would be a sliding fit on the ground shaft. So started by cutting a piece for both stops from the 1" material supplied.  Faced both ends and drilled and bored the hole so that it would slide without any wobble on the 3/4" ground shaft that was also supplied.

Took a while and a lot of patience to get the hole bored to the correct size.  I then parted off in the middle and cleaned it up.
Drilled and tapped for 5mm.
Then made the brass screws.
To make the cam blanks I decided not to follow the instructions here as I thought using a different method would be easier for me. 
I had to make a jig to hold all three blanks together. 
I was lucky to have a 65mm aluminium off-cut for the jig.  First job was to clean it up.
The centre was marked while still in the lathe.  It was then transferred to the milling machine where two 3mm tapped holes where made.  Although on the plans the holes are shown as 2" apart, in fact, I found that they are actually 50mm apart.

The three blanks were bolted to the jig and the offset hole and centre were marked.

Back to the lathe and the diameter of the blanks reduced to 2.75".
Back to the mill again to drill and bore the offset hole.
Two 3mm through holes were also drilled to the side of this hole.
I was not planning of doing the following, but when I arrived to this stage I changed my mind.  Although not required, the cams can be cut to provide clearance for an optional Feedscrew Traverse Kit. I do not know if I will be doing that but I thought that as everything is set up, might as well do it.  So the line of the cut was marked off.
Using the angled point of a scriber, the jig with the blanks was aligned on the mill.  Most probably I could have eyeballed it also.
Used a slitting saw to do the cut.
Blanks finished and cleaned up.
