I managed to finish all 16 inserts, so another job done:


All the Y and Z axis material has arrived from aluminium warehouse. All fine except they sent me 5" round instead of 5" square. This is to make the block which holds the spindle. Quick phone call and they sent me the 5" square for free and told me to keep the round:


So onto the Y axis sides. Here is the CAM:


Laying out the blank:


Holes:


Profiled:


Holes tapped:


Then the corners had to be filed square to take the stepper bracket:


Edge holes drilled and tapped:


The second one was made the same way but snapped a cutter with the adaptive being effectively too aggressive. Actually it was my fault as I did not align the blank quite right and so the cut was too wide as the stock was not where the software thought it was. Anyway, we got there.

Couldn't resist a dry assembly to check it all fits:



There will be a piece of bent sheet over the front and rear, so checking this will fit flush to the stepper bracket:


Then onto the Z axis. Here are the raw stock parts:


Top plate being set up:



All for now.
