A very productive weekend...

Managed to accomplish a lot this weekend... Went for grocery shopping, took the kid to the park, had some nasi lemak, and, of course, worked on the hobby...

Finally got the time and peacefulness of mind to make the mount for the high speed water cooled spindle. Milled out of 0.5in 6061 aluminum, it worked like a charm. The riser was from the old proxxon riser, so I only had to make the horizontal piece. I also took the time to replace the water pump to a bigger unit with about 3m max head pressure... no problem so far...

Photo showing the spindle on the sherline... apart from the color, it is a nice match... no problem for the z-axis stepper to move it up and down...
The spindle bottom view. I mounted the magnets as per previous installment... tested and worked fine... may explore closed loop spindle speed control later...
The enclosure and the water cooling tank at the bottom... after about 2 hours of cutting with reasonable load, the water temperature rose about 5 deg celcius... nothing to worry about...
The first piece totally milled using the high speed spindle... from the center hole to the middle and end slots to the drilled holes... What is it... a new riser for the sherline to replace the old ones... so far so happy with the results...
