I've added a speed/frequency table for the new CNC machine to jesref: https://incoherency.co.uk/jesref/speed-freq.html

And printed it out to stick next to the VFD.

Plan tomorrow is to drill the table and glue in some threaded inserts.

I think:

• use CNC to drill the table
• unbolt table from machine
• clamp table to aluminium surface
• transfer hole locations
• drill mounting holes in aluminium surface (don't go too far over-size, try to be accurate, can always widen them later)
• epoxy inserts into table

And then I can sort out cable management in the tub. And perhaps think about how to attach the flood coolant nozzle.

And, next time, after the epoxy is cured, I can bolt the table back on, pick up the hole positions, and:

• bolt the aluminium surface down with only 4 of the 5 bolts at a time
• machine the counterbore for the head for the bolt that is not installed
• repeat for each of the 5 bolts
• drill the grid pattern of holes
• take the surface off, tap the holes, bolt it back on

So tomorrow is:

• make progress on the CNC machine, as above
• make some progress on the CAD model of the house
• make some progress on the balance wheel for the clock if there's time
