Cabinet looks good, not so keen on the control panel but that is just personal taste, the actual build looks great.

I love the wiring process myself, one thing though, curious about the earth wires, why not use Din rail connectors?

Hood

Two reasons,,,

I have done it that way before,
Did not have any more terminals

However, i have just found a source of terminals in a machine at work that is no longer used, i have a feeling it will be a bit lighter before today is out

I agree, it would look a lot better and make use of that dead space.

Old machines, best place for parts and you are recycling into the bargain

Ok, salvaged a bunch of din rail terminals, not proper grounding ones but will work nicely, looks a bit tidier too.

Ok, so its been a quiet day in the day-job today but couldn't sneak home to work on the project as it was my watch as they say

Been playing with Fusion360 Sort of come up with a plan for the top plate of my dual-spindle adaptor for the mill. My thoughts are in the machining process...

Steps...
Spot the three holes in the middle,
Drill them through,
Counter-bore them,
Rough pocket out the two big holes,
Finish pass on them,

Questions so far,

should i rough the holes then finish with a mill tool or should I go for the boring head and bore-gauges/caliper ??
I was thinking to then flip over in the vise, mill the slot on the rear face, then flip back, bolt to table on scrap pads through the big holes and do the outer contour followed by the two small slots and a chamfer pass?
How to chamfer the rear face once contoured?

So far its been a blast, love the 360deg view

Not sure of the setup of your aux spindle but would it not be possible to have an R8 on that plate so that it could fit into the spindle and save a bit of travel? You would need a rod on the plate going through a bush on the side of the head to stop it rotating but should be simple enough.

Already there hood, here is a design i'm modifying / copying (pic below)

Its a H shape and my version will have a 20mm spigot that goes into an R8 collet in the spindle.

This part is only the top plate of the H, one plate would not be stable enough i think.

Think it could be made stable just by having a guide rod or possibly two from the top plate and have guide bushing on the side of the head.
You could even use the guide rods to hold the two plates apart  instead of the  upright plate in your pic.
Now whether it would be worth it for the small gain in travel I don't know.

Hood

Thats the thing, i'm only looking at losing about 20mm on Z so will still have 100mm + to play with - thats more than I have on the mini-mill so should be ok, the tools are all small apart from the Haimer - will have to move the table out the way to get that in i think. I can now see the advantages of a large Z travel, but sadly will never have it on this build.

Wiring the pendant up today, panel is finished, nearly testing time.
