Thor, or should that be Zeus?

Looking very very good ;) I just love CNC machined aluminum it's like a work of art all on it's own!

I hadn't appreciated how big your ballscrews were lol! How big are your rails? I'm guessing 35mm+

My rails are 40 and if I recall 35 for the smaller ones.

The ballscrews are 40 and 25 from memory.

LOL you beat me to it I meant to write 35mm by the time I edited it you already posted lol, looking at the pic of your hand against them damn they're big.

If you don't mind me asking how much were the ballscrews and rails? I assume they're not cheap lol.

I need to check, I bought two sets of components from my supplier, I think all in for 4 x 1180mm 45 Bosch rails plus carts plus around 6 different ballscrews (longer length) and 2 shorter length ones plus the a short set of rails and the Rosa ones being used on my Z Axis (700mm) was around €2500 or 3000. Not cheap but the 'list' price on a Bosch 45 Rexroth with rollerbearings and a set of carts is around €1K per set.

That seems reasonable I was thinking it would be even more! Amazing how being into cnc changes your perspective of reasonable lol.

So glad I only want to do aluminium and wood. This is definitely the most interesting (Read loony toons) cnc build I've ever seen if only for it's grandeur.

Ye, its all relative. Let's see if this thing even works or not .... I should know in the next few weekends.

Ok, cleaned up a bit, removed the reference table, mounted the main table and did a quick test fit of the Z Axis bottom part.

The naked machine

Some bits on it

Z axis, ballscrew is just 'hanging' onto the overhang, not mounted. The Z axis needs some of the holes to be drilled all the way through and I need to find the location of the bottom carts. I did not have the measurement at hand when I machined the holes on the larger mill. As these are not threaded, I have a bit of margin for error.
