Where to buy spindle

[HipoPapi]

Sorry got logged out earlier.

At one of the places I work at we have a 4.5 kw Perske spindle and it has been running for years now although it was used just for 2d work well time will tel.
But here is an example of something that would already make my happy and in fact it was done this way:

Here is the 3d model that I have made :



This is how it all fit into the blocks:


And basically I have only did two passes on each block like this:

Each of the passes went in 125 mm. The line across is for alignment basically just a scratch so I know how to align it with the next block.

And when the whole thing was assembled it was finished by hand.

Here is a video I have made earlier of how this works. This was for a pitch for a PlayStation game lunch:

So basically as you see it in the video the whole thing has to fit together as a puzzle and that is the most important for me the rest only needs roughing.

The antifreeze idea is interesting I will definitely look into that. Would that allow me to use the spindle a lot longer?


Any idea on what size ball-screws and steppers to use?

I am planing to use Hwin rails on each axes.

Thanks again for the suggestions finally I can fill this thing rolling :)

Erm your a talented Man and I would love to meet the Model riding that beast. . Lol

Don't worry about what ballscrews and motors yet because you have much more to do before you'll need to know that.? First you need a machine size/design and then choose material to build it from which will be needed to answer your ballscrew and motor question. When you have setteled on a size and design then you can choose the screws and motors to suit it.
Worst thing you can do is go buying blind before doing the home work. Just like you plan the Ice sculptures and they have a process how they go together in order building a CNC machine is same there's an order to build it in.? Starting with design again like your Sculpture's.!!
