Where to buy spindle

[HipoPapi]

Wouldn't it be better if you make the Z not only for that particular case but to be able to mount a normal tool on the spindle and to reach the bed or near it? I mean what if you decide to do something other than ice block?
Say you decide tomorrow to make a mold for the ice blocks, it must work as a normal machine not only with extra long bits, right?

I am intending to use a variety of cutters on the spindle not just this long one. I only have this one always in the spindle because this long bit and the ice block are the things that have defined the dimensions of the machine while designing it as my ice block is always the same size ( I mean this is the maximum size of an ice block that I use ) and the long bit is the one that needs to be able to travel on top of the block.
The Z is designed that the spindle can go down to 6 cm from the table. I dont think I will ever use any smaller ice than that and if I do I would still do the routing on the big block and then cut the finished slice of of it on the band saw because otherwise is way to fragile.
Using the machine for anything other than ice is probably out of the question as the machine will be permanently in a freezer and the freezer filters would get messed up. Also particles from other materials could contaminate the ice blocks in the freezer something I defiantly dont want as they have to be food grade.
I am planning to build a second machine primarily for wood if everything goes to plan with this one.

You have asked me earlier about the servos I am intending to use but than said nothing about them.....any thoughts?
