First of all I'd like everyone that read is reading this to post their opinion on this:
Is it important for you that the block is polished (looks like a mirror) on the sides or will you be satisfied if it's not polished but it's really smooth as in you can't see a single scratch from the machining (a very very thin sandpaper would be used)?
Please give your opinion as this is very important.
Good news are I got myself a belt sander, that should help the machining process _a lot_.
Here are some work in progress pics:
Before you ask about the top thickness, it's 6mm, I know thats too thick (it will be 4mm in the final relase) but it was the only kind of copper bar I could get without having to order tons of it. Anyway it's not that heavy. Well here they are:
They look "brownish" and uneven because I work with water most of the time to cool them down while they're being machined so they are a little oxidized, of course that's not how they going to be (a thin sandpaper and they're new). They are already very flat and quite smooth, they will be even more as they're not finished yet. You can't see much detail in one of the pics so I also took a close up pic of one of those blocks, this is how they look so far.
