Materials used in CNC build projects

Florin,why did you do that? ie quoted my text as if thats what I was actually saying.

I am sorry George, but it is quoted from your previous post (post #29)... maybe I misunderstood what you tried to say.

In my opinion, as a physicist, a good model replicates very well the reality, and this is the base of all human progress in the modern age. Instead of MAKING the mistakes, you can MODEL and avoid them. That's maths and physics good for.

If you can not model them yourself, you should trust the more experienced persons. Otherwise, you just waste time and money, but as Ross77 said, this can be educative.


All the best.

I've put the idea of using perspex to bed for the CNC build and opted for mild steel box section tubing, somewhere between 3mm and 4mm wall thickness.

Have purchased a mig welder,should arrive Monday? the thing that I now need t decide is to whether to have the gantry static or traverse?
Someone on here posted a link to a machine that was also done with box section mild steel and thats what swayed me to build it in this material,it wasso nice I wanted it. :)
Intentions of this build was to use as a router/carver and with future components changed for better quality this was the ideal material to use for heavyish work?

I won't be aquiring the box section for another week or so? but this will give me adequate time to get to know the Mig,had a go at arc welding in the past but that died a death due to me getting flashback at sometime during the usage of the arc welder,terrible thing to happen as its really very hurtful on the peepers for a day or two.

Fantastic George, steel is a much better way to go! Good luck in your project and keep us posted!
