Thread: This is what happens when things aren't held down properly

Dont forget Elan, CNC makes life easier and stress free. I bet it doesnt seem like it

As long as I'm not the one who breaks it I don't mind so much, I quite like pulling things apart

but why?


I am being serious. Why use the CNC where the vacuum will presumably pull some of any bow / twist out of a stick rather than the conventional tools?

The vacuum does nothing if there's even the slightest bit of space, I'm not sure if you've ever tried to flex a piece of timber of that section but it isn't going anywhere in a hurry.
We ended up screwing two boards to the timber so the vacuum had something to hold

I understand that a board that thick is not very flexible, but I remain curious about the relative speed and waste of flattening and dimensioning on the CNC vs using a jointer and thicknesser

The main advantage is not having to manually handle 40+kg boards. We only did one face on the CNC, then thicknesser, then an edge on the panel saw, then thicknesser to width. The finished thickness was 62mm, so the waste was going to happen anyway

Out of interest, what are you making that needs a board 170(?) x 62, 3.2 m long

A 3000x1200x60mm dining table

I know someone in Melbourne who can sell you a small crane to move that monster into place

Fortunately we didn't deliver it, but it wasn't too bad with one of us on each corner
