Newbie from Manchester (currently in hospital 😢)

I decided a few years ago to build a cnc machine, fixed gantry/moving bed, started off a4, resized to a3 on paper, built machine then increase size to 1200 x 450, all works well large and small, aluminium, plastic and wood, I want to improve machine x axis and make it look better than frankestiens daughter it currently is, she is made from aluminium 40x40 solid box and 60 x 10 flat bar, my first question is will aluminium extrution be as strong or should I stay with solid box/bar, could box section work instead of the sold 40 x 40.

Any help advice appriciated

No pic as I am currently typing this from my hospital bed

Hi and welcome to the forum its difficult for people to give advise on the information you have given. Can you put up some pics of what you have and a bit more detail of what you are trying to achieve.

I will be sorting a few pics of frankestiens daughter over next few days now I am out of hospital

good news,

Bright steel is what your looking at for straightness. This according to my welder friend.

Bright steel only means it has been polished. It has no bearing on any straightness or flatness. Your mate may have been referring to bight ground steel also known as drill blank. That comes in small packages and is expensive.

Well I'm not him, nor have I purchased what he suggested yet. He seems to think it's extruded. I may well have got the name wrong. That's just me. I've just used two equal angles from a wood burner as rails. Working fine.

hows you fella? where'd you get to in the end??

Bright Mild Steel has not been polished, it refers to mild steel in its bright drawn form which is significantly straighter and flatter than hot rolled mild steel.

Polished steel......lol

Loving that over a year later peeps finally come to my aid in debunking "Komatias" Polished steel statement.
Appreciated but moved on from then, lol.
