where to buy aluminum extrusion

[troyboy1]

Have you considered using steel box section instead of aluminium extrusion? It's much cheaper. Can cause problems with resonance, but there's ways round that.

tanks a lot Jonathan,for your reply . i went to the web page, that you mentioned,and there prices do seem fair. have you used this material yourself ? and can you explain what you mean , that you can have problems with resonance ? and how do you get around this problem ? as i say , i am a complete novice to all things CNC . i am trying to learn as much as possible ,before i start building this machine. it seems like a daunting task, to a novice. have you built your own CNC MACHINE, if i need any more help and advice , can i keep in touch with you.

yours kindly paul

Hi Paul

I bought my extrusion from here and got lots of advice from Philip Lambert. The extrusions are super quality and the heavy gauge 80x40 sections (4kg/m) are really strong!
