welding steel base or just getting aluminium extrusion

[reefy86]

I'm going to go down the aluminium extrusion route after all and for a few reasons, the obvious one is i aint welding all that steel and i defiantly haven't got the funds to pay someone that amount as well as having the funds to pay 3 months upfront deposit on a new workshop unit and then the frame on top lol. I know its worth the price what the guy offered but i just can't afford it on top of everything else.

Now there is 2 options and option 2 does have diagonal support i just couldn't be bothered to add them in lol

option 1

copy the cnc pro kit 4896 from cncrouter.com (frame bed only) costing me just under £1k which is using the 40x80 profiles but the heavier ones

option 2

80x120 with less profiles then the 40x80 costing just over £1k but these are the light profiles not the heavy ones

i know its way more expensive then steel but i am not as lucky as most of you with welding skills and i can always add to the frame once more funds come in. personally i prefer option 2 as it looks way more solid but would like your opinion and if and where i should add extra support.

Appreciate the help guy's
