LOL thankyou for the warning but im not that heath... I have a motorcycle scissor lift with digital weight guage on it and that can go beyond 1.5 tone, so we should be ok there and i will be building my Z when i know what forces i will require it to achieve.

Ahhh now there is a question..lol, I will not be able to answer that until i have my Spindle and Motor. So for now i am working on reducing any twist or flex on the gantry itself.
