Fabricating things from metal, plastic, wood and who’s knows what else is pretty much what I do.
But before I agree to do anything, how about a few more details.
We know you want a 30″ long aluminum pole but of what diameter?
For that matter, do you want it to be round?
Tapered?
Hollow? Solid?
What alloy? (High strength aluminum alloys such as 2024 & 7075 cost more. 6061 is more common and pretty darn strong as well)
What is the function and purpose?
