How to weld multiple parts as a tool?

local prev local parts = script.Parent:getChildren() for i = 1,#parts do if (parts[i].className == "Part") local Weld = Instance.new("Weld") weld.part0 = prev weld.Part1 = parets[i] weld.Parent = prev end prev = parts[i] )end end

I'm able to weld a part to my hands it horizontal but, not vertical how do I weld multiple parts and fix this?
