Switch that when it is touched it rotates more than one brick on the same pivot?

local part = workspace:WaitForChild("Test3"):WaitForChild("Move3")

script.Parent.Touched:connect(function(hit)
	if hit.Parent:FindFirstChild("Humanoid") then
		
		part.CFrame = part.CFrame * CFrame.Angles(0,0,math.pi/14)
		wait (1)
		part.CFrame = part.CFrame * CFrame.Angles(0,0,math.pi/-14) 
	end
end)

This is so far what I have done, I do not know what I could do to make more than one brick rotate together on the same pivot.
