I'm trying to make it look like your arm is stretching, the problem though is that the tween will scale quicker before the c1 gets a chance. Is there a way to be able to sync the tween and the c1? Please help!!!

Here's a video of the problem: https://streamable.com/jg5xsq

Server Script

for i = 1, 24 do
	wait(0.033)
	if i == 1 then
		gomuTween:Play()
	end
	gomuWeld.C1 = gomuWeld.C1 * CFrame.new(-0.3, 0, -0.07)
end
