Issue rotating kill brick

[Violet_sheer (TheOtherSider)]

1. What do you want to achieve?

I want to make a rotating kill brick.

2. What is the issue?

The issue is that at about, 90 degrees of rotating, my kill brick always gets stuck.

3. What solutions have you tried so far?
   I’ve tried tweening, using orientation/rotation, and looking at posts on how to rotate parts(various methods) but my killbrick has had a somewhat similar behavior.

Spinning Tween

spin = function(part)
	local info = TweenInfo.new(
		5,
		Enum.EasingStyle.Linear,
		Enum.EasingDirection.Out,
		-1,
		true,
		0
	)
	local tween = TS:Create(part,info,{Rotation = part.Rotation + Vector3.new(0,360,0)})
	tween:Play()
end,

Footage during tween:

Note: When I used orientation/rotation it just stopped at a number closed to 90 on the Y axis since I’m rotating on the Y axis.
Note 2: Actually when I use orientation the issue was the rotation on the Y axis was exponentially increasing.

Found solution, I used 2 runservices, and I have to use orientation with no runservice.
