How can I make a rotating block that the player sticks to?

I'm trying to make a block rotate and have any player standing on it move with the rotation of the block but no matter how I go about coding it, the block just rotates without also moving the players standing on it.

Here is the code using CFrame:

while true do
	script.Parent.CFrame = script.Parent.CFrame * CFrame.fromEulerAnglesXYZ(.002,.005,.009)
	wait(.001)
end

Here is the code using Vector3:

platform = script.Parent
a = 0
b = 0
c = 0

while true do
	platform.Rotation = Vector3.new(a, b, c)
	wait(0.01)
	a = a + 0.1
	b = b + 0.2
	c = c + 0.15
end

Any suggestions on how I can make the player rotate with the platform?

Possibility 1: Using lookVectors

My first suggestion is to use lookVectors to push the player along the face they are standing on.

local player = game.Players.LocalPlayer
local part = workspace.Part

part.Touched:Connect(function()
	player.Character:SetPrimaryPartCFrame(player.Character.HumanoidRootPart.CFrame + (part.CFrame.LookVector * Vector3.new(0.05, 0, 0)))
end)

while true do
	part.CFrame = part.CFrame * CFrame.fromEulerAnglesXYZ(.002,.005,.009)
	wait(.001)
end

Possibility 2: Using Welds

My second thought is to try Welds, which will guarantee the player is moving with the part's rotation, but must be broken / removed by another function (as the player wlll be unable to move)

local player = game.Players.LocalPlayer
local part = workspace.Part

part.Touched:Connect(function()
	local weld = Instance.new("Weld", player.Character.HumanoidRootPart)
	weld.Part0 = player.Character.HumanoidRootPart
	weld.Part1 = part
	weld.C0 = CFrame.new(0, -5, 0)
end)

while true do
	part.CFrame = part.CFrame * CFrame.fromEulerAnglesXYZ(.002,.005,.009)
	wait(.001)
end

I'll be happy to answer any questions or concerns regarding these methods.

EDIT: Comment, to call the player in the server, you need to activate a touch-based detectable event (usu. w/ ClickDetectors or .Touched)

Server Variant of lookVector

local part = script.Parent

part.Touched:Connect(function(hit)
	if hit.Parent:FindFirstChild("Humanoid") ~= nil then
		local character = hit.Parent
		character:SetPrimaryPartCFrame(character.HumanoidRootPart.CFrame + (part.CFrame.LookVector * Vector3.new(0.05, 0, 0)))
	end
end)

while true do
	part.CFrame = part.CFrame * CFrame.fromEulerAnglesXYZ(.002,.005,.009)
	wait(.001)
end

However, since this doesn't work as smoothly as the Local Variant I suggest using the first code listed above instead (placed in a LocalScript under StarterGui)
