How do I make a HingeConstraint point to the mouse?

I'm not very good at CFrame but I'm trying to get it so a HingeConstraint will point to the mouse.

local Players = game:GetService("Players")
local Player = Players.LocalPlayer
local Mouse = Player:GetMouse()

local Part = workspace:WaitForChild("Part")
local Controller = workspace:WaitForChild("Controller")
local Base = workspace:WaitForChild("Base")

while wait() do
    local NewCFrame = CFrame.new(Base.CFrame.p, Mouse.Hit.p):toAxisAngle().Y
    Controller.Horizontal.TargetAngle = NewCFrame * 20
end
