I found Roland’s post from July in the files section. I am now converting it to a Wiki so that it can be easily found in the future. I will need a few minutes to complete this.

Rolando, I have been practicing in the past to do your routine for Polar alignment.  I cannot find the previous explanation you did I think this last summer.  Not used to the new format yet.  Can you point us to your previous post.  Tom

If you have an Astro-Physics mount why do you have to use any kind of aid to find the pole. It's so easy to use the power of the mount itself to align your mount. And it can be deadly accurate, more accurate than any kind of electronic polar routine. And you don't need to see the pole at all. Would you like me to explain this again how the mount can find the pole? It's super simple but may sound complex when it is in written form.

@Greg. Thanks for the tip about Cone Sharp. I was reading through the instructions and it sounded great, until I read the last bullet point about requiring "A decent view of the southern sky (due south), able to see stars with a declination of ~0”. Unfortunately, I do not have a clear view of the southern sky. I live in a sub-division and there is a house directly behind my observatory. The best I could probably do would be a declination of around 30 degrees above the horizon. I might still give it a try, but not sure if it will work.
