Adding a Spigot to my kettle

Any advice on where to place the spigot on my kettle? My plan is to flatten a small area on the side and install a weldless fitting. I've built the bulkhead adapter and only need to get a silicone washer for the seal.

How far up? Should I place the dip tube near the edge, or towards the center?

On a flat vessel I personally put the fitting as low as I can get. If using a pickup tube I put it on the side so I can stir and let the wort sit after I chill to form a nice clump of break/hops in the middle.

What about on a converted sanke? how far up should the bulkhead be located?

I used a weld-less fitting with an adapter to copper pipe on the inside with a copper elbow, non soldered, and placed it 1/8" off of the bottom and it siphons great. I did not have to flatten the kettle to get a good seal. Check the assembled fitting along the top of the kettle against the curve. The washers are pretty thick and will account for some curve. I measured 3 times and still had to psych my self up before I could bring myself to drill a hole in a one time used 60qt pot. Step drills are great for this.
