How does the chuck maintain it's tightness to the tenon?

The chuck tightens like the Grizzly and Penn state chucks as well as some of the older nova chucks. The back ring turns like a big chuck key and is tightened with torsion bars (orange handled bars seen in picture) inserted into the holes positioned around the chuck body and back ring

Will this work on a psi penpal lathe?

I don't know the tpi for your lathe. However, you should be able to get an inexpensive thread adapter here if you need one. I needed one for my harbor freight lathe. The combination has worked great!!

I have a "harbor freight" - lathe - model # 65345 8 x 10" 5 speed 1/2hp .. will this chuck fit my lathe? i believe it's 1" x 8 thread.

If it is 1” 8 TPI it will fit. Please double check the specs at Harbor Freight. I’m not sure if the small lathe is 1” 8 TPI.

How do i attach this to my harbor freight lathe? the spindle that came with the lathe is not threaded and i cannot find one online.

If your spindle has a face plate, you'll have to remove it first to access the spindle threads. Both wood turning lathes currently offered by HF have threaded spindle headstocks and MT2 tailstocks. Can't speak for older HF models, though, but lathes typically come with threaded spindles.
