Hi Jeff,
I do have the exact same camera so here goes.
Right in front of the cone there is a plain ring just behind the fine saw tooth ring, this ring has a couple of small screws. You loosen these and then turn the whole front CCW until you start to get your image in focus.
I measuered an object about 5 meter from the lens, set the focus ring to 5m and then adjusted the whole front assembly til it was in focus. Then turned back the saw tooth ring to be snug with the cone and tightened then two small screws again.

It does take a few tries and you will eventually have to rotate your lens so you can see your aperture and shutter settings but once done it works pretty well.
Please let me know if you need more details or if i forgot to mention something.
