Has anyone tried out this project, a single-shot 22 RF?

Lots of folks recreating older rifles. DeHaas has some great plans.

If you want a simple rimfire, look to Browning's patent #511,677. .22 rimfire with 2 moving parts and one of those is the spring.

Interesting. The breechblock aspect leaves me puzzled, but I haven't studied the patent long enough to understand all of it (I can be kind of simple sometimes).

Basically, the trigger, hammer and breach block are all one in the same. Pulling the trigger releases the breach block with the fixed firing pin to pop up at an angle. At the top I f the travel the firing pin indents the rim and fires the cartridge.

The hammer rides at a steep enough angle to be a sticking taper, then, and isn't driven back down the spring channel when the cartridge is fired?

Correct. The moment of force generated by the fired cartridge is directly in line with the bore. It pushes against the mechanism as if it were a lever but there is no way for it to rotate.

You got it!

Now I have a picture in my head and have to see if I'm right.

I would love to see a sketch or a good picture of the hammer.
I can not wrap my brain around the location of the pivot point vs the force vector from the cartridge.
