Hello from the Berlin Campground!
This year I'll try my hands on a class 2 build, but for now without welding.
This was my starting point today:

One (partial) break down and four cuts with the hacksaw later it's was mockup time. First I tried the 26' front. Looks good but learning from experience from my first SwingBike I need a steeper angle for the headtube. This either means cut and weld (no option so far) or drop the front.

So I tried the 20' front that was left from my trike build:

Much more to my liking...
Then I threw various parts at it and that's what stuck so far.

I will need a higher ape, but for now it's ok...
Now everything is tucked away in the trailer waiting for my next stay on the campground...

Nice work, I remember your post about building your camp, looking forward to seeing how your methods work on this build.
With "camp" you most probably refer to my shed build. That one is mostly done now and I really love to be there. This build here will move along the lines of my previous SwingBike build and only be continued when I'm able to spend some time on the campground in my caravan (that is stationed about a one hour cardrive from my home at the edge of Berlin).
So no daily updates to expect here, more likely every two or three weeks, when there is a long weekend.
 
Good brainstorming progress so far.
I like the vibe with the smaller wheel up front. It really gives the bike a more aggressive stance. It even somewhat looks like a donkey bike.
 
Made some good progress today:
I started by cleaning the Hercules part and scraping as much of the rotted gaffer tape as I could

Then I chopped the Mars frame parts and fork a bit more and made the wedge cuts for the bends

Bottle openers?

Ready for some bolting...

Next was joining the extra fork with the rear triangle.
First I fixed the fork in position with those metal hose clamps

then I checked the alignment

and drilled the holes for the bolts and secured it immediately after drilling of each hole

A bit later I had the wheels, saddle, stem and handlebar on and took it for a spin...

I quickly realized two things: 1: it swings much easier than my bigger bike but 2: the pedals scrape pretty often.
So I took the original Hercules fork with the small 20' wheel and tried that combo. It lifts the BB enough to slim down the chances of pedal scraping, but still keeps the easier swing.
So I threw some fenders at it

And this is how it sits for now...
I'll post a ride video when I'm back home, as the WiFi here on the campground sucks big time... 😠
