Progress is going slow, not only did I solder the ground cables wrong. I also soldered a lot of diodes in the wrong direction. I soldered the first one wrong and used that for reference for the next etc...
But on the plus side; I'm halfway done with the soldering of diodes now!
The gate and ball lock is taking shape as well, need to rearrange a ball guide and drill a few holes but other than that it shouldn't be much more work.
Sadly, I'm starting to toy with the idea of a kickback in the left lane too, haha. But I guess that'll have to wait. :)
