I dont know what to do with the End pin

2 Options really

1.Scaffold - Clamp a bar to the back. Not easy on this design with the curved back. Youd have to make / source the clamp(s)
2.DB Endpin - Youd have to make a hole to house it. The curved back would restrict the depth of hole. How long would the endpin have to be? Would a DB endpin be long enough?

I used a steel bar which slots into a channel that I had prepared during assembly.

Good Luck
Theres nowt easy about EUB builds.
