Did some engineering and made additional sideplates from a 3 mm aluminium plate. Made 4 pcs M3 holes. Cleaned the surfaces well removing also the black paint. Glued the sideplates on with extra strong two-component Araldite and added the M3 screws.|
Sealed the gap between the body parts with a layer of the glue. Finally added a 1,5 mm aluminium plate under the wifi and bluetooth antennas, because there was a piece missing.
When everything had dried, I reassembled the Ronin M, attached a charged battery, turned it on and...
So; electronics seems to be working and the vertical body is now more rigid than the original part.
Cost: 10€ for the aluminium plate (had to buy 1m long 3 x 40 mm bar) and about 5 hours of dismantling, planning, cutting, sawing, drilling, filing, gluing fitting and assembling.
