I finally found the time last week-end to assemble my CoG Machine, made from 2 kitchen scales, some aluminium and 3D printed parts. The 2 scales are glued on a wood place using some cartridge sealant. Prior to that, I did a trapdoor below to access the batteries. The 3D printed support is also sealed on the scale plates so everything is fixed together.
The advantage of this method compared to the usual CG balance is the repeatability of the measure.
I know that, since my first post on Facebook, some CoG machines are in construction here and there ;) ! This is good to know !
