Need help with my G3-build

[JoFreak]

That's what I had in mind.
Maybe get one of the Lehner motor clamps and use that together with some shims.
But it seems Lehner decided to improve the website and erase all the dimensions from their motors...
There is not much I hate more on the internet then unnecessarry site relaunches that make everything worse

So right now I have no idea what clamp would fit the castle 1518, if any.
