My current thinking is to go for embedding mounting strips into the cast, similar to this French build - https://www.usinages.com/threads/fab...e-epoxy.15107/ as it will provide an excellent key into the EG.
And then I can machine them if needed, as the potential size means I should have the capacity to fit it in a mill.

I can understand the big benefit of doing it the way you did, is it means alignment should be far better, with no need for any major machining/scraping.

I'm dubious about the benefits of putting a complete frame inside a cast, as to me that has the potential to create some quite large stresses as temperature changes.


However I'd really like some real information about the various methods, as everything I found so far, seems to be done whatever way the builder thought was best.
