I did raise this on the old forum but have some further questions (and the post didn't make the cut for the archive). Thanks to those that contributed earlier.
After my block destruction I'm aiming to put at the very least an extra block stud at the rear. The engine is a 1928 magneto crankcase.
The idea is to tap a thread into the crankcase through to the rear cam bearing. The space to fit the stud between the rear of the block and the starter motor casting is really quite narrow.
My question is whether it's better to use a long stud bracketed from the head (as Pigsty do in this illustration ) or use another route.

The alternative route is to bolt a bracket to the bottom of the block and clamp that down to the crankcase.
Part of me is attracted the "clamp" approach of the bracket technique but the long stud from the head has a simplicity about it and it avoids tapping into the block (I'm quite keen to avoid any risk of weakening the block).
Does anyone have firm opinions either way?
Also in a magneto engine replicating this approach at the front is very hard if you want to run a dynamo. Any creative approaches welcomed.
Thanks
Charles
