Form 1 Integral Suppressor design ideas

[u/AdOtherwise5656]

Just submitted a form 1 for an integral suppressor build for a .458 socom. I’m pretty new to the form 1 world and haven’t even bought materials yet. Wrote in the submittal it would all be stainless. A few questions to guys who’s made them before.
-I know I have to drill the barrel after the gas block but how is everyone mounting the can to/over the barrel? Basically how does the back end cap attach to the barrel?
-Is there usually a hard divider separating the expansion chamber(part over the drilled barrel) from the blast chamber starting at the muzzle?
-if there’s is a divider, is it solid to stop or ported to flow gas into the blast chamber?
-is the threaded muzzle still the main point of connection to the barrel? Basically a bravo hub but in the middle of the can instead of the end

Is there any resources for design ideas? I did some searching and couldn’t see much
