Don't think I have any concerns as of now. I do have a Dremmel and has been very handy over the years. Do you have any recommendations as to what to use as a release agent? I think I know what you mean by mechanical locking points. By that do you mean ways for the epoxy to hold better or "lock" onto/into its surrounding material....if that made it clear...lol
As reference the videos I watched were on youtube done by "wildernesseducation". Hes a Scottish lad.
