I actually used a suntour router deal for the over the bottom bracket area and it is all sorted out. The only issue I have now is that my suntour derailleur that has a cable stop can't shift all the way out to the big ring, which isn't a huge deal since the cassette goes down to 11t

That might work really well with shellac? Never shellaced before though.

This looks like it would do the job, might have to order one for the sake of the bike not looking like a hack job
