Got the CP's all constructed, still need to run the router over all the edges but pretty close. One thing, been a bit stumped

on how to roll the front edge over on the CP, due to the sloping angle of the top surface I cant get any bite with a router bit, think the only way will be to do it by hand and eye?
It appears as if your CP's are removeable. If you have access to a router table, remove the fence on the router table (if it's got one) and use whatever profile bit you want. I'd almost suggest a chamfer bit and a scraper/hand plane.
Other than that, hand sanding is gonna be the fix. Get some solid insulation (perhaps you call it styrene....the pink stuff that's thick and stands up on its own) and machine the profile you want. Stick some sandpaper on that, and sand away. That'll keep the profile standard-ish all the way across.
