Great work. Try making a Flexible Shape Pattern Template, as Wray Schelin always depends upon to match the fit from the Buck, and also his Shrinking Disc would be fantsatic for this application!
Thanks Rachael! The sanding is actually only so that I can get a reference that everything is even. I will still have to do a lot of planishing to get it smooth"ish". But I'm definitely going to be using some filler... But only a little bit 😉
