After glassing ply core to outer skin do you do tabbing first or do you glass entire core first? What is the next step?

I usually cut the glass cloth large enough to cover the whole core with 6" of extra on each side and bottom so it will Tabb to the sides. It is much stronger as a continuous piece. Then I add extra tabbing over top of the wing tabs off of the larger full piece. Make sure you do fillets on the corners first before you add the cloth.

Now that it is finally warmer out I cleaned up the bottom of the sceptre and shot some more primer on it. I already had 3 coats of interlux 2001 epoxy barrier primer and went with a coat of white interlux epoxy prime coat over that. I will fix all the little spots and pin holes with an epoxy glazing putty and then it will be ready for polyurethane paint on hull bottom.

Sanded down with 320 and done another round of fairing. Removed the brass floor drains and ground around the hole 6" each way. Went fairly deep around the hole and tapered it back good. Cut a plug to back the glass. The wood block tying the deck to the hull on the drain was solid as the deck is. Laid several layers of glass starting small and working my way up till I had it a eighth above the hull. Will grind it flush tomorrow.

Got the deck drain sanded down and flushed with the hull.

Sanded the sides down with 320 and then added 2 coats of interlux Epoxy PrimeKote to the sides and one more over the bottom.

Finally got back on the boat again. Been working on my 71 Camaro instead of the boat but it is time to get her finished. I rolled it over to the opposite side so I could do the same as the other side. Sand sand and sanded. Got all the small blisters, nicks, scratches and bad spots filled then sanded. For some reason the back 2 feet or so of this side had some wave in the original gel coat layup and needed some line sanding to correct. I have a Hutchins hustler 2000 and use it on the course work but for this I bought a Hutchins 3800 orbital line sander for the finer grit paper and it gives me a much better finish product. I really love it, should of got it a long time ago. Similar to the standard line sander or flat board but it works like a DA sander in a orbital motion and leaves not scratches. It will leave a very flat surface and flatten out any high spots, waves ect. Sprayed epoxy primer, then sanded sprayed again then filled with epoxy filler then sanded, then primed again, then sanded then fixed any small spots left then primed once again. I will wet sand with 320 then spray white prime coat next. Nice to finally have the boat hull fully primed.
