Then I glued all pieces together and cleaned up all excess glue



taped off speaker and port cutouts



started with cardboard templates for dented part, taped them off with aluminum foil and waxed. I temporary glued them in with hot glue 








 

prepared a few pieces of rowing 









template removed







added a 5-6 additional fiberglas layers from behind





the last thing I did was to smooth out transition between MDF ring and dent



....taday I started work on port endings and port pipe placement.....more pics later

....later sunday some new pics

I toyed with port ending/aeroport. Made 4,5,6 different versions, in the end I didn't even count them anymore. I made several attempts with Floral foam, one with modeling paste, ...and the last version was made out of filler with strands. Since I wanted to somehow keep rabbeted part of the port intact I hadn't many options to make desired flare shape, in the end I ended with just simple transition from port pipe to the rest of the panel. This part will be probably redesigned later. so heres some pics, not all versions were photographed, so here is what I have:
V1 with straight pipe, the exit of the port was too obstructed











V2 with angled pipe



Vx attempt with modeling paste - first step was to position port tube with 45 degree elbow











this is really tight fit...a millimeter on each side to the driver basket






then I taped off everything with Alu tape and apply modeling paste and shaped it to desired shape





again Alu foil and wax



fiberglas applied





after it cured I removed fiberglass part and cleaned up edges. I scraped it because there would be needed a lot of fitting and timing to get everything aligned perfectly....so up to a new version ....

more after commercials
