Was time to replace canvas and after looking at the cost and longevity (and since I have experience with fiberglass) decided to build a custom mold and hardtops for my 380. The hardtop extends about 48" forward from the radar arch and has the appropriate curves and changes in shape to accommodate the fit. I will be using the same mold to pull off another one to modify for a 3/4 rear top. I will be making some custom SS or Aluminum support legs once I fit it. Top will attach to radar arch with male to female fiberglass tabs set in 5200. Top is made from the appropriate gelcoat, CSM and 1708 BiAx followed by 1/2" Balsa and then CSM and 1708 Biax. There will be no penetrations in the top so I am not worried about Balsa Core issues. The underside of the hardtop has built in "shelves" to screw in the track for the windows/curtains. The mold is not a "Class A" mold, meaning that some final fairing and tweaking is required but since I will be painting it anyways its not an issue. If anyone is interested, I may be willing to sell the mold for the cost of the material to make the mold...... Today is pull the part out of the mold day!
