Columbia 28 Mast step rebuild
 
Thought I should post this over here for anyone that runs into an issue with their mast step.

Here is the old aluminum mast step next to the new mast step. I made it out of a vinylester based GRP board along with a layup I made with 1708 and vinylester. The bottom piece is exposed to sunlight and is gelcoated later.

Here is the new fiberglass plate and studs in the cabin top getting epoxied in place. I chopped back to clean wood all around. Columbia actually ran the wires in the layup between the cabin top and the liner. I will exit the wires on the side of the mast in the future.

Laying up fiberglass. Used 1708 here.

Mast step and organizer plate test fit. Anyone see a problem here? Stupidity is the mother of invention. That sweet hammer, that came with the boat, make a great stud adjuster

Fill and sand. Fill and sand. Studs are sharp and sanding around them sucks. Nothing sticks to soda straws

Getting dark. Sorry camera overexposed with the flash. Needed to use a heater to beat the sunset and getting the gelcoat to dry. I had the gelcoat really well matched but hadn't mixed enough. I added too much white the second time around. Hopefully as it oxides, it'll darken a bit. If not, I'm probably the only one that will notice it.

Sand, sand, sand. Old gelcoat is really hard which is nice for sanding the new. Did I mention sanding around the studs really sucks? If I didn't, it does. Donated some blood to the boat.

Corrected my stupidity. Installed and ready to go.
