This has probably been covered countless times before but I am at the stage of converting my mast step to a series 2. I have the plans from admin and the only point I am wondering about is the new mast heel. I assume you have to buy the Selden adaptor along with the std tenon plug to fit to a Proctor mast?
I am also thinking that I might be able to get away with cutting a hole in the bulkhead that is the same size as the new wood being installed as there are two 6″ bungs on the bulkhead to at least allow at least some access. Perhaps someone has tried this way and that is why the plans suggest to cut a hole 160×150 mm.
