Installed bronze Skene chocks purchased at Anchor & Oars on 2024-09-19 using Frearson drive flat head silicon bronze #10 wood screws...what was available at the local stores.
Located the chocks as far back from the point of the stem and as far outboard along the edge of the stemhead fitting as possible. Location leaves about 1-3/4" between the forward inboard edge of the chock and the vertical center section of the stemhead. Drilled four 3/16" holes in the quarter-inch thick bronze stemhead to accomodate the unthreaded portion of the wood screw shanks. Divided the drilling into several parts in order to remove shavings, assess progress, add a bit of oil, and allow the drill bit and motor to cool. Bedded the ends of the chocks in white silicone sealant, a portion of which flowed up through the mounting hole and provided material to seal between the screw head and the chock.
