Using a 4-foot ruler as a straight edge, I drew reference lines on the plywood to show placement of the floor battens. That made it much easier to mark the places to drill holes & drive screws. Marking the chines for screw placement has not been so easy. I’ve had to cut away enough overhanging material so that I can use my marking gauge — the same spring clip & duct tape arrangement I used on the side planking. I used the Porter Cable multi-tool saw to cut away plywood as I worked my way forward... cutting new plywood washers as I went.
|Bottom panel, before much extraneous material was removed.|
|Looking forward, you can see the panel begin to curve and twist.|
|Reference lines for the battens helped greatly with screw placement.|
|Here, a good bit of material has been removed from the panel. It became much easier to bend.|
For now, my progress has stopped at the forward frame. I’m just inches away from the transition joint. To mark the approximate cut line up forward, I coated the corner of the side planking with a lumber crayon & bumped the bottom planking panel against it to transfer the mark. It worked reasonably well. Soon, I’ll remove the bottom panel, cut near this line, and re-attach the panel for further fitting.
|The transferred line on the inside of the panel should help greatly when I remove the panel & trim it down further.|
