For the mid size speakers I made little round over blocks since they can be seen from the inside of the center console.
The blue block picture is of the anchor box. I am adding a red bungee cord to keep it in place, specifically thinking through the hooks the cord will have and where the cord will attach. Thinking through stuff like this is really a lot of fun, how each detail works out in the end.
The blind nuts have been epoxied into place. They are for the battery hold downs. I pulled them down tight with large washers and the boltsI plan to use on the batteries.
The pic of the fillet is on the panel that hides the fuel tank. It is more to make things easy to clean up than anything else.
And Dougster - found one of the flexi things at Rockler, made by Makita. Looks to very similar so I took a pic for you.
And then one picture of what I think is the last board I will purchase for the boat, some dimensional mahogany, along with a cool picture I received from a client.
