Hi Harry, I have decided against doing that taper idea I mentioned in an earlier post, I will now be using a far simpler method of construction.
I envisage that if I do the slices horizontally I could build each speaker with only one template. If you look at the option1.jpg in post #19
https://www.woodworkforums.com/f99/no...ml#post1444146 you will see that if I make the template the same as the top shape all I need to do is repeat the same shape about 8 or 9 times and glue them together.
For the top and bottom I just route the outside shape and not do the inside, giving me a solid lid.
I had seen those ones with the screw thread and figured they were for a different model since the Makita I have doesn't seem to have a screw fitting.
Thanks for the advice and I will avoid going that way if someone like yourself has safety issues with them.
I guess its not going to hurt to ask Makita how much they want for genuine ones.
