The name is subject to change but it is started. I did some more design work today and ripped some lumber. I was given some cull lumber that had been in a barn for 20+ years. The red oak showed signs of powder post beetle activity and th3 sycamore was pretty twisted as it is prone to do especially since it was plain sawed. I took maybe half of the sycamore that wasn’t terrible and a little bit of quarter saw red oak with minimal bug holes, I hope I don’t regret it. Anyway the baffle glue up is for two speakers minus the legs which will be glued on later, before planing and sanding. 19.25 will go through.
It is a quarter inch thicker than I need right now. I expect it to move some over a few months in a dry environment. I intend to then take out any twist and then run it through the sander before finishing.
I tried to upload a video but was not successful. This is the way I am leaning with these speakers. I now am able to machine waveguides thanks to my smart brother Rob in Texas. He figured out a way to create 3D STL files by making a gadget and adding to my V Carve Pro software. He said that I should use a 1/4 inch round nose bit and it would require no sanding. I will be happy with minimal sanding. The simulations look good. Tomorrow I intend to CNC some foam board. Sycamore towers baffle WG Tweet.pdf (12.4 KB)
The stepover on the 3D rough out was set at 8% so I changed it to 50% . Now the run times are approx 15 min. rough and 1 hour finish cut. The 6 inch round was finished with a 16% stepover, I think its fine for test pieces but I think the 8% is what I will use on the real deal.
