Start with your favorite plank of wood. I choose bloodwood for its rust-color. Use a hole cutter and cut the ID holes. Cut the through hole first then the ID. Fixture your piece securely, the cutting blades are going to want to jump and grab the hardwood. Just like metalworking, monitor your feeds/speeds. Bloodwood is dense and you can burn out the blades if youre in a hurry.
Use a wood rasp to clean off any tooling marks, and mill the shape to a clean circle. This is the most labor intensive part. I cant imagine doing this without a drill press.
Use a jigsaw or scroll saw and cut the OD, around the perimeter of the ID circle cuts. Use a rasp to clean off tooling marks. Take your time, make sure you have a near-circle, that's smooth.
Start sanding with 60-100-200-400-800 grit paper.
Use tin snips/shears to cut the perorated steel mesh.
Test fit all the parts.
Here you can see the sanded earcup on the right and the second one I just cut on a jigsaw. If anything error on the safe side and cut it too large. You can always whittle it down in size.
Nice napkin rings!!
Make sure you drill the mounting holes in the EXACT location. If youre off by too much the earcup will not fit the headband "C" part, or it will be lop-sided from right to left. Take your time and make sure the sides are symmetric.
I goofed at this stage and had to re-do an earcup.
Half woodie. Test fitting things.
Close-up...
Thats all for now. I ran out of hot melt glue so the mesh and HF-1 logo are loose.... what grado would be complete without hot melt glue?
I'll tung-oil the bloodwood this weekend and finish up on the assembly with hot melt glue. Not sure what cable to use yet?... OEM or star quad?
More pics to come....
