Ok guys today was big day. I tried drilling the copper. it worked but not as well as I wanted. I released that the copper block were not big enough to have 3 barbs like I intened so I am changing my design to a 2 barb block. Also released that the the mistake I made while drilling are not that bad and work well when water was sprayed on.
I also worked on the chassis. I put the putty on. I also started to prime the top panle. When I started priming, I then wanted to mod my MX 1000 again. I wanted to paint it like a red. A candy red, or a dark deep metalic red. So I started to take apart my MX1000, and then wanted the keyboard rist rest painted the same as the mouse too. So I to that sanded with 240 using sander, then 320 wet sanding by hand.
I also filed down the copper block and sanded it with 240. Looks better now.
