Don't learn from me...I am just making it up as I go lol.
I spent the day on other projects since I couldn't do anything to the Obi until my end mills come in BUT then decide to add to the Obi anyway. I decided I wanted to put a crystal chamber reveal in it.
The way I am doing it is by taking some solid stock I have and turning it down and then threading it. That is all I have done today. Next is to bore it out, design a cutout for it and the brass internal crystal mounts. I also need to find the crystal I have been saving for such a project. I hope to have some time to do at least some of that tomorrow.
Now I didn't want to rework everything so I decided to keep the screw on grenade section. To do this I found some 360 degree slip ring wires that are rated at 2A. This will allow the wires to freely spin without twisting up. I have ordered the slip rings and hope to have them early next week.
Here are the pics. I am going to machine out a speaker holder in the bottom threaded part which will clear up the pommel area and make it easier to get to the SD card.
