Looks like you put a lot of effort into the board. Gotta hand it to you for that. But i stand in agreement with Debi. They are not for the faint of heart. And im sure even experts can get hurt with these boards too. I know from a little experience.
I built one, since i was a teenager who only knew of ouija boards from youtube, and i liked to build and invent stuff.
I destroyed the thing with a hatchet after three times using it, without a regret. They can be very dangerous if you dont know what youre doing. Id tell you what happened but i dont wanna waste tread space and i think Debi did a good job explaining what can happen. Ive been phsyically hurt as a result of using it, but then again i had no experiemce or expert advice or training.
At the end of the day its your choice what to do with the board. If you proceed, take all the advice, even training you can get. Stay safe.
