Always wanted to get my mount to have partial through the mount cabling. Rebuilt my power box and got the cables down to 1 silicone power cable and a thin flexible Ethernet cable. After some thought, I found a way to avoid cables affecting the RA axis.? After running slewing tests in the house, I had 2 clear nights this weekend to try it out. Cable did not catch on or touch anything. Guiding was great! Just had to make one small 1/4-inch channel in the RA extension.?
