Thanks @kad2371. Actually looks easier to rebuild than the kayfun. I find the balancing act of holding the coil in place, wrapping the wire around the post and tightening the screw very hard to do on the kayfun. Literally took me an hour to connect the coil after taking about two minutes to wrap it. Re-wicking also looks very easy on the CLR.
Got an ego adapter and a small block of wood?
I drilled a 1/4 inch hole in a small block of wood, press fit the 510 end of said adapter into it. Great building base to hold your topper for attaching the coil. So I don't have to hold the coil, base and screwdriver. Yeah, I only have two hands!
