ah, spools- Think I may have described these before. I normally take an 8 foot 2x4 and cut into 5 pieces equally. take 4 of those pieces and cut a 3/4" deep x 3 1/2" dado in the middle. these become the "x" on the ends and the last one is the spindle. I use titebond 3 glue and 3 1/2" decking screws and glue/screw x's together and the x's to the spindle. be warned-don't just use nails or screws, been there, done that. these fit on a lazy susan platform we build to spool and unspool c-9 lights when we install/takedown.
