I so agree with you on making things from scratch it is such a feeling of gratification to see it all come together.
My wife's first staff was entirely PVC tubing & fittings that was based off of the Hasbro & Sideshow 12" figures, which has now been replaced by a 3D printed one. There are only about 3 maybe 4 very poor screen grabs of the staff. There are some good photos of the tip but the lower section is left up to interpretation.
I look forward to seeing your interpretation of this come together.
