Awwe, just noticed the thread. Heartfelt condolences to his family and whom all he touched.
I personally never met or corresponded but often read his commentary's on CR. Will add, my lurking and interest in the hobby includes admiration of the artistic 'drillium'. Always at the top of search engines is Jon and Drillium Revival. I've often come back to view his gorgeous and tasteful work. The soul and passion put into each part is one of his gifted marks.
R.I.P.
