Poa (Jon) was a walking book of knowledge when it came to vintage miter boxes.  Both in terms of history and knowing how to use them.  He was also exceptionally generous with his time, knowledge and spare parts.  Anybody who frequented the Miter Box of Your Dreams thread on LJs will know him well. 

You got DrSurfrat.  I got to know him very well over the last year or two of his life.  He is very missed both online and off.  He was a theoretical physicist, a devout catholic, a doting father of two little girls and went from being extremely active to passing from cancer in a matter of a couple of months.  Probably in his late 30s leaving two little girls not even old enough to drive.  When he first got sick, he said he wanted to turn a vase for a friend but couldn't find any stock.  So I cut him a blank of Cherry and sent it on the way that day.  Over the course of two weeks he found the strength to get it mounted between centers and sent me a pic because he didn't want me to think he wasn't going to use it.  His wife contacted me when he died and told me it was still on the lathe unturned :-(  Cancer is an asshole.
