A few years ago I joined a local woodworker's group. Most of the members, all male, made their living building furniture etc. I was the only one in the group that owned and used a CNC. Before buying a Shopbot I taught high school woodworking for 35 years and built many pieces of furniture in my pre CNC era. I wanted to do something different. When I joined I offered my CNC services to anyone who might benefit. I was almost shunned, particularly by the older members of the group. I was older than any of them except for a few hobbyists. They never actually came out and voiced their objections but they didn't make me feel all that welcome. I usually make friends fairly easily but never made a real connection to any of them. I gave it a fair shot, stayed as a member for 5 years, exhibited in the annual craft fair. I also tried to get them to see the advantages of using social media and Sketchup to no avail. I left the group two years ago.
