Here we go! The last blog post before I go to Makerfaire NY 2013 next week! And this caught up to last year’s out-of-sequence post about Makerfaire NY 2012, so I’m less than a year behind in my blog now!

Made it on my lathe. I think they did sell it on MendelParts.com, yeah.
It’s given me enough problems that I’m not bringing it to Makerfaire this year. I may even make an old retro nichrome-wire-wrapped one if I run out of time. 
Yikes! That thing was a nightmare for me. Sounds like you need to make friends with reifsnyderb before Makerfaire.
