Please post a thread somewhere on what your doing and using. I like to see what others are up to.
Industrial user, Cottage industry user, Job shop, Casual maker and home shoppers all have interesting experience that I learn from. I must say a couple home shop people I follow closely are by far the most experienced and talented engineers, machinist and builders that share their work on the net. 1/4 scale 12 cylinder Merlin engine complete with blower is just one example that comes to mind.
Anyway I like your picture. I did the mx thing for a few years long ago and still an avid fan. Didn't last long because I didn't understand how to ride at 80%. Always went 110+% and the results were broken machines and inconsistent finish. A lesson I learned much later in life playing golf of all things.
