I did know Hatch was your brother, hense the idea to hit him up for some timers, yet it seems you have some sources of them too
Do you think you could get a hydraulic cylinder to cycle fast enough to operate as a tapper? As it is already hydraulic, i understand why you really don't want to add another energy source to it. I was most impressed with your setup when i was starting my MC automation build, i like the fact you used bits and pieces you had laying around. Mine was a very cheap build, i had quite a few parts, and what i didn't, i got off a friend of my dads that has loads of surplus parts that he just gave to me.
