Thanks for all your kind words. It's been three weeks since I touched it and three weeks since I checked the site. While life has been quite busy, especially in the past few days, the truth is that I've been pretty demotivated and my thoughts have run along the lines of, "I could carry on from where I got to out of the internal fan curve and save all that time rebuilding the start of the ride...but rebuilding the end is just too much of a hassle. Or I could keep going the way I am and just hope that everything I've done so far lines up, and have to rebuild the entire lift and all the track through the internal fan curve." I think the answer is jut to pick an option, be happy with it, and get on with building. Thankfully I have a day off work tomorrow as it's a public holiday. I will write you all another update then even if I don't actually end up achieving anything. Accountability is key. Happy Easter!
