I received an email from Claude about his mini-mill, he included a couple of photos and I thought it looked so good I decided to post it here. It was based on my Mini-Mill design here. Claude's email... "Here's a windmill made by following your plans for the stepper motor windmill but with a little upgraded electronics. The miniwindmill has small stepper motor that charges a 8.4V/400mA battery. It also has a light sensor and a single LED as a light, pointed down from the tale. As the night falls, the little LED lights up for the entire night. This little windmill is working for more than a year already and it faced some severe storms with no damages. The body was a elbow flush used for toilet tank. Claude" 
Well done Claude, it looks like a bought one! Its also inspired me to dig up my original Mini-Mill ( the one photographed in the article ), its been leaning against a rock and over grown with grass for the last 2 years. I found it this afternoon and although the timber tail is gone, the rest is in good condition and still turns. A new tail and some oil should have it working again.

Hiya Glenn, Mate i made up a mini mill akin to your design ages ago and recently I ressurected it and made some blades out of pvc as per your webpage. The little thing was a beauty untill we got some real strong winds and I wondered from the house why it wasnt making a noise. On inspection I found the pvc blades had literly disappeared and only the base of the blade was left. I also learned a valuable lesson on my first F&P genny, silly me only had a 6" clearance between the blades and tower and 1 of the blades hit the tower and smashed. Cheers Bryan |

Bryan I have also had the same happen to minis, tower to tip clearance would have to be one of the most common failures the novice mill builder encounters when starting out, come on hands up who's done it  obviously very dangerous with metal blades, you put in a bit of work to make it look good, you think it will be fine then one day you check your mini or maxi only to be shattered  |
