update on a rusty mill

(1/3) > >>

niall:


we rebuilt this mill back in December , the rotor polyester was on its last legs then and with very few spare neos to replace the rusty ones ....

i havent been back to the site since then and was a bit apprehensive when i called back this week , even with all the good work put in back then i half expected the worst when i rounded the corner ....

so it was a nice surprise to see the mill still running producing good output , no one really looks in on it anymore , i doubt it was ever shut down through the winter for checks on rigging , balance or basically ...well ...anything

a bit of a recap on the work ....


the "front" of the rotors was used for the re cast , the back was too pitted (last pic)



the poly and neos were easy to get off



this week .....at least the air gap looks good , still good clearance ....holding up pretty well really





i,ve no idea the kwh its produced , but i,d say its payback period is well passed now ....its on a good wind site and has spent a lot of time fully furled .....

If only neo had some of the properties of ceramics, and the power of neo's.... it would be nirvana

its hanging in there alright ....it may write its memoirs one day , would be an interesting read ...

strangely the original bearings ( which were second hand to begin with ) are still in place , with no back seal ...

i think this had something to do with the solid cedar prop, which is ridiculously light.....

still ....i shouldnt temp fate , corrosion is hiding in the long grass somewhere .....for now       

bj:
   Always nice to read a success story.
   Hopefully the next time you see it you can post the same results.
