I seem to remember several on here removing all grease and just running a spray of light oil in the bearings. So SuperLube should do the trick. With a rating from -45 to 450f I don't see it melting out or anything.

No good reason to post today, just have some free time and an update: "Still OK"...

That's a good enough reason, and tells us that you're still alive too!  B^>

Spirit of Zubbly was lowered for servicing today.  In the end, just grease on the tail shaft and yaw bearing were
needed.  A squeak had developed, which could only be heard during storms strong enough to raise the tail, so it
was obvious where it was coming from. When I disassembled the tail's pivot, I found nothing but grime was left
inside.  Since I never did anything to seal the grease in, I just cleaned the pivot, re-greased it, and I'll cross my
fingers for another 2 years noise-free. 

Speaking of grease (remembering a previous discussion on the subject) the shaft bearings are running as smooth
as ever and I haven't heard any squeaks on deep-freeze days like I was before.

Nothing was particularly rusty or needing work, but I sprayed a bit of paint just to pretty it up again. The rubber
tail bumper has some cracks but is still solid, while the rubber vibration dampers have no cracks and are still firm. 
No loose bolts were found and normal play was found in the moving joints.  The blades will need to be re-finished
in the summer.  Every time I work on this machine, I silently say "thanks" to the guy who inspired the project and
showed me how to make a durable and effective machine.

Here are some pictures after the job was complete.

Nice to see it still running Spar.

It is interesting that the best windmill for overall durability has been the Zubbly conversion. They are not the most powerful, but they are the best long term performers by a mile.

Sadly I have built plenty of the axial style, and none of the Zubbly style.... you went the right way, I went the wrong....... bummer really...

I have some huge 8 pole motors ideal for this.... but mills are pointless now with sub dollar a watt solar.... I have way too much power now.

Oh, sure, if the $$$'s were the only deciding factor, we'd all go solar today.

In defence of Wind turbines.

 I have 3off Hugh Piggotts design, 12 footers.

 Its winter here in rural Normandy France, so its grey, dim, wet, and mud mud every where!, week in week out.

We are only 50 minutes from the coast, so we get reasonable winds that keep us going and keep the batteries alive. No generator here as it defeats our philosophy of sustainable RE.

However, with good panels we still get 10%, approx., from our 8kW of PV installations. So I am re-calculating cost effectiveness on worse case scenario of 10%, so just another 22kW of PV to go until paradise ......... :)     
Everything is possible, just give me time.

Re: The Spirit of Zubbly flies again - Hail Damage
« Reply #35 on: August 06, 2016, 12:00:17 PM »
A heavy hail storm blew through last week.  Still finding the damage in the darnedest of places.
Crops destroyed for miles around.  The hail fell continuously for 15 minutes (not the typical rain-hail-rain kind of thing) and the size of the balls grew from marbles to golf balls... and remained between golf-ball size to ping-pong ball size for several minutes until returning to marble size for another 10 minutes.  My house was relatively well protected by a shelter belt of trees (yeah, that's what they are for!) but my garage window is still shattered and the exterior siding is punctured in 100 places.  The reason I'm writing is that there was also damage to my Spirit of Zubbly.

As you can see the trailing edges have a bunch of bites through them.  It was shut down during the storm so I'm hopeful that the leading edges aren't damaged.  It was breezy yesterday, so I started it up, and it does make more noise - not too much to be disturbing.  No vibrations to be felt through the tower... I may leave it up and not worry.



The other thing to fix was to replace the cups on the anemometer


Here's a picture to illustrate the severity of the hail.  After the storm, my wife and I drove around the neighbourhood to survey the damage.  Crops of barley, peas laid flat.  The kicker was the potato field where this was found.  The hail first scoured the earth covering the potatoes, then it PEELED THE POTATOES.

Our new potato-peeling hailstone-storming overlords are to be feared!  B^>

Hiker,
No joke - The hail dug into the earth and did that to acres and acres of potato fields around here!
The wind also trashed the tops around enough to pry them up, making it worse.
