Wow Andy,
          Sorry to hear that your turbine shed it,s blades. Take heart in the fact that it is still on top of the tower and hopefully your new blades will see it back in action very soon.
  I recall some 9 years ago, in the early Navitron days, We had a member down in Cornwall (I think) He lowered his turbine before a really bad storm. The storm came along and stripped the blades of his lowered Turbine and also damaged his Landy. He had tied the blades as well. I am nearly sure it was a 3kw jobbie and not Chinese.
 Wind is totally unpredictable and you can never be sure how things will pan out,especially if you are in an exposed area.

Hi Biff,   as you can see I have 3 broken blade tips almost the same length.  So the blades still attached are some 12 inches short. Not surprising it was vibrating. I reckon a piece of wood or branch got carried aloft into the blades and caused the damage.  The wind was skurling around that night, but at least the doors are still on.

Still on the bright side as you say the turnip is still up and the tower; plus the PV is er not doing so much in this grey overcast. But still better than nothing.

Cheers.

Andy

Down to the shed today to see about sorting something temporary for blades for the WT.  I have some of the synthetic blades as supplied by Missouri etc for car alternators. I have no idea how much power they will make for me but summats better than nowt.

I had a piece of 10mm steel cut circular by the blacksmith then a precision engineer friend, machined and drilled the plate for the 4 studs on the WT.  This plate will be the hub to carry the 3 plastic blades.  I also got some 50X50X3 angle steel for 3 arms to connect the blades to the hub.

I rootled in ter heap and found a piece of 22mm waterproof ply. This is to be a wooden washer to fit on behind the hub and seperate the metal hub from the metal, magnet carrying rotor. I used the rotor as a template for the ply disc  and wizzed it out with the jigsaw.

I'm aiming for the all up weight to be slightly less than the wooden set as the diameter is less.  The weight has an effect on the overall set up as the hub is off center from the yaw bearing. It's all guess work really but I'm building for strength first and foremost.

If it don't work I'll turn it off and start to concentrate on making Hughes 4mtr machine. So here for the clicky picky merchants.
















Tomorrow if its calm enough I'll put the scaff tower up (again) and see if I can swop these blades over.  Lets hope the paint is dry.

Cheers.

Good Luck Andy,
                 I hope it all goes well. Not having the W/T up and running this time of year is a. Big loss. Even having 400 Watts coming in steady is a real fuel saver. Take care.

Some news on the turnip and plans.

Having obtained a 12 mtr monopole tower a while back a suitable turbine is required. And so, I've been doing foundation design drawings and calculations firstly and last week dropped off drawings and a template for the "foundation root"  to my friendly blacksmith to fabricate. The root in my circumstances is  fixed to bedrock and then shuttered and concrete in. The blacksmith is also commisioned to produce 2 X 450mm dia 10mm thick steel discs for the rotor of the new alternator.

I've been slowly getting materials together for the big build and have got the rear wheelhub from a Peugot Boxer van  stripped and ready for the main hub. Also got some well aged cedar on order for the 2.1 mtr blades, hoping the blanks will arrive in next few weeks.

I'll get some happy snaps soon.


On which note I can't see any of the previous piccys on this thread.  I don't keep up to date much on techy stuff so can any one advise please.  Is this cos I use an oldish pc or some software out of date? Or a Navitron thing?

Andy

Hi Andy,
   Good to hear you are getting going on a newW/T. I have no idea what is happening with the pics. Sometimes mine refuse to materalise also. It might be the lack of strong signal. Looking forward to the pics and details. Sounds like a 2.5kw jobbie. Good luck.

Great news Andy.
Have you ensured ease of lowering into your design?
My biggest regret was the time it took me to lower the turbine.
All the best

Great news Andy,

now, if you're drilling and pinning the bedrock I may just be able to help you out. I do quite a bit of it here at home as we only have a few inches of soil or several meters of peat. Basically it's either solid rock or bog. I'm a great fan of Hilti HIT-RE500, generally buying the stuff out of date on eBay for a fraction of the cost.



So, as I've done rather a lot over the years I've acquired some surplus kit. I have a spare MD2000 gun (the one in the picture) and three 500ml packs dated Feb 2018. A word of caution though, the 500ml packs do not fit the MD2000 gun, I don't actually have a gun that fits the 500ml packs only the 330ml ones. The MD2000 gun is only suitable for HIT-500 which I think is a 4:1 mix. It does not fit HIT-200 which is a 3:1 mix. If you want a gun that does them all you need an MD3000. Anyway, you are welcome to either the gun or the resin for the price of postage.

Hope that makes sense, you can have em both if they're of use but a bit pointless really.

Cheers, Paul

Hi Paul,  sorry not to have responded earlier but you know how it is. Life and stuff gets in the way.

I'd be delighted to take up your offer of the MD2000 Hilti gun if it's still available, I had planned on using the HIT RE500 resin which I think fits that model applicator so thanks very much and let me know how much the postage is.

Today is a "significant day" for me as I've now today,  officially finished full time work and have handed over my driving and management roles to others.  I have been struggling for the last 3 years with memory loss so at the start of the year we decided that for safety reasons I would take a back seat role in the business;  as it's turned out I've effectively made my self redundant. It's a great relief not to have the responsibility anymore. Our growing fleet now runs at 7 vehicles and 16 trailers and it's a lot of wheel nuts, tyres and bearings to keep track of. I have become so conscious of the fact that one mistake on my part could cost lives; loose nuts for example.  See the joke there?

Any way I'm looking forward to getting on with the WT project now, although I will be subbing parts of it out, like welding up the foundation root and hinge base plate and mixing the concrete.

I will keep you posted. Piccys when available at the usual carp quality.

Cheers.

Andy

Hey Andy,

I know what you mean about the memory loss, kinda struggling with it myself. PM me your address and I'll post you the gun when I get back from http://edenfestival.co.uk/SITE/ toilets here are a feckin disgrace but the Peatbog Faeries were truly awesome.



Cheers, Paul
