Very posh work Andy,
                   Like N2 says, it is almost a pity to bury that lovely galvanised gear but you are right, You will not have to diddle about with it ever again.
  Great pics and very impressive.

That lot's far too nice to bury in the ground! Grin

The Ancients did it all the time N2, just think in 2000 years time when the archaeologists dig it up they'll have hunners of theories  Grin

Cracking work Andy, youre really making this one a bit special.

Im just started an evening class in learning to weld and one of Hughs turbines is sitting in the back of my head as a possible project to work on next year

Go for it Mr MF.  Do the welding course, get some scrap metal to practice on then go for it. My welding has improved no end from practice.  I really learn't from watching an expert.

I'd suggest building a 2.4 mtr HP turbine to start.  Not so big that it's difficult to handle on your own; but big enough to give a decent out put, 750w or so.

I figure this will be my last big project so I'm trying to use all the knowledge I've acquired over the years to make it something to be proud of.

7 Lbs of marmalade made this morning . We freeze the Seville oranges in 7 Lb bags, whole,when we buy them in January. The big autumn tidy up and gardening duties for the rest of the day.

Back on WT tomorrow.

Cheers.

And buy good quality equipment!! A bad workman always blames his tools but in some cases it's true.

Mr MF, you will enjoy welding and find it very satisfying when you make something that is strong and rugged. My first few attempts looked as though an incontinent pigeon had meandered across the job, but once it clicks and you get the knack, you will show your work with pride. Practice may not make perfect, but fitness for purpose is the important thing.
If you ever get stuck, there's a zillion tips and tricks on youtube.

Yes Ive browsing YouTube which is very useful

On the recommendation of the migwelding forum Ive bought a Portamig 235, probably overkill for what I need but itll handle anything from thin sheet to girders. Current projects in the barn include fixing and reinforcing a trailer that has broken and repairing some of the tractor bodywork and an old link box for it. PLenty to keep me busy.

First project though will probably be a welding table for the workshop which I can build as a project during the course. Oh and I had 16A supply points put in the barn and workshop when the rewiring was done so I have the power available for hefty machinery.

So I got a mini digger in for a day on Thursday and got the turbine base site down to bed rock.

Whilst the machine was here we also cut and leveled a new track and level base in the field for a pony shelter.

Very boring pics of a piece of rock for today chaps.





The root section has to set into this rock base.  1st thing I'll do is shutter up say 75mm about 750 X 750 and make a level concrete plinth where the root section must go.  I'll then drill down through the concrete pad into the underlying rock; a series of holes to accept the rebar legs on the bottom of the root section.  I have a plywood jig with the holes set out which I can drill through. The legs are then bonded in with the Hilti mortar.



I see a couple of the rebar legs have got knocked out of square at some point. I'll have to straighten them out before final fitting.

Cheers.

You are getting there Andy,
                      I never thought there could be so much work involved but Paul on Rasaay had a similar root to his tower..
  I think that i got away light with the 8 guys, Grin

Thanks for words of encouragement guys.

It's been dry today so I got my concrete pad cast, only needed 2 barrow loads so not too demanding.  I'll leave it to cure of for a few days.  I did add a bit of frost proof/accelerator and the pad is covered over in case of frost.

Things are starting to come together at last but i'll still have to wait for 6 weeks or so once the ready mix is in.

I've got some shuttering ply coming up on a wagon on Tuesday so I'll be able to get the pad properly defined and set out.
Mustn't forget to put some 100mm flexible trunking in the bottom for the cabling back to the shed.

Home grown lamb, potatoes, greens, onions and parsnips for supper tonight so I'd better go and cook it.

Cheers.

So a bit more progress down on the rock face.  Got the shuttering ply cut and in place before last week ends wind and rain. I had planned on a circlular base but ended up making an octogan as it seemed simpler. Took a peek 1st thing Saturday morning and I had 6 inches of water  on site and rising, so we had to dig a small leat to spill the pond away then I cut a perimeter channel to drain the site. Rock chipped out by pick axe OW!

Since Monday I've been getting the steel Hiltied into their now dryish holes.  I spoke to Hilti's tech dept who reassured me that the presence of moisture or wet rock faces didn't effect their product. Then progressed on to getting the rest of the  rebar in place and reinforcing the form work. Hope its strong enough now. I've got 2.5mm sheet metal corner posts with 18mm shuttering ply.  The center of each panel is braced down into the ground and the top perimeter is braced with 4X1. 2  off 5 tonne ratchet straps around the girth complete the ensemble.   Total weight of concrete is around 8.5 tonnes.

Plan to pour on Monday. So I've got to drop the scaffold tower  to give the wagon a place to park.  I've used some old tin to make some chutes which I need to assemble and make any supports needed. The ready mix will be parked about 2 mtrs above the site base so hoping not to have much to do with wheel barrows.  I'll do the vibrating poker.











Before I back fill I'll drop a bit of plastic drain in as some of the water was coming out of the rock face so it needs to  sent on its way, not blocked in.



Cheers for now .
