A day at the "Jerry" blade factory.

[Jerry]

Here saome pix. Some of the parts prep have been covered in earlyer post.

here is a group of 4 three blades at the asemble table.



Parts lined up for count.





Nuts, bolts, spray greese, drill, clamps and hand tolls used during asembly.





asemling the parts. The littel soft hammer helps in the part alignment prosses. It doesn't bend thing.





Under side. #10 stainless steel machine screws get trimed close with Dremmel tool using heavy duty Dremmel cutoff wheels.





Finnaly got 4 ready to ship. I diasemble for shipping in a 6"X8"X 24" box. Buyer reasembels upon reciept.

OK Dinner time now.

A couple pix of intrest? With the 2"X2" mounting tab cut off the 1/4" thick root end center is visable. Root is 5/16" thick at the edges. Tips is 1/8" thick and all edges are rounded off. Cup and twist gives good stringth along with user added aluminum sheet metal support.

Blade is 5 and 5/16" wide at root and a rounded 2" at the tip.

Twist or pitch is 23 degrees at the root to just a couple degrees at the tip.

Great pictures, Jerry! We al vorgive u 4 ur speling!

Puter seems to be working without problems.

  I like the hubs I guess one of these days I'll

make a hub like that for my 6 blade that I'm

making out of wood for now.

  Just dreaming ....

  Yesterday was an above average day 7-9mph wind

with ocassional gusts up to 10 and 11mph.

                Still Havin fun in NE Ohio

How many watts does that setup make ?

What RPM does it do in a 10 MPH wind ?

[nothing to lose]

"Finnaly got 4 ready to ship. I diasemble for shipping in a 6"X8"X 24" box.  Buyer reasembels upon reciept."

What does a set like that cost?

[Jerry]

Hi domwild

My wife laffffs when she sees all the miss-spelled words in my posts. I just tell her these guys don't care about spelling just content.

Generally when I post I'm in a hurry or real tiered so I don't care either. I know you guys can sort out what I'm trying to say.

I think I've seen other folks miss-spell sometimes also. I gues if spelling correct was requiered here there would be fewer posts.

Besides I only have one typing finger the rest just drag along for the ride.

Please forgive my illiterasy?   LOL

Hi Woof

Not sure on rpm at 10 mph? Here is the wattage mph figures for the 1 hp GARBOGEN conversion.

5 mph 63 watts, 10 mph 100 watts, 15 mph 250 watts, 20 mph 379 watts, 25 mph 510 watts, 30 mph 650 watts, 35 mph 903 watts and 40 mph 1040 watts.

I have seen at 45 mph 1200 watts from a 6 pole 3/4 hp conversion.

I think this is evedence that these blades don't stall in high wind like the plastic pipe blades do.

I've taken lathe rpm test #s from motor conversion and then checked the same output in a wind on the same conversion but depending on the capabillity power wize of the conversion the rpm will vary.

This is something I should test and form a graph or table on?

I'm sure top blade rpm is well over 2000.

I'll try to get you some 10 mph rpm #s in the week to follow?

Would they be overkill for a half horse GE ECM?

(will probably split up the coils in pairs)

Hi Norm

Those wind #s are low but concider this. There is 100 watts available there and a motor conversion is cheap and easy and how much does 100 watts of solar cost you and does solar work at night or how good on a dark winter day?

How many small wind gennys could you build for the price of a 100 watt solar panel?

                   JK TAS Jerry

[Jerry]

Hi Nothin to lose.

Here are all the $#s.

Blades    $15 each.

1/4" thick steel hub $50,

Hub to shaft adaptor in 1/4", 5/16", 3/8", 1/2", 5/8" and 3/4" $10.

Aluminum sheet metal blade supports $5 per pair 1 pair requiered per blade.

A complete set of #10 stainless stell screws, large flat washers and star lock nuts $5.

Preasembled ready to reasemble 3 blade complete $150.

The blades are the hard part you can't do the other stuff you can.

Just be sure to follow my examples of support and root angle and you'll be fine.

Hi ghurd.

They are perfect for the GE ECM motor. I'm flying 4 GE ECM motor with this blade its a real good match.

I see around 250 watts out of the ECM at 30 mph. Seeing over 100 watts at 15 mph.

This is with the 1 hp with my coil reasignments. Also have 36 5amp diodes on this conversion. This conversion was covered in a post a while back.

Not bad for a motor pulled out of a dumpster and a hand full of 25 cent diodes, 3 $15 blades and the rest made from junk.

Lets see the solar guys match that?

Hi ghurd.

I was just rechecking the #s for the ECM conversion cause they didn't seem right. They wern't.

Here is the results of my mod that consists of seperating all 18 coils. Then wireing 2 coils directly accross from each other in perelell. Then wireing all these 9 groups in star. Here are the wind #s using the blade in this story.

10 mph 30 watts, 15 mph 97 watts, 20 mph 163 watts, 25 mph 280 watts and 30 mph 380 watts.

Prety close to an AIR-403 but way cheaper and way less noise. Although I've seen 650 watts from a GARBOGEN at 30 mph.

Besides I only have one typing finger the rest just drag along for the ride.

After 20(!) years of computing I've finally decided that it's time I learned to touch type (rather than then 45wpm two-finger method I use now).  I've written a not-terribly-good typing tutor program to help me with this, and here it is:

You can download it by clicking on this link

It's written in Visual Basic 6.0, so you'll need M$ Windows.  If you get a "missing runtime files" error, try downloading and installing my meter dial program first.

I'm told that it takes a few weeks, and accuracy is far more important than speed in the early stages.

Enjoy!

Got to love productivity.  I guess your keeping the super duper automated robotic assembly line a secret for now.  Looks good.  You could add a few kits to E-Bay for a trial, just set the start or reserve price at your asking.  The only kits I generally see in that size range are like the Hornet blades, which are reported to have noise issues, or made of aluminum, which it seems to me would fatigue pretty quick.  Rich

They look Great! but I don't think i'd sleep with them....

"but then again???"

[ghurd]

I only have 1 ECM, a 1/2 HP.

Kind of figured, after reading your posts, that something around 3' dia would be a good start for a 1/2HP. Less power but a little faster.

At 18" each, we are going to have a try at carving a set. Or 2. Or 3...

It's on the back burner, either way.

G-

[Jerry]

Most of them I've collected have been 1 hp. I do have several 1/2 hp and 1/3 hp.

I'm going to modify 1 of the 1/2 hps for my motor home.

I use a pop up mast when camped. Not sure about the noise? I'll find out. The TDM I use now is fairly quiet.

Hi Jerry

i type with 1 finger to [it's broke]

can't spell [who kare's]

can't see [firefox fixes that] so it don't matter.

i allways look forward to your post's.

very entertaining and always good info.

having fun

later

  funny i was planing a post about the results of my 3/4 ecm with these blades

 first mine is wired with #10 wire all rectifiers are at ground level the three coil

sets are opened and a pair of #10 to  rectifier to make 3 rectifiers  out puts 2 amps or about 30 watts in a slite breeze in good wind it avarages maybe 4 amps

heavy wind i have seen 10 amp only once and 5 amp is the norm. not very technacle ?

 information but i dont have a wind meter and this is a toy anyway .one thing to note

is this setup will stall even in heavy winds with just 2 halogen car head lights on the combined rectifier outputs kind of a brake. so next time i can talk someone

into climbing up and taking mill down < i cant climb> i will try jerrys way as he is getting better results  george  ps amp results were using a battery 3/4 charged
