Blade station templates for "otherpower" style blades?
« on: May 16, 2012, 09:46:06 am »
Just wondering if anyone has the station profile templates for the common "Otherpower" blades?

I am realising I need to carve my own set and, while I have several of the DIY books, I cannot seem to find the station profile templates in them.  I know I saw them once in a PDF or other computer file but cannot seem to locate it now.

Also, techniques seem to have improved from "the old days" enough that there may be easier methods to use. I do have a 12" Craftsman band saw but no wide blades that will track through a board straight enough to use that band saw method.

I need to carve 3 6 foot blades for a 12 foot turbine. Like this:



Who knows? Might get good at it and build a little cottage industry here in the stix.

Any help appreciated.

Tom

tom-
i can't help you with the station tables.  i did my own off a blade calculator.  have you ruled out the OZ chainsaw method?  i never would've carved my own blades if it wasn't for the chainsaw route. 

my offer still stands to rough out blanks for ya!  it would take some time for wood drying reasons though...

Tom,
I hope this is what you meant.

You should try the chainsaw method. I just finished a new set for a 10 footer. Cannot believe how fast and easy it was.
oztules is my hero!!!
It took longer for the paint to dry than it took to make the blades.

Adam;

How long to dry? I could set up an enhanced solar drying area for that size wood pretty easy.

Any links to "how" they set up those chainsaw jigs?

Chainsaws I got in several sizes and I have thousands of hours running the things, to boot!

Been watching the youtube videos but none show how the jig is laid out just how to use it.

Thanks.

Tom

Maybe oztules would be so kind to repost that guide here as well?
Possibly with any updates or new thoughts/ideas he might have discovered since?

Before you put blade to wood check out the sticky by Menalos (Max) in the wind section of fieldlines, with just a little change he has made blade carving a lot easier and faster.

I finally took my own general advice and Googled up the article Oz did over on The BackShed:

http://www.thebackshed.com/windmill/articles/ChainsawBlades.asp

I haven't digested it all but the basics are all there.

Big thanks to Oztules for the article and http://www.thebackshed.com for putting it online.

this may sound finicky, but this is how i like to do it. 

*moisture leaving wood in a rapid time is what causes warping*

1) buy clear fir 2x3's from home depot at $1.63 a piece.  i buy WAY more than i'll need, so i can weed out the bad boards as the process goes along.
2)cut the good parts out, and let them sit in shop for 2-3weeks. 
3)resaw 2x3's into smaller straighter pieces, let sit in shop for another 2-3 weeks.
4)run all boards through plainer on all four sides to ensure flat and true. 
5)let them sit in shop for another week.
6)pick out the blade stock and glue up one layer with gorilla glue.  i like to make my blanks with two layers with offset joints.  so say 5 boards wide on the bottom, and five boards wide on the top with half the width offset to get a staggered glue up.
7) glue up the top half.
8)individually run the top half glue up and the bottom half glue up through the plainer.
9)glue top and bottom half together with gorilla glue.
10) rough out with chainsaw.

as far as the chainsaw jigs, i just draw out each station full size to get the correct drop ect. for each station.  then just add the offset for the chainsaw guides/slides (steel bolted to bar) and you can cut the sides of the jig with a jigsaw. 

now if someone just had an unlimited stock of clear straight 3x10 redwood, this process would be soo much easier!

Dale;

Well, fab, I think that is the bees knees as they say.

Less jig work, less cutting and hopefully something I can pull off.

I generally just skim the blade carving posts because I never figured I would do any myself. A manly tool like a Stihl chainsaw changes that compared to hacking with a spokeshave or draw knife and hand saws (none of which exist in my tool arsenal).

Thanks for the cluehammer blow.

something like this can be kind of usefull for checking and setting up the stations.....

rough first version.....(the blade caculators also give the angles as well as the "drop" measurment



i think oz,s were 3 degrees at the tip , 6 in the middle and whatever you,ve got left at the root ..(otherpower is the same i think ? )

I don't have a decent hand saw, or a spoke shave etc..... but I have a few chainsaws... and they work well enough for this type of thing.
Melonos has a good idea there, and is what I would try next time.... just change my jig to suit (still up in the shed I think).

It's nice to see a few other people have done the chainsaw method, and have been happy with the results. The real difference with their attempts and mine .... seems to be they did a nicer/better job than me.. :-[

It is the easiest way to make big blades that I can envisage for the least set up , and simplest equipment. .... even I can do it. :o

The blades made in the second section (update ) of the backshed article were for a very stiff alternator, and the more usual "dans" cord and thickness would better suit your alternator.

Best with it Tom.


..............oztules

edit..... and Niall, thats a good looking angle rig.... and best use yet for old cd's (I think thats the indicator material?).... I must make one  next time.
