One approach could be to set up the mast using rope or chain to get some actual
measurements, then go down to the hardware store and purchase the length of
cable you need along with the fittings and hardware including a swaging tool. 
Then make up your own cable stays and shrouds.  Making cables is really easy and
it saves money.  Just another possible option.

Thanks.  My son Brandon and I are also getting excited about getting up there. 
We took the Flash down to El Mirage last weekend but the wind never set up for
us.  Oh well...

Really glad the fire missed you.  That must have been pretty scary, especially
at the point of having to evacuate.  You may have to start building those
Wingnut boats out of asbestos.

See ya at Alvord, have a safe trip.

You may have noticed that a new link was added.  It's hard to tell what is
"new", so here it is.   Lots of good stuff, but I found while looking for
bushings for my steering wheel that drives the T-post, plus a bushing for my
front runner and bushings for my cockpit steering assembly.  If you can imagine
the bushing ... they have it.

http://www.smallparts.com/

Hope you get some rain soon!  You make me jealous how fast you can crank a boat
out.   I'm at a disadvantage in that it's not being built at my place ... except
now all the parts are home so I can pick away at it.

Hey, I didn't tell you I found a big enough sprocket for the T-Post!  It'll be
slick.   I have a 1.25 keyed go-cart axle and a keyed hub to mount the sprocket
on.  Also using a go-cart steering wheel to drive the chain.   Nothing to look
at yet, but I will soon

BTW: The next pics I post will expose your ST49 Pod design.  :-)

John,
I haven't posted pictures recently on construction.   You have the best pictures
on that.  No point in showing my hack job.  :-)

Anyway the wings are built and primed.   Planks and springboards are done too.  
We did the J14 style planks ... top and lower skins in ash, with pine stringers.
They are actually VERY easy to build.  Vertually no shaping because the
stringers govern the thickness of the plank.   Conrad is stretchin his ST49 a
bit so made his wider and thicker.   It turned out a bit stiff and very little
rebound on the arch.  Mine was done second and after being a little gun shy,
mine may be opposite (too little arch and a little soft).   Plank was finished
with unidirectional glass and a good UV spar varnish.

Now I'm working on my composite hull (urethane foame and glass).  Just cut out
the foam last night.   I'll post pics on the glue up since this is a little out
of the ordinary.  Not the cheap way to do it, but I've been itching for a
project like this.  That's the justification.   We have enough foam to do side
cars too, but not sure if we'll get to it this season.  ONLY if time permits

Very little done on the hardware yet, but I did weld up axle plates and rough
cut the runners.

Dave

Mike

Thanks.  That's got me thinking.

I know at least one of the big A-class stern-steerers has a fairly large
jib-crane mounted to the trailer (with out-rigger legs to stabilize the whole
thing).  The crane is used to lift the pieces off the trailer onto the ice for
assembly, as well as helping to step the mast.

All the big-boats I know of use at least a gin-pole, if not some kind of crane,
to help raise the mast.

Cheers,

Geoff S.

Overall the ice boats are beautifully designed and detailed.  Enjoyed watching
some of the videos.

On the really big boats it looks like it would be rather difficult standing
those super tall masts.  Have there been any attempts at mounting a winch on the
trailer and using it to help stand the mast?

The boats are stability limited.  That means that you cannot develop more force
on the sail than that required to un-weight the windward rear wheel.  Any more
force, and you tip over or hike big time.

The line of action for this tipping is a line between the front wheel and the
leeward wheel contact point.  Since the largest movable weight on the boat is
YOU, the further you can get from this line of action, the more righting moment
you have and the more power you can pull from the sail rig.

Since, in general, we sit on the center-line somewhere, the further aft you sit,
the farther you are from this line of action and the more righting moment you
develop.  [As a sidebar, the speed-record machine pilots don't sit on
center-line.  Iron Duck had asymmetric wheels and Green-Bird had the front and
rear wheels on the fuselage, with the plank holding the leeward wheel.  They had
a fast-side and a slow-side tack.]

Your wheels develop friction resisting side forces up to a level equal to the
coefficient of friction times the normal force (down force) at the wheel. 
Sticky tires have a higher coefficient than hard tires, but not too much
different compared to the magnitude of the normal force.  If you balance all the
forces on the boat, and you want a neutral helm, then the sail center of effort
would be directly over the boat center of gravity. This is from a view
perpendicular to the line of action.  (presumes front and side tires have same
coefficient of friction)  At maximum power, remember, the windward tire is
unweighted but has not lifted.  Its side force is equal to  the normal
(vertical) force at the tire times the coefficient of friction. Normal force,
zero, side force on windward tire, zero.

Since you want just a little over-steer (rear wheels break loose first), then
the center of effort of the rig should be just aft of the center of gravity of
the boat from the same point of view.

Remember that in a reach, the sail is sheeted out (wing is set up angled to the
boat center-line) and the center of effort of the rig is forward, not where it
was when the boat went to windward, wing on centerline.  You still want the boat
to have either neutral or slight weather helm (over-steer), so pick a mast step
and rake condition so in the reach, you still have a stable steering situation!

Moving weight in front of the wing puts lots of weight on the front wheel, so
steering is possible through a wider range of side forces and unbalanced
conditions (the front wheel doesn't want to slip or skid), but this moves you
closer to that line of action, making the boat more likely to tip.

John did the testing or analysis on boats that work, and wrote the summary of
how to balance these forces as well as to balance the "wing pitching moment" by
adjusting rake and area in front of the wing pivot line. Find the discussion in
teh files section. That stuff works, and there is no magic.

Just engineering.

In my experience...the further forward the sail/wing's center of lift is the
more tippy the boat is; the further aft it is the less tippy, but the more
likely it is to "oversteer" drifting the back wheels. As mentioned, moving the
pilot's weight forward also makes the boat tippy, like pushing into the empty
area on a 3 legged stool. Iceflyers mount the mast really far back, but rake it
forward and, at least the guys I've seen in the dirt, run HUGE sails.

You are kind of mixing soft sails and wings ("amidship"), you can't really do
that.  If you were to put a wing mast where a soft sail mast is, you would end
up with dangerous lee helm (if the boat gets over powered, there would be no way

Some boats have the mast positioned in front of the pilot and almost amidship
forward of the rear planks, while other boats have the mast positioned behind
the pilot almost directly over the planks.

Other than being able to see the wing easier when it's in front of the pilot and
easier trim flap control, are there any other advantages of having the mast in
front rather than behind the pilot?

Other than having a clean unobstructed view forward when the mast is behind the
pilot, are there any other advantages or disadvantages in having the mast behind
the pilot?

Thanks!   I'll have to play with that so I can apply it in my next project.  Too
late for this one as I already have my steel.

Your comment made me dig a little deeper and it is NOT something I want to do.  
It sounds like TIG is the way to go (which I don't have).   MIG is too hot and
heat leaching after the weld will make the weld brittle.   To fix I read that
you can heat treat the weld with an oxy welder.   This is definiately outside my
