Rick, As noted many times, you are encouraged to post here.  As with all brand associated individuals, branded content is what is not allowed.  Thanks!

If we want to push lift forward we can always add forward sweep, pictured at 1140 here with some compound sharklets to combat vortices and a root/connector well which is "under construction".  With a well design like this we could use both vertical and horizontal mast attachment hardware simultaneously.

Here is the center portion of a another concept wing.  It also presents the mount junction for the mast integrated into the front wing.  Axis Carbon Mast). This one is  987 mm using a different cambered section with a symmetrical root section (1 inch transition).  Incidence at 2.5 degrees.  Sections can be printed solid as shown or with any wall thickness/infill combination and can be sliced at any width shape or dimension.  Hybrid solid/infill configs are also possible.  Sections can be bonded and laminated or printed as one and laminated.  The result is a light and strong all carbon core and a carbon prepreg exo.  Lots of experimentation will required to achieve the optimal weight to strength balance.  So stoked to have these amazing technologies and materials available!

As a side study (not applicable to this direct mount idea), here is the Axis red fuse head at scale nested into this downloaded segment (which has been scaled to a chord length of 7.5 inches and set at an incidence of 2.5 degrees).  Interesting to me as it shows how much depth would need to be added for mounting material below the head for this segment and head at this size and also how little profiling would need to be done to match the surfaces.

What am I thinking?  We can do a gravity sketch shared session.  My wifi sucks, but Carson plays Among Us VR all the time with a group of screaming 7 year olds, so we should be fine.  PM me your best email address and I will send you an invite.

Shit, I'm still floating around like a vampire in a blank room trying to figure out which button does which. I can't get the dimension and axis lines to appear with regularity. Holding one controller under the other makes different kinds of lines in what seems to be a completely random way.

We can do a call any time and I can get you over the hump.

A few things that help. 

General - turn off face tracking and eye tracking.  Battery will go from 2 to 4 hours and you lose nothing.
Turn on "world axis" in settings.  I keep that on always.  That will show the red, green blue XYZ axes (axis's, axis', axe-ease - I give up).
To measure anything, go to primitive shapes in the tool menu and select the little right left arrow icon over to the right.  That will enable the measurement tool.  You can change from metric to imperial in settings.
Smart move is important.  Check this out:

Looks awesome. Not sure how you are actually designing the foils but this might be of interest.

I am taking attractive foil sections from the database and I am taking care to preserve the section shape exactly for the length of the foil.  The only exception is the center where I have made that same shape symmetrical (It is naturally cambered).  I did that for extra support and flow at the mast union.  It flows from symmetrical to cambered in about an inch.

Hi Guys,

I advanced this a bit today.  Removed some overkill loops, added some backsweep, subtle gull, and 2.5 degrees of progressive washout/flare at the tips from the visible control loop.  The fuse is a placeholder.  I am not sure exactly what Bill has in mind, but I like it.  My thought is that we can test and reduce until flex causes problems.  Some internal views (that is so fun) and measurements as well.  The wing is actually quite thin and high aspect.  It remains a work in progress.  I haven't done the wingtips yet.

Thanks dude.  I could only find small ovens or huge walk in stuff in the US and no small ones with internal pump attachments or any kind of pump control.  I was actually surprised by the reasonable oven price, so even with shipping it seems like a great value.  The prepreg is expensive so anything I can do to eliminate mistake waste is probably worth it.  The cure cycles are pretty exacting and I don't want to manually nurse temp ramps and the likes.

Man, was that a quick 5 years!  Today is the anniversary of my birth as a crappy guitar player.  To celebrate, here is my suitably obnoxious go at Hey Joe (with a few throw-ins).  Not a cover, cuz who would do that 🙂 ?  First a few passes through the basic rhythm and then a few runs through some lead.  Brace your eardrums!!

SUP has run its course. Now it is just another way to surf. It was the novelty and innovation that lead me to SUP in 2013. A decade later, it has all been said. There is nothing left to talk about or think about with paddleboarding.

Foiling has rekindled the stoke I had in the early days of SUP and the early days of windsurfing, snowboarding, and mountain biking. Some people can keep doing one sport their entire lives and that's fine, but I have to keep moving. When the innovation ends, I'm on to the next thing.


Run its course? I still forget most of you guys think sup means surfing. That does explain why this is all foil lately - you are surfers and that side is less interesting. But the adventure paddle thread has cleared 100,000 views and that counts for something. It's just not centered here on this site. Karl Kruger is paddling the Northwest Passage..... Alone. People are paddling around entire remote islands in the Salish Sea - territory that was exclusive to experienced kayakers and bigger power boats before. It's just not happening HERE and you are only seeing the edges of... whatever standup-sea-kayak/adventure-sup is.... and that's OK.

Deep, I read each one of your posts and I travel with you.  Same goes for the guys posting surf videos, downwind stuff, etc.  Being less actively involved in something doesn't mean disinterested or disowned.  The Zone is still here for SUP.

Those clips look fantastic.  Thanks!  I am getting those for sure. 

Tarquin, this was the best (really only suitable) prepreg oven I could find.  I love that it controls the pump (or two) and controls the cure cycles.  This is going to be fiddly enough so whatever I can automate, I am down with.  Do you know of an alternate or a local reseller for their oven and products?  I would be open to that for sure.  Once I am having the oven crated and shipped, the rest hardly changed the price.

Easy is claiming a specific prepreg for the out of autoclave process, which they say produces a cleaner finish.  I know, excellent marketing, but I thought I would start with as close to a known good process end to end before I start making the inevitable substitutions.  That way, when things go sideways, I will have less possible reasons (and will have a resource to email a pic to).  Their tech support guys are awesome, friendly and are as informative as their videos.

Their variable rate prepreg looks like an awesome option.  They wrote "This prepreg is vacuum-bag, platen press, and autoclave compatible".  I sent a question about this to see how they fare with this out of autoclave process.  Red or blue foils would be rad (although the colors need a little more heat).

Nice.  I ordered the oven with all the goodies, the EC4 pump (they claim mist free - We'll see), those cool quick connectors for everything, and a ton of the consumables.  No prepreg yet.  I am waiting on the printer.  I am going to take your advice and get a freezer and I will look for one with a thermostat. 

We are going to have a lot of fun with this.

Cool!  Let's try those things.  I ordered rolls of all of the prepreg bagging consumables including the tube bags so we can experiment with all kinds of SHO's (stabilizer holder outers).   We are not really limited in the wing designs that we can do this way.  Check out this image.  This is the Axis advance fuse and the normal.  They are at scale.  On this first (rough) model, I put the mast just a bit forward of the advance, but we could easily move the mast back to even behind the standard.  We don't need to introduce any pitch issues (unless we want to).  The other pic is how I grabbed the rough mast shape and then scaled that in.  We can likely do that part as a regular mold when we bag so this is just for visualization.
