Surfcowboy, are you still in Houston? If so, we should have a bump arrive this weekend and I have extra boards.

Oh man! Windwake thank you. I'm back in LA but should be back before too long. I'll hit you up. I also am dying to bring a foil as I think the Gulf is ripe for foiling. Tanker waves too since you shouldn't even need them to break so we may not have to chase them too badly or pick only certain spots. I'd love to meet up for a paddle when I'm back in town, even if it's just a flat one. ;)

Blackeye, you've sent me down a YouTube hole with the bladder thing now lol. Thx for that link. I'm watching all that guy's other vids now.

You guys said to put a big ugly fillet on this thing, right?



Itíll smooth out with a little sanding and then Iíll start laying on the final carbon layers.

Looks like a couple minutes with sandpaper on a round stick and you'll be golden.
I forgot to consider twisting loads from the wing to the fuselage. I may end up with a couple 'big ugly' fillets too.

Thatís classic cowboy!
Question: Could you have used the fiberglass rope that they use for glassed on fins instead? Can use fingers to mold it in place. Or would that not be strong enough for this application?

808, this was a weird one. Had I just used cabosil I'd have been able to make a small one and that would have been it. But since I used microballoons and it spread out, I just decided to fill it in and avoid all the sanding. It worked out but yes, it could have been about half the size.

I just need to smooth it a bit with some sanding and then I'll lay carbon over it. It'll be pretty bombproof at least. But it's gonna look like I have a Tuttle adapter on it lol.

Like all things with this build, the next one will be smaller  ;)

I'd recommend chopped carbon for stuff like this. It's surprisingly strong even though the filaments are not continuous. And of course there's nothing to buy, just chop up some carbon scrap and mix it with epoxy.

I add some milled fiber as well most of the time. Since I was covering this and wanted to sand it easy I went without here. Should be fine but it's crazy how much strength just those tiny fibers add.

I sanded this down, then filled and re-sanded smooth (pic coming, I'm having issues with Tapatalk.)

I've got the underside of the plate and the transition to the mast in the bag now. You know how you've got a good wife? She will help you get parts into the bag. You know when you have a really good wife? She knew to put peel ply on but didn't mention it and let me do what I was doing. Lol.

Probably losing a bag today but I know I married well. I also told her that I trust her enough that if she's sees me doing something goofier than usual to mention it. But minding your own business is a major part of staying married so God bless her.

If I have another bag, I'll try to get my mast layers on one night this week. It's light outside now after work so I've got no excuse to slack on my sanding. Pics coming soon.

Plate and fillet done. I'm having issues with Tapatalk so I can't upload right now. (Paging admin, I'm getting a server error.) I'm still blown away at the strength of plywood covered in carbon. Next one I build will have less wood I think now that I know the strength involved.

All I have left for glassing is to lay up the mast. Hoping to do that tomorrow, then it's off to Vegas for a week of work (Laird help me.) when I get back, hot coats and then finally, mounting the tail wing. Getting close boys.

Then, what next? ;)

Laid up the mast tonight. 3x 6oz carbon, 3x 4 oz glass over 2 x 6oz strips laid on at 45į Angle. Out of the bag, nut not yet hotcoated, it's 3 lbs, 3 oz. with the wing, it should all float.

Haven't tweaked on it due to it curing but it seems bulletproof. I'm super proud of this thing even if it never flies, it's been a great build and I learned a ton. Patience pays off for sure.

Me too. Tapatalk stopped working for me a while ago, but only with the standupzone. It says 'Server error'.  I just blew if off and open TheZone in a web browser on my phone.

Looking good Cowboy!
