Thanks. Will work on the main again tonight. Visiting my mom right now. Kookaburra II looks great too.

Well, a man cold slowed me down today. I have got a fever all day, and only did a few things to the boat. I did manufacture a toggle for the forestay.

I taped the jib to the mast, for it to "un roll". Will hopefully install the jib tomorrow if I feel better.

I hope to work on the boat some more this weekend. I have been down with the flue all week...
Not complaining, it's not cancer, but it does put a hault on the stuff you enjoy doing.

Worked on the jib sheet system today. I used a 2.4mm stainless steel welding rod as a self tacking jib rail.

It feels a little bit flimsy, but the posts I used (also stainless) can be drilled to 3mm dia.

I think it will hold, since the main force will be when the jib sheet is close to the posts.
I positioned the rail as close to the mast as I could, for the jib to be as large as it can be, mainly for looks.

Sorry for bad picture. You get the drift. The room has poor lighting and it's dark now.

The two round washers underneath the posts are hand made from 1mm stainless steel... No lathe used...
I used my belt sander and grind them down to a circle. Two little pieces took a good hour and a half (time to figure out how to make them).

When I used to have access to a prototype shop at the old factory, those two pieces would have taken five minutes to make...

I started working on a 3D drawing of a sail mold today. The idea behind this is to build a sail mold that I can use to produce radial cut sails for Australia II.

I will test build this. The "mold" will be 2400mm long and 900mm wide at the base.
If it works, I will be happy to share the drawings with you guys. I'm not being too scientific about the design. I use my eye and what I think works.

Worked on the jib today. Will post pictures tomorrow. Might even test sail the boat tomorrow. It all depends on how much wind we will get.
It was super windy today.

First test sail today!
Everything went pretty good. Fore stay came loose and was fixed with some white electrical tape. I will change the design to prevent this from happening again. The boat sailed in good balance. I will work on the jib sheet arrangement some more.

All in all a great first test sail. The boat is a little bit bow heavy, and I will remove 300-400 grams from the front of the keel.

Thanks!
It is getting there. By no means perfect yet. Not having a jib boom is a first for me, and the test sail was not 100% a success.
I'm happy with how it performed, but there are things to improve.
A bit bow heavy will be fixed tomorrow morning. I hope to sail again tomorrow if the weather permits.

Thanks,

Lars

Hello Troy,

I have updated the jib sheet system, and will fix the fore stay attachment tonight. I plan to sail the boat again tomorrow.
I have also put in a 2 Cell lipo instead of the 5 cell NiMH that I was using during the first test sail.
The boat also needs the graphics (still waiting) and a new coat of paint on the deck. I hope to make a mold in the fall.

I will keep posting pictures and keep you guys updated.

I took a day of vacation today. The weather is absolutely fantastic. I went sailing with my nephew this afternoon. The sheeting system worked a lot better today. I still have some to do some mods to make it work perfectly.

I wish everyone a great weekend!
