Inner Sheer Rails installed

Only one job to be done tonight, and that is to install the inner sheer rails. I couldn't also install the stringers because the rubber bands that are clamping the inner sheer rails need to use the stringer notches.

The sheer rails are composed of two laminated strips on both sides of the hull where the hull meets the deck. The frames have notches for both the inner and outer sheer rails.

The idea is that you epoxy on the inner sheer rail to the notches on the frames one day and let it cure. Then the next day you run epoxy down the entire length of the inner sheer rail and then laminate on the outer sheer rail. It's the lamination of the two rails that adds so much strength to the hull. The lamination also permanently holds the two rails together in the proper curve.

Later on during planking, you will actually add, essentially, a third sheer rail when you laminate on the first plank.

In this first picture, you can see the inner sheer rails on Frame 0. They are held together by a rubber band wrapped around the two rails, and then run aft to the Frame 1 stringer notches, and then up and over the keel.

The darker strip of cedar in the picture is a piece that is run through the "king plank" notches in the deck frames. It is NOT glued in now, but is simply used as a way of centering Frame 0. It will be removed tomorrow.



In this image you can see that every frame has a rubber band holding the sheer rail in place while the epoxy cures.


Tomorrow I'll epoxy on the outer sheer rails and the two stringers.



Aloha!

Rip Tide RC Sailboat

Well I just hit the R/C Sailboat jackpot! Rod Carr, of Carr Sails in Redmond, WA, and the second ever member of the AMYA, just gifted me a Marblehead "Rip Tide" hull and many of the parts and templates to finish it! Thank you Rod!

I'm not sure when I'll be able to work on this, but hopefully it will turn into a fantastic vintage Marblehead. The gentleman who started it did a fantastic job. He was a true artist and I will do my best to get as close as I can to his workmanship but it will be a challenge.

Here are some pictures...


He even cast his own bulb and the mold came with the hull! I could probably start making my own fleet of Rip Tides as he also gave me many of the templates and such. I will only need to pin and epoxy the bulb to the fin and fair it smooth. It will be easy to do.


The frames look and feel like he hand cut them on a scroll saw, but they are very close to perfect. He used thicker plywood than I may have but they are very sturdy. The bow is very s…

IOM Rig Box (IOM Sail Box) plans

So all the cool IOM kids seem to have nice wooden boxes to store their rigs in. This might be my next quick project then, so that I can pretend to be cool too. :-P

The rig box images that I've seen online are mostly similar, and would work well, but David Jensen from Bellevue, WA, USA (The same guy who designed a fantastic IOM boat stand I posted about earlier) has a really nice design that he shared on RC Groups. Or if that link doesn't work, the go here and search for "IOM sail box" or "IOM rig box".

It holds three sets of rigs for the A, B, and C rigs.


He also has a nifty way to attach his IOM boat stand, with a boat on it, to the rig box. His rig box has wheels attached, so once everything is loaded up he just wheels it to the launch spot. Very nice!



There are other sources online. They show different variations of the same type of sail box.

Here's a nice looking one.

Here's a YouTube video of a really nice one.

Will post more if I actually end…

R/C Sailboat Builds

Here are the other boats I've built in the past few years:


1. A Tippecanoe T37. These are kits available from Tippecanoe Boats in Washington State.








2. A classic, wooden, Star 45. It has been officially measured and is class legal. The Star 45 is a pretty, classy, builders boat that has withstood the test of time.







3. A Salish 475. It's my own variation on the Star 45. It was built from the same laser cut frames as the Star with a number of modifications aft of frame 6. It is an update of the classic look and was an attempt to mimic a modern ocean racing yacht.










I've also built four Pygmy kayaks and many other projects. It's all fun... right?!


Aloha!

IOM Sailboat Stand

I made an IOM boat stand!



The plans are from David Jensen in Bellevue, WA, USA. I found the plans through someone else's blog here, and a model sailboat club from Australia here.

It was pretty straightforward to build. My only contribution to the design is that I laser cut the cradle out of 1/8" Lite Ply. I made eight copies, and then epoxy laminated two sets of four each. Turned out really well.



If you wish to laser cut your own set, here is my DWG file. You'll have to have your own laser cutter, or send the job to a laser cutting company like National Balsa. Here are the original plans, and here are the original plans for just the cradle. Thanks to David Jensen!!

Note that in the picture below, my boat is not finished! Yikes.


You can't see it in this image, but there's a small chuck of self-stick foam behind the bulb to protect the bulb. I'll eventually incorporate some Velcro or a strap of some sort to hold the bulb in place so that I can use the carry-han…
