Corbie 5 IOM laser cut frames (updated)

I'm working my way toward building the Mirage Radio Yachts Corbie 5 IOM RC sailboat designed by Jeff Byerley in Tasmania.

I'm designing the Corbie 5 laser cut frames and planking forms, and have updated the frames that I initially made. I wanted to build in the few permanent frames that are needed.

There is a main bulkhead that divides the foredeck from the aft portion of the hull, there's the shroud chain blocks, a few foredeck support frames, foredeck kingplanks, fore and aft frames, etc...

I'm not done as I still need to include the rudder frame and the mainsheet post frames.

But I've made lots of progress and will now need to wait to complete the final version until after I receive the fin and rudder that I've ordered from Radio Sailing Shop in Australia.

This is how the model looks so far...

This first picture is of the permanent frames with the hull shell showing over it:




This is the same but floating in place over the building jig:


Here are just the permanent bits floating in place over the jig:


And here are all the frames that I will plank over, including both the temporary frames and the permanent frames. You can also see their support bases that are held in place with the building alignment jig. The thumb tacks in the side of the strongback are for additional rubber bands that you can run over the assembly to help with planking. The support bases already also have openings and hooks where you can use rubber bands:


More after I get my fin and rudder.




Aloha!

1934 America's Cup Rainbow J-Class RC Drawing

At some point I would very much like to model a vintage America's Cup yacht. The one I've been most interested in lately in the 1964 winner Constellation. But this past week I was sent a 1/16 scale drawing of the 1934 Rainbow. It's a beautiful drawing! Full sized so it's very large. I have been working on making it into a 3D model, but as is true with most hand-drawing lines, none of the lines from one view match up with the lines from the other views. For example, I spent a lot of time tracing the "sections" view so I could make stations. But when I tried to match them up with the plan/deck view or the waterplanes view, none of the lines met. Some came close, but all had to be adjusted. Then, once they are matched to the deck and keel lines, it's obvious that the hull is not fair. I honestly doubt that the hull would be fair if you simply used the station lines as originally drawn either. Back when they made these boats, they put it on the actual bu...

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 . Wil...

Made a Mast Crane

Made a mast crane based on one that I have made in the past for my Star 45's. Works well for them, and should work well for a Vintage Marblehead Sun Wind. It's made from brass, with a bar for strength soldered to the top. The idea is that a slot will be cut into the top 2" of the mast, and the crane will be through-bolted. This link is to the original schematic of a mast crane that you can build yourself, courtesy of the Miami Valley Model Yacht Club in Ohio.  Here is my updated version. Click to see the full-sized image and then copy and paste it into Word. It "should" print at just about the correct size, but you may have to adjust the image a bit. Cut it out and spray glue it to some brass sheet. Cut it out on a band-saw and then sand smooth. Be careful when working with tools and metals!! This is what I ended up with for my Sun Wind HF. I decided to reinforce the crane with a length of brass bar soldered to the top edge. Back to deck pl...

In the Works: "The Wooden IOM Construction Manual"

This is months away, if it ever actually gets completed, but I thought I'd try to get some input on what should be included in " The Wooden International One Metre Construction Manual " for building... get this... a wooden IOM. I'm over 60 pages so far, but it's good to get other ideas and input. This is the third RC sailboat construction manual I've written, and it's the most accurate. But it's also the one that I have the most anxiety about because I'm still a rookie in the IOM world and others are building such gorgeous boats. Unlike Star 45's and Vintage Marbleheads, which are great but not raced as much, IOM's are still very popular. And everyone has their idea of what's best. My goals though are to: 1) Help grow the class and help people get into what is a very competitive and rules-based class. It's a very tough class to fully understand and to compete in. I'm still learning the racing side of IOM's myself, but ...
