Wampum VM Ballast Installed and Faired

This week has been busy with life, but I've also been able to get a bit of boat time in.

I've installed the ballast and started the fairing process.

First, I cut the boat free from the building board, and then did a number of float tests with the lead simply pinned in place. Ended up using a bolt cutter to trim off some lead from the aft ends of the ballasts.

Then I installed the lead onto the keel with thickened epoxy. When that dried, I then drilled several 9/64" holes all the way through the two halves. The holes were filled with short pieces of 1/8" stainless steel rod, and then thickened epoxy was piped in with a syringe. The lead is now epoxied and pinned permanently.

Then the fairing started. I'm using a variety of thickeners. For strong adhesion, I used phenolic powder to stick the lead to the keel. I've had good luck with it in the past. It's the reddish stuff you can see. But then I'm experimenting with silica. It's the whitish stuff. It makes a very light filler, and seems to sand easily enough yet still be strong.

Unlike WEST System 410, these other two fillers don't need a coat of epoxy on top of it. I've got some 410 and have used it in a few places, but I'm not convinced it's the best to use. I'm liking the 406/Silica stuff better. My silica is from System Three though.

Here is after the first coat of filler. Pretty rough, but it's only supposed to "fill" stuff. The finer coats come after. 

Here's the second coat after I sanded the first coat. The garboard is starting to get filled and rounded.

I'm two coats of fairing compound into it now, and probably have another two to go. So far it's looking better! By the time I put a coat of Interlux filler on it, it will look like perfectly molded plastic! Then it will be painted and look great.

More later!

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

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

A Wooden "Alternative" IOM RC Sailboat

Being forced to stay home due to the Coronavirus quarantine has had a positive impact on my boat building. I still haven't been able to sail my newly completed Vickers V8 IOM, yet have just planked and glassed a wooden Alternative IOM . It only took me eight days. It usually takes a couple weeks. I haven't been motivated to blog about it, but I started planking on 5 April and finished planking last night. Today I sanded and have fiberglassed the outside. The Alternative by Brad Gibson was a challenge to plank due to its up-swept bow and flared sheer near the bow. It turned out okay, but as any builder will tell you, there are goofs all over. One that I only discovered after sanding is a lighter colored plank on the starboard side. It really showed up after fiberglassing as the epoxy brought it out... GAAAAH! How did that get there? The other goofs I'll let you find, but that one is pretty obvious. Here's how it looks so far: Here you can see that mu

IOM Alignment and Measuring Jig (UPDATED)

I need to start to consider how I'll mount the fin and bulb, and get it all straight, so I made a 3D modeled alignment jig: Ian Dundas in Scottland sent me pictures of his setup. I just bought a laser level too! He does amazing work and has been a great help in this project so far. There is also another jig featured on page 14 of the winter 2008 Canadian Radio Yacht Association (CRYA) newsletter that features one. It's by Lawire Neish. Read it here . I took both those designs and made my own version that features sliding cradles for the hull, a fixed waterline sight, proper depth to cradles for the bulb, etc... Most of the parts can be laser cut, and the two end pieces and the base can easily be cut on a tablesaw. It has fixed waterline sights that are 420mm above the top edges of the bulb sliders in the base. The fore and aft cradles can be slid up and down to adjust the waterline of the hull. You'll see that the overall interior length is 1003mm t
