Wampum Finishing, Pt. 1 - Filler and Color Coats

The paint is on!


I began the finishing process (applying filler, paint, and varnish) by brushing on some two-part epoxy filler below the waterline. I'm using Interlux Primekote 404/414. Great stuff, but extremely smelly! Pretty expensive too. But it sands down wonderfully. It fills all the deep scratches and pits and such.

The filler goes on pretty thick, but you end up sanding most of it off. Keep in mind that I'm only putting it where paint will go. The topsides will stay natural. The pictures below are after sanding the filler off. 


It may look rough, but it's actually just filled the scratches and other low spots. It feels very smooth now.


Then I masked the boat. I'm making an accent stripe at the waterline. There will be one thin line of clear wood, and then another thin line of white above the waterline.



Next I mixed up some two-part Klass Kote epoxy paint. The first coat was clear. It's really only to act as a "bleed" coat that will seep under the tape. It's this coat that makes for a razor sharp line when the tape is removed. Then I followed with four coats of white. I thought that three coats would do, but the white needs to be reduced more than their other colors, so it just didn't cover entirely after three coats.


You can see some "orange peel", but it's not too bad this time. I'll lightly sand it before the varnish goes on and it should all disappear after five or six coats of varnish.






Oh... and don't forget to spray your rudder too!

Today I lightly sanded the entire hull and then sprayed on a few coats of clear. Here's how it looks.



These pics are after I then sanded the first clear coat and then sprayed on several more coats. Looks good now... the scratches that I could still see after the first round are now gone.

However, I'm not done. Next week, after this reaches "sward" hardness, I will spray on Klass Kote clear urethane. It's an experiment as I've never tried it before.




Klass Kote is good paint. You mix equal parts of the two parts and then let it sit for 30 minutes. After that you add one part or less of reducer (thinner). Mix that well and let it sit for a few minutes, then spray on a thin coat. Let that "flash off" (Let's the reducer evaporate out of the paint) for 20 minutes or so and then add a second coat.  Repeat as needed. Usually at least three coats are required.

Let the final coat sit for 30 minutes or so and then carefully remove the masking tape. You do not want to let epoxy paint cure with the tape still on or you'll never get it off.

Let cure for a few days. Klass Kote epoxy paint reaches "sward" hardness in 4 days to 1 week.

Part 2 will be my attempt at spraying clear urethane. I'm trying that this time instead of varnish. Stay tuned!



Aloha!

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…

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 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…

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 to accommodate the aft…
