Finishing, part 6 - Varnish

Today I did the first coat of thinned varnish on the hull.

Over the past four days, I've let the hull cure and harden. It then sanded quite easily. For the most part, I didn't completely remove the orange peel but just flattened it a bit. The varnish should take care of the rest of it after 5 or 6 coats.

Then wiped it down with mineral spirits.

I'm using Pettit's Z-Spar Captain's Ultra-Clear Varnish. The can says that thinning usually isn't needed, but I added some mineral spirits regardless. Will probably do so for the first two or three coats.

While I've always claimed that varnishing is a dark art practiced by masochists, it does have it's benefits. It can hide a ton of flaws; scratches, slight orange peel, etc... Once it's built up, it can look fantastic.

I'm part of the "roll and tip" school of thought for varnish. The idea is that you use a small, 4" disposable foam roller to roll on a thin coat, then you go back over it with a disposable foam brush to even it out and to get rid of the bubbles. Generally it's the method that I've had the most luck with.

If you wish, you can do the "wipe on and then tip" method where you use an old t-shirt to wipe on the varnish in a very thin coat, and then use the foam brush to tip it.

Either way, the idea is to get a thin layer down that won't run, drip, sag, or curtain.

Here's how it looks after the first thinned coat...

Oh, and for those of you who died a bit on the inside when you saw that I'm varnishing in a carpeted room, get over it. It's less dusty than my garage right now, and is a room that gets very little use so the dust won't get kicked up too much. I'll probably clean out my garage very well and then do the last coat or two there after the dust settles. But for now, the TV room will have to do.

I screwed up while sanding the rudder the other day, and cut right through to the white epoxy filler underneath... ugh! So today I sprayed on another couple coats of Klass Kote "tile red" and it looks good. In a few days I'll probably just barely touch it with sandpaper and then start varnishing it too.

UPDATE: Four days later, here is how it looked after four coats of varnish... lightly sanding between coats.

Riptide 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 "Riptide" 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 Riptides 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 squ…

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?!

Sun Wind RC Sailboat 3D Model

One of my current projects is to 3D model Gus Lassel's 1949 "Sun Wind" Vintage Marblehead (VM) sailboat. Apparently it was originally called the "Sun Daze", as in fun sailing on Sundays, according to Adrian Olson whose father had a connection to the original designer. (By the way, check out Adrian's other model yachts too. He does beautiful work!)

Boats back then were free-sailing or vane-sailing. I think this was a free-sailing boat but am not sure. My version will be modified for RC. All I have to go by is an old set of lines, but hopefully I can get a decent model out of it. Eventually I would like to make laser-cut frames from my 3D model and actually recreate the boat in RC.

Adrian Olson offers a modern fiberglass kit for the Sun Wind. The pictures look beautiful! My intention is to create frames so that a builder can make their own wood & fiberglass version. I really doubt that many people will want to go through the effort it can take to make a …

Vintage Marblehead Riptide electronic files

UPDATE: As of 12/8/2017, I was sent a much better TIFF file of the original plans by Ted Houk. See my updated post

When Rod Carr gifted to me an unfinished wooden Riptide hull, it came with a CD of files from the gentleman (a man named Roger, I believe) who made it. I finally got a chance to look at the files and what a great discovery!

Roger created not only several very helpful PDF files, but .dxf files too. With some work I could make files for laser cut frames, fin and rudder!

NOTE: I am not the creator of these files and cannot vouch for the accuracy of them. The creator of the electronic files is unknown but the original plans for the Riptide go back to 1949 and are most likely in the public domain. One version of the Riptide lines is being freely distributed. These files are the only ones I've seen other than the original 1949 hand-drawn lines. I put them here under an assumed Creative Commons license for NON-commercial work. You are free to make your own Riptide but only…
