Introduction: Sailboat to Ukulele

Picture of Sailboat to Ukulele

In 2006 my son and I each built a skiff /sailboat from plans by Iain Oughtred a great father and son project.

unfortunately that fall while on the trailer in the back yard a large tree limb fell on my sons boat taking out most of one side. He thought that maybe he would repair it but never got the time. After several years it ended up in the pasture with trees growing out of it.

So after years of thinking of those beautiful mahogany seats I talked him out of one them. For his birthday I cut it for a custom ukulele.

Step 1: The Seat

Picture of The Seat

The front seat you can see in the photo the hole is where the mast for the sail went through. I was thinking I would make the sound rosette out of leather like the leather mast protector but n the end it didn't work out. I used a table saw to cut the 3/4" thick mahogany to 1 piece 22x4 and 2 pieces 13x6 then re sawed each to a book matched 1/4" thick 1 back 1 side and 2 sides also I joined the 2 pieces of the top and 2 pieces of the back. After joining the plates I surface sanded them with a drum sander to .07 thick sides .10 for the back and .08 top

Step 2: The Bender

Picture of The Bender

The side bender I use I made Its a fox style with 2- 200 watt light bulbs heating up sheet metal formed around ukulele shaped sides held in shape by clamps it works great and was cheap to build about $30.00

Step 3: The Plan

Picture of The Plan

I got this tenor ukulele plan from Stewart McDonald it seems to be a good one. I had it copied it several times to cut up for templates it has worked well for me

Step 4: The Mold

Picture of The Mold

The mold is 2 pieces each 1/2 the uke. using the plan as a template I cut the 3/4 plywood and triple stacked it and glued it together one half at a time leaving the two sides separate this lets the mold to split for marking plates and getting the completed body out of the mold, I then clamped the mold together and drilled a 1" dowel at each end to make for easy line up.

Where the 2 pieces join is also used as a center line through out the build (very important)

Step 5: Bending the Sides

Picture of Bending the Sides

First turn the bulbs in the bender on for about an hour while soaking the sides in water for 10 minuets drip a little water on the metal form if it steams its hot enough. I've never gotten it too hot with this bender but I do have A variable resister on it if I need it. I place the wet wood in side by side. Place a piece of spring metal over the and slowly clamp the waist down. Then start bending the upper and lower bouts anclamping in place. It takes about 15 minuets to bend the set. After bending I turn off and leave in the mold over night.

Step 6: Compleat the Rim

After sitting in the sides will hold the shape when removed. Next clamp in the mold and mark the center lines and carefully trim away excess. Glue the end and neck blocks staying on center line. Next clamp on the kerf lining a little proud of the sides.

Step 7: The Back and Sides

Picture of The Back and Sides

After joining the top

and back and thickness sanding I first cut the sound hole. I would normally cut in the rosette but as I said I was going to use leather for it so I left out this step.Basically following the bracing pattern from the plans. Using small planes and braces and tone bars tune up the braces and tone bars fin tuning with sandpaper.

Step 8: Closing Up the Box

After sanding the kerf lining and blocks down flat with the sides I use a radius dish covered with sandpaper to put a 15 foot radius on the back. The back and top are then glued on. Then I use a router to flush trim to the sides.

Step 9: The Neck

Picture of The Neck

The neck is made from 2 pieces of the mahogany seat and a walnut center. This laminated wood makes for a very stable neck. I use templates mad from the plans to rough shape and then use sanders, planes, rasps and chisels to shape. Then I glue on the head plate and fret board and finish up the neck.

Step 10: Inlay

Picture of Inlay

The design of the headplate I kind of got from a lot of different pictures of the Internet, I had to have a sail boat you know.
The moon is yellow mother of pearl and the sails are white MOP.
I used a jewelers saw to cut the shape and sanded true. Then with a detail router to rout out the cavity's
after gluing the pearl in I mixed ebony sand dust with yellow to make a filler paste to fill in any gaps.

the boat is a pies of the seat also.

Step 11: The Neck Joint

Picture of The Neck Joint

I used a bolt on neck joint to attach the neck to the body. After dry fitting the joint I used a brass insert drilled into the heel of the neck and a bolt through the body. No glue is needed and makes a very stable joint.

Step 12: Binding the Body

Picture of Binding the Body

I bound this ukulele with curley koa binding top and back and used black whiwt black purffling on the top only.

I use a router with a straight bit and bearing set up for my binding channel. The first bearing leaves a channel that is wide enough for the binding and and pruffling as deep as the purffling and the second cut is as wide as the binding as deep as the binding. Does that make scene? I'm tired! The channel on the back is just for binding no purffling. After routing and cleaning up the pre bent binding is glued in taped down until the glue dries. I use a cabinet scrapper to clean up and sand flat

This is to me one of the most difficult part of the build because things could go very wrong very fast.This one went well ,best iv'e done so far. I think I came up with just the right router set up.

Step 13: The Finish

Picture of The Finish

The finish I used on his ukulele is nitrocellulose lacquer. I finish the neck and the body separately it is much easier to sand and join after polishing. With the parts sanded to 220 grit I fill the pours with epoxy sand to 400 and spray with sealer sand to 400 and spray 3 coats nitrocellulose lacquer let dry over night. Next I wet sand to 400 grit to level out finish. After sanding it down dull I can see shinny spots these are low places. I repeat the spray/sand process untill all the shinny spots are gone and everything is dull 12 coats on this one. after 3 days I thin the nitrocellulose lacquer and spray 3 more coats and wait 2 weeks then sand to 5000 grit. Next I buff out the finish and join the neck to the body.

Step 14: Fret Board and Bridge

Picture of Fret Board and Bridge

The fret board is ebony I used a luthiers miter box, template and fret saw to make it. I also added mother of pearl dots and plastic sides.

Step 15: Putting It Together

Picture of Putting It Together

After bolting the neck on I glued the bridge on and set up with a bone nut and saddle strings,tuners and a little tinkering its ready to go. I love the way it sounds and plays This is my 5th ukulele build this on turned out great ill try to put a video up soon.Thanks for viewing Ricky Sp8

Do you know where I could find the blueprints for this project?

sodasonic (author)2015-10-27

great work! thanks!

At first I thought you had done something like the Maton Boat but I see I was wrong - but not disappointed. That is one beautiful ukulele.

Might I say that boat looks good too. It gave me a sad to see a boat so nice not being repaired.. If a boat does have to be broken up rather than repaired then being turned in to ukuleles is a fine way to go.

rickysp8 (author)titchtheclown2015-08-02

Haha!! Very funny. thanks

It would have been neat if you could have kept the mast hole to be the sound hole. The star pattern of the nails from the leather mast partner would have been a neat way to tell the story of the origin of the wood.

Iain has some wonderful designs. I'm glad that one of the two survived and is in use. Have you thought of emailing Iain pictures of your transformation?

rickysp8 (author)Jobar0072015-07-27

Thanks i tried to keep the mast hope but couldn't get the sides out of the board. I cut some leather to make a star but couldn't get it right.
Email lain ? Not sure who that is
Thanks for the comment Ricky

Jobar007 (author)rickysp82015-07-28

Iain Oughtred, the designer of the boats that you and your son built. I think that it would be a neat story that he might enjoy. I know I would if I were him.

rickysp8 (author)Jobar0072015-07-28

Good idea I will thanks

NathanSellers (author)2015-07-27

This is so awesome and meaningful. The inlay is beautiful.

rickysp8 (author)NathanSellers2015-07-28

Lemonader (author)2015-07-27

this is such a cool project. And recycling!

rickysp8 (author)Lemonader2015-07-28

thanks I love to recycle

Jack Moran (author)2015-07-26

What exactly are the red and green objects covering the sound hole when you were applying the lacquer?

rickysp8 (author)Jack Moran2015-07-26

those are balloons they keep the lacquer out of the inside but most important they keep any dust on the inside from being blown out into the finish

Jack Moran (author)rickysp82015-07-26

Thats a great idea! Thanks for the tip! Love all your i'bles!

annrrr (author)2015-07-25

Another great uke! Can you share more about your side bending apparatus?

rickysp8 (author)annrrr2015-07-26

thanks I didn't take pictures of the build process to share but I'll try to take some thanks Ricky

BossyRangs (author)2015-07-25

Excellent craftsmanship! Will remember this Instructable if I ever decide to give it a try myself. The opposite would even be more impressive: ukuleles to sailboat :-)

rickysp8 (author)BossyRangs2015-07-26

thank you there fun to build

Edbed (author)2015-07-25

Great instructable. The uke looks great.

rickysp8 (author)Edbed2015-07-26

thank you , Ricky

calexander18 (author)2015-07-25

This is one of those instructables that I just love reading. I don't have to skill to pull this off, but just seeing the process and your craftsmanship is incredible. You've built something beautiful.

rickysp8 (author)calexander182015-07-26

thank you nice Comment

script_coded (author)2015-07-25

How did he like the ukelele?

rickysp8 (author)script_coded2015-07-26

thanks for the great comment he liked it I called him the other day and heard him in the background strumming it.

script_coded (author)2015-07-25

From boat to ukelele?! Waw! Really incredible! At first I misunderstood the pictures. Thought you made a boat from an ukelele, because it looks like a high quality one from a musician store. As said. Really awesome!
