     Build log

I use to have a vehicle that I could carry my models in and be inside. But as time has gone on, I now only have small pickup trucks and the boats are too big to put inside the cab. So to be able to take my boats with me I had to come up with something.

So I built a transportation box out of wood. 
Here is a photo of my George Washington at the Fun Run in April. Not only does the boat fit snuggle in the box with foam padding, the top of the box has two supports that are hinged so I can place the boat on top of the box while on display or working on it.  (If you have been following the Skipjack build, you've seem the hull on this box top.
 

I have reached a point in the Skipjack build that I need to do other things while I collect and make arrangements to use a lathe to turn end cap for the cylinder. 

I thought I would show you what I do to make these boxes.
====================================
For the Skipjack, I decided I needed a box that was 12" tall. 6.5" wide and 46" long overall. This should give me a minimum of 1" clearance on all sides from the hull.. More in some places. I want to use a minimum of 1" thick foam for protection.

1. I went to the lumber yard and got two 8' lengths of 4"x1"x8' pine. 
I looked and picked straight and as clear of knots as I could find in the pile. 
I got (had) a 4'x8' piece of good grain door skin. It's about 3/16" thick plywood. 

2. Got home and cut the 8' lengths of pine  in to 4" lengths for easier handling. 
I need two pieces for the bottom. 
The rest I cut in to 1/4" strips. 
 


Bottom being glued together to make the 6.5" need. Will be cut to size after it cures.

3. I cut the door skin in to 
two 12"x48" pieces.  (long sides)
two 12"x6.5" pieces.  (short sides)
one 6.5"x47" piece. (top)
 

Once the bottom is cured and cut to size, the sides will be fit and assembled.

The assembly has started.

This is so Matt can see the cut using a combination carbide 10" table saw.
This is door skin. Wood on one side and primered on the other side.

Top started. Inside frame is together with panel in place and glue is curing. 
Trim frame will be started this evening unless the thunder storms come again. 

THe top fits inside the box with the trim overlapping the edge. I don't want stress placed on the trim so I mounted inside support ledges.

A 12" long piece in the middle of the long sides and a full piece at each end. The top will sit on these ledges but I will also fit the top so the trim just comes in contact with the box edge.

Looking at End edge in place.


Half the top trim being put in place. The top edge of the box has packing tape over it to keep glue from bonding with the box. 

Today, sanding on the putty. 
Just filling in the places the wood did not meet up flush. I'm not wood worker. 

Made the two stands that go on top of the box. 
Set them in place to take a look. 
Did some measuring so the boat will sit level on the stand.
Had to cut 1/4" of the bottom of the front stand. It was easier than taking off 1/4" in the rear stand which would have been a circular cut. 
The front was a straight cut. Yep, that's the one I did.

Painting has started.

Lid and Stand.

I got outside to do some more painting. 
It is such a nice day that I not only got more done, I finished it. 
So here are the progression photos.

The transportation box sitting on the metal work with the bottom up.


Painting (primer is the finish paint) the bottom and the ends.

Painting the trim edges that are up. 

Finishing the sides.

I painted the inside with the box standing on end. 
Didn't get a photo. 
Worried that the box might get blown over if the wind came up.
It didn't come up so I continued painting. 

Box and lid finished. 
Hull stand mounted in place and down.


Showing stand raised. 
There will be a very small bungie cord on hooks to hold the stands up.

Box and lid are both back in the shop to dry completely.
Got to go through tool shed cabinets to find a couple of hooks or eye screws for the bungies to hook to. 

The eye bolts are in.
The blind nuts are in.
The knurl knobs have been made and cut to length.

The lower rudders isn't in place because I have not yet shortened the rudder shafts to length. 
Can't put both in at same time until I cut the shafts to fit the control yoke.

I still have to cut dense foam to put inside the box to protect the model bow and stern. 
I will be giving the paint a couple of days drying time. 
I have in the past put the foam in a completed box only to have the paint fumes destroy the foam. 

Here is the new Skipjack box behind the George Washington box.

I took the time this morning to make the foam inserts that will hold the boat in place during travel.
The lower pieces are cut just 1/4" below the hull center line.
These will be glued in to the box so they will not move. 

Here are the top pieces cut to form around the hull.
They are about 1/4" taller than the box so when the top is put in place there is compression on the foam and the hull.
In this photo, the center top piece still needs a little more fitting done so it sits tight on the bottom foam pieces.

Yes, I test fitted the pieces in the box before making the hull cuts in the foam.
The notches in the top pieces are to allow the box top frame to sit on the foam with slight compression.

Lid removed exposing the boat with t he foam blocks holding it in place.
3 - 2" thick pieces supporting the boat with 2" thick pieces at the bow and stern.
The prop is placed in to the box first so the prop cone can embed into the foam.
The foam for the bow is removed and put in place by compressing the foam about 1/2".
When released, the foam pushes on the bow of the boat keeping the boat firmly in place. 

The top half of the three foam blocks removed.
You will notice the foam blocks have the top corners cut out.
This allows the lid frame to slip past the foam block and press down on the foam.
When the lid is put in place the foam holds the lid up about 1/4" requiring me to put pressure on the lid to insert the brass bolts that hold the lid on.

Look inside box with top foam blocks removed.

Boat removed and sitting on lid stand.

Side view.

I will be making two nylon straps that will be complete circles for carrying the box.
There will be two grommets place in each strap that will line up with the lid brass bolts. 
This will give me handles or a shoulder strap to carry the box. 
I can also use the straps to launch and recover the boat from the water.

The box project is complete at this point.
The basic box can be made to any size to fit your specific project.
I have less than $15 in materials in it, less the straps.
