- It is a toy, not a scale model. I want to keep it simple and relatively easy to build. (Which also means easy to repair. It will probably see some rough play.)
- I want to keep it close to the scale of the British tank.
- The guns are the center point of this toy and we need to come up with a way where all are present and can move in some sort of way
- A clacking noise as it is pushed would be nice.
I'm using a 2x3 as the "hull" of my toy. It will be the center of the toy with everything attached to it in some manner. When the toy is finished, very little of the hull will actually show. The front and back of the tank will be about 1/2" thick so that leaves six inches for the hull. I traced the pattern on the block and marked the machine gun locations. The hull is taller than it needs to be here. Ultimately it will only be 1 5/8" from its highest point to the bottom. The cupola will be added later.
I marked out the locations for the main gun and each of the machine guns based on the pattern. I used a 1/2" forstner bit for the machine guns and a 3/4" one for the main gun. I made sure that I cut the holes to be deep enough so that they can securely hold a dowel the same diameter that will serve as the swivel for the guns. (Trust me; it will make sense in a minute.)
I'm finally getting smart about these things and have realized that it makes sense to work on a couple of toys of the same kind at the same time. Most of the time in toy making is spent in setting up cuts as opposed to actually making the cuts. Here are two hulls (creatively labeled "1" and "2") with their top holes drilled. Hull #1 already has the front and back slope cut. Honestly, I jumped the gun (so to speak) on that one and could have waited until the next step was done.
In another live and learn moment, I cut a 10 degree bevel along both sides of the top of the hull before drilling the side holes that will allow the guns to stick out. The bevel is so that the armor sides will hang at the proper angle and give the tank the correct shape. Not really a problem, but next time, I'll drill the holes first. These holes are the same diameter as the as their respective gun mount dowels and are centered on where the guns will poke through the armor plate sides.
The next steps are easy. Just pop a dowel of the appropriate width into the opening and mark where the gun should be centered and where the top of the dowel needs to be cut so that it will not protrude above the top of the hull. Before you cut the dowel to length, drill a hole into it that will hold the dowel that will be the guns. (I used 3/16" for the machine guns and 1/4" for the main gun.)
