Building Circle with Circular Bricks…

We’ve talked about a few circle building techniques. But the most obvious way is, as expected, to use existing circular bricks. You might think that the choices will be limited, but in fact you can do quite a bit with these. Personally I think that brick-built circles are generally good for circles with diameter larger than 8 studs. Circular bricks are generally good for circles with diameter smaller than 4 studs. For 4-8 studs, it depends on what you are trying to build.

Let’s start with the circular plates. These circles are perfectly circular. You can’t achieve it with any other techniques.

If you don’t want studs, here are your tile options.

If you want cylinders, here are your brick options. Technic connector can be used as cylinder too.

If you don’t mind (or want) a bit of curvature, dishes are your friend. (The 9×9 Hero Factory shield can be treated as a dish too.)

These are all of the obvious parts. Below are some of the not so obvious parts. First up are wheels. Wheels generally don’t have an integer diameter in studs. But when you add tires of different thickness, some have integer diameters. The different tire and wheel sizes are too much to document here. Here are some examples. Diameter in studs listed below.

>2
<4
<6

 

 

 

 

The next batch are more interesting, because they do have integer diameters and so can be used together with round bricks more easily. More importantly, they have a diameter of 3 studs. 3×3 studs plate, brick or tile does not exist. These bricks below fill this crucial gap. The last piece is 3×3 on the top and 4×4 on the bottom.

 

 

 

Technic gears can be used as circles too. These two gears below only have gear tooth on one side, so they are perfectly circular on the other side.

 

 

 

This shooting disk is interesting because its diameter is between 1 and 2 studs. Very few pieces are of this size.

 

 

 

Sometimes you don’t need a filled circle, but a hollow ring. Here are some of your options.

 

 

 

Most of the pieces above has a hole in the center, which means they can be connected together concentrically. As the Leaning Tower of Pisa in the cover picture, connecting various different circles together could give you surprising results.

UPDATE:

One brick that I missed is this round shield. They are wonderful as circles. They are slightly larger than 2×2 studs. When you attach a 2×2 round tile or 2×2 dish on it, it makes a nice rim. Unfortunately it doesn’t come in too many colors.
