Building a Lego Transformer: Things to Keep in Mind

The actual building process for this particular transformer isn t terribly complicated. However, you ll want to pay close attention to the instructions BrickMecha has provided during the course of the video. If you have trouble with the step-by-step instructions, you can check their website for more details.

Doing a kit-bashed build is a great way to see whatLegobricks are really capable of. This is especially true for folks who like to tinker. It might not have the brand appeal of the licensed kits. However, you can readily apply these steps to your own builds to create something wholly new.

Before getting ready to build this transformer, take the time to sort the pieces you ll need per section out beforehand. This will help you stay organized and on track, as well as help with tracking your progress.

Make sure your pieces are in a clean and well-lit workspace. This will help reduce the strain you might experience during the course of the build. Of course, this isn t a time-consuming custom build. Having a clean workspace also helps so you aren t misplacing parts.

There are ways to make this particular design unique. If the provided colors aren t to your liking, you could always choose your own uniform colors to make a custom transformer.

You would of course still need the same pieces. However, you get something totally unique that is yours alone.

Assembly is straightforward, as all of BrickMecha s content can be. If this particular build isn t to your liking, you can always seek out another build on theirYouTubechannel.
