THE WORKSHOP – DIY Mini Bertie Custom (PART 1 of 5) by markovengine

It’s been a bit since we’ve updated The Workshop with any new content so I’m incredibly happy to be able to offer the first part of a massive 5 part tutorial series by the extraordinary toy artist/mod, markovengine! Those who hang around the official threeA boards are sure to recognize his fantastic work. His skill at crafting fully realized miniature versions of well known full size bertie colorways is astounding. (You can check some of his stuff here! ) Through this series, you’ll get the step by step and learn from him exactly how to make super detailed mini berties of your very own. (check out our review of mine berties here!)

A massive thanks to markovengine! Rad Toy Review is thrilled to be able to offer this series to you and we truly hope you get something rewarding out of it!

Part 1 : Preparation before painting


I don’t  believe I did anything very special.

The steps I use are essentially the same as when someone builds and paints a plastic model.

First, measure the width, shoulder to shoulder on your mini bertie. It should be about 2.12mm. Remember that number.

Separate the arms from body using the nippers or a saw.



Cut them clean and make the cut as close the arm/shoulder as possible.



Here I filled the chest area with some putty.

It helps to have a smooth surface when applying decals.

This step isn’t required, but makes things easier down the road.



At the center of the shaft of the shoulder joint (on both arms and body) drill a small hole.

To keep from making a mistake I gradually increase the drill bit size a step at a time to enlarge the hole.


The holes should line up and reach around 2.5mm at the body and shoulders.


Now you need some sort of rod to run through the holes in the body and attach the arms to. I use cuts of plastic model frames which measure out to 2.5mm.



While I used a model frame, it might not be a bad idea to measure what you have available to use as a rod before you start drilling the holes to size on your bertie, just in case you need slightly different sized holes to fit whatever rod have laying around.
Here’s the rod cut from the frame.


Left : When we measured the shoulder width it came out to 2.12mm.
Right : Cut a measure the rod so that it will fit the shoulder pieces. Adjust it a little at a time until you have the width at 2.12 mm.

Using a metal rasp and some fine grit sandpaper, shave off the chest putty and smooth out the plastic seams. (shown by a red line)


Insert the shaft into the body.

Check the position to ensure it’s properly centered and then bond the shaft to the body using super glue.

I’ve used more model frame scraps to create handles for each parts. This will be a huge help when painting.
For now, we’re finished with part 1!


Continues in Part 2 : “Paint body and create decals”!

    • Not in this one.. I’ve seen others tackle that. I’ll see if I can track someone down to write a quick “how to” and I’ll just append it to this post. thanks for reading!
