Making a Push Puppet

A journey through the process

01

Introduction

There’s something timeless about simple mechanical toys, and the push puppet is one of my favourites. The way they collapse with a press of the thumb and spring back upright as if nothing happened has always seemed magical to me.

To understand how they worked, I bought an old, sacrificial one on eBay and carefully took it apart as I could not find any relevant resources online. A couple of things stood out right away. The string threading was clever; it ran across the body and through the plunger in a way that kept the figure stable while still allowing it to flop about.

More Discoveries

Moreover, inside the base, I found a conical spring (dia. 15mm – 25mm, 40mm uncompressed) - an essential piece that gave the puppet its bounce while keeping the plunger centred thanks to a recess.

The parts themselves were relatively straightforward, but the scale was challenging. Many of the components measured only 6–8 mm across, which made handling and replicating them tricky. After my chuck kissed my knuckles for the last time, I decided to invest in some Dome Jaws and get a Record Power SC2 mini chuck which I would highly recommend for working with small parts.

The string threading starts at the tail and goes down each hind leg and through the base, it is then threaded through holes in the sides of the plunger which then cross in the middle of the plunger, before exiting the remaining two holes on the opposite sides. This means the rear left leg is connected to the front right etc. They then travel back up through the base, and up each leg until the two strings meet after going through the body and travel together up the remaining parts of the neck. These are then tied off in a knot together on the uppermost section of the neck, before that piece is glued into a hole at the base of the head.

Drill Guides

The hardest part was figuring out how to drill precise holes in the body and head for the wires to thread through. After a few attempts by hand, I designed an interchangeable 3D printed guide system that acts as a bushing to stabilise a cordless drill. The base takes a dowel that fits in the tool rest hole on the banjo and has a thumbscrew to swap out guide parts.

I could then create any guides I needed, ranging from simply horizontal holes of varying diameters to holes inclined at precise angles of pitch and yaw. More importantly, I could ensure the entry point of the hole was at the same point on the wood’s surface, so V-shaped holes can be made using two guides of +- 15 degrees.

Assembly

The loop from one back leg to the other can hold a piece of string act as the tail captive when it is pulled back into the tail hole. I used a clamp to compress the spring, so it was slightly recessed in order to achieve the correct tension when tying off the neck knot, which was fiddly business. I would advise doing the assembly over some sort of tray, because one false move sends all the pieces flying as the puppet tends to self-destruct.

Finishing Thougths

In the end, the giraffe came together well, and I added a set of tiny antlers to complete the head. At 2mm at their narrowest point, they’re the smallest I’ve turned and it was a satisfying detail to finish off the project.

Introduction to 3D Printing for Woodturning

A beginner-friendly guide to understanding how 3D printing technology can enhance your woodturning practice with custom tools, jigs, and accessories.

01

Why 3D Printing?

Traditional woodturning relies on specialized tools and jigs that
can be expensive or hard to find. 3D printing allows you to create
custom solutions tailored to your specific needs, from simple
tool holders to adaptors and complex measurement gauges.

What is 3D Printing?

3D printing allows the creation of complex objects without wasting material as it is additive, rather than subtractive like typical machining. The most prevalent type is Fusion Deposition Modelling (FDM) which involves semi-molten plastic being squeezed through a nozzle  and deposited like continuous toothpaste by computer controlled motors. 

03

Getting Started

You don't need an expensive printer to begin. Entry-level FDM
printers can produce durable PLA or PETG parts perfect for jigs
and guides. Start with printing available designs online for quick results before learning how to model objects yourself.  You don't need an expensive printer to begin.

Horses for Courses

The orientation of the print will matter as the layers are weak to shear forces and will tend to separate if force is applied in the plane of the layers. This is also why FDM printed parts should not typically be used in safety critical situations, like for use in custom chuck jaws, without proper evaluation of the forces involved.
Centering jigs for mounting stock, diameter gauges for consistent sizing, sanding guides for uniform finishes, and custom chuck accessories. These printed tools provide precision that would otherwise require expensive commercial solutions.

Material Selection

PLA works well for low-stress jigs and measuring tools. PETG offers better durability for frequently handled items. For parts that need to withstand heat or pressure, consider ABS or nylon. Always test your prints before relying on them in critical applications.

From Sketch to Lathe: Designing Bead & Cove Gauges

A journey through the process

01

Sketching the Idea

Before I touch any software, I start with paper. Sketching lets me quickly explore proportions and how the gauge will interact with beads and coves. I mark out my ideas for the key features including the ends for bead and cove fitting, plus the ruler notches for layout. My initial thoughts for its shape and change as I iterate through trying to fit all the features into one compact design.

Creating a Digital Model

Once the concept feels solid, I move into a piece of 3D modelling software, such as Fusion 360. This  gives me the flexibility to iterate quickly and visualize the tool in 3D before printing.

Preparing the Print in a Slicer

With the model complete, I export it to a slicer, such as Bambu Studio. The slicer software takes all the geometry from the 3D model and converts it into a series of line paths that the nozzle of a 3D printer can follow, effectively creating the set of instructions for the 3D printer for it to make the object. As part of this, the layer height can be adjusted for strength and finish, the model can be split to allow for multi-colour printing, and the density of the finished object can be changed.

Printing the Gauges

Finally, the file is sent to my Bambu Lab P1S. Watching the design come to life layer by layer is always satisfying. PLA gives a lightweight but rigid finish, perfect for repeated use at the lathe.

05

Repeat

Through testing the gauges, I can quickly iterate through several tweaks to make them easy to  use and as feature packed as possible. I rinse and repeat this process until, along with the help of some testers, that I am satisfied with the finished product.
