Hi There,

My name is Jeroen and I live in Holland. I am a low profile hobbyist mainly building models or just things from wood. Mostly I use just a picture to build the model by creating my own drawings.

This year after a family break in France I have seen a huge Trebuchet http://en.wikipedia.org/wiki/Trebuchet I was impressed by it's power and simplicity. After discussing with my kids to build one (small scale) together I started to search the web. I ended on wikipedia where you can find a picture of an impressive model of a trebuchet and decided to build one with my kids.

I found out that this model is also available to purchase on line (179$). However my challenge has always been to build something on my own. I used the picture above to create the building instructions and set the dimensions of the model since the building plans and instructions of this model can not be found on the internet.

To build this model I used only wooden strips 12mmx12mm and round wood of 6mm, thin rope and glue. The material costs for this model will en up around 25$. Next to this I decided to build this one without nails or screws. So everything interlocks and was attached by wooden pins (and some glue).

Tools: Sander, multi tool, vertical dril, battery screwdriver and some general small tools.

I will try to provide everyone with all the tools to create one on your own. Any tips, comments or requests are welcome since this is the first time I use a Blog, thanks and have fun.

Step 1: Trebuchet Base plate

The Trebuchet Base plate:

Well the thing is,... I decided to create a blog on this Trebuchet when I was already done with the base plate. I will try to explain as much as possible. I created a basic plan for this specific item.

Since all corners are exactly 90 degrees this item is rather easy to make. No nails were used and all pieces are connected by interlocking connections fixed with a wooden pin.

Since this piece is was already created the moment I started the blog I am not able to show you exactly how I have done this in this specific item. However I am able to show based on other pieces I have created for this model showing the same technique but on an other part.

How to create a interlock connection: So keep in mind that the pieces used are different then the base plate, however the technique is the same. In case you would like to receive detailed photo's or if you have a question, just let me know.

Always cut both pieces you want to connect exactly halfway. Once done both pieces, it will be a perfect fit.

I use a screw bench to hold the wood in the correct depth. This way I can perfectly chisel away the wood without taking off to much.

Once the pieces have been cut you are ready to create the connection. First make some wooden pins. I use roundwood of 6 mm in diameter. To drill the hole I use a wood-drill of 5.5 mm. To avoid any cracks in the wood just make a subtile point at the end by using a sander. Then fix the pieces and drill a whole to both pieces. When the hole is drilled apply some glue, put in the wooden pin and use a hammer to gently force the pin in.

The connection has then been made and should look something like above. Then you use a fine saw to cut off the pins and use the sander to smoothen the surface. If done correctly the baseplate should be similar as the following detailed pictures.

THe base plate is then finished. Since I would like to create this model as authentic as possible I have used a mini power tool to batter the wood so it looks like real trees has been used (downscaled) to create the wooden pieces. Maybe a little bit overdone, however I think it will look great once finished.

Eventually this model will be painted with a dark transparent paint.

Again if you need more details, just let me know. Next step are the wheel supports.
