New Delivery for 14-PCS Hex Key Sets packaged by spring ring for Mauritania Manufacturer

Our G series silverware benders have been discontinued. Please refer to our newest model, the Flatwearable Silverware Bending Press, which outperforms any silverware bending tools on the market today. www.flatwearable.com

I have been wanting to make one of these for a while as I have seen plenty on YouTube. It took me a while to find somewhere that stocked these old style mousetraps. All the stores seem to stock modern humane types that are no use for this project. Eventually I found some in an old style hardware store. This was an interesting build as I learned something practical about leverage and gearing.

If you have a question it is probably worth reading this video description first because the answer may already be here. To help you find my videos I made two search guides https://youtu.be/ceBSOoOHcgw or https://youtu.be/Zj4UgwkwYRk or checkout my playlists page https://www.youtube.com/user/GrandadIsAnOldMan/playlists?flow=grid&view=1

Adjust the thickness of the back axle to change the “gearing”. A thicker axle gives more leverage to the wheel so a long arm will work, but will reduce the distance travelled as it takes more line with each rotation.

I thickened mine up with a foam rubber disc but I am sure I could have got better results with something a little thinner, just slightly thicker than the bare wooden axle I started with.

I suggest you try building the rear axle diameter slowly with layers of cardboard or tape to find the optimal combination for your mousetrap.

I wrote this reply for somebody who wanted more information so I am pasting it here for others to see.
At around 8.20 I show that I put a cable tie on the back axle. I tie a loop in the end of my string and that hooks over the cable tie on the axle to hold it in place as you wind it up. When the string unwinds the loop can drop off the hook and the car can carry on freewheeling. The other end of the string is tied to the big red lever I attached to the mouse trap arm. The red lever arm is used to extend the lever of the mousetrap so that it moves further and you can use a longer length of string and the car goes further. I used fishing line instead of string because I didn’t have any string.

I have thousands of videos on YouTube covering a wide range of subjects. To find them follow my search guides https://youtu.be/ceBSOoOHcgw or https://youtu.be/Zj4UgwkwYRk or see my playlists page https://www.youtube.com/user/GrandadIsAnOldMan/playlists?flow=grid&view=1
Generally my projects are for my grandchildren to enjoy. OK, I enjoy them too. If anybody else likes them, that is a bonus. I like to keep my work as simple and basic as possible so that it can be copied easily and improved by anybody who wants to try themselves. I recycle or repurpose items rather than buy new and when I do buy I like to keep it cheap.
