Hi all, can I pick your brains please?
I'd like to know whether you think the design is strong enough, or whether it will need additional bracing. I'll be welding it all together with a cheapo gasless MIG, as that is all I have access to.
I'm a novice, looking to build the following contraption - It's a large harmonograph. Plans are as follows;
The legs (green) and pendulum (blue) will be 3m lengths of 2mm thick 25mm x 25mm box section.
The Gimbal assembly (Yellow and Red) will be 2mm thick 30mm x 30mm box section.
The bob will be concrete, about 60kg.
The green legs need to be removeable so I can put them on the roof of my car.
This is roughly how it should work -
Any thoughts very much appreciated!
Thank you,
Daniel
