In order to get a heavy and balanced flywheel, most of people will directly choose metal to process.
For me, I was inpired by the gyroman projects, like below:
Notice that in the flywheel, the author put lots of coins in order to weight the wheel. Which was quite smart and low cost.
So I went to Bank, require 5 dollars’ peny
Cut a wood wheel with CNC, making lot of holes to put the coins
Final results looks like this:
Here are some thoughts:
- It is a good way to make a heavy wheel, with a simple and low cost way (yes, directly use money can save your cost)
- It is easier to keep the weight outside the wheel, if needed
- It won’t be a balanced way, because most of the penys are not as the same weight and size, because of corruption and worn out during usage.
