I got the first batch of my laser cut gears yesterday (still waiting on more). I am so excited! Looks like they are going to work. It is great to have pretty much created my own box of blocks to play with.
7.5" diameter, 4.25" diameter, 2.5" diameter, hole 5/8"
2" diameter, 1" diameter, hole 1/4"
2" diameter, hole 5/16"
These gears were originally designed in Sketch Up and then fine tuned in Illustrator.
Next step = play. Spent a long time at the hardware store picking up nuts, washers and dowels, etc. I also rummaged up a pile of random metal components to explore integrating with the wooden gears.
First things first, make one gear move another. I plan to start by only small little gear objects before getting carried away with some of my larger scale ideas.
