I’ve been watching a lot of these lately. Showing how to reproduce fine detail in lenses, and other items, using diy silicone molds.

 
I have to order from Smooth-On quite a bit. Bity Mold Supply have gone out of business, but they still have a lot of similar videos on youtube, as well.

Exercycle made from scrap parts and scrap wood. The fan is very welcome, and there's an adjustable friction device to add resistance. I bought four small bolts and the speedometer. The Schwinn version is over $1k, and weighs three times as much, although it does add arm motion. Legs are plenty to work out the heart and lungs.
