Hello
I am planning on building a 4" scale compound steam engine. Changing the linear scale by 1/3 affects area by a factor of 1/9 and volume scale by 1/27. Physics doesn't scale so I am concerned that changing the linear scale may require modifications to the steam path dimensions...
Hi
This guy has created the best DIY electronic lead screw I have seen on the Internet.
It should be adaptable to similar applications like electronic tool grinder, rotary table, gear cutter, etc.
