Thanks.
Glad you all like this toy.
I wanted to create my own star engine. Now i have a "know how" in solenoid engines, it had to be this kind of machine.
It's been a pleasure to design and build.
AOG : solenoids are tiny commercial items. Chinese things found on ebay for a few money. It's quite long to arrive but for the price...
I've machined aluminum dummy cylinders to wear them.
Very soft slide of the mobile rod and good spring recall. They all worked. But it's still secure to order more than needed...
