Well, in my case I just offer to drop on by in my workshop.
There is always something to do.
I have several volunteers working with me after hours.
The only thing I ask for is to show some interest in the work and to be a bit handy
I run a one man business here and all others you see in the images posted in the FTS thread are friends and volunteers.
If you are interested yourself, you do not even have to come to my workshop, since you are certainly too far away. Just tell me what you want to make and you can do it at your place.
The point is: just ask those folks and most of them certainly will have something to do for you.
Cheers!
