Flip the classroom

I like the idea of the flipped classroom because it would give my students more time to work on projects in the shop. It seems that by the time we get started on something we have to stop and clean it up. However I do see some drawbacks. What do you do with students who do not have a computer or internet access at home? Where do these flipping teachers find the time to make these lessons? I seem to stay busy from sun up to sun down everyday and do not have time to record a lesson after hours. The flipped classroom sounds to me like having two jobs. As teachers we barely get paid for the 8 hours we are at school. I cannot imagine what my hourly rate would be if I had to go home and teach another 8 hours. Flipping could be useful for special lessons but I don't see how it is feasible for lots of lessons.
