I printed flat stock for YEARS on a single piece of 1/2" MDO (Medium Density Overlaid plywood) on sawhorses and a couple of hinge clamps for my wooden frames. AND......I paid the bills.
I say Go Get 'em, Tiger!
All the stuff I've made over the years seemed to work to one degree or the other, and it scratched an "itch" that I've always had to make stuff. I once repaired an Allis Chalmers Combine engine block 40 years ago with JB weld that every farm machinery and implement dealer I asked said couldn't be done. They were all wrong....
Right now, I'm modding my old infrared conveyer dryer with only 72 inches of heat, to be a little more waterbased friendly. It is a little Rube Goldberg-esque, but my oh my!... I'm down to 90 seconds of dwell and a HUGE amount of airflow. 4800 watts more heat was required to offset the air increase. 60 seconds even works sometimes.
Just do what you have to do, grasshoppah. Some youngsters can't even put on a spare tire! Work HARD at it and grow your biz. Read lots, and welcome aboard!
