It took me a lot of looking around, searching prices and deciding what to build to flatten these 4 panels. Flattening jigs can be simple or complicated, also expensive or inexpensive. This round table build is my daughter’s request, meaning, I don’t make any money out of it. Therefore the jig had to be a lasting one but inexpensive, this one cost me less than a hundred dollars to build plus a bit for around $49. You keep teaching that I’ll do my best to keep learning. Thank you all.
