Hello friends！
Ive made an easy and reasonable 2-in-1 Circular saw slide guide.
It works in two ways: Circular saw slide jig" and «Panel Saw:»

Since this circular saw is fixed with a linear shaft, its very rigid and safe.
It works as a panel saw once you place it on the wall, saving your precious workshop space!
Ive used cheap stainless pipes in this video, but this can be easily upgraded by using linear shafts, turning this into a high-precision and performance jig.
