It’s never going to be a garage but it’s kinda small for a shop. The so-called bench is 7’ long, 25” deep. The DW779 I have here has a big footprint and I don’t see how they would fit together.
You don't show much of your shop to fully gauge the room. For a small shop, you might be better off with a mobile mitre saw bench.
April Wilkerson built one a while back that seem practical... she uses a fair range of tools (all subsidised), however, most cuts should be relatively easy
If your first cut is too short... Take the second cut from the longer end... LBD
Well I have a Dewalt 12" 705 on the Dewalt stand. I put the stand on a mobile "cart" Ply w wheels. This way I can move it around. I added the Fast Cap best fence with their stops. Works well for me.
