Smashedfinger, those are beautiful benches! I'll bet they were serious and not easy projects. There are easier ways to build a nice bench these days. The bench hardware business took off about ten years ago and there is lots of really good, innovative hardware on the market today. Most of it is pricy, but installation is sure a lot easier than building this traditional tail vises like yours. Take a look at:

IF you're interested in a maple top but don't want to go through the glue-up hassle, take a look at Bally Block Maple bench tops. (
https://www.butcherblock.com/product/ind...bench-top/) I ordered an unfinished 24" X 72" X 3" maple top from them, glued on 4" thick dog hole strips and mounted my vises. It is a heavy, bomb-proof bench top. I did some calculations and discovered that it was only a little more expensive than if I'd purchased the raw materials and laminated the top myself. That was well over ten years ago, so things may have changed. In any event, it was a lot easier than building a bench top and vises from scratch.
I can't answer whether you NEED a solid, real workbench or not. I just know that mine is the best, most useful thing I've ever built and I wouldn't be without it. It sure makes woodworking a lot more pleasant that struggling with an inadequate, make-do bench.
My $.02. Glad you're back woodworking and I hope you enjoy it.
