Makes me cringe but, a lot of the things I do make other people cringe. If you are familiar with the tool and use the established safety methods, all should be well. So the edge quality is reliant on the miter gauge or is the stock resting against the cutter supposed to be part of the guiding system?
You were building an awfully short bed with 6' boards. Point well taken that if all a guy does are jewelry boxes then it wouldnt make sense to design a shop exactly the same way as a guy that only does moulding. However, who is that specified in their portfolio of work? I certainly am not. I could be making a bunch of 2.5" by 2.5" table number bases for my wedding one minute, or a 12' breakfast bar top the next. I assume most hobbyists operate across a broad spectrum of scale. I do. Using this assumption, I stick to my original thought that there is an ideal layout regardless of personal projects. It will never make sense to have your lumber storage at the opposite end from your primary means of breaking it down into rough project parts. Just as it doesnt make sense to have your shaper, router table, drill press, bandsaw, table saw, work bench, and miter saw in between your jointer and planer. Those are two tools that work in tandem with each other and they should be in close proximity. This stuff isnt rocket science. It can become rocket science when you have fixed constraints, but in the OP's case he kinda has carte blanche.
My customer come and go in bunches it's been slow for me this year but it's worked in my advantage.
Some of my customers are other woodworkers that don't have the time or skill to make what I offer.
Just be patient,original,and confident in or work.It takes years to create a following but maybe you will get lucky and have a nice burst.
So be ready.
Dont be a perfectionist but let excellence be normal for you.
