Is there anyone out there who has a solution, course, instruction YT video whatever that helped them keep their bench empty ?
Many years' experience both at work and at home has taught me to prioritise bench space over virtually anything else. This sadly requires continuous effort to maintain and so it isn't a perfect solution by any means.
I have a much smaller work area than many on here but still have two large benches and one desk in one room and another bench in a small box room. I try and keep the benches as clear as possible although clutter does inevitably build up over the course of a week or so. I just have to find time to housekeep it all to keep it clear enough to be functional and not become a cluttered mess. It does still get (very) messy but I do tidy up at least once a week.
I try and only allow the necessary test gear on my bench and keep the rest in storage when not needed. I retrieve and use it when needed (and then put it back in storage).
I don't allow any tool or component storage on my main workbench and try and always keep some shelf space clear and as much of the bench as clear as possible. This does take a lot of effort but it is worth it.
The popular alternative (as seen many times on here and other forums) is to cram all test gear and tools and storage on the bench leaving virtually no space to do anything. It does mean it is difficult to make a mess because there is no space left left to make any mess! It also looks really impressive to any onlooker but I couldn't work like that as I need lots of bench space for the stuff I do.
At work virtually every (RF or hardware) engineer operates in the same way as me. Only populate the bench with the relevant test gear and return any surplus to the storage area. Don't cram tools and component storage containers on the work bench.
