I have a mitre saw and a table saw on stands, and that looks exactly what I've been looking for.
Did you follow plans from somewhere? Or create all on your own?
We put/have solid hardwood in our kitchen and dining areas. Was put down, then sanded/finished. I know different process than pre-finished, but haven't had any problems.
For any spills/etc we just wipe down/clean after. We don't have anything covering the floor.
Take granular fly bait, a dish that's only about 1 inch deep and some Coke. Put fly bait in dish, add Coke. Go to bed and wake up the next morning and whatever you have roaming around your property will be dead next to dish.
You can add casters to any base cabinet.
The bamboo tops are (usually) screwed to the base cabinet top. But if you wanted to somehow attach the bamboo top to the wall you should be able to with the right bracket/etc.
Have you looked at the GoPro Hero Session? I have one, and if you're wearing it, its so small/light you don't notice it. Good video quality and image stabilization. Takes memory cards, and could probably hook up a USB battery pack to it for longer sessions.
