If you want to build stuff in your garage it’s a good idea to build a work bench first. You’ll be like Kris Kringle in there. Making all sorts of gadgets and reaching for the upper echelon of diy life.
But when you build that work bench, put wheels on it.
While you’ve just built the thing and all you want to do is to be done and start building other things on top of it…go make one more trip to the hardware store, buy four locking casters and screw them into the legs.
Wheels make it flexible. Wheels let you adjust. The project in six months with the extra long 2x4 will thank you.
It’s one thing to be willing to adjust when the project calls for it…but the ability to adjust allows for it to actually happen.
Build your thing with sufficient adaptability.
