Tony has made a good point about the brushes, another idea especially if you're painting with enamel (turps based) just pop the brush in a glass of water if you're going to use it later on or the next day, then give a good shake, and away you go.
With a roller and brush in acrylic and going to have lunch roll the roller around in the paint putting a heavy coating on it, same with the brush, it will be fine while you eat your lunch, just roll it around on tray when you want to start again, getting rid of the heavy load.
Randomx, if rocks, scraps and metal are going to be thrown into your trailer you would be best to get a new metal bottom installed, ply won't last that long with all of this be thrown in it, but it's a good suggestion by Tony.
If you're drilling metal, start with a smaller drill bit then work up to the size you want, but give it a rest for a few moments, otherwise you will burn it out and then it won't even drill butter.
If the door bit turns red, it's useless, throw it away.
Drilling a hole in a door for a new one, also take out the round circular bit, give it a rest, but by doing this it removes all the chips from the cut, otherwise you will be trying to drill through the door plus the chips created from the cut.
Let the drill do the work, pushing it as hard as you can will be worthless, you're putting too much pressure on the drill and the drill bit, and to buy any drill bits from a cheap store won't do anything except waste your money. Geoff.
