I would suggest picking a project and just starting. Then as you try and make whatever item you're trying to build that will immediately tell you what tools you need and what you can do without. Honestly if you use common sense looking at the tool when you purchase it almost all of them are good...
I agree, DeWalt is not diy. I'm personally in the Milwaukee battery platform, but have several DeWalt corded items. It's either DeWalt or Milwaukee 80% and then all the other brands filling the last 20%. And 20% would be generous.
Do like the old timers. A 2x8 board with rope tied on each side of board. Then the middle of slack in rope through tractor hitch. Pull tractor forward have assistant hold board down and scrap off material. You will be done before you know it.
I also have the evolution in an earlier version. I think I paid $219 for it. Got tired of renting them for a hundred bucks a day. I've used it all over the place it always works and always starts. It's fantastic haven't even replaced the blade yet and we have cut lots of concrete with it. You...
You can debate the hand tools back and forth all you want. Sure looks like harbor freight has that market wrapped up. And Stanley kind of missed the ball on the Craftsman thing. However the craftsman name still has name recognition. It sure looks like Lowe's is selling plenty of the craftsman...
I put the Cabot on my deck and it faces the west and they usually take couple days to a week to get completely dry usually not sticky in two to three days in the Sun. I'm not sure how long you're expecting. But getting them in full sun would really speed up the process.
Either Sikkens/PPG cetol or Cabot Semi-transparent in different color. I have used both have also used Pennofin, Olympic, Ready seal, Flood UV. They are all similar. All require regular recoats.
I have two of the IR air hammers in the model you're asking about. The trigger is nice. Plus you can get the attachment to add a needle scaler to it. Which is really nice.
Also while you got the decking off is the time to add any extra brackets for securing loads like backup plates. And also the time to redo any wiring if it needs it since you can get everything nice and easy. Also if you have your wheels off check your brakes and all that.
225 75/15 load rating E trailer service tires are what I use on all of my trailers. So you can definitely get a much better tire and they don't cost much more than just a regular one. Oftentimes they cost less than a regular tire.
I would imagine your bearings are going to be a standard size...
On models that are relatively new see within the last 15 years it's just a collar that you push down and that thing releases. Not sure about a super old one may require a tool
Plan on restaining horizontal surface every 2-3 years and 3-5 on vertical. Then it's just the way it is. With the sun UV and weather that's pretty much the limit of how long a stain will last and look good. There's have been many discussions on which thing to use. They all have pros and cons...
