I've built everything on my S10 Blazer myself. Only have a sawzall, an angle grinder, a big 1/2 drill, and a little 110 Lincoln mig welder. So building stuff is easy, just have to set your mind to it. my project is going on 4 years now.
I built mine over the course of a year... When it went under the knife it was a typical, 4" off the shelf lift, d44 w/ truetrac, 12b w/ lockright, 36" TSLs and a minimal cage...
I pulled it into my brother's garage and started cutting... Used a HF bender, borrowed welder, grinder, saw-z-all, notcher in a borrowed garage...
I had a pretty good game plan going in after watching everyone's rigs on the trail... Saw what worked and what didn't... I wanted to build as much of it as I could... Fabbing is not for everyone, but I like to build stuff...
It can get overwhelming, you have to make a list of tasks and follow each one through... When you start on the next task, break it down on another list into steps and follow that through... Before you know it, you'll turn to look at your rig and it's almost ready for a shake down run... That also helps with staying excited about working on it... It feels really good to check something off and get started on the next thing...
I've been putting together a list for the bus build now... I was starting to aimlessly wander, working on this for a bit them jumping to something else... I realized that I have to get on task and see each thing through before jumping into the next task...
It gets real easy to jump from one thing to another and leave the crappy work that sucks to do until later... Before you know it everything just has the sucky parts left to build and you get discouraged...
