1. "whats a DA sander?" Dude, you're on the internet. You can google that, it's a really simple question. I didn't know what one was either until 5 minutes ago when I googled "DA sander" and took a look at the images tab. They appear to be a circular handheld electric sander.
2. "4 1/2 inch right angle?" Once again, google. I wasn't entirely sure what a 4.5" right angle was either, I was thinking something along the lines of a sander used to sand right angles and that the circular part was 4.5 inches. I was half right. Another quick google image search showed me that it appears to be a sander that has a special handle that allows you to hold it at a right angle.
3. "can you explain block sanding? and why thats required?" Google can answer that too! Block sanding sounded familiar to me, so I looked it up to make sure it was what I thought it was. I was right. The first google result was this:
"Wrapping a piece of sand paper around a small block (usually wood) to give a flat surface for sanding larger flat areas"
Essentially, it's pretty much normal sanding. And from the very limited knowledge I have about my dad's power tools, I know they do a rough job. You have to go in and sand things by hand after sanding with an electric sander because the electric sander can't do a perfect job by itself.
I got these answers from less than 5 minutes of Google plus random memories of playing in my dad's and grandpa's workshops when I was in grade school. I barely understand power tools, and this was all very easy information to find. You can find it too.
I'm honestly not sure if you actually want to know the answers or are just asking us a ton of questions without listening for the answers like a bored little kid.
