1) Read the plans several times before you make a cut!
2) Follow the plans step by step during the build!
3) Slow down - don't hurry. Enjoy the process!
4) I like cabinet screws better then drywall screws. The shafts are thinner allowing more room for play, being off center.
5) I prefer 18 gauge 1/4" crown staples to brads. They pull the wood joints together much tighter then brads.
6) Use atleast one coat of latex paint to prime the boxes before using the final coating!
7) I install the driver in Titans before I put the last side on. I cover it with a trash bag and painters tape. It is so much easier to get the driver in. I remove the bag and tape just before the access cover goes on.

9) The most dangerous tool in my shop is this.

I got my 1st three fingers in a gob of hot glue while installing foam topper in OT 12's. Ya can't get away from it once it grabs . It was no fun peeling it off blistered fingers!
Thanks for reading.
