Re: finding true dimensional joists or ripping down lumber
Find a local sawmill. They can custom cut lumber for you. Be sure to let them know what you're doing, so they can select the proper logs and orient the cuts to produce material suitable for your application.
The "Senior Member" designation under my name doesn't mean I know a lot, it just means I talk a lot.I've been a DIYer since I was 12 (thanks, Dad!). I have read several books on various home improvement topics. I do not have any current code books I can refer to. I was an apprentice plumber for two years.
