First of all, thanks to Dale Cox. I copied and modified his diagrams on https://www.do-it-yourself-help.com/.
1st diagram shows partial section of wall between my kitchen and dining room. There is a serving window where yellow section is.
My goal is to create pass through opening where serving window is. Opening will be of same width as serving window. I don't want to install door, I just want to create pass through. 2nd diagram shows my goal.
I have already removed bottom cripples (red color) and Sill plate (green color).
Next thing I need to do is raise the height of header. To do that, I will have to cut top cripples halfway (depends on measurements) and replace existing jack studs with longer jack studs to support header.
Distance between left side king stud and right side king stud is around 3 feet 6 inches. I am in 2nd storey condominium, I asked few contractors about whether it is load bearing wall or not. They said that it is partially load bearing, I should be good as long as I only create door opening of same width as serving window and not remove any king studs.
Here are my questions. It may sound stupid questions but I am new to this and need some expert advice.
- What is the first thing I should be cutting/removing to release header ? Cripple studs or existing jack studs ?
- What tool should i use to make sure all 4 cripple studs are cut in level and straight so that it can be flush against top of header when i install it.
After I cut cripple studs and remove existing jack studs, What should I do first ? Nail header to cripple studs first and then install longer jack studs below header ? (If I do this, How can I measure length required for new jack studs so that it is not too long that it can't fit and not too short that it cannot support weight of header.) OR First put new jack studs in place, then rest header on top and then nail headers with cripple studs.
When should i cut my soleplate ? Should it be flush with new jack studs ? I guess yes.
I know that actual width of 2x4 is 3 1/2" but my existing jack studs width is 3 3/8" (1/8" shorter). Where can I get that size ? Building is around 25 years old.
