How can I build an 8x8 plywood wall with 15 degree slant?

[Pablo]

I would like to build a plywood wall to use as a tennis backboard. It is recommended that the wall be tilted slightly back at a 15 degree angle. I know how to work with wood a little because I used to build custom kitchen cabinets but I'm not completely sure on how take on this project. I plan to make the wall with 8'x8' dimensions. I have two sheets of 3/4" plywood (4x8) and about 20 2x4's. I can get more if needed. Any help would be greatly appreciated.

Thanks in advance, Pablo Mata

You want to build a frame and then mount the plywood on the face of it. From the side you want to make a triangle shaped support made from three pieces. This can be done on the ground and then stood up in place.

Cut the bottom of a 2 x 4 at a 15 degree angle. Cut the opposite end to the same angle so it will be perpendicular to the ground. Nail this to a 2 x

1. Cut another to complete the triangle. This is going to get nailed to the flat plate that will be the bottom for the wall. After making the frame, attack the plywood.

Screw both plywood sheets to four 2x4's spaced appropriately. Use two hinges to screw top sheet of plywood to two other 2x4's with their bases cut at a

15" angle - those will be the legs.

Simple. Build it as a standard frame wall, 16" centers. Bevel the base rail 15 degrees on the TS and mitre the bottom ends of the studs at 15 degrees. As for support and making it stand, depends on the situation. If you are in earth, you might want to set 4X4 posts in with cement and attch to the studs. On cement, you might want to use some simple tapcons to secure the base as well as the posts.

Build it plumb and place it on a 15 degree slope.

Cut 15 degree angle on 5 2x4"s for 24" stud spacing or 7 2x4's for 16" spacing. Nail to 8'-0" long top and bottom plates.Nail plywood to frame. If the wall is to lean against another wall, then you are done. If the wall is to be free standing, then you need to add angled braces at each end to keep it from falling over.

go find a construction sit where the wall framing is exposed. bring a pad of paper and something to write/draw with. if you can find a jobsite where the walls are being made while you watch so much the better.

note the relationship of the top and bottom "plate" (2x4) to the studs (verticals). note the presence (or absence) of mid span blocking. measure the distance between the 2x4s. look if you can at the nails that are used to hold it all together.

The information given on construction is good. I will add that for an 8' high piece of plywood to lean back 15°, the length of the base is 24 7/8" and the height is 92 3/4".

With a slope of 15 degrees, the vertical height of an 8' sheet is

8cos(16) = about 7'9".

Built a frame across the room which drops enough from the ceiling to leave 7'9" from the floor. so if the ceiling is 8/ the frame is only

3" deep.

Nail, screw... the plywood to a baseboard at the wall and to the frame base. This will move the ball to the floor in front of the serve on return.

Thank you all for your replies. I hope to start on it this weekend.

Thanks again, Pablo [e-mail]
