My sister wanted a stair for her dog and she kept bugging me to build one. I kept refusing because excuse me, I’m a very busy man. After continuous bugging and even making my wife interfere, I decided to indulge her and just help out. So I have never built a planet stair before so like you, it was my first time and I hate not doing things well. The stairs came out well and guess what? I had a lot of help from the internet too. How did I make my stairs? To begin with, I got the materials I needed. Please note that the measurements I used are for a dog stairs with three steps. If you want a longer staircase then you have to increase the measurement proportionately.

(3) 1 in (2.5 cm) x 1.5 in (3.8 cm) x 5.5 in (14 cm) vertical tread cleats
(2) 1 in (2.5 cm) x 1.5 in (3.8 cm) x 8 in (20 cm) long horizontal tread cleats
(1) 1 in (2.5 cm) x 1.5 in (3.8 cm) x 5 in (13 cm) short horizontal tread cleat

Make A Mark On Your Wood
To begin, lay one of your side planks down on a flat working surface. Pick a side that you want to be the front bottom of the staircase. Using a measuring tape or a ruler, measure 6 inches or 15 cm and make a mark with your pencil above the corner. Remember, measure twice.
Create A Mark On The Wood In Front Of The Top Rear Corner.
Find the part that is located diagonally across the bottom front corner. This would be the top rear corner of the staircase. With the aid of a tape measure or ruler, create a pencil mark 8 in or 20 cm in front of the corner.
Draw A Line Between The 2 Marks.
Put a straight edge in between the two marks that you have made and trace along the edges so you can create a solid line.
Cut The Marked Line
Place the wood on a sturdy working table. Place the plank in a way that the marked line is not on the table. Secure the plank with wood work clamps. Using your circular saw on one side of the marked line, turn on the device and slowly cut through the wood. When you’re done, repeat the entire process with the other side plank. Don’t forget, safety first. Remember to wear your heavy duty gloves and protective goggles for safety.
Put A Vertical Cleat .75 In (1.9 Cm) From The Front Edge Of The Side Plank.
Put a plywood on a flat working surface. Find the the bottom front corner and measure 0.75 inches or 1.9 cm. Use wood glue to the widest side of horizontal tread cleat and put it so the front edge lines up with the measured distance.
Using The First As A Guide, Fix The Remaining Cleats
After you have fixed, your first cleat, using it as a guide, fit in the 1.5 inches end of a long horizontal tread cleat with the upper rear side of the first tread cleat, then hold it down with wood glue. Next, line up the 1.5 inches bottom of a vertical tread cleat with the top rear side of the horizontal tread cleat and secure it with glue. Repeat the process with another vertical and long horizontal tread cleat, thereby, creating a staircase pattern.
Nail Your Cleats To The Board
Check that each cleat is leveled using a speed square. After this secure the cleat with nails to the plywood. Make use of 1 inch finishing nails. To be very secure, use three to four nails per cleat. Make sure they are evenly spaced. Repeat the entire process with the other side plank.
Attach Your Vertical Risers To The Vertical Cleats.
Put wood glue into the front edge of the lowest vertical cleat, after that, press a vertical riser into it. Ensure that the riser is levelled, then secure it by pressing 1.25 in finishing nails through the front of the riser into the cleat. Do the same for the other vertical risers and cleats. When you are done with the others, attach the opposite ends of the risers to the cleats on the other side plank.
Fix Your Horizontal Risers To The Horizontal Cleats.
Put wood glue into the bottom edge of a horizontal riser and into the top edges of 2 parallel horizontal cleats. Press the riser onto the cleats, make sure the front edge is directly on top of the adjacent vertical riser. Fasten the riser by pushing 1.25 inches finishing nails through the front and top of the riser into the horizontal cleats. Continue this process with the remaining risers.
Nail Your Support Plank To The Back Of The Staircase
After that, put glue on the back edges of your staircase, press your support plank to it. The plank should sit firmly against the side planks and upper horizontal riser. After that, secure the support plank by nailing 1.25 inches finishing nails through the plank into the other parts of the staircase. There, you have your wooden stairs. You can try to customize it by staining, painting it or applying decorative trimmings to the sides. Whatever tickles your fancy.
