this was created for a specific purpose. I needed a narrow step stool for our bathroom. It also had to be three year old proof.
Step 1: Making the legs
I wanted this to be simple but with a twist. making the legs round seemed to be both. There are 9 that are 1 1/2" diameter by 6 1/2", 14 1/2", & 22 1/2". 3 of each. all of these were done with 2X4 ripped in half. I used scrap stuff but one stud new would make all of them plus the tiered leg. If you don't have 1X4, glue two 2X4's.
Step 2: The tiered leg
this will be the hinge for the smaller steps
I start by gluing a 2 X4 and two 3/4"X4" together
The bottom leg is 6 1/2" tall and 3" diameter
the middle leg is 8" and 2 1/4" diameter
the top leg is 8" tall and1 1/2" diameter
The lathe handles this pretty good but it is a slow and tedious job taking off all of this wood.
Step 3: Cutting up the three steps and the bottom of the stool
I just used some scrap 3/4" plywood. If I had known how cool this was going to turn out I probably would have used cabinet grade. oh well
First piece final measurement is 12"X23"
second step final measurement is 9 1/2"X20 1/2"
Third step final measurement is 7X17 3/4"
And the bottom board is 12X23"
I learned the hard way to get my measurements from the top step down. If you go from bottom up like I did, there may be multiple cuts to make everything fit. When I connected the legs to the tread I used 2" coarse screws and pre drilled with an 1/8" pilot bit
Step 4: Fitting the legs and steps together
Once I put the steps in, I realized there was a need to trim the corners to allow a smooth transition.
Step 5: Cutting out the corners and bottom plate
This step is just to reiterate the trimming for the two moveable steps. I also had to make the bottom puzzle piece easy to fit and slide. It did take a little rounding on each outside corner. I didn't take any pics but once everything fit and moved well, I disassembled and sanded with 220 grit paper
