I decided to make an inversion trainer as a gift. This apparatus helps people learn to do upside down yoga type maneuvers. It’ll eventually get a cushion on top.

Tools Required

  • Table saw/ Circular saw
    • Most saws will work to cut the rough shapes
  • Jigsaw
    • This will help you cut out the curves and complex shapes
  • sander/sandpaper
    • Fortunately, I had some power sanders to help, but this could all be achieved with sandpaper and elbow grease
  • Drill
  • Router
    • This is optional as the edges can be rounded over with sandpaper

Supplies

  • 1/2" baltic birch plywood
  • wood glue
  • screws
  • cushion materials

Prepare a Template

Inversion Trainer - Template Shaping

I started by creating a template piece for the legs of the apparatus. I will be cutting 10 leg pieces out of 1/2” plywood and laminating them together, 5 per side, to make each leg

Cut Out the Legs

Inversion Trainer - Cutting out leg pieces
Inversion Trainer - Sanding leg pieces
Inversion Trainer - Cutting braces
  1. Use the template to trace out the leg shapes
  2. Use the jigsaw to cut out the leg shapes. Try to be close to the line to minimize sanding and such
  3. Here I am doing some preliminary sanding to get the pieces to line up decently for the glue up
  4. The actual design doesn’t have long braces from front to back and I was a little nervous about it flexing and breaking so here I am using the table saw to cut those braces.

Think It Through....

Inversion Trainer - Thinking

Here is me trying to determine what to do next. This one wasn’t really necessary to keep but it liked seeing the gears turning in my head haha

Glue It Up

Inversion Trainer - Leg Glue Up

This is the glue up. You can see the cross brace is integrated into the leg.

Sand It Down

Pretty self explanatory. make it smooooooooth

Round Over the Edges

I used a palm sander and homemade router table to round over all the edges and make it nice and smooth. I really dig how Baltic birch looks all glued and smoothed.

Inversion Trainer - Assembly

  2. Added the short braces to connect it all together

Test!

It will eventually get a cushion on top to make it a bit more comfortable to use.

If you think this is neat, give me a like in the plywood competition! thanks!!
