Cut List

Tools Needed: Table Saw, Circular Saw, &/or Miter Saw

For your convenience, I’ve placed the 4 pieces needed to make the Mardi Gras Ladder Chair on a sheet of 4’x4’ plywood.


Prepare Sides of Chair

First, you need to prepare the sides of the chair.

  1. Cut the half moon on the top front with a jig saw or hand saw per the measurements below. The 3 lines at 5 5/8” will help give you a guide to draw the half circle.
  2. Drill ½” hole for 3/8” dowel. 6 ¾” from the bottom and 1” over to left.

Side Rabbet Joint

First, side rabbet joints are optional.

Also, skip this step and join the pieces together with glue and screws.

Next, route a groove on the inside bottom & inside back of each arm using a ¼” straight bit

Roundover Edges

Mardi Gras Ladder Chair - Test Fit

Please note, before proceeding to the next step please test fit the pieces to make sure the rabbets fit.

The purpose of this step is to get nice smooth edges on the entire piece.

Additionally, I encourage you to do this on every piece except for the rabbet edges.

Also, you can accomplish this with a router with a ¼” roundover bit or an orbital sander.

If you plan to use the orbital sander, make sure to make 2 passes – 1 with 180 grit sandpaper and another pass with 220 grit sandpaper.

Prime and Paint

First, make sure each piece is free of dust and debris. A tack cloth is great to use to get rid of dust and debris.

Next, prime each workpiece with Zinnser. This product is very low odor and it is the best primer on the market.

Lastly, I recommend 2 coats of semi-gloss or satin paint of your choice.

First, put the piece together to mark the pilot holes. Mark the pilot holes about 4 inches apart.

Next, Drill the pilot holes while the pieces are next to one another and line up.

Then, put a generous amount of glue on the bottom back piece and join the back to the seat piece with screws.

As a quick tip, use a speed square or combination square to make sure the back piece is 90 degrees to the seat.

Additionally, wipe off any excess glue on the bottom that may have squeezed out to prevent the piece from drying to your work surface.

Cover the rabbit joints with glue and repeat the steps above to the sides, but be careful to not tighten the screws too much. The wood is a bit thinner here because of the rabbet joints.

The screws are simply there to hold the piece together firmly until glue dries. Wipe off any excess glue.

Finally, let everything dry overnight.

Seal Dowel and Mount the Chair

Normally, I don’t paint dowels for Mardi Gras Chairs because they tend to get abused.

Plus, it’s not easy to paint a round object without a paint sprayer.

However, I do recommend sealing the dowel to ensure it survives the outdoor elements and lasts more than one or two Mardi Gras seasons.

Ultimately, the Polycrylic finish works best because it dries quickly and protects the surface.  Remember, apply 2 coats of finish.

As you know, each ladder is different.  Consequently, I didn’t include specific hardware and instructions on how to mount the chair.

In turn, I recommend placing the chair on top of the ladder and make sure it is centered.

Then, mark the holes with a pencil and drill out the appropriate size to match the size bolt you will use. To secure the chair, use stainless steel flat head bolts, 2 washers, and a wing nut for each hole.

Keep in mind, Mardi Gras Chairs are very dangerous if they aren’t built properly and securely fastened to the top of a ladder.

Finally, I cannot guarantee the safety of this chair, so build and secure it to the top of your ladder at your own risk.
