Step 4: Construction
Remove the chair and finish drilling the holes through the skis
Turn the skis over and use the 3/8” bit to drill a countersink hole for the head of each bolt.
Run a machine screw through the hole, making sure it doesn’t protrude. If it does, countersink a little deeper. You will seal the holes later with hot glue.
Place the chair onto these screws. This will help align everything square.
Measure the distance between the inner edges of the skis where the legs are attached.
Align the skis parallel (using the measurement you just took) beneath the other chair legs.
Drill a hole through the wooden spreader partially into the skis. Center the holes.
Remove chair and drill the rear holes just like you did the front holes.
Use two more machine screws, washers and nuts to secure the wooden spreader bar.
Attach washers and nuts and tighten down everything with wrench
Place the chair back onto the screws once again, add washers & nuts and hand tighten snug.
Drill 5/32" holes through the chair legs and the wooden footstand/spreader bar.
Insert machine screws with washers through these holes, add other washers, nuts and tighten everything down with the 3/8" wrench.
I used drywall screws to attach another 1x2” for a bigger footstand/spreader bar. If you use a 1x4” you won’t need this piece.
