Video demonstrating our first experience of The Relaxitrator's inexplicable attraction towards lamp posts. (Note: Has some speed-induced swearing)
We only have photos of the complete sled but the assembly process is simple enough to explain.
A pair of old skis
An office chair
Some rough-grit sandpaper
A Hand saw or chop saw for cutting 2x4's
A Hot glue gun
A Drill bit about 1/4 the diameter of your screws for predrilling
~30-40 Screws (we used some drywall screws we found lying around but this is definitely not optimal)
Step 1: Prepare the Runners
Cut some 2x4s to the length of the chair seat.
Drill the 2x4s into the skis where the bindings were. (We used 2 layers of 2x4s because we were concerned about snow clearance)
Make sure to drill the wood to the skis very securely - this is an important joint. To prevent spliting, be careful to leave enough space between the screws (about 1 1/2 inch) and always predrill your holes with a thin drill bit.
