What you'll need:
4x8 foot plywood. (Free) 3/4 thick
5 inch holesaw blade 1 1/8 hole saw ($60)
Drill. (Housemates/free)
4 foot meta piper ($15)
Wood screws
Old skis (free)
6 pack beer ($12)
sandpaper (free)
I started off by using the 5 inch hole saw to cut grooves into the plywood for the pucks. I ended up cutting 47 to give me 35 inches (88cm) of a rail which I thought would be plenty long enough. Don't cut all the way through and just enough to make the groove as we will be cutting through it later.
What I did next is now use the 1 1/8 hole saw blade to cut the middle hole for the axle metal pipe. We make the grooves because if you've ever used a hole saw blade it will kick if there is no pilot hole.
After cutting the middle holes holes we go back to the 5 inch blade to complete cutting out the big holes.
Thats is as far as I've gotten last night and will update it once I do more!
Hopefully someone uses this!
