that board is a work of art!! wow! i built a aluminum luge but owning a small car sucks for transport.i would like to know if there are plans for sale ?
front truck under thighs, back truck under/slightly behind head... trace & build to your body shape/size, and it'll be better than anything by plans... or at least better fitted to you.
48x12, angle back to 5.5" wide at the midway 24" mark. front truck 10.5 inches from the front, back truck 3/4" from the back. those were the dimensions i had found and they work well. Mine is a bit narrower in back because,well, i suck with a jigsaw and had to redo it a bit.
I have only gotten to ride it once. It was fun i do need some harder bushings though. Other wise it handles good, i just cant compare it to a luge since i havent ridden one. Super easy to make, i must say.
