DIY Snow Skis - Yet Another Thread
And then, just when I was starting to have fun, total buzz-kill...
I won't mention the brand name but I expect you've come across these at your local hobby shop. Did I mention they were cheap? As with most things, you get what you pay for. So I tossed em in the bin, fired up the CAD software & set about designing my own skis...

I've heard Formica (used in counter tops etc) makes a pretty good ski material. Tough as nails & best of all, nice & slippy on one side...
I used a heat-gun to help form the ski-tip...
The ski's spine I made from scrap pine. I used contact cement to temporarily tack my templates to the wood...
A little time at the scroll-saw, some sanding & we have a pair of ski-boots...
Clamping while the epoxy cures...
That looks like it might work...
Happy with Mommy & Daddy ski I produced a Baby ski too...
Masking off the slippy side of the Formica in preparation for some paint...
A dusting of primer...
A coat or two of black & they're looking the part...
While this looked good on the bench, as expected when I picked her up the skis flopped around all over the place. My el-cheapo skis used a spring to hold the skis in a slight tips-up attitude. While I could have copied that system I chose to take a slightly different route...
A length of wire bridged between the forward section of the two skis attaches to a spring. This holds the tips up while in the air & also helps keep them parallel to each other...
String attached to the rear acts as a stop & maintains the tips-up attitude. Once she touches down the string goes slack allowing the skis to follow the terrain...
I slipped the string under a screw & washer so that I can easily adjust the angle of the skis...
The baby ski is a little simpler, looks like it'll work fine with just a spring...
Well there she is, ready for some fun in the snow...
No doubt there's lots of other DIY ski designs out there & this obviously is not the only way to go but I figured I'd share what I came up with.

Let it snow, let it snow, let it snow!
Oh yeah & before you ask, the plane is a Spacewalker by House of Balsa. Awesome park flyer & a lot of fun to build.
