Noel C How in the world did you form the tops of these skis? I would think they were formed in a very very very expensive die in a multi-ton press. And how long did it take you to build them?

Lynn all this talk of photography is like getting a kick in the duff. So aI went out ant ook a few "snaps" of my skis The very first one has a perspective that makes the axel look tilted C its not. Thge reverse inserts may give you a few ideas.
Picture 1. These skis are no doubt foam cored as they are quite stiff and weigh a lot less than the wheel and tire they replace.

Picture 2. This is the picture I mentioned with the perspective shift on the axel.
[img]cid:image004.jpg(at)01C965DB.8894B4E0[/img]
Picture 3. This angle shows the axel is straight and it also shows the two thin Teflon plastic runners on the bottom of the ski. Notice no whear bars as the skis are not to be used on bare pavement.

Picture 4.Ski right side up reversing insert upside down.
[img]cid:image008.jpg(at)01C965DB.8894B4E0[/img]
Picture 5.Reversing insert in place on ski. Insert is held in p[lace by a cmall bungee that goes through the I screw and around the axel. ( retainer is not in palce.)

Picture 6.
Rear view of the ski with the reversing insert in place

Picture 7. This angle shows why the reversing inserts should be removed before forward taxiing let alone flight.

Picture 8. Insert in place taken bottom up from the rear.

All these pictures were almost 2M in size I crop0ped and reduced them for E-mail
What I tried to hide is except for a small drift there really isn’t that much snow around here... Certainly not enough to think about landing in bogs on skis. No sign of ice this month.. I have an ocean of water outside my door.
Re the length of the skis Longer will get you on top of the snow faster C as there is less frontal area to plough per sq inch of loading area... but they will also help keep you straight... this is great until you want to turn. Wider skis will give more lift on the snow but with the wide frontal area will be harder to get to lift you to the top of the snow. Wider skis won’t hold your plane as straight as longer skis.. It’s all a matter of compromise.
When I was in high school I used to ski on a set of head 215 downhill racing skis. Speed and stability were no problem...
Turning was! Today the average ski is a lot shorter ability to do fast turns is increased but some of the stability especially in powder snow is gone.
Sorry if the whole e-mail is a bit on the large size for dialup I think it’s less than ½ MB.
Three guesses how I like to fly ( the first two don’t count)
Merry Christmas

Sorry, I didn’t build them but I expect they were vacuum bagged around a couple of foam cores. They are way too light to be layed up with wet cloth and way too stiff to be HDPE. Each ski only weighs about ten lb. if that... My cat may be heavier. The thing I was trying to show Lynn was the reverse tips the last owner made to tow the plane up to a bog he used as an airfield and the slight tip up along the full sides of the skis. The side tip up makes it a lot harder for the ski to trip while taxiing.
