I need a couple of the big washers that go between the ski pedestal and the axle nut.  Anybody have a good source of washers this size?  Menards?  Farm & Fleet?  Etc.?

The local hardware store should have those in stock, they call them "Fender washers."  Send me the size via e-mail and I will go see if they have what you need and mail them to you.

Hi there,
I found some at the local NAPA and they were 2 1/4" OD and had to be machined out the the proper 1 1/2" ID plus a couple Thou. You may want to thin them at the same time. Most Tractor or Trucking Supply places should have them. Good Luck, Willy T.

I know this an old thread, but I wanted to make a comment.

I just received new genuine part# 11A109 Federal Ski washers for my Cub from Wipaire. I'm sure they were more expensive than some of the above suggestions, but they weren't that expensive at $9.08 each. They are the correct part number from the Federal Ski installation drawings, they are heat treated, ground all over, CAD plated, and FAA/PMA approved. That is not a bad price for special aircraft parts these days.

To me it was a no-brainer to buy these washers from Wipline. How much time can you afford to spend looking for washers, and then possibly modifying them, just to save a couple bucks? I'm confident these washers from Wipaire are better quality than the cheaper alternatives at little extra cost.

I think it also makes sense to buy these washers for another reason. I'm not sure how high the side loads on ski mounts can be, but I feel a little more comfortable knowing the washers that retain the skis on my Cub are not made from mild steel. When the snow is rough, and the skis and gear take a pounding, I know that my washers should do their job without any concern of damage.

P.S. - I do not work for Wipaire. I'm just a first time customer.
