guys, where is best place to buy uhmw plastic in white for skiis? Need to put some plastic bottoms on our aeronca sedans skiis.
I was going to go 2-1/2 inches wider all around and heat and brake side ups and tail up at 15-20 degrees. However it makes me need a 13-14 inch wide x 6 ft5 pieces.
ideas?
thanks again

Do you have any local shops that sell dog-mushing supplies?

thanks mtv, are you guys piecing the bottoms? Seems like all they want to sell is 4ft length.?

Definitely interstate plastics. These are prices I got from them or year ago. 10' x 4' sheets. The weight per square-foot differential might have you thinking to go the 1/8 inch thickness which is great for simply mounting to the ski bottoms without overlap. If you are going to extend the bottoms more than about an inch, you need to go with at least the 3/8 thick which will allow you an overlap of 2 inches. More overlap than 2" and I would recommend the quarter-inch .

thickness _ lbs/ft2 ___10'x4' sheet___ $ / sq. ft.
0.125 _____0.630 ___$147.00 ___ $3.68
0.187 _____0.940 ___$197.32 ___ $4.93
0.250 _____ 1.250 ___$220.00 ___ $5.50

I assume you mean 3/16 Matt as 3/8 is thicker than 1/4.. Anyway 3/16 should b the thinnest you use even if not extending, 1/8 gets loose and starts to "bag" and will eventually split and become an anchor!

Yep, 0.187, 3/16. Tried to correct it in my discussion, but wouldn't let me edit once I had posted. The 1/8 works fine if you don't have much of an expanse between skegs or other rivet lines. I use it on the hydraulic plates that cover the wheel openings on my FliLite 4000s without any problem. My Aeroski 2800s and 3000s had 1/8" on them for many years without issue, but when you play harder, the thicker plastic lasts a little longer when operating in marginal (read poor snow cover) conditions before requiring recover. I would agree though, if you have a wide ski with just the edges tacked down the thinner plastic will develop ripples with faster wear at the peaks of these.

Check your local hardware store. Here (Canada) they call it puckboard, used for sideboards on hockey rinks. All thickness and 4x 8 sheets.Not expensive as I recollect.

Puck board is not actually UHMW and is not nearly as tough.
