Anyone tried 3/16th UHMWPE
« on: November 23, 2016, 11:33:00 am »
So 3/16 plastic is about 15% cheaper and of course lighter and it will roll up easier. I think it will work fine given my experience with 1/8 but I guess I'm looking for some peer group input.

Did you ever try the 3/16" UHMWPE? If so, how did it work?

I used 3/16 but was reluctant to countersink to the depth for conventional bolts so went with chicago bolts which aren't as strong. Otherwise it has worked out just fine and I belatedly decided the material is likely strong enough to support countersinking for a regular bolt head.

I used 1/8". I found the material wanst even close to stiff enough, and everywhere you lashed the gear, it pulled the toboggan up and made the whole toboggan undulate, and be wavy. Made it a bit hadred to pull over logs etc since the bottom wasnt really flat anymore.

I imagine 3/16 would be a better compromise.

Sled material does not get any lighter than a crazy carpet so I put in cross pieces side to side at each tie point. I used it a lot without the cross pieces by putting my sleep pad and any thing else that had an edge so the sides would not be so wavy. The cross pieces keeps the edges straight.

Yes, see this post.

It works fine I think.

To go thinner and use 1/8th you need to put the cross pieces close enough together that the lashing only link to the toboggan at the cross pieces (Q: are these thwarts?) That way they don't bend up the plastic. Almost makes the running lines redundant apart from at the curl.

Both 3/16th (4mm) and 1/8th (3mm) take a countersunk #8 fine.

Perhaps I am just lashing my stuff down too tightly. A must when your sled goes rolling down a hill... ::)  Using the usual 16" spacing for the toboggan, it makes the sled work poorly.


I am making a pulk style sled soon just to try, out of 1/8"so that will obviously solve the issue so long as I like how it tows. I made one of the northern sledworks clones for behind the snowmobile for trapping. It was a massive success and works incredibly well for hauling up to 800 lbs behind the sled .

By now I have made about a dozen toboggans/ pulks, so hopefully the new one will be the last...

yea right.
