Touring setup with HDPE riser project and testing

[jjue]

Hi Ruben, all my HDPE projects used 1/2 inch thick HDPE blanks which were available stock at my local plastics store and I have had no issues with breakage or excessive flexing with that thickness. 0.5 inch equals 12.7 mm . I guess if you are noticing flexing at 10mm I would recommend trying a HDPE blank with some increased thickness closer to the 12.7mm I use.
Good luck.

Hi Jack,

Thanks! That is some useful information from experience. Here they are available in 12mm and in 15mm, so I guess I will stick with the 12mm then. If others have something to add, feel free to do so!

Conclusion of the test: 12mm thickness works way better than 10mm. I noticed a lot more rigidity in the connection to the skiboards, they give a lot more feedback now. I barely noticed a difference between spruce risers and this setup. The only weak point that I found is that there is still a lot of flex in the HDPE when putting the heel part of the binding into tour mode. This requires a lot of force, so the HDPE will also flex a lot when doing this. However, you can also push down on another part of the riser/binding, eliminating this as a problem. Overall very happy with the setup now! We had a nice tour through medium-deep pow with it and they worked perfectly in both up- and downhill. Also very satisfied with my drilling skills: my accuracy is improving .

Glad the 12 mm riser thickness worked. Congrats on joining the very small clan of ski touring skiboarder!
