Well. After first "building" season I have done the second. I had some experience from the first and tried to implement it this summer. I wanted to get as flat bases as possible and to get cca 5-8 mm camber in my skis. So I made mold with 10 mm camber end expected decreasing of camber like...

Hi all there. I finally fixed the leveling with regular concrete. I made rails along the whole surface and spread the concrete bwtween this rails. I set the rails exactly with leveling device (geodets use it). then I placed two 3 mm iron plates over that concrete and then two MDF plates (21 mm) over...

thanks for suggestions. I was also thinking about flooring epoxy resin but it is very expensive in here. The strength of flooring epoxy against pressure is 21 MPa cca. My cemment concreet is 25 MPa and the price is absolutely different - much much cheaper for me. I want to use layer cca 15 mm. I do ...

The plates will be there only as smooth spacers. Maybe not necessary. But level surface should be ensured from the concreat layer... I hope, we will see :)

Hi guys! The press is welded now. The surface is not as perfectly flat as I planned, some I beams twisted a bit, so I am going to try to fix it with self level concreate layer (cca 1.5 cm thick). And there will be 2 layers of 3 mm thick metal plate. I think it should be almost perfectly flat then :)...

hi, I agree with pmq - 15 mm camber - that is huge! Even 10 mm per ski is quite a lot. How long is your camber and how long is the ski?

Thanks for all advices! That self leveling cement looks very cool. Ff it goes too bad, that could be my last rescue :) But maybe it would be better to use thicker layer, or would not?

I ve used 2 composite Pu exterior coat (for yacht) called Perfection Plus with 8 year warranty... Should be good lack. But maybe the oack veneer is not the best for varnishing. One of my pairs is epoxy coated with those lack above. Will see how it works. Another are only veneer topcoated with PU

well, my father has some experience with welding and building iron constructions, so when my parents asked me what I want as a christmas present, I said nothing but I would be grateful if my father helps me with the press frame. :D I am so modest son.... So that is our vision of the ski press (sorry...

Ski press - perfectly flat surface

Hi there! I got some older "U" an "I" beems for free and I decided to built a new ski press from them - more comfortable for loading cassettes (classicaly from side). I was thinking that irons should be flat and right angled itself but unfortunately it is not true... Even in an i...

The red spots look originally! Conditions there seems to be like there is not such a need for fat powder skis but some BM could be fully used there :) I like spring snow. If it is not too wet, it is comfortable for fast technical skiing and even allows to drop something bigger (that is possible to s...
