It seems to me that the most interesting part of ski and snowboard manufacturing is the work with wood. We decided to make of first snowboards from poplar since it is not hard to find this tree in our country. Also many people advise to start with poplar. But still, really difficult to select approp...

After collecting all the items in a bunch, we began testing the press. The first test passed without a hitch. At 50 psi the deflection in the middle between upper and lower I-beams was about 12 mm. I didn't imagine that I-beam with such cross-section can be elastic under 50 psi. Compressed air makes...

One of the difficult stages was associated with the construction of an air bladder. It was difficult to find right fire hose. First we decided to purchase it somewhere in Europe or in USA but the freight was too expensive. So we decided to buy one in Ukraine. We were not sure in the quality and stre...

Before start working with moldings we had to create the model of the first snowboard. The scientific work of Ka Wai Lee "Full customisation, quick performance estimation and optimisation of parametric snowboard design" helped us a lot in this. So, we fell into work with wood. The first ste...

A little cut sides of the ends of I-beams to reduce weight of construction and warn cut on the sharp edges of metal and then apply some yellow paint to prevent corrosion.

Afterwards, installation once more.

After some tries to make an ideal holes arrangement we finally installed all beams into place. http://s10.postimg.org/o13itsxol/2015_05_21_20_25_25.jpg http://s7.postimg.org/ttp1vac7r/2015_05_22_21_00_33.jpg bolts of strength class 8.8 or higher are welcome We have calculated that bolts of diameter ...

If in the previous step metal could be cut right and left, the bolt holes required special accuracy. We faced some difficulties on the stage of drilling holes since we have tried a few methods. The first one was a bit crazy and material consumptive. We used a hand drill. We drilled holes gradually f...

The next step was to work with metal. Metal cutting and stripping took some time. Good angle grinder in this case, is the best friend. http://s3.postimg.org/gf0vgf373/image.jpg http://s14.postimg.org/eqc56nmt9/image.jpg http://s29.postimg.org/ggvez5577/image.jpg Work is not the most difficult and do...

Having defined the type and design of our press we performed some calculations to obtain the results of stress and displacements. And in the result we chose cross-sections of future I-beams. http://s16.postimg.org/wz125xzc1/Nws99_QOb_PQ4.jpg http://s27.postimg.org/rmjikm3i7/Fl_IFN1_RSIe_E.jpg After ...

Through the thorns to the stars

Better late than never. We have started to work this spring (2015). The first thing was to decide weather it is possible to start manufacturing snowboards in Ukraine or not. On the one hand there were lack of materials and unfavorable economic situation. But on the other hand it was sweet to thing t...

try to find right epoxy on the market

Hello, my question is about the epoxy. I have read that the majority of people use EMV-0043 epoxy. Also CPM/CPL heated compression resin by Entropy Resins is good. I try to find same kind of epoxy in my country but its all in vain. The only one thing I have found glue on the basis of epoxy that I ha...
