Why not use two firehoses as is done in the 'how to' section of this site.

@Mutombo: If you want to I can also host your pictures.
Just let me know!

Hi G-man, Thanks for your reply! Of course I will post a picture of my press under 6 bar pressure. And it's a good idea to create some test pieces, although this might be quite hard, because the edges will close in the epoxy when the system is closed. So I have to build a fully closed test piece I t...

Looking great G-man!! I read you are pressing at 50 psi (about 3,5 bar). Does there squeeze many epoxy out of the skis while pressing? I designed my press to a maximum of about 90 psi (6 bar), so I'm wondering if more pressure will be better (and create a lighter ski) or that it will only squeeze mo...

Found an interesting article using our university database: A Developed Method for Studying the Surface Energy Variation on High Density Polyethylene Abstract: In the gas flame treatment of low surface free energy (SE) substrates, such as high-density polyethylene (HDPE), problems might arise from u...

Superb pictures!
Gives a good vision of what happens after waxing.

I was also thinking that using this kind of microscopic pictures we could maybe find out what is the best way of surface and flame treatment for UHMWPE sidewalls.

Everyone who has the passion of building his own ride should put some love and care in his press and skis! :) I'm sure that will increase the lifetime of both. Also as a mechanical / biomedical engineer I don't like sloppy work. @ Hose-man: Cool that you've been living in the Netherlands. Where did ...

I have been busy last weekend building my press frame. So time for some pictures! http://www.groene-engel.com/Buuk/Skibuilders/5.jpg Painted U-profiles http://www.groene-engel.com/Buuk/Skibuilders/6.jpg Fasteners http://www.groene-engel.com/Buuk/Skibuilders/7.jpg Assembling the press frame http://ww...

I am also busy trying to figure out what's the best way to bond UHMW sidewalls to wood (and gfiberglass). The big problem is that plastics like ABS and UHMWPE, HDPE etc. are plactics with an low energy surface. There are some products out there that will help you to bond the plastic like Loctite Pla...

I am building a press frame using some wood at the moment.
I will assemble it tomorrow, so then I will also post some pics in my building log.

@Mutombo: About getting a smooth running ski / tip. I also use an arc to draw the sidewalls and a spline to close the tips. But I probably create the spline a little bit different as you do. In the first place I create a spline that is connected to construction lines (not a lot of CAD programs suppo...

Check the link below for more info about some 3M stuff to bond low surface energy plastics like UHMWPE, ABS etc.

Hi, Got some more info, but not all I wanted, they misunderstood me and gave me the price for 4 to 5 kg instead of 45 kg... But I got some more info about the exact type of profile. Please let me know if this type is what you need! And please let me know if these are standard/good dimensions, just t...

I am arranging a deal for edges from Austria at the moment, probably with the same company Lindsay from snowboardmaterials gets his edges from. I called the company yesterday and the edges are sandblasted and coated (for bonding), hardness is 48 ±2 HRC (standard in ski industry). These edges will co...
