Derf Posted November 2, 2006 Report Share Posted November 2, 2006 The moment some of you have been waiting for has come: I got a digital camera (my friend's old one) and took some pictures of the mod I did to my Catek OS1 last winter. I call it the Spider plate. It is essentially a plate that goes between the set screws and the disk. It prevents the screws from digging in the disks. I got the idea when I saw the OS2 bindings. It is made out of stainless steel, so it is as hard as the screws. What it does is distribute the force over a wider area on the disk, preventing the screws from digging in. Since the OS1 were not made for that, I have to tighten the set screws quite hard or else the top wll rotate. It happened once on the first day I tried it, but after tightening the screws a little more, no problem. I have some short plates (3/8" thick compared to 1/2" for the long plate), so they bend a little, but not too much. I was told it is normal, even regular OS1 do it. Here are some pictures: Quote Link to comment Share on other sites More sharing options...
Fleaman Posted November 4, 2006 Report Share Posted November 4, 2006 That thing looks pretty cool Derf, I would assume you had acess to some equipment to make it. could you cut it out of a plate with a jigsaw? Quote Link to comment Share on other sites More sharing options...
Derf Posted November 4, 2006 Author Report Share Posted November 4, 2006 I work in a place specialized in sheet metal, so I have access to an Amada CNC punch and a sheet metal folding machine. It would be pretty hard to cut stainless steel with a jigsaw, especially a small piece like that at the thickness used (16 gauge = 1/16"). You could try aviation snips (I think they are called that), but on material a little thinner, like 18 or 20 gauge (0,050" and 0,037" respectively). I plan on trying thicker and thinner materials on other prototypes this winter to see what difference it can make. Quote Link to comment Share on other sites More sharing options...
Kent Posted November 6, 2006 Report Share Posted November 6, 2006 I'm confused.....what problem is your spider trying to solve? Quote Link to comment Share on other sites More sharing options...
alexeyga Posted November 6, 2006 Report Share Posted November 6, 2006 Derf, Imho, this solution is rather arguable... You solving one problem but you’re creating another one... Plates aren’t the only thing flexing there.. Your center disks are really going bananas as well... Quote Link to comment Share on other sites More sharing options...
Derf Posted November 6, 2006 Author Report Share Posted November 6, 2006 I'm confused.....what problem is your spider trying to solve? A couple of problems (that have been fixed in the OS2). 1) The huge holes created by the screws. Other than being ugly, the holes are not practical when you decide to change your angle by 3 degrees and the two holes beside the original hole are almost unusable. With my plate, no digging in. 2) The "settling effect". When you first set your angles, the screws have not yet dug in the disk. You do a couple of runs, they dig in, you tighten them, and so on for one or more times. With my plate, no digging in so no settling effect. I think it is something to do with dimpling the plate and having 3 degree adjustments... Yes for the dimpling, no for the 3 degrees. 3 degrees is enough for me, I used to have Burton plates. Derf,Imho, this solution is rather arguable... You solving one problem but you’re creating another one... Plates aren’t the only thing flexing there.. Your center disks are really going bananas as well... The plate is bending because of the leverage: the screws are 2" from the center and the top plate is 3/8". The disks don't bend as much because the screws are 1" from the center and the disk is around 3/8" thick, so half the leverage. The pressure points stay the same, and when riding, the forces exerted are quite big, and the disk are made to withstand this. Quote Link to comment Share on other sites More sharing options...
alexeyga Posted November 7, 2006 Report Share Posted November 7, 2006 Yet, I think that the most elegant solution to this "problem" lays on the tip of these set-screws... But I don't see it as such a big problem to begin with, just keep them tights and they will outlast everything else that could break on these bindings...

Derf Posted November 19, 2006 Author Report Share Posted November 19, 2006 I put the higher resolution pics on my website here: http://derf.dyndns.org/~derf/gallery/snowboard_catek_olympic_spider I also wrote to Jeff to see what he thinks of it. Maybe I'll just go back to the normal installation method after thinking about it... Quote Link to comment Share on other sites More sharing options...
