I would be interested in a little bit at 1/3rd that price. :| The only way to get it at that price is if you could pick up at the factory in France. Then you would still have to get it back to the States. At about 25 kilo per 100 meters I think you would run into some over weight baggage problems. ...

Here is my pre-bender. I am not sure it quite does what I want. It just raps the edges and base around the wheel. It does bend them but not in the same manner as a slip roll. Hard to explain but it just seems different. http://i1134.photobucket.com/albums/m602/monkeyshowpictures/ski%20building/IMG_0...

Another problem I was having that could have contributed to this was the Tuning of of my PID controllers. I had both my blankets controlled by one controller and my second controller as only a monitor (Happy monkey style). Because of this I tended to get high temps (200F+) on my bottom blanket. So i...

nice one on solving this! but doesn't that big of a difference in top and bottom heat cause a lot of change in camber/rocker? It might, the skis I just made were flat under foot, rocker tip and tail. They still came out flat. I'll see when I make a camber skis if they end up with too little camber

I think I solved this. Pre-bent tip of base/edge and reduced the bottom heat in relation to the top heat. Pressed skis at 55 psi, top heat heat at 150F and bottom at 115F. Removed after 30 minutes of cook time. No cooling in press. Flat bases throughout. I had been pressing at between 175f and 200F,...

Sammer, yes I get some of that, but it continues back through the early rise (20cm or 40cm). Did you have more concavity further back on the ski and ground it off or was it pretty flat after the tip? I actually made some skis with a extra patch of glass cloth in the early rise portion to take up vol...

Ok everyone take a deep breath. Brazen, I understand the concept of non compliance and have actually done experiments where I forced only the base (with edge attached) into the tip shape by hand. This produced a concave base. What I want to know is if the problem can be solved by actualy pre bending...

That is an interesting idea Vinman, I do not have different top molds for use with my early rise tip blocks. I have tried a lot of different pressures though so it would have to be the progressively increasing pressure into the tip not the amount of pressure itself. Brazen do you prebend the early r...

Concave Bases on early rise

I am getting concave pockets in my bases in the early rise portion of the ski. I have a 20cm early rise tip block and a 40cm one and it happens on both. Bases are flat through the middle of the ski. I have top and bottom heat and top cat track. I used to let skis cool in the press but following Blac...
