It was great to be finally doing the layup that i have been thinking and talking about for so long. It was also the first time i have used the 22oz triaxial fibreglass (usually use ud glass) and when i first got it out of the box i remember saying "man, this thing isnt a fabric, its a rug!'. ahh the good times.
Even though i have mentioned this in the design thread i will say it again for those who arnt so aware.
Our Project, the 'ΓGAMMA SL' as we named it is our 3rd ski that we have built. Hence the greek letter/word for '3' in the name.
The aim of the poject was to build a slalom ski with the aim of carving on ice and hard pack conditions.
Dimensions are as followss
Tip: 116mm
Waist: 65mm
Tail: 100m
Radius: 14m
Tip core thickness: 2mm
Waist core thickness: 10mm
tail core thickness: 2mm
press camber: 15mm
Total length: 165cm
tip hieght 50mm
Tail height: 0mm
tail style: race stock spade.
weight: TBA
overall thickness under foot: TBA but should be about 14/15mm

A full vid will be posted soon. here are some pics of the press.
about the press
It is clamp in nature. The mold is made out of MDF ribs built to the camber specification of the project. so it coveres 165cm and 15mm camber. As we are not really into building twinnies, their is only one tip mold built also out of MDF. All of this sits on a nice T-frame girder.
Ontop of the mold is 2mm thick alluminium sheet which coveres the ribs.
Then the ski is layed up and is then covered with another 2mm alluminium sheet.
A long piece of pine is then used to help distribute pressure more evenly.
the pressure is then put down by 17 symmetrical angle steel sections all pushed down by 15mm bolts. And then a similar contraption for the tip.
The whoel thing is then covered by a custom wood frame with tarpolen, a heated fan is then inserted in one end providing the pressing 'chamber' with an internal air temp of 70ºc.
Here are some pics.
This is the press. (not pressurized)
here is the top of the press with the ski base being glued on.
Here is the heated chamber built to cover the press
making the ski from the template, a 07' fischer sl.
Laminating the sidewalls on. (one at a time)
This thumbnail is of the core, tho i poseted it in the other thread.
Thats all the pics i have for now, we filmed most of it so i will have to briefly edit it first before i can post it. The ski is still in the press as it hasnt been 24hr yet. So i will keep you posted!
schuss
any thaughts?
