Ski Builders Forum

hello,i`m new to this forum,and have a little question.i already build some skis over the last years.they are all pretty good,thanks to this forum and the tons of information.thanks.at some of them,i noticed a very little delamination,just about 4mm,exactly where the tipspacers meet the sidewall.it just happens when i bend the ski nearly to the limit.also its just the topsheet that delaminate,not the glaslayer.itried to fix this by laying up vds over the sidewall and tipspacers,didnt work.could this happen because of the little bit of hotglue at this point from fixation of the tipspacers?or is it maybe just the wrong place on the ski for this point,to much load?any thoughts and sorry for my english.

My guess would be the hot glue.

I use porous paper tape, like first aid tape to attach the tip spacers. I also make sure to keep it well away from the edge of where things will get trimmed.

pics tell the tail. Tough to know without seeing it.

poor pressure at that area. This is a common problem, and is the reason that some presses have rams at the radius point to assist the laminate in making that bend.

thanks,for the replys.try to build another one this weekend,without the hotglue.try to make a pic of the delamination.i think it`s not the press,because on one ski it was just on one side,at another both sides.maybe i`m wrong,keep an eye on that too.thanks again
