I thought I'de upload some pics of a homemade ski rack I just made just incase anyone was thinking of doing the same..
Pretty simple in the end I got a couple of bits of alloy from alsco and some rubber from hammer hardware drilled a couple of holes popped a couple of rivets and that was that, cost me probably about $60 ($400 for a thule skirack) Of course I did already have the roof rack..
I'm going to add springs so they pop up automatically and I may fit thicker foam to accommodate different amounts of skis/boards better
I hope this help anyone thinking of making a ski rack just in time for the end of the season haha... oh well best intentions...
