homemade splitboard

its easy. I have done 3 in the past DOZEN years. Use a skil saw with a metal cutting blade, $3 at the hardware. Make sure you SEAL THE EXPOSED CUT EDGEs FIRST! and let them dry before you mount the hardware or you may be sorry as the tolerances are tight. The kit instructions are straight forward. Make sure not to mount the center pivot too far back or your tip will always drop down when in ski mode, big bummer when cutting switchbacks in deep snow.
Any beater board will do and remember the cut softens the overall flex dramatically so a soft board will be a super noodle on the slopes.

I had good luck cutting one of my boards this summer, and haven't had any problems yet. Here is a link to the steps I took to make it happen............

If at all possible, it would be best to have one board for resort riding and one for backcountry, but you could ride your split inbounds no problems. I just wouldn't want to be putting 40-50 days on the board at the resort. A few days here or there isn't a problem though....
