Step 1: Lay Out Base.
Place the center cross member in the middle of the skis or other base pieces. Position the other cross members 14 1/2" from the center cross member.
Drill countersunk screw holes on the bottom of the skis or other base where the cross members attach. If you use skis, scuff up the slick tops where the cross members are screwed and glued. We used Elmer's polyurethane glue and decking screws.
Step 2: Drill Holes in Center Cross Member
Next, drill a 1" deep hole the same diameter as the ski pole or other vertical support at each mark. We drilled eight holes using a 3/8" bit with a masking tape stop at 1" for our bike rack. You can modify the design for more or less bikes.
Step 3: Drill Holes for Upper Horizontal Support
Step 4: Install the Vertical Supports Through the Upper Cross Member
Now line up the upper cross member with vertical supports installed with the holes in the bottom cross member. Tap into place.
Level the upper horizontal cross member by tapping here and there.
You could install the vertical supports one at a time into both the upper and lower horizontal cross members, but we didn't.
Step 5: Park a Bike to See How It Looks.
Step 6: Attach Bracing to Upper Cross Member
Check out my brother in law Rusty's huge ear holes (1 3/8") and lip rings.
Step 7: Park the Bikes
This bike rack doesn't provide real security for locking the bikes up. You could lock all the bikes together and that would help. I just wanted something to keep our bikes upright. We keep it in the backyard and don't have much theft in our neighborhood. I usually cover it with a tarp in case it rains.
If you left it out it'd be a good idea to place it next to something that you could secure the bikes to.
