Step 6 Attach blocks to ski

Now its time to screw the blocks onto the skis. First, you'll want to decide how far back you want your blocks. With 24" skis, I decided to put the blocks 6.25" from the back edge of the skis. This is mainly a gut feeling call. However, my design allows for the fore/aft position of the axle to be adjusted after the fact (within about a 4" window) so its not incredibly crucial.

Position the wood nice and straight under the ski and clamp the thing down. Lay out and drill the holes through the skis into the lumber. Now get out your handy countersink bit and countersink those holes! Test fit a screw every once in a while until you get the head just below the surface of the ski. Use a knife to trim off the excess melted plastic around the edges. For this step, I used standard 1.25" drywall screws.

Line up the next block on top of the first and clamp it. Drill holes for 4 screws to fasten the blocks together, making sure not to drill into the same place you put the previous set of screws. Any screw long enough to fasten just the two blocks together securely will work, I used 2.5" drywall screws. Repeat until you've got your 3 or 4 block stack completed.
