Step 3: Drill holes and assemble
When you're finished drilling, keep the clamps in place and insert the bolts. Be sure to use washers on both ends of the bolt. I used a mallet to pound the bolts in, which helped speed up the process.
If you need to take the bolts out, don't make my mistake of hammering them out from the threaded end - I ended up ruining several bolts by hammering the threads away, making it impossible to screw the nut on.
