I started the evening build on page 21-09 and completed steps 2-5 in about an hour. As usual, the deburring took about 1/3 of this time. Riveting the bulkhead caps in place was straight forward. I took the advice of others and taped over the holes that were NOT to receive a rivet. I think this is a good strategy compared to using a marker.
Installation of the rollers (step 5) was also easy. The only question I have is how much to torque the bolt. I took care here so as not to strip the nut plate as well as making sure that the roller still rolled. (I don't know, but I think the nutplate has a natural tendency to act as a locknut.)
Then after dinner, I completed steps 1- 3 on page 21-10. At least 20 minutes of the time was spent scratching my head to figure out what was called for in terms of MCS the rivet holes. (I'm learning a lot here but loosing hair!) Deburring was thorough to be sure the parts matched and fit well. My biggest challenge was counter sinking the rivet holes. Before MCS the actual part, I test the depth on scrap material. Still, sometimes the countersink is too deep, while other times it is perfect with no change in the cage.
