Page 12 of the “6-B-21B” photo guide shows that the edge of the skin is wrapped around the tube. This works best if you minimize the edge distance. As it says in the guide “Wait to bevel the front edge until after the skin is riveted”

I recall one builder relief cut slots (with stop holes at their back) between the rivets to minimize the ripple.

Tapped it with a rubber mallet.

I assume this is a reference to the forward edge of the top  skin, just aft of the cockpit (6F14-2 on my 601HD/HDS drawing).   If so, the following may be helpful.

  

 I made relief slots which are actually more like  wide notches with the notch the same depth as the rivet edge  distance.  My rivets are spaced at approximately 50mm.  The  notches are tapered at about 45 degrees, so that the tab containing each rivet  is about 30mm wide at its forward edge.  The tabs are rolled  smoothly around the tube. As I remember, I formed the tabs before I rivetted the  skin in place, so I could "over-bend" them a little bit for a tighter  fit.

  

 If I were to do it again, I believe I would not roll the skin,  but simply finish the outstanding edge with a molded U-channel, ACS p/n  05-01400 or something similar.

I did not have the foresight to anticipate how unsatisfied I would be with tapping that free edge down to the tubing contour. Afterward, I knew that I would never be happy looking at that result everytime I entered and exited the airplane. I bought some automotive radiator hose, cut it length-wise and slipped it over  the ugly edge. It has to stop a little bitshort of the bottom on both sides to avoid interferring with the canopy but I can live with that. Now I have a decent looking rubber molding to conceal the middle top skin's forward edge... problem solved.

Scott Laughlin had a nice solution for this. Unfortunately he shutdown his web site, but maybe he'll comment on this thread...

To minimize the dreaded "buckled edge" on the roll over:  double the rivets along the edge, ie. every 25 mm, and cut the edge distance to 7mm.  Use a rubber or plastic hammer and go slowly. (picture attached)



This same philosophy works at the longeron as well.
