Runner Explained

Sorry for the poor images of the runners.  Just couldn't get them to photograph clearly at all.  Awkward, too.

Anyway, you can hopefully see that they are made up of three sections.  The sizes of wood differed of course dependent on whether I was mounting standard comics, UK comics or Treasuries.  Mostly, I tacked the three sections together from the rear, so that you could not see any tacks.  The Treasuries were trickier and I had to tack front and rear to make them hold solidly.

Anyway, the base section is the section that attaches to the wall.  It must extend out beyond the holding part at the front so you can hammer the tacks in, so it's the biggest sections of wood.  This part of the runners and the tacks used to hold it up against the ceiling roof are obscured by the comics normally.  (I removed a Treasury so you can see.)  The middle part is the thinnest and on top of that I connected the holding part, which is larger than the middle section but smaller than the base section.  This was a little tricky as you want this part to reach out enough to hold the comicbook at the top and bottom but not obscure any of the front cover art or blurbs.  The base and middle section were just wood sections with squared-off edges.  The front part is the only part you really see, so it was rounded on the side facing inwards and I took care in choosing this wood.  The runner ends up like a sort of 'U', except one leg is longer than the other.

When mounting one row of comics you just repeat this format twice, one with the 'U' facing down and one with the 'U' facing up .  However, when putting up multiple rows, I used a slightly different system for the runner sections that had comics fitted above and below.  Middle runners are more like an 'H'.  Again, the holding part is not as big as the base section that holds the runner to the wall. 

Hope that is clear!
