Midwest Cork roadbed centerline

I know there have been lots of roadbed topics - here's one that I haven't found.  Midwest cork roadbed splits off-center (this isn't new, of course).  When you separate the two pieces, one is wider than the other.  So - if you glue them down along your track centerline, it will be off-center, and if you lay your track along it's centerline, the track will be off-center on the roadbed.  I can adjust for all this of course - the question is, should I bother?   I'd like to know what others do.

I'm sorry Dave, I'm afraid I can't do that.

I don't adjust for it. I just use the centerline.  With the smooth cut placed to the viewing angle and the ruff cut side to backside or center of a double tracked mainline.

Well before I lay any track down on cork I spend a lot of time sanding it down and rounding off the rough edges.

Hadn't given it much thought, since I use flex, and don't have any perfectly specific radius.  I did note that around my wye, things got a might skewed off center, and maybe this was the reason.....or, I laid the track out just off what the actual geometry might do.

I suppose you could lay to the right or left edge, depending, just covering the sharpie line. When it disappears, put the narrower side down on the other side.

Midwest cork is too wide compared to most prototype subroadbeds. I used to cut the wide side down 3/16" to get a better width. Now I just cut my own roadbed from sheet cork. That way I get what I want and it is cheaper.

Either wa I sand the cork with a palm sander and wrasp the shoulders so they don't prodrude through the ballast later.
