Regulatory signs...OH BOY ! As you can see by the signs on my cutting mat...these signs are about 1 inch in length...including the thin plastic posts ! Where the problem lies is the posts themselves. They are plastic and about the width of the lines on the cutting mat ! I broke about one in 3 posts just sticking them in holes drilled on the layout. Later...when I vacume the layout or even dust it off....I will most likely break off and suction up every one of them that survived. Surely there had to be a solution ! I have a spool of .025 Mig Welding Wire. I cut 1 inch lengths. I sanded off the plastic posts from the signs I already painted. I glued the mig wire where the plastic posts where. I then had to repaint the posts The rest of the signs I will 'fix' the post problem before spraying them ! N scale...love it...hate it...LOVE IT !! .
