The objective is to create ACE coach roof destination boards that are portable, thus enabling the boards to be removed so that the coaches can be re-deployed for other train formations.
My previous method looked good but with a small sticky area had the tendency to peel with changes in ambient temperature. I also think the stickiness would wear away with use.
My latest method uses roof saddles to hold the boards in place without the need for adhesive. The boards are made as previously described except the label covers the entire backing plastic.
We need transparent saddles to disguise their presence. Take a 1 litre 'High Juice' drink plastic bottle - mine came from Lydl. The curvature is almost the same as the Backmann 00 Bulleid coach roof. Slice through the bottle to extract a ring. Cut from the ring two strips 34mm long and a few mm wide. Using pliers bend the ends to an angle of about 60 degrees and about 3mm long. These are tabs to which the roof board is glued. This plastic takes bends very well.
Place masking tape across the roof width alongside the boards end brackets. (This is to protect the roof from the glueing process). Place the saddles and hold down with more masking tape.
Offer up and hold a roof board against the bent tabs and carefully wipe some liquid plastic glue with a brush into the joins. Repeat for the other side. When set, gently remove the masking tape from the saddles and lift off the assembly. Remove the tape from the coach roof.
The assembly fits snuggly on the roof with the angle of the board looking correct. The whole assembly is quick to apply and remove indefinately. The plastic saddles are glossy which tends to reflect light giving their presence away. Might be an idea to paint them the same colour as the roof.
