Question x posted to uk.models.rail and rec.models.railroad
I am making an HO American outline model. Having read up on various ways of making roadbed I am now experimenting with cork.
I have purchased some cork tiles from B&Q (Home Depot on the US) I have managed to get a semi 'production line', using a paper trimmer, to make strips 20mm (just over 3/8") wide. This approx. half the width required for a single road and is what I've seen suggested [1]
The problem I now have is how to make some sort of 'production line' to make the shoulders (1 side of each strip) to roughly 45 degrees so that I do not use too much ballast.
I have considered trying to lay the cork first them shape it, but I know from previous experience it will always be in most difficult places to reach and so would like to do as much 'on the bench' as possible beforehand.
I have considered (but not yet tried) using my bench grinder and running each strip *lightly* down the smoothest side but don't know whether this would clog up the grinder too much or would cause the cork to burn too easily (I did say lightly!!)
Does anyone else have any suggestions?
[1] 2 x 20 mm strip have the advantage that you can just draw a centre line, lay one alongside it, then lay the second to that. It is also easier to bend than anything thicker would be.
