Ron Pybus ...Thanks Jas. Was the 7mm softwood ply? <br /><br />Ron Pybus in his book suggests 6mm, but he talks about it being exterior grade hardwood. <br /><br />I have looked at both at the Big Green Store and from the reading I have been doing it would appear that the softwood is more susceptible to warping, hence my follow-up question.<br /><br />Thanks for answering, I would have lent towards 12mm myself but would like to be able to move this around so weight is a consideration.<br /><br />Merry Christmas too!<br /><br />Bob.Anonymoushttps://www.blogger.com/profile/10763355426005502457noreply@blogger.comtag:blogger.com,1999:blog-2433568508521117006.post-71202201615773420282018-12-15T16:26:53.706+11:002018-12-15T16:26:53.706+11:00Hi Bob,

I wouldn't use it again, as even with 600mm centres it was still warping.<br /><br />I now use 12mm (5 ply) plywood and haven't had any issues to date with it. 18mm is just overkill and make installing feeders, signal wires and tortoise fulcrums harder.<br /><br />Jas...JLandT Railroadhttps://www.blogger.com/profile/09505164174036992414noreply@blogger.comtag:blogger.com,1999:blog-2433568508521117006.post-34319685319686581482018-12-15T12:54:17.791+11:002018-12-15T12:54:17.791+11:00Hi Jas,
