michaelp Posted February 7, 2014 Share Posted February 7, 2014 I am going to build a new layout but instead of using MDF this time I am going to use 9mm exterior ply, will this plywood be okay and because of the plywood is made do I need a special blade for my jigsaw to cut it? Thanks in advance. Michael Link to post Share on other sites More sharing options...
Mythocentric Posted February 7, 2014 Share Posted February 7, 2014 Hi Michael 9mm ply is fine for the job with Birch ply being first choice. If you are using ply throughout cut the sides and ends between 100 - 150mm deep which will form a rigid box. You may have problems getting a straight cut using a jigsaw (finer blades better) without a guide so having it cut by the providers would be better if you don't have access to a circular saw!

RMweb Gold chris p bacon Posted February 8, 2014 RMweb Gold Share Posted February 8, 2014 Hi Bill, Thanks for your reply, is Birch ply different to exterior ply? Michael Birch ply is a superior quality ply that is dense with no voids, very good for making baseboards from. Exterior ply is any ply that conforms to a BS number (can't remember) and is suitable for exterior use when treated correctly it is possibly far Eastern or Chinese nowadays. Of the 2 Birch is better, recent prices for 9mm were Birch £28 per sheet, Far Eastern £16 You pays your money and takes your choice. As for a jigsaw blade, use a fine cut one to reduce the splintering and don't push too hard on the jigsaw, let it set the pace of cut. Link to post Share on other sites More sharing options...
wirey33 Posted February 8, 2014 Share Posted February 8, 2014 Get your timber supplier to cut it for you. Link to post Share on other sites More sharing options...
Londontram Posted February 8, 2014 Share Posted February 8, 2014 When I cut mine using G clamps I clamped a length of 2 by 4 timber along the length of the cut taking into account the width of the jigsaws foot/guard and kept the jigsaw up against it as I made the cut this helped to keep the jigsaw on the cut line, a fine wood blade cuts the chance of splintering too. This gives you a fair chance of a straight cut if you dont have access to a circular saw. Seve Link to post Share on other sites More sharing options...
