the original plan is for the baffle and the flare sections in 12mm. the baffle is a double so it ends up as 24mm..

no harm at all in making the flare from thicker material.. once the internal size is the same you're good.
i drew it all out in CAD myself just to completely familiarise myself with all the parts.. they turn out marginally different to the dimensions on the plans i think. worth learning some CAD for stuff like this.. but 2d cad can't work out the compound mitre angles for the vertical flare bits.. i think i just went at it with scrap bits and trial and error till i had them right (think it's 3.5° or something) if you don't know what i'm on about there... you'll get there..
