Ply Thickness
« on: January 15, 2008, 05:15:44 PM »

I have started to buy materials to construct Vic Smeed's "Star Baby" R/C yacht. The plan calls for the hull to be ideally covered in 1mm Ply, but as an alternative, to use 1/32" or 1/16". As 1mm ply seems to be difficult to come by (or do you know different) , I am contemplating using one of the alternatives. Before I buy, I am curious to know what the advantages and disadvantages of each thickness may be. For example : thicker means stronger but heavier and visa versa, will the buoyancy and handleability be affected?, would the thicker material be safer for an inexperienced captain. What does the "team" think??. Thanks. Barrie.

Hi

Look at Mobile Marine Models for thin ply. They list 1/64 (0.4mm) 1/32 (0.8mm) and 1/16 (1.5mm). You would be OK with the 1/32nd instead of the 1mm. 1/16th would probably be a bit heavy.

I built a Wee Nip yacht using 1/32 (my local shop doesn't do metric  :o ) and have had no problems. Whilst 1/16 is going to be stronger it is surprisingly resistant to bending to the required curves.


Wee Nip to the right

Many thanks to Barrie and Doug for your valuable advice. I was already leaning towards using the 1/32 ply , but I wasn't sure which would be the best. Thanks again for your input.
Regards, Barrie.
PS. Wee Nip looks great. Must add it to my "want to build" list !!!!!
