Can anyone suggest suitable replacement to the plywood strips used for the 330/300mm long deck beams used in Stage18/19 of Pack 2?

The instructions tell you to make cuts to the rear face to allow for the deck & rib curvature. I must have gone too far in one spot and weakened them because while sanding them down one long and one short one bent so they are now useless!

CS tell me ther is no surplus stock in the UK so would have to come from Italy Crying RollEyes and we all know how that goes.

I thought if i could find a suitable pliable hardwood i can make my own. Any ideas???

Regards

Hello Gray!
If you can get the actual curvature of the beams drawn out on paper I would suggest cutting or sanding a thick strip of plywood about an inch in depth, half an inch or so in thickness and the length of the beams to that curvature and then get some square section wood from a model shop or supplier, the same size as the beams and soak or steam them to make them pliable before clamping the beam to the plywood former along the curve.
Once the wood is dry you should be able to remove it from the clamps and have a wooden beam pre-shaped to the correct curve.
Best of luck!

Thanks for the reply, Robin.

Derek from the FST (delboy271155 - thanks Del- you're a star ThumpUp ) had a spare Pack 18, which he has very kindly sent me. Quite suprisingly, the beams in this pack, which came with the printed booklet, are actually WOOD, not plywood like mine! I think this is much better for me and definately the way to go.
I will try your bending idea Robin - hopefully that should work!

Hi Gray

I`m happy the spare was what you needed.Cool

As for the parts in pack 19, if it`s only the strip wood you need take a look in Cornwall model boats. Enter stripwood into their search engine and they do pages of different sizes.

Here`s hoping.

BigGrin Good shout Del ThumpUp

It loks like the choice is between balsa, beech, and lime to get the correct measurements of the originals.

Does anyone happen to know the properties of these different woods, as to which would be best suited to 'steam bending'?

Lime will bend the best. Balsa is too soft, and beech a bit too hard.

Best,
