Hi Lee
Another useful supplier for most modelling supplies is
https://eileensemporium.com/
They sell bass wood stringers in all sizes.

Hi Dave will have a look on there site regards lee

Hi mick Thanks I’ll pop in to b q and have a look she gonna be a 1/12 scale. Regards lee

As to where you could get it from. Cornwall model boats sell a good selection of wood for building or decking. including a lot of nice exotic timbers which will give lovely decking patterns. As to what. I would use 1/8th inch or 1/4 inch square for the stringers in spruce. Hope that helps. Kindest wishes, Dave W 😊

Hi again,
I think most large DIY stores such as B and Q,and Jewsons etc have a section where you will find a rack containing many types of wood mouldings etc.That is where I would be tempted to look.They come in decent lengths,as well which is ideal for your use.By the way,what scale are you building her in?Anything less than 1/12th or 1/16th,that size may be to large and heavy for you.
Good Luck

Hi thanks for the reply any idea the best place to require the wood from? Lee

I would use the old measurement quarter inch by quarter inch ramin.
