hi all
this might be a silly question but what would you folks recomend to use as the wood filler? does it need to be flexable to allow for shrinkage. I am going to paint the model so it needs to be able to take the paint.

Many use offcut saw dust with PVA

In all my joinery, if filler is required I tend to use 2 part ronseal wood filler as it is strong. However quite often, especially if colour matches are required then you can't beat the aforementioned sawdust and pva, just apply pva to area to be filled and then sand the surrounding area to auto mix the sanding dust created with the glue.

Either I would say would be perfectly good for this build as would the filler recommended by Mr T.

However I couldn't say I'd risk using polyfiller. Its not really designed for wood, definatly doesnt flex and will over time crack and probably fall out. I don't even use polyfiller in walls and I don't think its very good.

Sorry my 2p!

thanks everyone for the adivse i will give them a go dont get me wrong these are only small gaps to be filled, as it took me 3 attempts to get the planking right.still not completly hence the use of filler.

try thin slither of wood if you can see through the gaps , plane or knife cuttings etc and sand down after thats what i do

Just to clarify my earlyer post i said 'some ppl use poly filler' but forgot to add but i wouldnt recomend its use

I have tried mixing wood filler (wilkinsons home brand) with 50/50 PVA with good results.

Some fillers I have used in the past tend to fall out of the smaller gaps when sanding.

Thanks MWG I will bare that in mind when I treenail the Suprise.

Just say your recycling the dust m8
