Edge Gluing Planks?

[turangi]

I recently finished planking the MS Picket boat, about 1/2 way through the planking I realized I should probably be edge gluing the planks so about 1/2 of the planks are edge glued and the others not, only glued to the frames. I wonder if after smoothing the hull if I should apply a thin line of CA along the seams of the non-edge glued planks? I am afraid if I applied it prior to sanding the CA would harden the wood along the seams and make sanding more difficult. Any advice for this beginner welcomed!!

Hi, I think it really depends on the finish you want to apply.   If painting the hull, you can edge glue with PVA or CA but if a clear, stained and varnished finish any glue will more than likely result in a 'splotchy' finish no matter how careful you are as the glue penetrates the wood.

 

More experienced modellers may be able to give better advice.

Stay away from CA.  Always use the PVA except when gluing metal to wood. It seeps into the wood and makes a stain very hard to sand out. Use PVA  {wood glue}. If you have gaps mix PVA with some sawdust of the wood you are planking with and use as a wood putty. If you just want to add strength just wipe on PVA with your finger tip, clean off any excess and sand.

Thanks for the replies! The hull will be painted and some of the joints are so tight that I fear PVA will not enter them hence I thought of CA as an alternative.

I gather, once you have applied a sanding filler (perhaps inside also) no retrospective 'edge glueing' will be required anymore. The sanding filler will probably turn your hull into a quite solid shell.

Thanks to all for the replies!

Your planking looks pretty neat, especially for a beginner (better than mine was, certainly). Should look great when she’s sanded and painted.

I think that's a preference, not a rule. All my models are planked using CA.  One trick I use is to put a little CA in a gap then quickly sand it and the area around it, just a little bit.  The result is almost transparent, not museum perfect, but it works - certainly on an area be painted.
