scribing planking onto GRP hulls
« on: January 14, 2009, 12:10:19 PM »

Hello all, Has anyone on the forum any experience of scribing planking onto GRP hulls? I am building a Thames Sailing Barge using a GRP hull which although excellent in all other respects, is rather smooth and featureless and willl not give the appearance of looking like a planked hull. I wondered if it would be possible/feasible to scribe lines into the plastic to give some appearance of real planking even after painting and if any member has any ideas/advice on the subject, i.e, what type of tool would be most suitable?

Personally, I would plank on top of the plastic with 1mm thick timbers.

I have seen this done on a Robbe Comtesse. It looked good.

Ray,

You could "plank" it with masking tape planks, as long as they are really well sealed down with paint or varnish

If you just want to give the impression of planking without actually doing it then you could use thin Trimline. The adhesive is waterproof, will accommodate a bit of repositioning and it will take paint. Use masking tape to get the line right first and then apply the Trimline up agaisnt it.

Alternatively, use thin strips of masking tape along the proposed 'caulk' lines and then spray with 2 or 3 coats of spray filler. Remove tape and you'll have the plank effect.
I've only myself for plating but it works quite well.
