Planning to build a one meter yacht.
Anyone have a good source for pins for holding cedar strip in place while glue sets. Strip is only 3mm thick by 12mm wide
Balsa T pins are too weak.
Pins are removed after building.
Scared the wood will split if pins are too big.

I and some fellow boat builders make dowels out of bamboo or tooth picks. We pull them through a jewellers draw plate to 1mm diameter. We drill 1mm holes through our planks into the frames and use pva glue. The width of your planks you could use tooth picks as they are and even two in each frame. When going around curves angle the dowels so they hold your plank against the frame saves using a lot of clamps. When dry sand off flush.

Bob......these little nylon clamps with the swivel foot are ideal for plank on frame construction :-))....
The embedded stainless self tapper is approx. M1.25 diameter ........PVA, polyurethane nor superglue adheres to the nylon material......Derek

I always use masking tape when planking.
Works for me.

Hi,
On the Edwardian Steam Launch build, for the first planks at the gunwhale and keel, I drilled small holes in the cedar and used copper coated hardboard pins and brass screws (to avoid rust stains) to attach the planks to the mold boards. For subsequent planks I used wooden clamps to align with the mold boards (use wax to prevent sticking) and sprung clamps between. At the ends of the plank and on tight bends I pre-drilled and brass screwed. To make long lengths of cedar plank, I made a scarfing jig to accurately cut the joints
The cedar was veneered with 0.6mm mahogany, which was initially fitted with masking tape and finally glued and stapled (1800 staples!). the small staple holes disappeared when varnished.
See the Edwardian Steam Launch build for more details.

Thanks to all for the helpful replies. I went with ordinary sewing pins. Used the female battery terminal from a lipo to push them in. Worked very well. Planking now complete and just have to figure out alternative release agent for making carbon fiber fin over glass.
