Planking screws (Moved by moderator)

Recommended Posts

Started work on Constructo's 'Emma' a Baltimore Clipper Sidmouth 1815, she's an older model 1:50 Scale, and what may I ask is your current project?


Was a busy builder 20 - 30 years ago.  Spending most of my time building up my tool chest, lost and mislaid most of my kit, but I guess I'm 75% stocked up again.

I have been using commercially made plastic planking screws for years. They work quite well  but after a while the head of the screw starts slipping in the plastic casing. It is not accessible and super-gluing it on the outside is only partly successful.




I thought about investing in the Micromark metal clamps, but they are a bit expensive. I then came up with the following idea and made a set of my own planking screws.


Sneaking into the back yard under the cover of darkness, I pilfered some of the Admiral's plastic pegs from her peg basket.




I dismantled the peg and cut off the ends




I then used some 8mm dowel and some 4G by 20mm wood screws to make the `handle' of the planking screw.

4G by 20mm was the thinnest/longest screws I could find so I had to recess them into the dowel so they were long enough to go through the bottom. I had to grind the screw heads a little so they would fit through the dowel.

I then cut notches, using my hobby knife,  into the `wedge' of peg that I had cut off and drilled a hole as close to the end of the notch as possible (this gave the most leverage when screwing in the planking screw)

The pic above shows a peg end with

and without the slot


I then fitted the dowel `handle' to the peg `wedge' to create the planking screw.




It did not take long to make up a set




They worked quite well, especially on straight runs




I thought I was very clever until the Admiral questioned me about all the half pegs in the rubbish bin! Gulp, I knew I should have buried the evidence!

I bought those Micro Mark clamps too. The problem with them was that the material used is very soft (some lead/tin alloy) , leaving dark marks into the planks. They also bend very easily under pressure.

This is why I made my own clamps of 6 mm brass rod, which was knurled and a 2 mm hole drilled into one end. A 2x16 mm screw was epoxied to the hole. Pressure part was made of 2 mm plywood, and the clamp was ready and didn`t cost anything. No dark marks any more into the planks:
