It is certainly more than adequate a fastening method for light
And it can be quite easily done by one person.
These nails are particularly useful for fastening the laps between lapstrake frames.
They should be sharp enough to penetrate the wood when clenched over.
But not so fine as to allow the point to curl when being driven.
In the absence of proper clench nails copper boat nails can be used.
Clip the boat nail off at an angle sloping away from the direction you are going to clench it.
Then tap it on the end to produce a barb.
buy on-line The only tools required for clenching are
A light hammer to drive and clench the nails.
A drill fitted with a slightly undersized bit for boring the pilot holes.
/’bucking’ iron, a large hammer head will do, or any rounded lump
First clamp frames/stock in place.
Next drill the pilot hole for the nail, this will reduce the hammering required and avoid the danger of splitting the wood. Light construction doesn’t like too much hammering.
Either use the ‘bucking iron’ to curl the nail back on itself as soon as it emerges from the wood.
Or drive it right through then place the ‘bucking iron’ on the head and use the hammer to curl the nail.
When the point enters the wood hammer it flush.
It is best if the nail is clenched slightly across the line of the grain rather than along it.
A few light taps with the hammer will draw the frame onto the plank.
Although it will be much faster to work with two people, one nailing and one wielding the ‘bucking iron’, this is a job that can easily be done by one person working alone.
