Boatbuilder’s Notes


Make a natural mallet


BY ROBIN GATES

Boatbuilders have a long tradition of making their own tools, and with the majority of
new tools now travelling 11,000 miles by sea from point of manufacture to a UK boat
shed, this frugal approach has renewed significance.
A simple tool to make is a wooden mallet, used everywhere from decorative wood
carving to bashing out the waste of a mortice. You can make an effective one-piece
mallet from an acutely angled branch, with head and handle at 45 degrees; similar
branches were used by Bronze Age boatbuilders to make handles for their adzes.
This oak mallet measures 12in (30cm) overall, and 4^3 / 4 in (12cm) from the top to the
striking face, which is 2in (5cm) diameter.
At 14oz (400g) the weight is typical of a carving mallet. To ease clamping, keep the
piece long for as long as possible.
If you saw to final length too soon, the clamping set-up may obstruct the tools. Finish
with linseed oil to resist moisture and the mallet is ready for its first strike.
Compared with a turned mallet with head and handle in line, the acute configuration
seems to position the mallet hand at a more natural angle when striking a carving tool,
and it also strikes with tough end grain rather than the weaker long grain.

Cutting gauge for small rebates
Small, precisely right-angled rebates – or rabbets – can be cut with a cutting gauge. The cutting gauge differs from the marking gauge in
having a knife-edged blade instead of a pin, and is normally used for cutting veneer or thin strips for inlay.
Run the gauge down the edge of the board repeatedly until the cut is down to the intended depth, then turn the board through 90
degrees and run the gauge along the face until the two cuts meet. In this instance I have cut a^3 / 32 in (2.4mm) square rebate in mahogany.
The job would have been no easier or quicker with a rebate plane, and needlessly complicated using machinery. As a bonus, the cutting
gauge removes the waste as a neat strip of timber – not shavings – which may be useful elsewhere.
