Clay Bar
SBMClay bars are available at auto parts stores. They come in different grades (this blue bar is a #1/Fine) and sizes (at 100 grams, this is one of the smallest). It cost around $12 and comes in a resealable pouch to keep it from accumulating grit.
Tim Murfitt of Norwich, U.K., bought a classic car a few years ago, and while researching how to improve the paint work came across the clay bars car detailers use. Later, when he did the paint work and varnish on his Savo 650 in the same dusty shop he built the boat in, he was disappointed with the flaws to the finish and thought he would give the clay bar a go. It only took him 30 minutes to do the whole boat inside and out, and he was amazed at the transformation. It left both the paint and varnish feeling silky smooth.

Editor Chris Cunningham bought a bar of detailing clay and unexpectedly got a chance to try it out sooner than he expected. He’d made a new bathroom cabinet with nice Douglas-fir, varnished it, and accidentally dropped the mirror frame while it was drying. It picked up a lot of dust so he let it dry a couple of days and just took the clay bar to it. A quick rub with the bar and some soapy water took off the imperfections and didn’t dull the shine.
Varnishing oars
Ben FullerA pair of sawhorses make contact with only the handles and the leathers, leaving the rest of the oars free for varnishing.
If you find oars unruly subjects for varnishing, you can get them to behave themselves, as Ben Fuller of Cushing, Maine, does by cantilevering them on a pair of sawhorses. With the leathers resting on one, and the handles tucked under the other—weighted if necessary—nothing is in contact with the areas you’ll varnish. Spring clamps either side of the leathers keep the looms from rolling while you’re varnishing one side and allow you to turn the oar over to brush the other.
Rope cinches
Christopher CunninghamWith a rope cinch, you can wrap the line around something like a sleeping bag, tie the rolling hitch, and then put the squeeze on. That’s easier than compressing something and trying to tie a knot at the same time. And unlike a bungee cord, the rope cinch has an unlimited range of adjustment.
Our editor occasionally uses a piece of rope as a belt, but it’s hard to get and keep it sufficiently tight while he ties a reef knot or a shoelace bow. A rolling hitch (Ashley Book of Knots, #1734, page 298) makes a belt that he can tie, cinch up, and have it stay tight. With repeated use the sliding knot will get tighter, so it’s best to start the next day retying the belt. Smaller versions of the rolling-hitch belt can take the place of straps and buckles for cinching sleeping bags or bundling spars and sails.
Christopher CunninghamStart by taking two full turns around the standing part of the line. The standing part’s end is at the bottom; the cinch’s loop side is at the top.

Slotted Foredeck
Patrick MacQueenThe slotted foredeck makes it easy to step the mast and raise it. For trailering, the spars all fit inside the boat by tucking one end under the aft deck and slipping the other down through the slot.
Patrick MacQueen of Hancock, New Hampshire, set out to build a Herreshoff Coquina and decided that wider decks for sitting and hiking out while sailing would be an advantage. The deck required another modification. Ordinarily the mainmast partner is set right into the breasthook and the narrow decks taper up to its corners. It didn’t seem to Patrick that the taper would be an elegant resolution for the wider side decks.
Patrick MacQueenPatrick MacQueen’s slotted foredeck and modification of the Herreshoff arrangement for the decks maintained the boat’s original functions and gave it a different but fitting appearance.
A foredeck would look better, but would make stepping the mainmast far more difficult. Patrick struck upon making a narrow slot running up to the partner at the rear of the breasthook; it would allow for easy stepping and unstepping. The Coquina’s decks had to look pretty, of course, so he glued 1/8”-thick strips of mahogany and ash on the 3/16” marine ply decks and finished them off with ash coamings.
Farrier’s Rasp
The farrier’s rasp that Tom DeVries, of New Braintree, Massachusetts, bought at an antique shop for $3 was designed for trimming and shaping horse hooves, but it also works beautifully for tapering ash stems, bringing oak bungs down flush, and rounding spruce oar handles. It’s quick, quiet, and relatively safe.
Tom DevriesOne side of the farrier rasp is a double-cut file for finer work.
One face has rasp teeth and the other is a double-cut file. The rasp side cuts even hardwood quickly down to size, and with a flip he can use the file face to finish smoothly. Tom has used his 17” farrier’s rasp to shape beveled stems on the double-enders he has built.
Tom DeVriesWhile the file side is working a hardwood stem, the teeth of the rasp side are visible.
The long, keen, shearing cut of this big file makes fairing bungs flush faster, with little of the risk of tearout created by chiseling bungs. He tapes the end of the rasp to prevent inadvertent scratches as the bung comes flush.
Tom DeVriesTom took a grinder to this edge to remove the teeth, making a safe edge that could ride on an adjoining surface, like the shoulder of he loom, without cutting into it.
Both edges of a farrier’s rasp have teeth; Tom used a grinder to make a “safe edge” he can use to work tight to an adjacent surface. It comes in handy for working and oar’s grip up to the shoulder of the loom. Farrier’s rasps are readily available from many online sources.

Having grown up with both horses and wooden boats, farrier’s rasps have always had a place on my bench. To that end, farrier’s rasps come in many different grades: they’re all quite aggressive, but a “Black Master,” for instance, will give a smoother finish cut than a “Red Tang,” which is in turn better for fast stock removal (I use both). Good feed stores and farrier’s supply stores will have a selection of brands and models to choose from. And don’t buy the cheap ones; like any other tool, you generally get what you pay for.
Thanks, clay bar and farrier’s rasp. I will try both!
I learned a version of the rolling hitch in the Boy Scouts. It was called the Taut-Line hitch, and we used it to tighten the guy lines on tents, etc. Looks like pretty much the same knot.
Yes, the Taut-line hitch is the same thing. I should have mentioned that as it is pretty well known, but I didn’t find it by that name in Ashley’s. I had thought the taut-line hitch worked because the line looped through the eye of a tent stake, and the tension on the standing part of the line helped the knot function, but the rolling hitch creates friction and will hold itself in place even if the standing part of the line is slack.
We have used farrier rasps for years to clean up gobs of epoxy. They save a lot of 36-grit paper.
The sliding hitch reminds reminds me of the mountaineer’s Prusik knot (a loop of line used to ascend a rope), which I have used while boating.
The Prusik knot is another kind of friction hitch. It is usually tied with a closed loop of cord wrapped around a climbing rope and has two or even three turns on both the high side and the low side.
