The Treasure Chest is a place to put those cool sailing, cruising, motoring, boatbuilding or boating tips you have. Send us your ideas... We just need a photo and a short description.

This time we have...

Gluing

Ran across this article (PDF) - one of the best discussions of gluing wood that I have run across. Have to read through a lot of gobdleygook to find the nuts of wisdom, but it was worth it for me and maybe you can tuck it in DW somewhere.

SD-082010 Nylon Fairlead

In deciding to use these for the attachments, I did a bit of testing to see if they were strong enough for the task. The testing was done by screwing one of the fairleads to the ceiling of my shop, looping a length of 1/4" line through it and standing in the loop with my full weight (180 lbs.) The test was successful and and the trampolines now allow me to walk on them very easily.

To The Freezer

One of the reasons I hate to use epoxy is that I mix too much or too little. I just discovered a little trick that is very convenient when I mix too much. Stick it in the freezer asap.... before it starts to kick. If there is a small amount, it will cool off very quickly and become so hard it is brittle. It is then impossible to get out.... but it is brittle, so you just whack the bottom and it will break into pieces like glass. Pick out the piece the right size and put the rest back in the freezer. The piece will quickly melt with the heat of you gloved fingers. Apply to whatever and it will kick as normal. It has lasted two weeks in the freezer and that would indicate to me that it will last mixed a long time. The hardening must stop at freezer temps. It hardens just as normal without any discernible difference, the best I can tell. Does anyone see a negative?

Leeboard Traveling Support

I posted some new pics in the Jim Michalak forum showing how I tackled the problem of supporting the raised leeboard on my Ladybug when trailering. This morning it occurred to me that it might be more helpful in The Treasure Chest so here is an edited version.

Looking closely at the photos, you'll see that I have an uphaul lanyard running from the rear of the board up through the aft end of the upper leeboard guard & through a cam cleat. To take much of the load off this cleat, I cut a 2"-3" dia. circular washer from an old 3/8" thick nylon kitchen cutting board, drilled a 6mm hole in the centre & threaded it onto the 6mm shock cord lanyard attached to the aft end of the top of the leeboard & cleated off (under slight tension) in a jam cleat on the gunwale well aft of the leeboard. This shock cord acts to hold the board down when under way, although it does not seem to want ride up if the lanyard is left uncleated.

With the leeboard all the way up & the uphaul lanyard cleated off in the cam cleat, I slide the nylon washer all the way forward on the shock cord lanyard & feed it edge-on down through the gap between leeboard & guard, that opens when I lift the board a bit more, until the washer is sitting flat on the back of the board. Let the board drop back down & the washer takes the weight as the board presses it up against the underside of the guard. It is positively located by the lanyard & can not fall out. The board is now secured by the washer & the cleated uphaul lanyard.

This all sounds a bit long-winded, but a close look at the photos will tell the story. Very simple, quick & secure.

Lots of pics from different angles.



I hope this helps someone.

Balance Beam and Gloves

Microsoft excel can convert fractions to decimals and back again. Simply enter your dimension in a cell, then right click on the cell, select "format cells". The format cells window will pop open. Select the "number" tab at the top. To change from a decimal to a fraction, select "fraction" from the list at left, then the desired output on the right. Click "OK" and you're done. To go from fractions to decimal, choose "number" from the list at the left, then the desired number of decimal places on the right.

Of course, that doesn't deal with feet-inches-eights layout common in boat building, but one could input feet in one column (say cell A1), inches in the next (say cell A2), and eigths in a third (say cell A3) (input as a whole number, just like on the plans). Then, cell A4 could contain the formula =((A1*12)+B1+(C1/8))*25.4 to convert it to mm.

Boat Drain Wick

Since finishing my Ladybug, I have had to leave my 11' bateau.com GV11 dinghy right way up under a semi-porous cover, out in the open. This cover lets a tiny amount of water through but blocks out all the leaves & stuff that blow around & end up inside & allows some airflow in which effectively keeps mould growth at bay & the inside fairly clean.

The bung is left out of the drain of course to let water out, but as most drains are set a tad above the bottom line of the hull floor, there is always 1/2 cup or so left to get mouldy & stain the paint.

The answer is simply to coil a short length of cord up against the drain hole & let a few inches hang down towards the ground. I have just used 4mm vb cord but any cord will do. This wicks up the water & drains it overboard.

This system is good too for areas like saucers under pot plants that tend to stay full of water & cause root rot....not a very nautical application I suppose, but people with live-aboard narrow canal boats & houseboats may find this handy as they often grow all manner of plants on board.

My pics also show that I have a bit of o/b oil & grot that I must clean up.

DIY Roller Furler

I just built a really nice roller furler for $40 that might be of interest.

In issue #58 of Small Craft Advisor magazine, Kirk Gresham wrote an excellent article on how he designed and built two roller furlers for his 17' cutter Eider for a mere $40 each using bits of scrap and a few bits and pieces of hardware from a local hardware store.

Months later I headed for the local Home Depot to obtain the rest of the parts. While browsing through the plumbing department I came across some parts that looked like they would make for a very nice looking unit. An ABS end-cap for a 4" pipe looked like it might be more attractive than the 1" aluminum strap and perhaps even contain the furling line better too. I also found an ABS pipe coupling that was wide enough to cover the two legs of the U-Bolt, possibly making it wind more smoothly as well.

So, here I present my slightly modified version of Kirk's $40 roller furler.

Cheers!

For you tool freaks...

When cutting FG cloth, with the weave, I get the end of a thread and pull it all the way out....along the line I want to cut. That allows me to see a line and cut the cloth straight without crossing over into other threads, wasting cloth and all the raveling that causes. Much neater.
