I want to build an anchor platform that bolts to the bow and extends
off about 2 - 3 feet for safely deploying the anchor from. Usually there is a roller installed through or on them. Here is a company that is selling something similar to what I want to build myself: http://www.butlermarine.com/anchor%2...eakpulpit.html They are usually constructed of layed up strips of teak. Thanks! Rob To be more specific, I am looking for the proper technique for laying up strips of teak in a way that will produce the strength required for a pulpit. I have been suggested that it is sufficient to just epoxy and clamp the strips. I have also been told that I should screw and epox the strips together. Additionally, I would like to put a channel in the pulipit for wiring in order to put the nav lights on it. Well, it will not be the first time I sounded dumb, but what exactly do you mean by "pulpit"? Scotty (orbital) wrote in message . com... Hello, I am looking into the option of custom building a teak anchor pulpit for my 28 Cape Dory power boat. I was wondering if anyone could help me with some insight into the proper technique for doing this. Any help would be appreciated! Thanks in advance. Rob |

Mine is made from strips of teak maybe 1" x 2" laminated and screwed
together, with the strips oriented vertically. If you have room, I highly suggest making it big enough to hang two anchors from. "orbital" wrote in message om...

I have a 38 ft sail boat but pay for a 45ft slip because of the bow sprit and outboard rudder.. For me, that is an extra $35/mo. But I don't have any choice since my boat is designed with a bowsprit.. Steve |

Scotty, Thanks!
This is exactly what I was looking for. This sounds relatively straightforward. Even your ascii diagram of the opposing end grains made sense. I assume from this point, I could cut the finished piece as if it was a solid piece of wood to create any curves or shape I want to add to the front of it. Can you elaborate on the idea of pegging? I have an idea what you mean, but am not sure exactly how this works. Do I make pegs from dowel and drill corresponding sized holes into the strips? Is there a technique for making sure they line up on the 2 strips? How many pegs per strip should I use if the pulpit is to be 3 feet long? How deep into the strips should I drill for the pegs? Also, I would like to put a channel down the length of it to accomodate a pair of wires for a nav light. I was thinking I could route a channel on the face of 2 strips before glueing them up. Would this affect the strength greatly? Thanks again for all the info! Good luck with your leaky wall! Rob Ahhh, I get it. Before I built boats, I built butcherblock dining sets, counters, desks, etc, so this is right down my alley. I would start by getting some 4 or 5 quarter (finished) material. Get planks that are a little more than multiples of the thickness you want plus saw curf, plus another 1/8 to leave room for finishing the top and bottom later. For instance if wanted a 5 quarter finished product you would look for boards where the width was a little more than a multiple of 1 1/2 inches. Take your planks and cut out the 1 1/2 inch strips and lay them out with the end grains direction turned opposite each piece so the finished part will not warp in one direction or another like this picture of the end grains of a correctly made butcher block type table |////|\\\\|////| if that makes any sense. Anyway, you may want to peg the parts to keep them from moving in the clamps, these pegs are just for that and not necessarily structure so use them sparingly timewise... When you have all the parts cut and ready, get some epoxy and some cheap (relatively) pony type bar clamps, available at home depot, get enough so you can put a clamp at least every 9" to one foot. Using throw away brushes, slosh the part faces with glue, and knock them together. When you have laid as many as you wish or all, put some wax paper on the edges and some good thick, straight planks on the outsides of the part and clamp it up. If you don't use strong backing planks, use more clamps. Again, you may make the part all at once, or break it up. The epoxy if used properly will hold fine, especially if you peg it. As to the railing, either steel which Glenn can address, or steam bent wood. For a first timer, I might suggest looking at steel as there is some learning curve in steambending wood, and we don't want to learn the hard way with such an application.

Jumping in here ...
If you recall, Scotty was the guy suggesting pegs. He also suggested using epoxy. So, I want to say a couple of things before people get too far off track: - The pegs are for alignment. You only need a couple per side of strip. If the pulpit is long and the strips non-flat, then go with three so you can get better alignment while gluing. Once glued, the pegs don't add much if anything to the structure. - If you're going to seal the pulpit up, and it's not hard if you use an integral anchor roller that takes the anchor abuse instead of the pulpit itself (see any commercial version), then epoxy is fine. If the wood is going to be exposed and stay that way, then I'd consider using a different solution (resorcinol glued teak? through-bolted teak? I don't know ..I'd use epoxy as described).

This is correct and I do suggest a cheap dowling jig from Sears or such, this will allow you to use line things up much easier but like brian said, they are not there for structure. Use them sparingly as I noted in an earlier post, to save time. Scotty |

I was planning on building a slot into the pulpit to accomodate a
roller. I may also mount a stainless plate on the bottom to protect the bottom of the pulpit from the anchor being yanked up into it. What is the issue with using epoxy if I do not seal the entire pulpit? My intention was to most likely not seal it with urethane or epoxy, but to keep it coated with teak oil. Also, I have never heard of resorcinol before now. What is the difference between this and epoxy for this type of use? In terms of using or not using pegs, I guess I was concerned about the pressure and weight of the anchor trying to pull the strips apart vertically. I was thinking that screws or pegs would help keep the pulpit together when these vertical forces are aplied unevenly to particular strips making up the pulpit. Is just the glue up strong enough to keep it all together? Thanks! Rob If you recall, Scotty was the guy suggesting pegs. He also suggested using epoxy.

The issue with epoxy, as with any virtually waterproof coating, is that
moisture tends to migrate through the wood until it reaches the waterproof barrier. This region tends (then) to carry more moisture and becomes a possible rot risk. If you are *not* going to seal it and keep it completely sealed, then I would not use epoxy as your glue. Do a search on the web for resorcinol, sold under the brand name of GluVit (among others), and see what you find. The question I have is whether or not it bonds with teak well. Either way, if not using epoxy, then I would also recommend mounting with hardware, not gluing. You'll want structural support from gunnel to gunnel as a minimum and then through-bolt with 316 stainless or silicon bronze or better. Make it strong enough to stand on. For making a strip-built pulpit without glue, then you'll have to build it up strip by strip using countersunk boat screws. For these 'buried' screws, use silicon bronze or better (see Jamestown Distributors online). Screws should be offset back and forth as you go so they are not in alignment with each other. This will distribute the load better. Left to my own devices, I'd probably shoot resorcinol in there between the layers as I screw them up, letting the screws be your clamp pressure. On the outside 2 strips, countersink deeper then use a plug cutter to make plugs from your teak. You can glue these in to hide the screw tops and then flush-cut with a Japanese pull saw. When the whole stack is done, expect to at least router and sand. May have to do some planing too, so start thicker and wider than your intended final dimension. Use a low-angle block plane and keep it sharp. The silica in teak takes the edge away quicker than with other woods. If you're a clever guy and would like to do a fancy job, you can route with a 45-degree bit on the top corners of each strip of teak to dress it up a bit. I know you can fill these grooves with black polysulfide to emulate a teak deck, but I've never done it and suspect that it may be hard to do it neatly. The grooves alone would look nice (make sure you clean glue out nicely if you are using it.) When the pulpit is all done and right before installing, then you can oil it in the traditional way ...soak it well where it contacts the boat.
