Anchor roller

From the start of the boat build, I had intended on handling the anchor with a vertical windlass. Specifically, chain on one side of the windlass, and rope on the other side. For that purpose, I fabricated two anchor rollers welded to my pulpit. After that fact, I came across a good deal on a commercial deck winch which caused me a basic change in how the anchors would be retrieved. I want to center the winch on the pulpit which meant the off centered rollers for the windlass possibly could be less than ideal for how the winch was going to work.

Because I had enough room between the two existing anchor rollers, I decide to cut in a third anchor roller more in line with the position of the new anchor winch. My reasons for centering the anchor roller was to allow the rode ( either rope or galvanized cable) to be square with the winch drum. I'm not familiar with how a winch will work, but it seemed to me that having the rode square with the drum was a good thing. I also did not want to scrap the windlass purpose rollers I had fabricated in case I wanted to go back to the hydraulic windlass set up. The new center anchor roller is more self launching than the first two I fabricated so that is one plus I got out of this little bit of re work I just finished.

I used 1/4" 316 SS plate to fabricate the new roller frame. The frame is pretty robust as it is not a stand alone deal, rather it is welded in to the pulpit so it's supported and reinforced by the pulpit. I added some 1/2" round stock to the area where the anchor flukes will jamb against the roller frame. The actual roller is a composite material turning on a 1/2" SS pin, and is tucked up out of harms way in the frame. I plan on snubbing off the anchor to bits, so these rollers, while fairly stout, will not be taking the loads of anchoring.

I had a large Danforth type anchor in the shop, and that is actually going to be one of my back up anchors. I used the Danforth for a test run on how the geometry of the rollers worked, and I was pleased on how the anchor landed in the roller frame. I will need to add some SS round stock to the under side of the two side roller frames as the center anchor is going to beat these up as it is locked home. It's hard to tell scale from these pictures, but that Danforth is a pretty large anchor. I'd guess the weight of the anchor at 60 lbs with the overall length of the being more than 3'. My buddy Andy Moran gave me the anchor as a boat warming present.

I've had good luck using Danforths to anchor in the river, and I intend on having two aboard. I think my primary anchor is going to be a Manson, and that will reside in the center roller. The large Danforth will reside in the starboard roller, and the port roller will be empty. I will also have an aft anchor which will be another Danforth.

I getting a little tired of re work, but I do think I'm at the end of having to fix changes of design. Re doing this part of the pulpit was not a huge job, but it was a pain. All the metal work is completed on the fore deck, and I can now proceed with getting that area prepped for paint. I have to do some body work on some seams, and a little bit of fairing, but not a huge amount of work. I have decide to paint my 1 1/2" SS rails I welded to the bulwark cap vs polishing them, so that will require a little bit of sand blasting. Polishing the SS pipe rails would probably work for life on the Ohio River, but since I intend on ocean cruising, I fear my polishing skills will leave my rails rusting in the salt water environment.

Paint issue resolved

The biggest issue my last post dealt with was the paint catastrophe I had going on. I'm glad to report that I've figured out the problem, and I can move forward with getting items checked off of the list.

The paint problem I was having is resolved, and I'm happy to report that it was all operator error. The problem I was having with my white paint was that the paint was not atomizing correctly. In a nut shell, the paint particles were too large when they were sprayed on to the metal giving the finish a texture. The problems I was having were a direct result of the following: I was using the wrong reducer. I should have been using MEK, and I was using lacquer thinner. The MEK evaporates more quickly than the lacquer thinner so I can build the film more evenly. My air hose to my paint pot had too small of an ID, so I increased the hose form 1/4" to 1/2" . The friction loss of air in the smaller ID hose caused me to loose volume and pressure in the pot and effected atomization. The hose ID had never been an issue with all the other paints I've applied, but this particular species of white was just a little different animal. The shop temperature was just a little too cold, and required more attention to how I was reducing the paint, and what I was reducing with.

So, I'm going with a dark green on the hull, and an off white on the super structure and decks. The green looks darker in these pictures, and the white looks whiter in these pictures.

Like I said in my last post, this paint is shiny, very tough, and is able to be polished and buffed if I ever have to make repairs on it.

Now that the paint issue is no longer an issue I can move forward. I want to finish the fore deck and get that final painted. To finish the fore deck I need to mount the deck winch and fabricate the dorade box's for the guest/kids cabin. Mounting the deck winch is more of a project than I had figured since I might have to re configure the anchor rollers. I'll have more on that job later as I get some things figured out.

In case no one has noticed, I added a music player to my hipster blog gadgets. A fellow builder I'm friends with has a blog where you can check out his fine work @

The song, "Home At Last" on this playlist, is a more modern interpretation of Brian's boats name, but you'll have to visit his blog to know what I mean. I"m now looking for a song geared towards Hawaiian ducks that are prone to wandering for another builder I follow.

Of course a song for Shannon is on board for all to guess, and one she is sure of.

Turn up the volume on your computer to follow along.
