Fairing a Hahn POF hull

[butch]

Does anyone have advise on fairing a plank on frame Hahn style hull? Any special tools? What are the common

mistakes? Do i install the cant frames before fairing the common frames? How do you protect the keel and the

stem? Any ideas concerning fairing the inside of the hull? Power tools?

Thank you,

Pete

I am watching this Post to see what all the different methods are that people use to fair the inside of a POF.

I just used a sanding block on my Fair American.

Pete,

There's lots of ways of fairing just as there are lots of builders. 

 

Many of us make our own sanding tools.  I use a combination of round tubes, stiff plastic sheeting, even wood strips and blocks, all with sandpaper rubber cemented to them. 

 

It its easier to fair the inside before installing the fore and aft cant frames. 

 

I'd suggest crusing the various scratch logs, and not necessarily just the Hahn logs, as there's an abundance of good info on this.

Mark is correct, there are as many ways as there are builders, and if the method works it is the right way to go.  I usually build the cant frames first, thus fair them first.  I usually do some pretty aggressive fairing before setting them in place, then after every two or three frames are set, more fairing and finally finisht the fairing after all the cants are in place.  The inboard surface for the square frames are easy by comparison,

 

I use a Dremel rough sanding in tight spots and a mouse sander where there is room.  Sanding sticks with various shapes and grits work well for the final fairing.

Well has others have said, all kinds of things can be used for faring one's hull. I have used a drill and dremel with sand paper type flapper brushes, flat and curve pieces of wood with sand paper cement to it, metal scrapers and curved rasps. One can also use a mouse type sander that comes to a point in getting in to tight places. One item that seem to have help me a lot with fairing the inside of the bow and stern of Alfred's frames was broken glass used like a scraper. I know but it worked and didn't get cut once.  Take a piece of picture glass, cover it with a towel and with a hammer tap the glass. You will be surprised at how many different shapes you will get for fairing the inside of the frames, and once it becomes dull, just get another piece.     :piratetongueor4:

Thanks for the shattered glass tip, Gary.  I never would have thought of that!

 

(Do not attempt this at home.  Stunt was performed by an advanced modeler in a closed workshop.)

 

 

As you can infer from the previous posts, this is a part of the build that many have come up against without a pre-ordained answer, and they've discovered what works for them.  There's probably no single best solution.

 

I primarily used a "sanding sled", a shaped piece of wood with sandpaper glued to it.
