Lе Rochefort 1787 by moreplovac - scale 1/36 - port yacht

[Tonphil1960]

I used the Hahn method for frames and have spend many hours on my LeRo and in the end I’m going to scrap the entire project. I made serious mistakes in haste because I didn’t want to cut each frame piece individually. The joints of the frames keel and keelson are very very  critical. I succeeded with my Blandford section by doing the frames piece by piece and the correct way. I didn’t want to spend the time doing it on this model with bad results.  By all means glue up the frames over the template leave them all

larger all around and sand to shape.  I’d hate to see you in the position I am in.

Thanks Tonphil1960, appreciate your comment

I am just experimenting with Hann' method for one or two frames. I already cut all my frame parts, sanded them to correct thickness and spent some number of hours working on them so will continue following Rochefort practicum.

Wanted to see how this will work since people are talking about a lot :-).

Yes understood. I can see doing it but I’d didn’t work out for me. Good luck

Not putting too much hopes into but want to try...

Now it is time to start making some frames, finally... I might jump on another part of a ship while waiting for glue to dry... 

I gave up on glass as a foundation to work on, since the distance between plan and actually frame (sitting on glass) is several millimetres which can cause me mis-positioning of frames, etc so I ended up "stealing" cooking paper (very handy, non sticking paper) and place it on top of copy of a plan, which was cut in strips, having only one row of frames visible. The plan was fixed on piece of bright white wood, from kitchen door I bough in Ikea, as-is. Very handy, perfectly flat with that blue protective paper still on the door finish. 
Door was glued to two scrap pieces of wood, so I can squeeze under it my long jaw clamps. On top of a plan, I fixed parchment paper. Plan is very visible and parchment paper allows you to squeeze frames, with glue without stickiness. I believe it is betted than glass in that area. CA can easily stick to the glass but it will not stick to paper, at least in my experience. For glueing I am using mostly white glue but on some parts CA as well.


Frame 10 with all parts is ready...

I also measured distance between frame sides so will try keeping it as close as possible to measured distances. I measured on two areas:

So.... here we are..

And final glueing and drying...

Another one done, using the same method..



Three done so far; might need to speed up process but missing proper clamps... Yet another time for me, the truth become more truth again: don't buy cheap tools, including clamps...I had 10 on those black clamps (above photo), very affordable price, but when I start using them, only 5 were usable; I was unable to open clamps to use them so they ended up on "I might use this sometime for something else" pile of scrap things.

Happy modelling..

With current frame assembly method, I cannot see the template on one side of frames so I extended a line on plan and also marked the same line on the frame pieces that are finish up at the top. The line is actually inside sanding marking line so I can measure distance as accurate as possible and getting desired results. Trying to achieve the least amount of rebuild as possible...

Also, the line is traced on the timber and half timber to make sure we are on the spot..

I also have another approach of frame assembly and will see how this goes but will stick with what practicum suggested: floor timber and half floor timber glued together on the keel and rest of frame parts added lately.

Frames are keep piling up..

Happy modelling...

Frame build work continues...

Testing frame #16..

It fits perfectly but the middle line on a template does not align with a keel, not to worry, this is additional template (for sanding) I put on but will replace it with correct one. This one does not fit the frames, moved to the right 2mm approximately...


Pile of frames keeps pilling up...

Some parts needed to be redone; some are gone missing somewhere, or stolen by my cat, or will just be located when I start cleaning up my hobby room; anyhow, usage of old parts is there..

Shhh, don't tell anyone, some of frames will be "simulating" edges, like we do for deck planking, simulating planks, out of one long plank... I would call it "using different techniques for frame build"... Did not follow the gran on purpose for those one, just want to see how this works.. if does not work, will re-do correctly..

Happy modelling..

[moreplovac]

OK, parts are cut from the board and ready for raw sanding..



Sanding is done, now correct thickness was achieved buy running each piece thru mini table saw..
There is always a lots of leftovers, that can be reused somewhere on scratch build project..



And saw dust as well.. looks like chocolate..



Parts are ready for assembly..



Happy modelling..

[Tonphil1960]

Good progress. Move slowly and carefully and you'll be fine. Not as easy assembly.

As per practicum, frames from 5 - 24 are built; #7 is in drying process at this moment...

Just curious to put them on... they are not fixed yet to the keel, nor adjusted so some of them are a bit out of line..


Next is a nice amount of sanding... then rest of the frames...

Happy modelling..
