Thank you, Luiz, and welcome aboard.
The Schooner Bluenose 1921, POF Yuanqing Models 1:72 [COMPLETED BUILD]
I don’t usually use the long reach plastic clamps, but they have them for sale at grainger and other places.
I used the full scale pages to do the frame halves first, then I used a board the same size as the keel to align the halves and clamped them together. Then you don’t need long reach clamps.

I see, makes perfect sense, thanks Dean. I have noticed squaring of the glue joints is required otherwise you get an open "V" groove joint.I don’t usually use the long reach plastic clamps, but they have them for sale at grainger and other places.

Yes, this was discussed before, the lazer beam creates an angled surface, not completely square. Just don't be overzealous and remove enough material to change the shape of the frame!
That is why I used the patterns to keep everything aligned well, and then sanded while the glue was a little wet to fill any gap.
Good afternoon, all.
Here are some additional photos and what I have learned so far. I was gluing up the ribs all at one time which was making me look for some long reach clamps to hold the multiple pieces at bay. Thanks to @Dean62 he showed me a better way to construct without the hassle of multi clamps (see above post #43 for explanation). One of those simple solutions I am grateful for.
Above, you can see I started on the keel in between drying time for the ribs. The 1st through 8th rib is just dry fit at this time and are only 80% sanded. I will need to add tree nails to them before sanding out the faces. You will see a small amount of char on the exterior edges all the way up to the final fairing step.
Above I've indicated where the fairing direction will change going towards the stern. This just keeps it straight in my mind.
And last for now I had a little problem with join up at the stern keel, see the filler, it should be mostly covered when finished and hopefully will not create problems down the road.
So, thanks for checking in and Happy Modeling.

Hey Daniel, glad the tip is helping. One other thing, be sure you use a board top and bottom, to ensure the best alignment...sorry I didn't make that clear in my first post. See highlighted below in yellow...
On the keel stern area, that is odd! It is almost like the part was not correct?
The most important thing is the frame spacing... one to another! It appears you had to space the upper part of the stern keel back towards the stern in an effort to make things fit better. however the frame space might be effected as highlighted below...
Once the upper most part of the keel is attached, it will be located from the last frame opening. All this determines the frame locations at the stern. The end of the keel where you used a shim, is only the location of the rudder, which can be adjusted easily. Whatever you do, don't change the location of any frames from one another. The keelson will tell you if you are okay on the keel.
Hope that makes sense to you?

You should be able to lay this (stem/keel/stern) on the full-size plan and see how things are matching up. I'm with Dean - there is little room for latitude here.Hey Daniel, glad the tip is helping.

Yes, perfect sense, in the back of my mind I was going to hold the correct frame positions regardless. I did make a piece to hold the keel slots even.
Here is the tail, which I located from the last frame...
As you can see below, the half frames are located on the tail section of the stern...

If you move that one piece, every frame located on it will be off by that same amount. But don't panic, it will lengthen the ship by that amount (which is very small) and the waterway boards and deck will have to be adjusted potentially, But that is not that bad. You will find anything that is off, will effect something else that comes after it. So this frame skeleton you are creating, is the backbone or foundation of the whole ship. Not trying to be rhetorical, just reminding you! But once again, adjustments can be made. So be slow and methodical to ensure this is as true as you can possibly manage, as it will pay off in dividends later in the build.
When I glued my frames in the keel, I used spacer boards to ensure the frames couldn't twist and cause issues at the deck beam level. Any angle out of square effects frame spacing at the top.

Yup your right Dean, frame #40 thru #49 would be shifted 1mm towards the stern therefore I will file 1mm of those notches 1mm to the bow end and make sure the fit is to the bow end and problem should be solved.Hey Daniel, glad the tip is helping.

I wished I had a longitude 1:1 cross section but I don't so I used the jig itself by laying the keel sideways on it. It does bear out the error, but I believe I can overcome this, thank goodness the offset was only a millimeter. And yes, a slight error will propagate itself in these situations.
Hmm. Which still leaves the height of the frames off. I'm not sure how precise things need to be on this BN kit and I would hate for you to have problems later that could be avoided. But since I'm working on my first POF build I'll shut up now.
I spent many years in the field laying out bridge bents and abutments always striving to have the finish product come out within a quarter inch. The superintendents would get irritated and say were not building a piano here Thomason so hurry up. It would seem you and I might could build a piano when all this is done. I know Dean could now if he wantedHmm. Which still leaves the height of the frames off.

Ha! Too late, I already saw it. The do over or in this case fortunately is just a slight modification. The challenge continues Johan.

Be sure to use a 1mm shim on the stern side of the slot. And keep those edges parallel and vertical with respect to the deck, not the bottom of the keel.
But if you use the jig, and spacers in between the frames at the deck beam height, the frames should be parallel to one another and equally spaced.
In addition, after cutting your frame notches 1mm towards the bow, I would place a frame in there and glue a shim in place on the stern side, so that it’s snug. Then you can trim and or sand the shim once dried, and the frame is removed. Just a thought.
If he maintains the bottom horizontal edge of the frame slot, moving the face towards the bow will not change the frame height. But this only because the bottom of the piece that was shifted is horizontal.Hmm. Which still leaves the height of the frames off.
