Does this look right??? Fs14ls

Post by Ncsharker » Thu Mar 07, 2019 3:46 pm

Hey guys.
Before I go cutting away at expensive plywood.
Does this bend look right?
Everything goes smoothly and looks like the plans till I get to this point.
It just makes a wonky curve in the bow.

I checked all the measurements over and over again.

Just want to ask before I chop I’m a bunch of money.

Thanx guys

It does not look right. It looks like reverse curvature, I almost never use that and certainly not on the FS14.
Which part is that? Which curve, which drawing?

It’s the tip of the bottom bow. I took all measurements from the baseline. Iv checked them all a few times.

Actually hears another question for ya.

Let’s say there’s two measurements. Allllll the measurements are taken from the baseline correct?
Or do I make the first measurement from the baseline and the second measurement from the first mark?

Cool man. I really appreciate it.
I’d hate to waste time and money.

I see it. In this case, for this plan, the dimensions are additive. This means that you measure the first dimension from the baseline and the second dimension from the end of the first: you add them up.
Let's take for example the second line from the tip of the bow for the bottom panel.
It shows two dimensions: 1-1/2 and 9-1/2.
You must mark the first point at 1-1/2" from the baseline and then mark the 2nd point at 9-1/2 from the first one.
In other words, the second point is at 1-1/2 + 9-1/2 = 11' from the baseline.
All dimensions are shown that way, it is consistent.

The drawings do not say "from the BL" but the notes say so.
I wrote the notes and my drafter (which was my son James) finished the drawings.
He is a civil engineering student and certified in Autocad. What he did is correct but does not match my other drawings or the text in the notes.
I am sorry for the conflict between the notes and the drawings. I will change the dimensions type on that drawing.
I am glad you caught it: fortunately, it is clearly wrong, that line is not fair.


For future FS14LS builders: I am changing the dimensions right now, they will all be taken from the BL (BaseLine).

I just gotta say, Mertens, you are a super, super guy.

How many boat designers would see a question from a builder and respond they can't respond the evening and then respond before 10 the next morning and, and erase ego in the matter and understand in detail how the clerical error occurred.

Hope I don't sound patronizing; more in awe.

Thank you so much for taking the time to check it out.
I’m glad I said something.
Your a good guy.

Thanks again.

He's like that. 20+ years ago I was trying to finish a boat, not even one of his designs (some awful Stevenson Projects thing), and he patiently and thoroughly responded to my questions posted on the Usenet group rec.boats.building (if anybody else remembers that). He helped me a lot and told me pretty much everything I needed to know to start working with epoxy.
