Questions with my first boat - D5

Post by Ishpatucky » Sun Sep 10, 2017 8:29 am

I have a question on one of the steps on building the D5, it says to measure the diagonals. Does that mean I should measure from the upper bow transom corners diagonally across to the rear transom and compare? Sorry, I haven't actually bought or read a book just have been reading a lot online and I cant seem to find where anyone has gone into detail on this step. I assume the above is what I have to do and that if the diagonals are not close I should adjust the "stitches" around until I get close.

Is there a rule of thumb on how close the measurements for the diagonals should be? or should they always be almost exact?

Well . . . if the panels are cut perfectly then you should try to get the diagonals to match perfectly, too. Of course, reality will come along and it won't be perfect, but why plan to make a crooked boat? Most guys are happy if they get within an 1/8" or less.

Hmm I got the boat stitched up and measuring my diagonals from the rear transom to all frame pieces match within 1/8th, but when I measure to the very front at the transom I am off by an inch, I think I screwed something up a the very front...

You're going to want to re-check the dimensions on the bow transom to see that they match the plans, if you haven't already done so. An inch is a bit much although probably not catastrophic; but I'd want to know where the error lies, and it would bug me.

If it doesn't bug you, and the frames all seem to fit then the boat will be ok.

Mine were out by 2cm. I could get them even with pressure, but couldn't maintain while gluing.

I can't tell unless I get the tape out.

Totally up to you to decide if this is ok or not in my opinion.

If I were redoing it, or if this was a planing boat I would do this:

Fix a strong cord from a nail on one corner to a cable tie around a nail on the other. Do the same with the other two corners.
TIghten or loosen the ties until both diagonals are equal in length, and the cords meet in the middle.
Spot glue between stitches.

Very cool idea OneWay! I think that may fit well in the Builder's Tip set of threads.
