Tiny Titan Build - Bow Complications

Post by largej » Thu Feb 13, 2014 10:21 am

Hi folks,
Working on my 1st build - Tiny Titan. I have run into a situation that is either me just missing something completely or something is off in the plans - I am sure it is not the latter. I will try and explain below:
I have the bow completed and it has been done as per the plans. When I try an assemble it is a half inch short where it butts to the #1 frame when I align the notch in the #2 frame. The distance from the notch on the bow to end is 24 inches. The distance beteen the #1 frame and the #2 frame is 24 inches. If the bow end butts to the plywood on the frame and the notch goes to the front of the #2 frame shouldn't the distance from the notch to the end be 24 -1/2? Maybe I have the frames racked? I checked they are perpendicular to the bottom planking.

I really like the way the bow turned out. My 1st at laminating and preparing a rather large part. I could deepen the notch on the bow where it meets the #2 frame 1/2 inch. keeping it parallel. This should only shorten subsequent parts/planking correct?

Any information you have would be appreciated as I have found this forum to be a really great resource for a novice builder!
Thanks - JIm

Jim; Pictures will help you get a solution/response as sometimes it's had to visualize the problem

There are quite a few of those that have been built. I'm sure somebody who has built one will chime in. There are pictures in the archives of some of the build stages. They might shed some light on your problem. Here is a link to one build.

Jim: I've been looking at this pic and still can't get it figured out.

Doug,
If I can figure out how to attach a pictures I will -- Ok here we go:
Here is the basic problem - Bow in place at front (stem?)and 2 Frame but short at 1 Frame by 1/2 inch

This shows 24 inches between frames
IMG_1116.JPG
This is the end to notch on the Bow

Anything you can suggest? I knoe these are not the best but might give you more of an idea.
Like I said, the bow piece was cut to spec.
Thanks for looking.
Jim

Jim; I may be wrong, but I think the best solution to the problem,(not really that difficult actually ) would be to lengthen the bow piece ( the "U"shaped lamination) by the amount required to fit in to the frame notch.( 1/2" ?)
The best way to accomplish this is to cut it back 6" or so and scarf a piece on, using a jig and a router to accomplish this, When it's epoxied in place, it will be fine.
Somewhere in my posts on the Gentry build there is a picture of the jig I used.

Possibly frame (2) was put on the wrong side of the line considering your error and the frame are both 1/2". I agree with slug, ... lengthen the bow pieces. Did any of your measurements change between frame (2) and the transom that you'd be willing to admit to, ... ? :shock: :mrgreen:
