Mr. Darby questions
I need some help with my Mr. Darby kit. I am trying to install a bow thruster but somewhere along the way one of my measurements was off. I now have two holes aout 1/2" off center. From now on I am going to measure 4 times and cut once!
How would I go about trying to fill in one hole so I can try again? I am assuming that I patch the inside of the hull with fiberglass and fill the outside with body putty. Or would I be better off ordering a new hull from Harbor Models.
Any help would be appreciated.
Thank you.

RE: Mr. Darby questions
Chris,
I think you have a few choices. First, leave the holes off center, it really isn't going to make that much difference. (Except to to you , naturally, since you know the @#$ things aren't right.) Your method is certainly one alternative (did you happen to cut those holes and gave the pieces laying around?), and laying up some fiberglass to plug the holes is another. I'm afraid that the only way I would order another hull is if absolutely nothing else worked after repeated attempts. (That has a lot to do with me being cheap.) I'm also assuming that you have a fiberglass hull. If so, the 'new' one may not be fiberglass. Whatever you decide to use for the 'patching', finishing the patch on the outside is going to determin just how evident the patch is. A good job of finishing would be very nice. Good luck.

Use some course 60-80 grit sand paper, and rough up the area around the hole on
the inside of the hull. On the out side of the hull, tape over the offending hole.
Then, working the inside, brush some fiberglass resin over the area, and press
some fiberglass matte into the resin. Overlap the the fiberglass matte at least
1 to 1-1/2 inches around the hole, and work the matte into the edges of the
hole using your brush. Thoroughly soak the fiberglass with resin as you
squeege the air bubbles out from under the fiberglass, and as much resin out
as possible. Once that is cured, you can put a few more coats of resin over the
inside patch, and bondo and finish the outside as desired.
