Re: 17.5' Hourston Glascraft stringers
Hello Caribear and welcome to Iboats
..
Its kinda simple actually
..
Find a spot that you think your going put the pie plate..
Take a hammer and kinda tappy around that area... You should kinda hear a hollow sound here and there and then you might hit some ' Thud ' sounds ( kinda feels/sounds solid ).
So when you Think your kinda 5" away from any hard spots all the way around your tapping..drill a small 3/16-1/4" hole very slowly just until you break through the decking.
Now here is the Cool trick.. take a coat hanger and snip the hook off. Flatten the wire out to a manageable size enough to make a "smashed Z". Your first bend is 5" ( this will go down into the hole you just drilled ) then up a little and then another angle bend so you can rotate the thing in the hole.
Your basically making an inside compass to see if your going to hit a bulky or stringer.
Stick that baby down in the hole and Spin the hanger 360 deg. .. if you hit something then re-drill over a bit. ( remember that these little drill holes are going to be cut out of your 8" hole so you should have some wiggle room to move your pilot holes a few inches.
I hope you know what im saying here
..
YD.
