Damian,

That is a great idea, and while obvious in hindsight, never occured to me
before you mentioned it! Thanks!

3M 4200 will work, but if the fitting is plastic, chances are you will be 
replacing it again someday. 4200 is not as difficult as 5200, but neither is 
easy to remove. Above the waterline through hulls are the only place that I use

I'm going to be drilling a hole in the hull to install a
well-above-the-waterline thruhull for a bilge pump discharge hose. The
thruhull is 1 1/8" inch, so I'm going to use a 1 1/4" hole saw drill bit.
I'm going to seal it with 3m 4200. Does this plan make sense? Are there any

Re: Stus-List Drilling a Hole in the Hull (Sam Salter)

2017-04-05 Thread Sam Salter via CnC-List
My thoughts are:
When you drill a hole with a hole saw it’s going to be a little larger anyway. 
But I don’t see the need for clearance – you want a fairly tight, solid fit. 
Lots of “goop” (...a technical term!) doesn’t seal any better. The seal is one 
molecule wide between the hull and sealant and one molecule wide between the 
sealant and the through hull. The rest is just mess to clean up! The seal will 
be on the through hull flange (on the outside) and the washer on the inside. 
Therefore any extra sealant in a larger hole would be redundant.

(I hate silicone and I hate butyl! ☹)
...jut sayin’ 😊

Sam, 
Actually, your question is something I would like to hear the list's thoughts 
on. I've read that you should drill the hole a size larger than the thruhull, 
but I have no idea if that is best practice or not. Should I be drilling the 
hole the same size as the thruhull, or should it be a little larger?

Just a caution on using a hole saw.  You shouldn't have a problem with a 1
1/4 hole saw but when using a larger one you should use a drill with a side
handle.  I have a corded 1/2 inch drill with a side handle that I use for
all hole saw work.  A broken wrist could be painful.  :)

Hi Joel,

I’d run the holesaw in reverse to lightly go through the gelcoat. Once you have 
a good clean pilot hole, you could start out side and likely finish from 
outside.  Hole saws can be wicked in close quarters, and you don’t want to 
enlarge your pilot hole before you make your “clean cut”.

2 cents, Lee
