actually drilling the center is the recommended procedure before using the screw.... sometimes I do and sometimes I don't... drilling works better and leaves less chance that the bung will expand as you screw it in and push the edges of the hole sideways enough to deform or break the edges of the hole. You want to use a long but small diameter screw preferably also. probably a #6

Yes it makes sense. Do you use a drill to initially get the screw in?

usually I take a screw and and run it into the center of the bung.. when it hits the underlying screw it will push the bung out of the hole as it gets stopped by the underlying screw and keeps turning.If the whole bung doesn't come out and there are pieces left you just use the tip of a knife or a small flat bladed screw driver to carefully pop the remaints of the bung out.

Ouch... just reading my description hurts my head.. I hope you get a sense of what I am trying to say.

How are you guys taking the wood bungs out on the butterfly hatch? I just pulled mine off last week. I've got the varnish all stripped off but those suckers are not coming out. One I got out but stripped the screw (apparently). My drill just obliterates them and I was trying to use the dremel to get in just to break up the bung and it got stuck and overheated and wouldn't start again! Definitely has been frustrating.

I bought it from Acme ... ( why yes, I was standing in line behind a Wylie Coyote :p )

The terminology they used for it was "CACE30 in stock in black color 40 durometer silicone 30 foot minimum at $4.00 per foot "

It's referred to as an "E" profile gasket... looking at a cross section, it appears to be a lower case "e" .

The email for Acme is : info@acmerubber.com, as I remember I called them and gave a credit card # over the phone for it, I dealt with a gentleman named Ray, was very helpful and knowledgeable.

BTW, this is also the gasket that was on my forward hatch, where the wood mated with the fiberglass. Out of the 30 feet, I probably still have about 10 feet left.

My Plexiglass was 1/4 thickness, which I used the same again... that's thicker than most aircraft windscreens, so I considered it adequate.

Oh, I see, the gasket is seated into the gutter or relief. That does look pretty much like mine. Except I dont have the cool looking protective bars over the windows. It's just 1/2 " plexiglass.

Does anyone know where I can buy this gasket?

PS: Very nice restoration work!! The photo's are very helpful. Thanks!

As with all things DownEaster I'm sure there are variants of the gasket arrangement for the hatch…. we used to call it a Greenhouse Hatch. Mine had a 1/2" wide relief routed into the top edge of the base of the hatch, about 1/8" deep, with a gasket stapled into the relief. There was an approx. 5/8 half round "gutter" running under the hinges as well. I was able to find an exact replacement of the gasket ( I'll dig up the info if you would like ). The original staples were steel ( EGADS!)..but I've found that Monel and Stainless ones are readily available.

I've got a couple of pictures of it up at lastfarewell.smugmug.com/Projects

(I had to take the http:// off the URL, as for some reason it decided to start playing a slideshow of every picture on my album..just copy and paste)

It is on all sides and I have been thinking about it and think maybe it is not attached to the opening sections but to the body.. lol... having trouble picturing it in my head.

D shape? Is it along the edge with the piano hinge on it at the top? That's where mine is leaking from right now. There's a kind of built in gutter along the top and sides edges that the window closes over. I guess this routes most of the water out from the window.

Yes ours have weather stripping. Its just a D shaped one glued to the underside of the the window sections that hinge up I believe... Would have to look to double check that though...

Hello

I rebuilt my butterfly hatch but did not put any weather stripping on the underside of the little doors with the window panes in them. Mostly because the old one did not have any weather stripping. Do others with this butterfly hatch have any kind of weather stripping on the underside of the doors to help prevent leaking?
