Does anyone (beside me/Silverheels) have their overhead hatch
lenses screwed down into their aluminum frame, or do your hatches
simply rely on the adhesion of the bedding compound to hold the
lenses in place?Thanks,
Tor

No screws in any of mine. I don’t recall ever noticing a hatch with screws.
I would think with the proper goop holding the lenses that screws wouldn’t be necessary. In fact I wonder if drilling holes for the screws would create a stress point?

I haven’t seen it anywhere else, either. Probably done by the PO.

Was he/she one of those belt AND suspenders kind of boater? 🙂

Just the right Silka caulk, properly primed to both surfaces. The
forces of a wave, etc would push the plastic down onto the flange.
Unless you puts rocks in the boat and turned it over and shook it, not
likely the plastic could be pushed out.Pete

Dow 795 works great with less prep than the Sika products and runs $8.95 a tube on Amazon. It’s a commercial glazing adhesive used in large scale construction with enough flex to handle expansion/contraction of the disparate materials. I used it on my C&C after glowing recs in the C&C listserv.

The old original Bomar hatches had screws in addition to silicone or some
other bedding. In 1978 there weren’t the adhesives we have now. Dow Corning
795 is perfect for bedding without screws, so clean up the frames, tape,
apply the goop, put the lens in, spread goop, add if necessary, remove tape
and do not touch for at least a day. That’s the hardest part for me.Bob

That’s my plan, Bob. I’m putting in new lenses all around now and have decided not to bother drilling to screw them down. My Hull #17 probably got “original Bomar hatches” in 1978. The screws holes look too neat to have been done by the PO.

I bought a few tubes of Dow 795 for this project after asking on this forum and around my boat yard and getting the same vote of confidence from several smart guys. That said, Pete’s also one of the smartest and I’m sure Silkaflex (if that’s the name) would do as well.

It would. I’ve used it but the other is easier.

The 795 is fine. The Silkaflex is better. I have used both. The
Silkaflex has lasted much longer (and is still going strong).On 2/20/2015 6:41 PM, Silverheels via maillist wrote:
