Honeycomb questions

[Rogerogrant]

Hey y’all!

A couple of quick questions regarding honecomb as a core material:

1) What is the best strategy for running fasteners through it (i.e., should one overdrill and epoxy fill to prevent h2o intrusion or other reasons)?

2) It seems like kerfing and shaping it like D’cell or plywood would kind of defeat its purpose, but is that not correct? Alternatively would one be able to thermoform it?

These are idle, “just trying to educate myself” questions - I don’t know much about the stuff beyond its use as a core for more-or-less flat panels like soles and decks...

Thanks!!

Don't use honey comb to build. It gets soft on just a hot day. I enjoy chewing it when full of honey, but can't see it on a boat build

I think it’s a good source of fat and protein when you’re lost in the woods too!!

If there's larvae in it.

They taste like honey....

It is good stuff for decks and such but not for bulkheads, the line of stress is running the wrong way.
If you glass it on one side you can bend it a fair amount to do something like crown a deck. When you glass the other side it locks into shape. You get some sound and thermal insulation from it also. For attaching stuff to it I have been doing the over drill and fill thing. I then go over the fill spot with a couple layers of glass to help spread out the force.
The commercial fishing guys around here have taken to using it for their decks. 2 inch gives a light and stiff deck

Using 1" plascore for Skoota deks.

Stiff as a rock the way I laid it up. 42oz glass 3 tows two directions bottom. One triax top.

Thanks guys!

As I said I’m just asking so I have a better understanding of what it might or might not be acceptable for, but I was kind of thinking about it for a T-top (hardtop)....

I built a 8x5 T-top. I used 1/4 plywood for edging as you have to deal with the edge some how. It is stiff enough for me to walk on. It weighed 57lbs. I think I could have made it lighter if I had felt the need.

The wind is bad. The houseboat is bouncin. Yuk.

Picture at the end is xtra. Plascore has a veil on it. It uses quite a bit of resin. Probably 120% with glass weights.

Here you can see the panel is dogged to glue the high density on.
