Foamular Adhesives and Properties
« on: May 18, 2019, 03:03:58 PM »
I am about to repair a broken FOIL BOX. 

I am taking OUT 2 tracks and putting in a Tuttle Box.

This will be my 4th Tuttle installation and/or repair  :o

The plan is to use the Purple Foamular from Home Depot as the foam substrate and to then cut out a cavity for a tuttle box.

I will use Gorilla Glue to laminate the 2 X 1" Foamular layers, 2" thick to fill the void, and then install the Tuttle Box into a hole I will route through the purple foam in the board. 

I have found evidence that Gorilla glue will adhere to the Foamular.  I am hoping that the Epoxy and Glass / Carbon will also adhere.

Any experienced perspectives welcome.

I am optimistic this will

1) Save weight or be weight neutral on the board alone.  A Tuttle weighs ~ 13 oz.  Each Track is 6 oz

2) Be Stronger.  I have installed Tuttles that have withstood massive abuse. 

3) Reduce the weight of this total rig because I can eliminate the need for the adapter on my GoFoils.

Any love here? 

Going to start putting this together soon.  Will the epoxy adhere effectively to the foamular?

Don't have any practical experience with Foamular but it is an XPS.  (XPS got a bad rap in the industry for gassing out and causing delams.)  But, with such a small area of Foamular, is gassing really going to be an issue here?

I think the key is bonding the top deck to the bottom skin with the actual Tuttle box.

This is good information Bean.  If outgassing is the only problem I 'should' be ok using for a small patch.

I think this Foamular stuff is more dense and durable than beer cooler foam which may make it a decent cassette around the already surrrounded tuttle cassette.

More on the top vs. bottom deck later.  But I have evidence that all the hold is coming from the TOP deck.  The bottom needs to be solid but if the top is bombproof the rig holds together.
