Hi Bart Paul and Dan
Paul -I find with a single 3oz you cant dent it with your fingers,I should add that my pre seal on the outside is a very light coat and I dont increase the density of high ware areas of my own boards however it has merit if you are doing boards for others or you have an area of uour board that you know you punish
I used to use 4oz then went to 3 oz in a bid to find the breaking point
I am using balsa
Core densityif you look at the pvc core materials such as dcell you will find that the densitys vary you can get very soft right thu to unbeliviably hard ,they are all for use in sandwich construction.The softer the core the more the flex of the sandwich panel and vis versa.
Quite often it can be a trade off between thicker laminate skins vs denser core material vs thickness of core material
There are just so many variations to pick from!
Im not sure of the figures you want?
See the note below on the inside skin
no i havnt been venting though i should be venting even more so now summer is here
I think that we are very lucky here the temps are not that extreme, at xmas we are going to vist the folks in Perth so i will have to put vents in for there temps
The eps I use is the light stuff
Bart - Yes thats the total mixed and thined amount
And yes its all a chain part a connects to part b etc
Your lam is bonded to the sealer but the sealer has bonded to the balsa
It can give a better deeper bond than just a surface bond
In any construction all materials should be compatiable
Its not so important on the inside skin as the vacuum takes care of bonding issues
Beware there is a difference between sealing and saturating a porous material
Dan
I havnt looked at that I would check with your epoxy dealer they will be able to advise you about what there product can and cant be thined with
To every one beware where you use thined epoxy as thining it does affect is strength
