"Whatcha think Shreddy? You can see the dark area on the belly lam compared to the back glass....."

I was wondering what the dark area material is?

Stagmitis · « **Reply #145 on:** January 20, 2021, 08:47:52 AM »

Flem, Its the brown craft paper underneath the decorative one on the face.

Its a two lam maple core. I remember how excited I was when my mom bought this for me at Zayres department store

Hey max Formica is made with layers of craft paper ( same as brown paper bag material) infused with resin. The last layer is decorative.

Flem I know it looks thick but I think its the angle of the handle. Probably .50 or less. I can see the engineered paper layers if I look close. Darn thing even has a maple power lam extending about 5" past the fades Lol.

I like the unbraced profile too

Flem · « **Reply #152 on:** January 20, 2021, 10:06:48 AM »

They put glass under the Formica. Interesting. The Formica must be mostly cosmetic.
Now who would do something crazy like that. Like to see the numbers on that stuff. Wonder if the cognoscenti would approve

Mad Max · « **Reply #153 on:** January 20, 2021, 10:10:39 AM »

Formica is on the belly

Mad Max · « **Reply #154 on:** January 20, 2021, 10:19:03 AM »

Here is a different one.
They are not saying back and belly.
They are saying back and facing.

Flem · « **Reply #155 on:** January 20, 2021, 10:41:24 AM »

The Formica is only on the belly side Charles?

Stagmitis · « **Reply #156 on:** January 20, 2021, 10:54:13 AM »

Formica only on the belly. Back has linear white glass....

Flem · « **Reply #157 on:** January 20, 2021, 11:18:53 AM »

I wonder how craft paper and resin compares to epoxy and bubbles?

williwaw · « **Reply #158 on:** January 20, 2021, 03:32:23 PM »

you will have to find that out by trying, I suppose. It would be interesting to compare the density of formica to glass.

Flem, I read some where you have noticed density of laminates (glass/resin ratios) make a difference. Can you share more of your observations? Is it just the belly lams that it makes a difference on?

Roy from Pa · « **Reply #159 on:** January 20, 2021, 03:45:56 PM »

cognoscenti

Flem, stop using those words I gotta look up.

LOL
