Question - Full Backs 1 1

[conan09279]

Hi,

I just got a new set of E Gerber fullbacks from Amazon and the back is brown as opposed to white like all my other fullbacks. Is this new or did I get a bad batch? They also seem thinner than my older ones. Just curious.

E-Gerber web site describes FBs as "one side white."  HBs still say white on both sides.

Thanks man! Wonder why they went that route.

No idea and I agree it looks kind of strange now  Personally, I buy HBs in bulk and use two per book.  They are actually less expensive in bulk than the the FBs and two per book are thicker than one FB.

2K Standard HBs (24 mil ea) = $159

1K Standard FBs (42 mil ea) = $192

When I was ordering direct from EGerber, they described the available FBs that way, but they didn't say why the change, nor did I ask.

That is correct: two 24-mil HBs placed on top of one another will be thicker than one 42-mil FB.    However, the single FB will still have the greatest flexural rigidity (or resistance to bending).  A glue lam beam "works" because the individual laminae are glued together to prevent sliding between layers.  Without that glue, there can be no shear transfer.  The stacked layers would no longer behave as a single unit.  Glue lam beams "work" because of the glue, not because of the number of layers.  Class dismissed.

My masculinity level just dropped a level ... no idea what your talking about.

You had me at flexural rigidity and glue lam beam. Nice to learn something new.

What’s a glue lam beam

Those are butt-arse ugly........makes them look like cheap junk now. 

WTF us wrong with companies these days?  It's like they're all trying to win the world record for dumbest idea.

Looking forward to the introduction of New Coke 2.

At least maybe the dumb-arses will use the right side against the book now.

I totally agree. That’s why I thought it had to be a mistake. It makes my books look off. That said, I can live with it. But I can imagine that this will drive some collectors absolutely nuts.

I suspect this is all a clever marketing ploy to force collectors with OCD to buy all new boards so they all have the brown backs because they can't stand to have some books with white and some with brown.

I worked with a carpenter once who was convinced two 2x6’s standing side by side were as good as one 2x12 on edge. I made some quick sketches and wrote some simplified formulae on a wall and identified the area moment of inertia as being key in comparing the two configurations. For many years after that, he’d never say “hello;” instead, he’d point to me and bellow “one-twelfth b h-cubed.”

When I ordered direct two weeks ago, I was informed that FBs were white only on one side now because their supplier could not do both. It sounds odd, but given all the crazy supply chain disruptions that have taken place in the last few years anything seems possible. I saw some of the new boards a few months ago on a dealer's table and my first thought was "Are these legit?"

Regarding my order, I was told it would take about 10 weeks, but it was processed 7 days later and bags and boards were in hand a few days after that.

Those look weird. Looks like they are still calling them 100% acid free and archival. I guess safe to assume only if your book is on the white “coated” side?

Looks like they found a new cheaper supplier.

Was thinking about placing an order. As long as they still meet their quality standards and aren’t thinner.

The guy I get supplies from has been trying to get these for months, and now that they are back in stock he was warned that only one side is white. Gerber told him it was to keep the costs down plus they could not source the proper materials.

I matched them up with older ones and they are the same thickness.  They don't seem as sturdy, however.
