Consider the pencil. A straight stick of wood. Could one
improve on this, possible reducing wood waste, possibly
allowing use of other wood types? At BUNGCO we delight
in our cedar pencils but we had to know if it could be
done.
The plywood pencil starts with an enormous flat sheet of
wood,
produced from a single log in the manner used to
make plywood. Rather than stack sheet upon sheet to
make plywood sheets, the sheets are daubed with glue and
then rolled concentrically into a cylinder, the graphite
stick in the center. It feels, looks, and sharpens like a
wood pencil!
BUNGCO is experimenting with sheets of recycled paper to
see if a paper pencil can work as well as one of cedar.

There are plenty of pencils made from recycled
paper. Not sure about rolled veneers, though. |
|
| |
Cool. Make sure you wrap it widdershins and put the eraser on the right end or your pencil sharpener will just wedge. |
|
| |
If you made another line out of sharpening shavings you could keep recycling them over and again. (OK so it would be a tiny bit of a con. You'd just sell a pot of glue, a lead, and a mold - which I spell as "mould" on Wednesdays. People would buy the *idea* of recycling this way from you, as long as you keep quiet about the glue. ) |
|
| |
You'd have to taper the end of the sheet in order to
not leave a void during the rolling process. Veneer
plies tend to be a little thick compared to a pencil
lead. |

It's Monday morning so I can't even be bothered to do a veneer-ial diseases joke. |
|
| |
I have some high-falutin art pencils that appear to be made
of MDF or even HDF. Definitely some kind of composite
wood that sharpens very cleanly and smoothly. Dunno
where I got 'em. |
|
| |
I very much appreciate the engineering tips. The
widdershins wrap makes sense. I think it should
suit
all - not sure if there are lefty pencil sharpeners. |
|
| |
The tapered sheet also makes sense. I think
veneers
are a couple of mm but even that would leave too
big a hole in the middle. |
|
| |
And selling the "idea" of recycling. Ideas are so
inexpensive! As demonstrated on this site. |
|
| |
There is a fictional movie titled "The Odd Life of
Timothy Green" in which his parents invent pencils
out of rolled leaves! |
|
| |
Wow, that's kind of rude...I'll fix it with a bun. |
|
| |
[bigsleep] You do realize that plywood/veneer is
different from particle, right? If you can show me
a single example of a wrapped veneer pencil, I'll be
very surprised. Unlike the ones you are talking
about, this would not be majority glue, and
would be considerably more energy efficient than
reconstituting wood waste. It would also be a
much more efficient use
of raw wood than traditional cut pencils. |
|
| |
And yes, I am aware of paper wrapped grease
pencils, which still aren't the same thing, although
conceptually similar. |
|
| |
So save a tiny bit of wood at the expense of more glue? Hardly seems worth it. You may not even save wood, as one can't perfectly veneer-ize an entire log without some waste. |
|
| |
Rolled paper pencils are WKTE [link]. |
|
| |
The amount of wood saved should be significant,
and the amount of extra glue used should be
minimal. A lot fewer saw cuts involved, minimal
secondary machining, and one thin layer of glue
won't be that much more than is needed to glue
pencil halves together. |
|
| |
And yes, paper pencils exist, and are produced a
lot more efficiently than the hand rolled versions
from that link, but that does require more glue,
and is only a good idea if you have the recycled
paper anyway. |
|
| |
OK, so one F. E. Blaisdell contemplated a pencil made from rolled thin wood veneer over 100 years ago [link]. It even sharpens itself. |
|
| |
I'm with [bigsleep] on this one. A quick search shows there's nothing new here. |
|
| |
Aside from an idea being WKTE, rudeness is more
wasting of people's time.There is polite way to tell
someone their idea is already baked, but to say that
the reading of ANY idea here is a waste of one's
time, then you shouldn't come to the hb to insult
others. (just my opinion which I'm sure is worth
nothing to [bigsleep]) |
|
| |
//you shouldn't come to the hb to insult others. // |
|
| |
Well, no, of course not - mockery, denigration and gratuitous prejudice
are at least as important. |
|
| |
I agree with you numbers [8th] & [21]...all for sport is
fun. I just felt that [bigs] was being rude, which isn't
fun or smart, just ugly. |
|

Hey [21Q], looks like he's building a giant
wooden rabbit … |

Because you can't bear not to have the last
