Paper putty

Years ago, my grandfather use to do carpentry as a hobby. He would save all of the saw dust during (and after) his projects. If he needed any wood putty, he would take some of the saw dust and mix in some wood glue to the thickness that he needed and then use it to fill in the hole, gap, or what ever space he needed to fill. Afterwards, he would sand it smooth, and then treat it accordingly. (I am certain that some of you old timers out there know of this technique, so this is nothing new to you.)

I decided that the same technique could be applied to paper modeling. Of course, using paper "dust".
Just save the paper dust in a small bowl as you are sanding the parts that you need for other models (or you can just take scrap paper and sand it into dust). (NOTE: If you have a DRUMMEL DRILL, this will make the process easier and quicker) Save it in a seal-able container and use as needed.

Here is a small (and simple) demonstration of what to do

I have edge glue three panels together.

Portioned out some paper dust.

Added white glue (it is easier to work with for this technique).

Mixed well (and added either more dust or more glue for the right thickness).

Applied to the joined areas (like caulking or Spackle). Let dry, the treat as needed.

This putty (or paste) can also be used to re-enforce contoured edge glued parts (where glue strips are hard to apply).
To fill in gaps, holes, strengthen other joints, or even make other smaller contour shapes that are needed.

The uses for this stuff are endless. Use you imagination and enjoy!!!

Verrrrry interesting. Straight white glue shrinks down quite a bit. Would you be able to make an estimation of the percentage of shrink one can expect with your paper putty forumula (I realize that it will depend on the ratio of paper dust to glue, but a ballpark estimate would be helpful). Can we see a photo of your 3 sided box after the applied paper putty has hardened?

Dear List folks:
with water color or water based paints you can tint the paste also. Nice Idea about the sanding drum on the dremal drill sure would beat doing it by hand with a fingernail file. works with Elinees tacky glue too. Just mix till it feels right easy to add more glue or paper dust.
Dear Rhaven:
Nice Pictures!!!!!!!!!
Thanks
MILES

Here is a photo of it dried (yes, I did apply it quit liberally. I was trying to make the corner a little contoured). There really was very little shrinkage. Most of it was do to the paper fibers mixed with the glue.

This will work with most any white glue.
I am glad that you like it.

I am glad you like the technique.
I know that there are other products out there like the one that you mentioned, but this technique is for those who may not have access to those kind of products, or who have extra scrap card and want to use it up.
I am looking forward to seeing your work.

Have been using the wood dust paste on ship models as a filler. Works great.

Thanks for the tip on paper dust paste filler for paper models.
Will come in very handy.

Regards,
Fred

brilliant!
and also a good way not to waste paper.
it might be feasable to use in-process as the glue, scraping excess off while it dries.
i did that making skimboards and surfboards to save sanding time.

For making small amounts of "paper dust" I've rolled paper tightly into sticks, which are ground against a file or rasp.
IIRC the commercial CelluClay is essentially powdered cellulose plus powder glue - just add water.

I did the same thing to make my stock of paper dust.
I made enough dust in advance to have when I need it.
When I have extra paper scraps, I will replenish my dust supply (that way, I have little waste).
