Preparing kraftpaper for pasting

[FREAKYDUTCHMEN]

Here's a little tutorial about how to prepare a kraftpaper sheet for pasting.

 

The prepared sheets can be safed for one or two days, so it's most efficient to prepare a couple of sheets to paste about 10 shells in 2 or 3 hours.

 

The short strips can be folded open and then they are ready to paste.

Very, very efficient. Nice video. I have to get a cutting tool like yours though, I'm with scissors, it's a pain

Why do you put wheat paste only on one side of the kraftpaper, and not on both sides? Isn't there any difference?

[FREAKYDUTCHMEN]

You want one side that sticks right? Would be a mess if you smear in both sides.

Maybe the wrong place to ask but is there any advantage to kraft paper with ridges? There's the even all around paper and then there's the type that has small ridges going through it. Here's some pictures:

No not really, virgin kraftpaper haves ridges most of the time, but I don't know why, maybe because it is mostly for packing purposes.

But there's also virgin paper without ridges, and if you care about looks you'd better off with normal brown kraftpaper.

With the ridgy stuff it's a little easier to keep track of which way the grain is facing, which is nice when making canister shells and some inserts, but not really critical.

 

Good tutorial. I never thought of premaking pasting paper. One of those simple time savers that seems so obvious after you've heard it. A perfect activity to do while waiting for stars to dry. I may make a stack of sheets like that for the next build day I have come summertime - With the exception that I would soak both sides, with is preferred for canister shells.

Do you find it necessary to break the paper before using it?

No not at all.

I've always thought soaking your pasting paper thorougly with the glue, would make a lot stronger pasting, because theoretically it would act something like fiberglass or carbon fiber with the glue being the resin.

[FREAKYDUTCHMEN]

In a certain way it's true, the paper acts as the fibers and the glue keeps it together.

But, kraftpaper is strong by itself (thats why it is called "kraft"paper), so there's no reason to make it even stronger with the wheat starch.

Just get the layers glued together.

 

Just try, and you'll see.

Neat little trick in folding and cutting the paper, I will definately try this. It takes so much gummed paper tape and kraft is so cheap this will be convenient and save money!
