I don't know much, but I know how to find Wikipedia: https://en.wikipedia.org/wiki/Gampi (https://en.wikipedia.org/wiki/Gampi)

Randy, as a Northwesterner, you should be asking if tissue paper that's handmade from hemp by young ladies with dreadlocks, cheek tattoos and multiple nose rings would work.

Do you have a source ?
Title: Re: Silkspan thought

There's a bunch of sources. I am thinking about buying a sampler I saw and see if any of it is useful. It's a fibrous paper and in the pictures, it looks like silkspan. In some cases, might be the same stuff. It ain't cheap, but might be a decent replacement.

This gives you an idea of the variation. Finding the right stuff may be interesting:

There's a Dick Blick store in Seattle, and maybe even a good independent or two.  It may be worth taking a wander through their paper aisle.

Gampi is good stuff, but lighter than regular Esaki tissue. Probably too light for normal controline use. FF friend, John Morrill wrote this article for our LA Gampi source: http://www.hiromipaper.com/newsletter/Planes.htm

Norm, I saw some stuff that looks pretty heavy. The link I posted had about 25 different types and I thought that at least some might be heavy enough to use. But I guess we'll see. Seems like SOMEONE must be using silkspan in other applications.

"Gampi" is just the fiber that the paper is made from.  So the paper itself could be any thickness (Dick Blick looks like they even have Gampi card stock).

Guess I should have checked sources before I wrote my previous reply!
The Gampi I'm familiar with was very fine Japanese tissue at a premium price. Used it for lightweight rubber models and F1B stabs etc.
The article John wrote was for Hiromi Paper Co. I see Hiromi now sells different weights of Gampi paper. Their catalog includes the weight in the description. See: http://store.hiromipaper.com/search.aspx?find=gampi (http://store.hiromipaper.com/search.aspx?find=gampi)

I see it's even sold on Amazon.

Thanks!

If you don't have open bays, just about any of those fibred shiny one sided white papers will work for filling grain and adding a little strength, which is all we are trying to accomplish...

I experimented with the gift stuffing paper you crumple up and shove in the bag... cheap no-name stuff I got at BigLots.

Put it on a piece of scrap balsa and built up a full finish with some dope per usual, and it worked fine. As long as it dries tight and dope penetrates it, I'd imagine it would work fine on fully sheeted surfaces.

Now, open bays are probably a whole other story, but I've avoided open bay structures for quite some time now. If I HAD to do open bays again, I'd prolly do like I did on my Avanti. Put a piece of Phil Cartiers SLC film just large enough to cover the open bay and beyond by 1" larger, then put paper over the whole wing. This lets you build a traditional looking finish over the film, and is darn near bullet proof. You can't see where the film stops, it is so thin a coat of dope hides it.

Hope that helps,

EricV

Bill,

Look at the links above. I went ahead and ordered one of the sample books. We'll see what I get. I've got about 50 sheets of GM sig laying around (bought at a hobby shop going out of business sale). If I can find something for open bays, I'm pretty well set.

Open bays?  I can't imagine anything better than Polyspan.  I haven't tried SLC, mainly because I still have a large stash of Polyspan.  Like Eric says, almost any fibred materials work for solid structure.  The aforementioned polyester material works but is a little tougher to do.  Being basically cheap, I like Eric's idea.

 I think that's the stuff Brodak sells.

I've always thought that the paper used in teabags is pretty much silkspan. Shame we can't find their supplier.
