Glue 'n Screw

[Charc]

Not until this summer had I been taught "Glue 'n Screw", or really glue n' anything. I was told a faster, such as a staple or screw, was not sufficient, and didn't really do much, and requires glue.

Prior to this, I'd never been taught that concept on attaching stuff together.

Back at my internship, I spent days on end shooting together studwalls with just staples, that were to last 4-8 weeks. Just another example of how everyone has their own way of doing things.

What do you guys do, and why?

There is a lot of "situational dependency" when dealing with glue. Let's say you're covering a studio flat with Luan, The staples are really only there to hold the luan on until the glue dries, or sets depending on what kind of glue you are using. Since a staple, nail or screw is a friction device it depends on the thickness of the materials it's penetrating to acheive it's bond, when stapling through a thin brittle material, luan, into a thicker denser material, 1x, you have a very weak bond and need the glue to adhere the larger surface area. Gluing end or butt joints doesn't do much as there is not enough surface area for the glue to create a serious bond.
Now in certain circumstances, it may be that you want to only staple the luan. This would be the case in a situation where you are going to be applying something like a thick texture, and want to be able to easily remove the luan after the show closes so you can re-use the frame of the flat. Of course this situation usually only comes up when you are building a bunch of standard size flats like 4x8 or 10 rather than the odd 2'3 1/4" by 12'2 3/16" flat.

I glue and staple flats. I just use 3" screws on platform frames and 1 5/8" screws to put the lids on. I only recently encountered platforms that were glued and screwed, and it made cannibalizing them very difficult. I'm sure there is a somewhat larger margin of safety if you glue the lid to the platform, but I have never had an unglued platform fall apart on me.

Unless I will be taking the set piece apart to reuse the wood or the legs/frame/cover (which doesn't happen that often, as alot of it goes in to stock as is), I'll glue almost everything. It makes for a better connection between the two pieces of wood, and really helps the joint hold up better. Think about it - with a screw, you have a connection at one place, with 3 screws, 3 points of connection. With glue, you make a connection (while it is not as strong) over the whole surface that you're connecting, which often keeps joints from coming loose and sliding around during the run of a show.

We go a bit beyond that here, but then again we are making scenery that should last for years, and survive a truck. If we are building a studio flat, we glue and staple it, if we are building a 4x8, we glue and nail it (with a pneumatic nailer, much faster). Beyond that, everything we build that will ever leave on a truck, is steel and then covered with a sheet good of some sort, and for that we use a nailer that we have absolutely fell in love with which is far superior then the traditional t-nail.

If you EVER cover steel platforms or flats, this is a must. Beats t-nails or god forbid tek screws any day.

I've got half a Butt ton of steel fraed cubes to make, I'm gonna look into one of those.

The main thing to keep in mind when using glued joints, is is not the quantity of glue that goes in, but the amount squeezed out - That counts!.
With butt joints on reusable pieces, I use the loose pin hinges ;-

especially when placing together flats & joining rostra to set pieces. Also I won't have nails on my mind & prefer not use them on sets & shy away from staples as much as I can.
keystones & gussets on joints also helps, by not just relying on glue 'n screw. Even with fixed joints, such as Tennant, Halving or Biscuit.

Nailing into steel??? What will they think of next?
Meanwhile, I'm turning on the hotplate under the double boiler of animal glue so I can size the muslin. Note to self: need to order another 25 lbs. of Cerulean Blue, where's that Gothic catalog?

You Know what that smell is ? It's Casein. God, I love the smell of Casein in the morning. I reminds me of.... Art.
