Styrene sheathing

[grandpopswalt]

I’m going to try my hand at scratchbuilding a 1:20.3 scale boxcar. I propose to build it using either 1/8’” tempered masonite or plywood. I’ll then cover the sides and ends with scribed .020” thick Evergreen styrene. My question is this ……. what adhesive should I use to laminate the styrene to the Masonite or plywood?

I use 3M #45 spray adhesive for all my laminating. I've never had any peel off, and use exactly the materials you're using--styrene or wood on top of masonite or plywood. You can also use their #77 adhesive, which is supposed to be stronger. I use #45 for mounting photographs, so it's what I had lying around. It's very easy to use. Spray it on both surfaces, wait a minute or two, then stick them together.

If you're using wood, stay away from carpenter's glue as a laminant. It will warp the side of the car something horrible. I wish I took a photo of the car side where I tried it, as it resembled a Pringle after a short fashion. No amount of weight or pressure would get the car side to lay flat again, so I had to toss it and build a new one.

K,

Could you give some brand names with those? I use super trim adhesive on a regular basis and I think that's #77. I think it would give alot of laymen a huge help in finding the product.

3M is the brand, I personally like I think it's the #33 over the #77. In having success with either sray one coat on the woul and let it dry then spray a second cost on the wood and plastic. The first coat on the wood acts as a primer due to the woods absorbtion. I think the # 33 is a contact cement more then just a spray adhesive after writing the above. Meaning the glue sticks to the glue.

Thanks guys. I just checked the adhesives locker and found a nearly full can of 3M #77.
I'll give it a try.

The 3M is really good stuff, if you are ever going to do a project where you will need a lot of adhesive, Liquid Nails is good. It comes in a tube like caulking and for light applications it goes a long way.
