I´m thinking mostly of stainless steel and Ti, whats the best for gluing ss to Ti, and ss to ss, Ti to Ti etc?

I was thinking epoxy, but there are load of different epoxies out there, what am I looking for (I´m sure it will be hard to find certain brands and grades etc)? Does epoxies follow some sort of standard so I can find an equivalent if I can´t find the right brand?

What else is out there? Polyurethane, will that work?
 
Epoxies are your best option (in my opinion) Epoxy is pretty much epoxy and the main thing that changes is actually the fillers and hardeners. Most of the different versions are for different applications such as wood, brick, plastic etc.

We have a good local supplier in ABE but you must have other suppliers such as Henkel etc. Contact them and ask which version is better for your application. I dont think there is any sort of standard that all manufacturers follow. If you have flush surfaces you want a relatively thin glue, and probably the most important thing is to roughen up the mating surfaces before gluing with a bit of sandpaper.

Polyurethane is pretty good but not my favourite.
 
Anyone else? I think I will have to try epoxy first to see if it works out all right, hopefully it will work out just fine.
 
Try some JB Weld, available in most auto supply houses and other places. It is pretty tough stuff and not that all expensive.
 
We use 3M Scotch-weld a lot on aircraft metal to metal applications part number 2216 B/A grey.
Works well on planes and can be used to glue ceramics,wood,hard rubber and many plastics stays a little flexible as well.

"Aerospace" adhesives may be a good consideration, too. They are acrylics. You may read about some of the Loctite versions here:

They are slightly amber tinted when dried.

Some of these high-tech acrylics are tremendous.
Depending upon what you're doing, there's always VHB 'tape' from 3M.
This stuff is quite amazing--an acrylic microfoam in a form like tape that's only a few thousandths thick. They use it for fastenerless applications such as suspending giant glass overhangs at the Chicago airport. Strong, tough and shock resistant.
Acrylics can be truly impressive.

What color is this product? Also what do you use for cleanup with it? How much working time does it have?

Walter, it's grey colored. I didn't make a mess with it, so I really didn't have any clean up to do. I'm not sure of the working time, but there was more that enough time for me to get everything adjusted and clamped up. It says that it takes 48hrs to reach maximum strength.

I checked the labels. They say that it cleans up with MEK, Laquer Thinner, or solvent Alcohol. The labels also warn you to wear gloves.

P.S. I just scanned the glob that I had left over (I mixed way too much). The color in the image is pretty close to the actual color of the glob.
