Epoxies work good in some cases, even with bakelite and phenolics. All in what you have to do I guess. Maybe that's why they say to try the product in an inconspicuous area before committing to the whole job? Cyanoacrylates don't seem to work worth a crap anymore, I doubt you'd find a person willing to hang from a helmet glued to a steel beam with it anymore.

I just call 3M and ask for samples. Or buy it, even, if it's not ridiculous pricing. The 3M reps in my area are very accomodating. And if you're not exactly what kind of product you need, they'll be happy to discuss it with you. I needed some cyanoacylate to hold down 30ga mod wires on a PCB. I wanted something that was removable (peelable, they call it), set quickly (under 30 seconds), and didn't require a hardener or accelerant. Pronto CA8 Instant Adhesive was the recommendation. Pretty good stuff, except for it does that "super glue fingerprint" thing, where any fingerprint oils on the board near where you put it down are highlighted by the fumes. --John

I used to work with a woman that did that to her husband. I thought that was an urban legend, but she carried the article She was a fiesty woman, and I used to think it was funny that she and a couple other older women (they were in their 50's) in the group would get together regularly and play poker and drink beer until 3 or 4 in the morning, then show up to work at 5:30! -- Eric Dittman dittman(a)dittman.net Check out the DEC Enthusiasts Club at http://www.dittman.net/

Use the cleaning solution first - it opens the surface and while the plastic is still soft you can use the adhesive and it will be even more amazing, and faster. Best bet for plastics like models is toluene based glues, which our glue-sniffing friends of years past have pretty much gotten pulled from the market and replaced with worthless non-sniff glues. Testor's was pretty good way back when, now it just holds the parts together without actually bonding the plastic parts to each other. => -----Original Message----- => From: owner-classiccmp(a)classiccmp.org => [mailto:owner-classiccmp@classiccmp.org]On Behalf Of Curt Vendel => Sent: Monday, February 18, 2002 5:52 PM => To: classiccmp(a)classiccmp.org => Subject: Re: 3M Super Strength Adhevise SUCKS! => => => Go to your local Home Depot or Lowes.... go to the PVC Plumbing => section and => by some of the PVC fitting glue, that stuff is amazing, you put => two pieces => of plastic together with that stuff and they are NEVER coming => apart again. => => => Curt => => => ----- Original Message ----- => From: "Tothwolf" <tothwolf(a)concentric.net> => To: "Classic Computers Mailing List" <classiccmp(a)classiccmp.org> => Sent: Monday, February 18, 2002 6:28 PM => Subject: Re: 3M Super Strength Adhevise SUCKS! => => => > On Mon, 18 Feb 2002, Vintage Computer Festival wrote: => > => > > Just wanted to let everyone know that 3M Super Strength Adhevise is => > > absolutely THE WORST adhesive to use on plastics.

Obviously the Red Green Show is showing down there. I didn't know they had exported it south of the border. One of the better shows produced in Canada. Lawrence Reply to: lgwalker(a)mts.net

Yeah he became a major character in another drama series on stockbrokers. He's really quite an excellent actor and in this his character is totally different Lawrence Reply to: lgwalker(a)mts.net
