Best HARD glue for a chassis??

[Malakite]

Any ideas guys?  Thanks :-)

[Dojo Dave]

I've used two part epoxy on chassis lately and it worked well. Once it cures you can sand and shape. Paint it if necessary.

I've used UHU Plast Spezial - works really well.

[Malakite]

Thanks guys - any links to these glues that you use at all??.. Thank you in advance :-)

I used superglue recently on an off-road 4WD  (because I was desperate more than anything) and looks like it is okay so far. I haven't put it under too much stress mind you! I have another chassis so if it did break, I wasn't that bothered.

UHU: http://www.uhu.com/en/products/model-building-adhesives/detail/uhu-plast-spezial-1.html?step=35&cHash=5d376e551c8fb6fd72170083ceb34e74

Used it recently on my cracked Bruiser body. Even though it's old and brittle, I still decided to strip it one final time - and yes. It cracked. Not where I'd used Plast Spezial though.

I have the basic UHU but although it bonds things, it remains really sticky and doesn't go really hard s it's no good really!

If it's an ABS plastic tub chassis, how about ABS primer and cement from the plumbing department?  It's used for drain pipe joints and should work here too...  Just a thought.

How/where do you store your glue? I keep everything in the fridge (next to SWMBOs nail polish) and has never seen this issue.

Depending on the amount of damage and type of plastic involved, there are different methods coming to my mind.

For minor damage on Tamiya's polystyrene (PS) hard bodies, styrene glue as used by plastic modellers is good, since it welds the parts together, forming a good bond.

For larger damage, 2-part Epoxy and glass fibre reinforcements should be considered.

You can also weld styrene parts together using heat and PS rods:

Tamiya's hard bodyshells aren't made of ABS as far as I know (even though some product descriptions and advertisements say so), but some chassis parts are. You can see the type of plastic embossed on some newer cars as well as re-releases.

Thanks for the in depth help - Its a half split rear top of suspension on my Hornet chassis...what would you therefore recommend?

[Dojo Dave]

Spend a couple of quid and get a replacement tree. I have a whole rear end assembly should you need one. Just post the picture of the part that's broken. 

[Malakite]

Hi, Unfortunately its part of the main chassis look!...

[Fuijo]

You know that the chassis is probably not that much more expensive than some decent glue?

[GregM]

I should have read better...

now that I see the pictures, I'd either suggest a replacement chassis, or metal braces bolted on with two screws at either side.

[Malakite]

Hi Fuijo - thank you sir!  Yes this is true, but if I had the glue I guess it means then I have some for future repairs of all other issues?

ok sir - re: metal braces...any links to the kind of thing that you are suggesting at all??....

That would be a DIY job. A drill, a hacksaw and a file or two can make wondreous things

[racer1]

For the type of plastics that RC cars are generally made out of you will need a 2 part Epoxy. JB Weld makes one that is specifically made for plastics and it's the best non-industrial epoxy I've ever seen. 

I used it to glue a Stampede chassis back together about a year ago that I snapped out messing around in the freezing cold. It lasted about 9 mouths until I eventually swapped it out for another used one. 2 Part Epoxy is also great filling in stripped out holes in a chassis.  Just force it in there with a open paperclip then use a tiny drill bit to make a pilot hole. Works great. 

Like others have said. A replacement chassis is is about the same as a good epoxy so you might as well replace it.

That's fair enough of course. Bear in mind that most glues do very much have a shelf-life. Usually much less so than an un-crashed hornet chassis. Just a thought!

[Dojo Dave]

My last hornet chassis was 16-20 bucks. 

[Malakite]

New chassis ordered guys - thanks for all of your help :-)
