I knowingly bought a cracked Haro Circuit board plate as I could see that the crack was clean (mmm clean crack) and no plastic was missing ensuring a tight fit when bonding... However, I tried superglue and it did fook all - it might as well have been water.

I don't want to use the ray beams that I can fire from my eyes as I don't want to show off so does anyone have a suggestion as to a suitable bonding agent - I tired hugs but that didn't work either.

I have thought a plastic epoxy would be the ticket.

You need to know what material it is to get a decent bond Chris.
Most plastics bond poorly and if its a thermoplastic its worse. The good news is that once you know the material there will probably be an industry standard adhesive/solvent. Generally speaking anything you can buy in the shops will only give you limited success.

If it is a thermoplastic use tensol..

How can I tell what plastic it is Clint?

I've asked it but its pretending either it can't hear me or it can't talk...

Seriously though, does anyone know what plastic Haro used for their Circuit Board plate?

oldschoolace · « **Reply #5 on:** November 25, 2013, 07:28 PM »

Just had a quick look Chris and there is no obvious answer on the net. Someone on the museum is bound to know, failing that contact Haro, you never know they may be able to help $:-\$

I would expect it to be some kind of nylon but there was alot of experimentation with plastics back then and this ad claims Haro used something different to cast the plates.

Thanks Clint, lets see what I can find out.

I've used Acetone in the past.. don't know if it'll work for all plastics though.

oldschoolace · « **Reply #8 on:** November 25, 2013, 07:37 PM »

acetone is great on acrylic.... if my GCSE CDT head recalls properly.

May be worth a try with the solvent weld stuff you use on plumbing too. (though would be bloody carefull with it!!!!)

Jaan · « **Reply #9 on:** November 25, 2013, 07:40 PM »

I've posted on the Museum and contacted Haro, hopefully i'll get an answer that aligns with yours.

I'm worried about your "careful" comment though Clint, I can't tighten a wheel nut without taking a chunk out of the solid wood floor...

Chloroform. . . No joke

If they tell you it was made out of unobtanium tell them to fook off

Duly noted, but Kryptonite is ok?

Think you can use the two part epoxy on kryptonite

All jokes on the side hopefully they can tell you what it is as there seems to be a few on here who know about gluing plastics.

Getting this thread back on track, there are 2 Tensol options, could someone tell me if I need Tensol 12 or Tensol 70?

Chris

Just to check, did you allow time for the superglue to 'cure' before trying to stick it
My proto plate had a tiny split in it, but after a dab of superglue I waited for a short while and then pressed together
It is just like water until the point where it goes tacky though

If you want to test how long it takes, just put some on your fingers and see how long it takes for them to bond to things

I've stuck my fingers together a few times, I even do it for fun if i'm really bored but picking it off your skin is nowhere near as much fun as the glue we used to use as kids in school, and I don't mean Copydex which smells like a female tramps undies

I'll try again at the weekend, in the meantime i'm going to practice being patient

I use to work somewhere about a year ago, we used locative superglue. Now I thought superglue was superglue, but we had about 4 different types. One was specifically for plastic. I only found this out when I had a similar problem, I'll try and find the number .....the standard stuff is 401 Universal ( crap on plastic) might be worth a google. I'll get back to you if I find the number.

I reckon the stuff I was thinking of was 406 on the list.

Thanks mate, thats a long list of adhesives!
