Any suggestions for a thin fluid solvent based acrylic glue to mend some
damage on a largish 5cm diameter Perspex pipe for a science demo.

The end got bashed and it would be expensive to replace. The repair must
be waterproof and preferably clear and same RI as perspex.

I am tempted to try petrol or pet ether and hope that the end of the
crack doesn't run. Basically I need a low viscosity solvent glue that
will go into the fine crack by capillary action.

Most acrylic glues feel too thick for this job. Any suggestions?

Yes, chloroform should do it. The viscous perspex glue is often made by dissolving perspex in chloroform. Avoid acetone at all costs - it will make the perspex craze.

Dichloromethane (methylene chloride) (the active ingredient in old paint
remover.

Use a solvent, not a glue

be fine (don't inhale!)

+3. I've used chloroform many times on perspex: let a little run into
the joint and hold it closed while it melts the surfaces together and
evaporates. For a thicker, more 'gluey' approach, dissolve some perspex
shavings in it.

The seller grossly understates the dangers, perhaps to a similar extent to that handyman that removed the panel keeping kids from a 60' drop. I've no great concerns handling conc acids, but am very wary of chloroform.

Try a model shop which caters for serious makers of plastic kits; -
'Plasticweld' or something like that.

Yes, so?

This is dangerous;

Compared to, say, chlorine trifluoride;
http://pipeline.corante.com/archives..._this_time.php

the dangers of other substances tell us nothing about chloroform.

Chloroform is about as dangerous as peanut butter.

Er, no. Peanut butter is pretty safe for kids to handle. Chloroform is a volatile toxic carcinogenic general anaesthetic. It may not be a problem for folks with the necessary knowledge, but to put it on public sale without adequate warnings is irresponsible.

(Perhaps the fact that I have a (bio)chemistry degree biases my feelings
in the opposite direction to you?)

I've worked with it occasionally years ago, but no way would I sell it to any & every random stranger. Perhaps you would.

When was about 14 used to get ether by the half litre from local chemists, best switch cleaner about, used to ask that I get it late in the day because decanting it would stink the shop out.

Chloroform looks bargain priced aginst cost of ether on ebay nowadays...

We used it here for years but then H&S found it so useful they banned it, or at least put restrictions on it's storage and use, it was just too much hassle to keep.

I sure that peoole3 that work with plutoinium dion;t see that as dangerous otherwise they wouldn;t work with it.
