Martin Harris - Moderator Posted August 26, 2019 Share Posted August 26, 2019 Even I'm not using a fingertip to start off the setting process, I'm quite adept at puling my digits off a model's structure when the CA runs off unexpectedly. The most entertaining "accident" was when I'd been doing some modelling indoors and picked up a large handful of tools to take them back out to my workshop. Amongst the odds and end was a bottle of thin cyano and the inevitable happened...things started getting hot and I ended up like a budget version of Edward Scissorhands. 10 minutes of soaking in warm soapy water later, the tools were separated from my fingers and the finger picking could commence.

Kevin 216 Posted August 27, 2019 Share Posted August 27, 2019 Using the thin cyno = attached to Bench/model/tools/etc. Reminds me of the old Stealers Wheel song "Stuck in the middle with you glue" Quote Link to comment Share on other sites More sharing options...
Nigel R Posted August 27, 2019 Share Posted August 27, 2019 Some time ago I would have answered "every time". And, it beats me why there was a need to market "accelerator" for this stuff. Anyway. I recently discovered that 0.5mm ID PTFE tube is available on Ebay for a couple of pounds a metre. My fingers are much happier as a result.

Geoff S Posted September 3, 2019 Share Posted September 3, 2019 The first Cyano I came across was something called Eastman 910 (at least I assume it was Cyano) when it was used by the Instrument dept at RR to stick strain gauges on engine components under test on either rigs or actual engines. They used to fail as the test progressed so it wasn't perfect but it was probably the best available. That was in the 1970s/80s. I don't know what they use now - I've been retired 2 years Geoff Quote Link to comment Share on other sites More sharing options...
Douglas Groutage Posted September 5, 2019 Share Posted September 5, 2019 Just think what the fumes are doing to your sinuses and internal parts. I have to wear a half face respirator to prevent my sinuses from congealing to a point I can't breath through my nose. Just a whiff will set them off. Its not an allergy it is the glue vapours literally setting my mucous membranes to semi-solid material. I use the stuff very sparingly. And I also have a fan blowing any fumes away from my face as the glue will also react in a minor way with my eyes as well. After an 'attack' three days later my breathing will be back to normal.

Don Fry Posted September 5, 2019 Share Posted September 5, 2019 Douglas, there is the old saying, only two things in life are constant, death and taxes. Only half right if powerful and rich enough. But still half right, and breathing is compulsory component of the right. Are you sure you should be using CA at all. Quote Link to comment Share on other sites More sharing options...
EvilC57 Posted September 5, 2019 Share Posted September 5, 2019 I find thin cyano to be particularly dangerous, the way it runs around joints and often seems to find my fingers. Makes 'er indoors laugh sometimes when I go indoors with a section of model firmly attached to my fingers, or two fingers stuck together. I've found the thing is not to panic, and if it's something like a balsa model that can't be put under a warm tap, the sweat from your fingers and a bit of pulling, or the edge of a blunt knife seems to naturally loosen things up after about 20 minutes.

Alan Hilton Posted September 9, 2019 Share Posted September 9, 2019 I used to work in the water industry as a operations manager , I used to get phoned at home a lot .One evening I was in my workshop building a manatilla when the phone went (I had an extension in the workshop) .Unfortunatly the aileron I was working on got stuck to my right index finger .The caller was a somewhat irate local councillor who went on and an for about half an hour while the aileron hung off my finger .I started to use latex gloves after this Alan Quote Link to comment Share on other sites More sharing options...
Foxfan Posted September 9, 2019 Share Posted September 9, 2019 Haha, I'd have just told him calmly that I couldn't speak while I had an aileron stuck to my hand and let him stew on that. After all, he's only a councillor! Martin Quote Link to comment Share on other sites More sharing options...

I don't know what they use now - I've been retired 2 years Geoff You've reminded me Geoff, I think I first came across a similar adhesive when I was working at Imperial College, London for a while, also in the mid 70s. The firm that I worked for engaged IC to do some very expensive strain gauge investigations on experimental light weight diecastings and I had to build up some very complex machinery PDQ after the strain gauges had been glued on so the equipment could be run and tested - it was very time dependent for some reason IIRC and quite a responsibility for a young technician in my early twenties. Happy days. Quote Link to comment Share on other sites More sharing options...
Foxfan Posted September 9, 2019 Share Posted September 9, 2019 First superglue I ever encountered was a tiny phial of reddish Loctite that came with the very complex MRRC 4 wheel drive 1/32nd scale slot car kits of the Marcedes W 154 and that was well back in the 60s. It was used on all the tiny screws to stop them vibrating apart when racing. Find one in its box today and you could buy a new Laser with the proceeds.

i12fly Posted September 9, 2019 Share Posted September 9, 2019 My bad experience was due to a poorly fitting capillary tube into the top of a large bottle of CA. I made the balsa joint OK but after, when I turned the bottle the right way up, escaped CA ran down the side of the bottle and glued 2 fingers and thumb to the bottle. Quite difficult to remove as I couldn't turn my hand over or the bottle would have emptied, I hadn't got any de-bonder or acetone either..... I kept me quiet with a sharp knife for about an hour Quote Link to comment Share on other sites More sharing options...
Foxfan Posted September 9, 2019 Share Posted September 9, 2019 Could you not just twist your fingers a little? CA has no strength in torsion, whatever, just tension and then it's good enough to repair a Hoover belt! My Unimat lathe drive belt was repaired in 3 places as I was too tight to buy a new one and it ran perfectly! Martin Quote Link to comment Share on other sites More sharing options...
i12fly Posted September 9, 2019 Share Posted September 9, 2019 Hmm.... Didn't realise torsion would help release. It would have helped release the thumb but the 2 fingers were stuck together as well as to the bottle so difficult to move. Did manage to get free without any blood spilt but I had a few sore patches..... Fortunately it was my right hand and I'm left handed, otherwise it would have been more difficult wielding the knife. I'm more careful now if I need to use CA, preferring Aliphatic where possible Quote Link to comment Share on other sites More sharing options...
Martin Harris - Moderator Posted September 9, 2019 Share Posted September 9, 2019 Too late now but warm soapy water will soften the bond within a few minutes. A bit awkward keeping it away from the bottle in this case but it's a bit less dramatic than hacking your fingers apart with a scalpel...

i12fly Posted September 9, 2019 Share Posted September 9, 2019 It's quite surprising how thick skin is on your finger tips if you've got very dry skin like me! It was all a few years ago and I now have a bottle of de-bonder, I've never had to use it (yet) and to be frank I'm not sure where it is and if I could find it now Quote Link to comment Share on other sites More sharing options...

Andrew Jones 12 Posted March 27, 2020 Share Posted March 27, 2020 Posted by Foxfan on 26/08/2019 14:33:05: Our water heater system is rarely that hot, Chris and actually, since I do the washing up mainly, I find that water is ideal and by the time I've done the washing up with a scourer pad the glue has gone. Martin agree with you Quote Link to comment Share on other sites More sharing options...
john davidson 1 Posted March 27, 2020 Share Posted March 27, 2020 My worst experience was unknowingly getting ca on the heel of my left hand and then using kicker . The ca started boiling and there was nothing I could do about it, Very hot for a few seconds until the glue set but no pemanent burn Quote Link to comment Share on other sites More sharing options...
robert chamberlain Posted August 14, 2020 Share Posted August 14, 2020 I have gotten into the habit of using those thin exam gloves. They do tear easily and the glue sticks easily so it is a one shot deal. But then I don't use epoxy all that often. Same problem with CA.

Andy Stephenson Posted August 14, 2020 Share Posted August 14, 2020 I want to know why using acetone to loosen and remove CA is such a bad idea as was mentioned in an earlier post. After all it is the principal ingredient in nail polish remover and according to the MSDS I read it has no known health hazards. Andy.
