not enough hardner in west system 105 glue
I've made one if those silly mistakes, trying to get a job done. I've mixed a lot of west systems 105 glue together, which used up my last bit of slow hardner. At the time the voice of common sense told me I didn't have enough hardner in it, but I pressed on.
Two days later and the glue hasn't still gone off. It is no longer runny, and has turned tacky and the surfaces can be pulled apart.
Has any one else had this problem or know of a solution?

Pull it apart, clean it off, start again, and remember that 'not enough hardener' generally means 'plenty of time to do it again'. Mixing ratio should be accurate, as a little bit less in a 5:1 mix makes a much bigger difference than it does in a 1:1 or 2:1 mix.

Thanks master splinter, I have just taken your advice, pulled the pieces apart and cleaned up. I'll be ordering a new lot of glue with a measuring pot I've always been ok at guessing the amount and adding a bit extra just in case. This time I must have ran out of luck.

I'd recommend (if you tend to do smallish amounts) one of these sorts of mini-scales. - NEW 500G 0 01 Digital Pocket Scales Jewellery Precision Electronic Weight LAB | eBay
For 105/205 the mix ratio by weight is 5.19:1, with an acceptable range between 4.84:1 and 6.20:1

Hi
You have do the right thing by re doing it......Lesson learnt I hope...
I mix up small amount of epoxy and use the small jewelry scales and a shot plastic cup 5:1 ratio have mixed as small as 3gr. It's the way to go

You are not Robinso Carusoe mate
A year or so ago I made a custom Huon Pine corner bathroom vanity with cupboards and drawers galore. For some reason I cant explain (and still kick myself for) I mixed up 2 lots of part A for the final coat of lacquer rather than 1 part A and 1 part B. Needless to say by the next day it hadn't gone off,or by the next,or next.Took a while to dawn on me what must've happened...had to scrub the last coat off with steel wool and thinners. One hell of an unsavoury job. Made the whole job a hassle rather than a positive.
As the old George Thouroghgood song goes "You gotta lose, you cant win all the time"
Incidentally I have made even bigger blunders, but hey, no one wants to hear about them.

Artful bodger, a floor finisher told me of a similar mistake, where he mixed two parts of part A instead one part A and B. He said the only way to fix it was to take off socks and shoes and coat the undried varnish with part b.
