Had a nasty experience today. I got a couple of Lie Nielsen planes as a retirement present from school (#62, #66) which go nicely with my LN #95 and #60½. So that I can take them over to France next week, I needed a case. As it happens we were cleaning out the loft, and I found a couple of foam-filled flight cases. Ideal, I thought. So I spent Saturday morning cutting up foam and sticking it down with hot glue, burning myself and making a shocking mess. Finished and put the cases to one side, planes inside.

This afternoon (Tuesday!) I got the block plane out and it was rusted all over! The jack had some marks on it, a Record 077 was stained, the bronze on the #95 looked tarnished. So, a lot of work with fine emery (I thought of lapping, but I don't think a light rub will have taken the soles out of true) and some new wooden cases made!

Not a pleasant discovery. Any ideas - is it the foam, the glue, or the metal cases? The humidity in the workshop has been about 50% this week.
 
Not nice :( I imagine those cases are pretty air-tight so it could be that moisture had been trapped in the foam for some time. Another possibility is that I think some plastic-type materials give off fumes - that might have had something to do with it.

Cheers :wink:

The fumes were my first suspicion - also volatile outgassing from the hot melt glue. That might explain the tarnish on the bronze and staining on the very old metal of the 077. And for it to take hold so very quickly. Pity I didn't think of it sooner...

Wood and dessicant gel from now on!
 
I am not an expert on foams but the foam lining in the box container of (my then expensive) Thorntons drawing set (compasses etc) turned into a black sticky mess over time.
I did buy it about 50 years ago, but I have always been wary of foams ever since!

Some plastics fume cloride, hydrochloric acid and alike, especially when heated.
