Pinning dried flies

I've a number of dried out specimens that need pinning.
I'm not too bothered about splaying them out for ease of identification, I'll just struggle.
I'd just like to pin and stage them.
Does anyone have any tips for doing this job safely? I have fears of shattering the specimen whilst driving a minuten through it.

Re: Pinning dried flies

How about relaxing them with chopped Laurel leaves, then pinning?
Alternatively just in a box on damp tissue paper, if the laurel leaves are mow too mature to produce enough HCN for longer term storage.
I think there have been articles on this and related subjects in the Dipterists Handbook and DF Bulletin.

Re: Pinning dried flies

If they're small, I'd advise card pointing. If they're larger, they should be relaxed before pinning, and your pin may need a bit of glue, as the contents of a relaxed thorax are never as sticky as a fresh one.

Re: Pinning dried flies

No substitute for the old tried and tested methods then. I tried a simple "steam box" as Ken suggests - well it's nearly steam in these temperatures of around 25C.
At one time in the past I added some horrendous stuff to the water to prevent fungal growth. Phenol is one (a formula from Ray Wooff), amongst the most frightening chemicals I've ever dealt with, you have to protect your breathing and all exposed skin surfaces then scrub down afterwards as the crystals in the jar break free and float around in the air then burn deeply. I read about acetic acid as a fungal preventative so I just added a few drops of white vinegar (which doesn't work I discovered)
Most things fix muscle tissue and make joints unbendable but a day was enough to relax them without that happening and the dry stuff which was given to me at Stafford relaxed nicely. Never as good as freshly killed but then no-one's out to win prizes.
