I use it fairly often...

>There was one retail place in Tucson where I used to buy it, no clue yet where to get it now. Weldwood is the name. Brown powder which is mixed with water and brushed or better yet rolled on. Really good for bent laminations, as there is very little spring back, also good for veneer. Set time varies from 8 hours at 90F to 14 hours at 70F, which makes it too much of a pain for me to use where I could use TB or hide glue instead.
Couple of tips:
1. Be very careful not to use too much water (this is why they recommend mixing by weight in the instructions), it will drastically weaken the glue.
2. Mix with warm water. This stuff mixes much easier if the water is around 90F, forms more of a liquid than a horrible sticky mess, greatly reducing the temptation to add more water and ruin the batch.
Shelf life is short, as mentioned, though I've had a bucket sitting around almost two years now and its still good. The joys of a dry climate (its humidity that kills the glue, AFAIK).
Should be able to find it mail order if you google Weldwood.
