Re: Has anyone heard from Purdy Swoft
Sad to hear. I always looked out for his posts. Always helpful, always sensible and always very pleasant.

Re: Tom Wesenberg has Passed!!
A shock to me! One always hopes for the best, but in this case poor Tom was beset with too much to survive it seems. My heart goes out to Marilee, who held his hand as he died.

Terry, 5/32 is only a bit over 1/8 inch which, when I visualize that, sounds very thin for quite large areas cast in sand. Yet even in the Victorian era, they were able to produce some amazing cast...
