Pete, i appreciate the fact you are doing much of the work youself, i.e., zinc plating, i will assume probably painting..
We have a very fine core of participating members who don't flaunt their egotism by talking down or taunting other BB participants.
There's anumber of of BB on any given website, but very few actual participting members.
People that really are interested in things sandcast, do, over time stick; even though they may have periods where their particiaption on the B waxes and wanes. Or, perhaps, i should speak for my self; i've been doing more waning than waxing !
