herein lies the brief description of how I build my own replica Tri-D chess set.
CHEAP Chessmen!
The cheapest, decent sized, set of chess I've found is $1U.S.and located in the local Walgreens store down the toy aisle.
It's a Fundex games item #2310 (UPC 45802 23101
the king is 2 9/16"
Attack board support posts are going to be cut from a 6 sided clear acrylic venetian blind replacement wand made by Home Trends bought at the local Wal*Mart- the item number is 2129889 (UPC 93478 03185) though I don't see it on their website. :-(
