cpaul_d2004: The guy that created Grand Chess used to have a web site that had a link to where the set could be bought. In Europe if I remember right. I'm not sure if he has the site up any more though. It seems like I wasn't able to visit it the last time I went looking. When I did see the site a few years back, the pictures of the pieces looked nice.

The pieces would take some time to make your own if you want them to look like one made together set. Obviously you could do as Ed did when he first made some sets and cut and paste some pieces together.
The boards are fairly easy to make. I've been thinking of a way to make a board have three or more sizes. Somehow have an edge slide out, but still be solid when set up for play. It'd be easy to have two game sizes on one board, one on each side. So maybe I'll make a 10 × 10 on one side and an 8 × 10 on the other and just lug a regular Chess board around that I could also attach something to the back of. It'd certainly be possible to make a game table, if one was good at wood working and then you could make lots of different sized boards and keep the unused pieces under the table in a compartment for them. Not to practical to carry a table down to the park for a game or two though.
