How much spacing are you going to place between the poles? I usually play on a 50x50 board (I think), so I'm trying to work out how many would look suitable. I suppose in a town board there'd be more in use than say by the roadside out in the back o' beyond. What's the material like? I may see about hacking up a few of any I buy.
$9? What really? Those are 28mm? Damn that's cheap.
Not sure about the spacing. I probably thought it over before I ordered 20 of those poles

Material rather hard plastic. I glued everything with 2C-expoxy as modelling glue didn't seem do the trick. (so probably no styrene)
They measure 7" so definitly 28mm material.
They do need some cleaning up :
some displacement of the mold halves mainly noticable on some poles and horizontal beams.
imprints of the ejector pins on the beams (I filed those away) and a big one between the 2 sets of bolts on the pole (can be seen in the closeup since I felt these are to deep to cover up)
Also the isolators are flat on the back (front left pole in the group shot)
