(...) Well... I tried to build a pentagon (using solid 2x5 structures in the middle) and I was not able to close it (too much tension). Perhaps with the bar and holes it would work ? Philo (21 years ago, 15-Sep-03, to lugnet.build.sculpture, FTX)

(...) Originally I thought of using 2x1 plates with one stud to get a 1/2 stud value, but your 6/5/5 idea is probably (much) better. The precise value is 6/5.1/5.1 so here the pentagons will be taut and flat. There is probably enough slack in the (...) (21 years ago, 15-Sep-03, to lugnet.build.sculpture, FTX)

Hi John, (...) Sure I do ! You say in (URL) text> "But for some reason I didn't realize that the flat faces of the pentagons would line up with the ajoining hexagon" Actually the problem is that triangle in the pentagons should not be equilateral.
