10 10 302 S - Maximum spacing of cross bearers
Gerald -
The plans call for a quanity of 8 cross bearers but there isn't a note as to the maximum spacing. So, it seems that 1ft, on center spacing is reasonable but some of the longer X table lengths leave some gaps (distances in feet): X Length Distance between cross bearer o.c. 8.00 1 9.00 1.125 10.00 1.25 11.00 1.375 12.00 1.5 13.00 1.625 14.00 1.75 15.00 1.875 16.00 2 Is there a magic on center distance that shouldn't been exceeded before another cross bearer is required? Thanks, david |
See dwg 10 10 123 D
Keep the spacing in the range of about 14" to 16" 8 cross bearers will not give you a 1 ft spacing ;) |
How I arrived at 1ft was by an X of 97 inches divided by 8 (actually equal distances) cross bearers. Thanks - I didn't even think to look on that sheet. It looks like 13.7" spacing - I'll use that in my formula for determining the number of cross bearers.
Thanks! david |
