Home made "NSN" chocks.
The PS mag NSN for the bolt would confirm 'their' width.
In any event, I went with your dims, 5 pieces wide, but hardware store didn't have 8 1/2" bolts, so I got threaded rod instead - a tad cheaper. Will weld n smooth "bolt head" and put a little sleeve in the middle so it looks like a bolt where the chain is.
Chain was $1.49/' and just like the mil ones; 2/0 style, I think rated at 500lbs??
Thanks again for your help.
123Mack - the PS magazine shows 7 piece chocks, however if the width is 8 1/2" that would make sence as that is what 5 pieces of "2 by" add up to (ea nom 1.75"). The one I photo'd was 5 piece and had a NSN on it. So I'm guessing that the PS magazine ones are "similar" but for trailers maybe...measurements for the wood chock on PS magazine:
width- 8.5 inches
length along ground side: 10.5 inches
length along tire contact side: 8 inches
bolts: 5/16" dia
bevel ground contact edges a per dwg in PS mag. This helps prevent the edge fron breaking off.
These measurements are nominal, as the wood has shrunk since maufacturing.
