Hey John, it's been almost long enough I almost forgot about that load of nice round boulders you "inherited". ;) Now what's with that major chain from that pole to the little boat?
Oh yeah, tracks looking good, what’s the min rad?
HJ,
That’s a log choke I found on the Columbia River bank years ago. There is a big cast ring on one end and a cast “T” shape doohickey on the other. It weighs about 50 lbs. It’s to keep that dingy from floating away!
Min Dia on the inner curve is 15’.
Outer curve is ??’ made with the Train-Li bender. So, prolly 15.5 or 16.
