I have considered making my own, but it could turn into a can of worms. Often there is more R&D in "simple" projects than meets the eye. Too, the TTracks apparently use a Manganese alloy grade 80 chain, which is pretty spendy. TT claims that their 7/16 M alloy chains are stronger/last longer than the 1/2" they used to use (grade 70, I believe). Buying in small quantities may be prohibitively expensive. There is also the issue of which rod to run, whether or not to heat treat or anneal the welded chain links, etc. For the price, I think I'll spend my time moving someone's dirt.... I hope to hear from someone who has run these puppies. That would be nice (and not the owner's bro, either....) Otherwise, I don't see how a person could go wrong w/ Grousers, McClaren's, Loegering, etc.
