frank's most excellent post on upgrading his a-frame to hold 4 golf car batteries and the other paint and such that he did at the same time reminded me of a problem.
In his last pic, he shows adding an automatic change-over fitting to the regulator assembly, plus he mentioned that his pigtails were looking a little poorly so he is going to replace them, too.
My pigtails are only a couple of years old, and they are all cracked all along the length of the hose.
What occurs to me is that the relative short length of hose is expected to make two opposing 90 degree bends on fairly small radius and that is contributing to the cracking problem. So, it occurs to me that if I could put a 90 degree brass elbow on the regulator, then the hose would make a single 180 degree bend, but on a much larger radius and hopefully slow down or even eliminate the cracking.
I borrowed frank's photo and circled where the elbow would be, and (crudely) drew in the new position of the pigtail hose.
I have already tried one welding supply house and they don't have the right elbows. If any of you happen to locate a supply of the correct elbow, please let me know
