have been working on a jib boom again in the shop, in between jobs. I needed a left handed thread pipe adaptor for monday Im pumping cement 800′ down a well the plans call for unthreading and leaving the bottom pipe after pumping the bottom 200′ full of cement do to water chemistry issues. so whipped this out this afternoon 6 thread per inch acme
the jib boom is going to be very handy for loading the lathe and flipping smaller stuff over going for 1/2 ton capacity with 17′ of reach
and there is a 130 x 60mm roller thrust bearing in the bottom housing to help cary the load the bronze is just to keep it straight
