Our new barrel for a Caterpillar D10 dozer blade lift cylinder is finished! In this part 3 and final video of making the new barrel we show the process of making the new end before fitting and welding it to the new barrel. We start with a solid piece of 4140 round bar and do some heavy turning in the lathe before drilling and boring out the ID. We also machine an internal radius on the inside of the new end. Then it’s over to the milling machine where we drill and tap a couple of bolt holes before turning the head of the mill 24° degrees to drill and bore the grease port. The work on the milling machine is completed with face cutting the step to give clearance for the drop valve. We then fit and weld on the new end to the barrel before giving it some final touches before a new coat of paint to complete the new barrel! MISSED PART 1 & 2?
