Here are the heater tubes I bent with the 3D printed die posted earlier.
Adding Vintage Air A/C in my 61 Impala. Since the heater core is now part of the underdash unit, their solution was to eliminate the heater box in the engine compartment and replace it with a really crappy plastic flat block-off plate with even uglier grommets for the heat and air lines to get inside. and then to bolt the new electric heater control valve to the inner fender. Didn't like that at all. So bent up these lines to use the original heater core cover, hide the new valve inside (there is all kinds of room because the heater core is no longer taking up that space). That cover is free to be taken on and off with no parts attached to it, so service should be covered. Well, except that the heater core is sealed into the glued together VA underdash unit. so replacement means taking out the entire unit from under the dash anyway.

Cut some metric threads with my imperial Hardinge lathe.
needed a -6 AN to M12x1.75. That arrangement with 1.75 thread is hard to find (1.5 thread is everywhere). Found one at Amazon for $10 and $10 shipping. No thanx. I almost gave in and was gonna use a brass fitting with hose barb. Then I remembered that about 10 years ago a bought a set of custom gears for the Hardinge to do metric, and have never used them. I had a fitting with M16 threads I whittled down and re-threaded...presto changeo.
   
By the way...its for an LS engine pre-luber. Cant just use a drill down the distributor hole to spin the oil pump like an old small or big block chevy. So, I had a "spare" big block chevy oil pump on the shelf, and a bucket. But like everything with me, it got way complicated and CNC is now involved in making other parts too. I'll share when I get it done.
