Using a RCBS sizer, a Midway brand heater using Jakes Ceresin scarlet bullet lube. Package says lube needs to be heated to 120F. I didn't test the heat with a thermometer but got it warm enough to where it flowed out thin enough to fill the grooves but not so hot it that the lube thinned out and caused problems with extracting I mentioned in yesterday's post.
The problem now is with what I believe is called the piston. The entire piston rotates along with the threaded rod and does not want to go down and push the lube. It got progressively worse. Last night I just tweaked the rod slightly and bumped a little lube into the grooves. Today the more I used it, the more I had to move it. Finally the piston was not moving down at all. Assuming the problem was likely O-rings I ran to the hardware store and got another pair. The O-rings didn't help, so back to the hardware store I got the next size up. Thought I licked the problem as the over size O-rings really fit snug but after moving the piston down an inch or so the piston started rotating again and wouldn't go down unless I pressed a screw driver on top of the piston and rotated the rod. It finally got to the point I couldn't press the screw driver down hard enough on top of the piston and it continued to rotate with the threaded rod. Turning it backwards, not a problem the piston doesn't rotate and comes right up. I tried it again with both the original O-rings, the first new replacements and back to the over sized and just can't get the piston not to rotate when threaded downward. Believing I might have a burr on the rod, I used a torch, melted out all the lube and after it cooled the piston moved up and down without any problems as long as the reservoir was empty.
Thanks again in advance for any suggestions as this problem really has me stymied.
