Hi,
I have my star (purchased used) set up to lube boolits and it does a good job. However, it takes a tremendous amount of pressure to compress the spring at the bottom of the unit and pump the high pressure lube. I am using Lars BAC. I have heated the lube some and still have the same issue. Lars advertises that the BAC doesn't require heat. I think it has to do with the exterior spring on the base of the unit (part of the high pressure lube pump) or the cam set up.
After lubing a bollit, the spring SLOWLY returns to it's uncompressed length. I would expect the spring to rebound much more quickly. I am wondering if there is some grease or something that is gumming up the works and preventing the spring and rod from travelling freely. Any suggestions? I will try using some Gun Scrubber cleaner in this area to see if it removes anything.
I am also going to try adjusting the horizontal bar with the two bolts near the top of the unit to deliver more lube, but don't really think that's going to fix anything. The spring in the lube reservoir is fully compressed. I like that I can lube 20-30 or more boolits without needing to increase pressure in the reservoir.
I did flush the sizer inside and out with very hot water to remove the old lube that was in it when I got it.
Also, do you lube any parts of the sizer? If you do, where do you lube and what do you lube with? The online manual doesn't mention anything about this.
Thanks!
John
