Station 2 locator tab adjustment
Quote from Reloader on December 15, 2020, 2:03 amHello! I'm having a problem with the station 2 locator tab adjustment screw. It is stuck and I can't turn it. I'm afraid to put too much stink on it for fear of rounding out the Allen socket or breaking off the 5/64" driver. I have it soaking in Aerokroil penetrant now but I'm skeptical that will make a difference. Anyone have any ideas?

Quote from Reloader on December 17, 2020, 2:14 pmIf I could not get the screw loose I would remove the primer system and put it in a vise to secure it. I have a set of 1/4 inch drive hex sockets. I'd turn the air pressure regulator down to about 50 psi and attempt to loosen the screw with a pneumatic impact driver making sure you are pressing the hex drive into the screw head with a good amount of force. If you bugger the screw head, drill it out and replace it.
I don't know the coefficients of thermal expansion of the metals used so I don't know if applying heat would help. Good luck with it.

I really don't want to drill it out but after soaking in a penetrant for a few days it isn't budging. I may try smacking the wrench to see if I can loosen it up. The housing is aluminum and the screw is steel. I may try heating it up and I'll save the impact wrench for the last ditch. Thanks for the suggestion.

It didn't even take much heating. I literally spent more time getting my torch going than heating the housing up. I couldn't find one of the 3 or 4 bottles of propane I know I have so I went to the hardware store to get a new one. Then the first torch head wouldn't light so I went to torch head number 2. Finally got one going, heated it for 10-20 seconds and gave it a try and it came right out.
Thank you very much, I wouldn't have tried that without your suggestion!
