    Freeing screws in new brass NOE

    Hi folks,
    Picked up a new brass RG2 mold from Al, Did a heat cycle right away and then when I went to free up the handle screws they were too tight. I’ve got Kroil on everything and I’m going to pick up a socket allen wrench to get more torque on it, but obviously I can’t afford to strip or bugger these things. Whaddya think? Don’t know if they were already this way or if I really set them in the heat cycle. Never had this problem, also only my second brass mold.

    might try another heat cycle and try loosening them while the mold is hot.

    Cut off a cheap standard allen wrench leaving as long as possible. Clamp and blocks mould in a padded vise, you want it very solid and not moving around. Insert the length of allen wrench and lightly tap on it with a small ball peen hammer( 4oz - 8oz). If you have a small box end wrench or tap handle on the Allen apply pressure while tapping. A standard tap handle is desired here as it can be slide down the Allen close to the head and the allen sticking thru to tap on. The vibrations and torque may break it loose. A couple drops of kroil around the head of the bolt while doing this may help also. THe tapping creates a vibration and down pressure that helps free the threads up, with the kroil in there the vibrations help work it into the threads and under the head.

    Thank you, I will do as you suggest.
    All of them freed up except handle screws, I will let you know how it goes.
    It seems to me that the handle screws are slightly bigger than the RG2 bracket screws. I’ve never needed to seek out the next partial size because I’ve never had them so tight. Gonna do that today.

    You could call Al at NOE 801-377-7289.
    He usually answers the phone and is always helpful

    When they break loose work them back and forth as you remove them. On new threads there may be chips or swarf that's binding them up. Another could be dried or hardened cutting fluids. Some of our water soluble oils got pretty sticky gummy when they dried out. Work with it and use only the frce needed.

    He is a great guy. I came home to a response on my machine one day over another matter. I’m going to try the last suggestion before I call him.

    Country gent, thanks again for the excellent and thorough council. I will do it when I get home, I have zero doubt that it will work.

    Your welcome. The big thing is getting the piece held securely so it cant move. This doesn't allow the full force applied to be utilized. Then when the part slips or moves it gets marred or damaged

    And put some anit-seize grease on them so it doesn't happen again. LEE moulds do the same thing.

    The method worked perfectly. All set.
    They were definitely in there.

    Like with firearm screws, get a screwdriver that fits the screw exactly, it will limit the chance of slipping.damage.

    Great advice.

    I use a automotive Copper Anti-Seize Lubricant on any threads on a mold (or engine).

    I use the same thing but in a 1 ounce squeeze tube. Napa brand. Same tube has been on the bench for the past 10 years. Real easy to apply to sprue plate pivot and alignment pins while casting. A little goes a long way.
