    I tried a search on this with no luck. Anyway, until now, I've been swapping around my NF base on my Senderos, just screwing them down. I have a couple of heavy duty EGW one piece bases coming in and I would like to make a more permanent mount to the receiver. I was planning on using Loctite Epoxy to get them well bedded to the Receiver. Does anyone recommend anything else?

    Thanks,

    Mark

    Mark - I scuff the bottoms of my one or two piece bases with the coarse drum on my cordless dremel. Using Mother's carnuba car wax as a release agent, I apply one thin coat to the receiver, a touch into the threads, and coat the threads of the base screws.

    JB or Devcon works rather well. Leave a 1/8" gap (no bedding compound) around the screw holes on the base(s), helps to prevent the bedding compound from migrating to the screws/action holes.

    acloco put it quite well.

    I make sure that there is releasing agent in the screw holes, on top of the action and all around the sides just in case. I dont mind when a little bit squezes out of the bottom. With JB weld you can take it off when it is set up (6-8 hours) yet not 100% cured and it is soft enough that it can be cut along the edge of the base.

    Thanks for the replies guys. JB sounds like a plan. I have a product called Snow Seal for boots. Do you think that will be a good enough release agent? I'm also wondering about the screws. Shouldn't they be loctited? Maybe after set up I can pull them one at a time and reset with loctite? Thoughts?

    Mark,

    I have used Snowseal for its real purpose but not for a release agent.

    I would not experiment unless someone chimes in that they have done so successfully.

    Kiwi Nuetral shoe polish supposedly does work and is easy to find and inexpensive.

    MR,

    Johnson Paste I have used a bunch and won't let you down.
    Kiwi "shoe polish" I have never used but did buy one to test it. I know many folks use it and I have read many great reports.
    J-B Weld as also mentioned above will work very good.

    I don't scuff the bottoms of my bases.

    I make sure all surfaces are clean including the bolts and all treads.
    using kiwi or whatever, apply to all surfaces, base, and areas where base goes and... just put on all top of action. Buff it a bit, with paper towel making sure is even all over. Kiwi and Johnson Paste even when you don't see it it'll be protecting you after buffing, just don't over do it.
    Using modeling clay build a dam around your working area leaving a bit of room to work. I use cotton swabs to clean the excess and also do not forget to check the inside of the action just in case you got some epoxy there.

    I never separate the base from the action. At about 10 hours I tight a bit the screws I left loose to prevent stress, when cured, I take one screw at a time and use red finger nail paint that wives use, put it on each screw and do a finger tight, one at a time until your finished. If you have a torque wrench torque them all to specified inch/pounds.

    Not only will it prevent stress on the action and or the base, but it acts like a suction cup. It'll be going no where. If you ever need to get rid of the rifle and you want to keep the base it will come off with some little tapping after removing the screws. Is not permanent but it's strong.

    My 300 Rum has this job done to it, it goes every where and no change of zero. Works great. My 338 Edge also has been done to it.

    These instructions came with my farrel 20 moa base for LA Remington.

    OK guys, I think I'll be going with the Kiwiw neutral polish.

    Eaglet, thanks a bunch for the very detailed explanation. This sounds as intense as doing a bedding job and here I though I would just be slapping some epoxy on the base and screwing it down. Glad I asked the question first.

    Thanks again,

    Mark

    Correct me if I am wrong, but I was told to actually bond the base to the receiver with JB Weld with no release agent to add stability.

    Thoughts on this?

    Thanks.

    It only sounds like that! :D You'll be impressed how easy it really is.
    If you use finger nail paint, don't forget to shake the life out of it. :)
    Let us know how it went!
