using shims/epoxy to mount scope base

[danny1444]

i've heard of guys using shims to take up the gap when installing scope bases, but what about epoxies, what type do you guys use?
will epoxy from crappy tire be sufficient?

Use the epoxy steel. Comes in a two tube syringe. That will bed your bases and actions, just fine. Just remember to use a release agent if you ever want to take the stuff apart.

I used jb weld to do my old parker hale sporter 303 with side mount it worked great

thanks for the replies. here is what a local smith told me:
we use steel shims that are made by leupold. they are .012".

so when i got home i measured the gap at the rear of my scope base. it was .012" in one spot and went down to as low as .009".

so you can see how using a .012" shim would cause a problem by bending the scope base upward slightly. i feel that using an epoxy is the best solution because you do not need to measure the gap at all 4 corners.

i will be using pam spray as the release agent as well

I also use JB weld and I guess it works OK, don't really have anything to compare it to and with the gear I have I would expect not to have to use it anyway. Whether or not its required is beyond me but I used it anyway.

There was a topic about this on 24hr campfire...sounded like guys there use JB Weld to bed their mounts. This is what they had to say...

Clean all parts up with brake clean including the screw holes on the receiver. Put a thin layer of JB Weld on the bases and on the screws, then install. Use a Q-tip with rubbing alcohol on it to clean up any JB Weld that comes out along the edges as you tighten the bases down.

Use heat to remove if ever needed.

well guys, here are pictures of the finished project. i found it to be pretty easy , and all for the cost of a tube of epoxy and a spray can of pam. i used steel epoxy as mysticplayer suggested and it worked great, thanks for the advice!
i used an exacto blade to trim off the excess epoxy after it cured. if you look closely at the pictures you can see what im talking about, lucky for me the color is a near match to the reciever and scope base. (check out the last picture, the epoxied portion is on the RH side, you can barely tell that there is a color difference)
to satisfy my curiosity i measured under the forward part of the scope base with a feeler gauge and the .002" would not fit underneath, so this worked out alot better than the shimming method that was reccomended to me by a local smith.

Nice job.
