Thanks, gentlemen.
Got around to bedding the scope base today.
Had most of the stuff on hand. Just had to pick up the JB Weld and the wax stick thingy that I decided to use as a release agent.
After degreasing the top of the receiver and the bottom of the scope mount with some of the wife's acetone, I used the wax stick to coat the top of the receiver so the mount wouldn't get stuck.
I coated the screws as well so that they would release.
Since I'm only filling a gap of .005" or less, a thin coat was all that was used.
It still oozed out quite a bit.
Cleaned it up with a little acetone using some q-tips and blue shop towels.
I torqued the front screw down but the other three were just run in until they barely touched so as not do induce any stress on the mount. I will probably let it sit like this throughout the week and next Friday I will take it apart, do some final cleaning, and install it and torque it down with some loc-tite on the fasteners.
By torquing the front screw down and not the others you will actually cause it to twist and make a larger gap. Just torque them all down to where you want it to let it harden. I would think if you let it cure the way you have it now and then tighten it down you'll crack the bedding base.
I'm going to politely disagree with you. But I do appreciate the advice.Originally Posted by Spdu4ia
Doesn't do any good to bed the base if you torque all the screws down and squeeze all the bedding compound out .
The idea behind bedding the base is you tighten whatever end of the base fits best to the receiver, front or rear doesn't matter . Then just barely snug that end down but not torque it because you want the bedding compound to fill the imperfections . The other end just run the screws in to contact and thats it . Let it all set up and mount as normal .
If you torque both ends you just put the bend in the middle of the base like if you didn't bed it at all .
Thanks. I'm not very good at explaining things but that's pretty much exactly what I did.
When I test fit the mount the front laid flat on the receiver. Couldn't see any daylight or get a .0015" feels gauge anywhere under it. But the rear of the mount was sticking up in the rear. Mostly on the left side of the mount. By just torquing it down I would induce a twist and possibly a slight bow in the base.
I figured since it was only going to cost me about $6 and less than an hours worth of my time it was no big deal for me to make it about as right as I could.
after the bedding, I'm interested in seeing how 'true' the base will be with the action.
Just doing what I can to stay on this side of the dirt.
Seems to me that if there was a gap while torqued, even if you torqued them to spec after bedding it's still going to fill in the gap. I thought anyway.
He'll I don't know!
Won't change a thing unless the base screw holes are reworked on a mill to the centerline of the bore . Thats why they oversize the screws not because there stronger .
Bedding the base is to take up the tolerance stacking between the base and the receiver and make sure it runs flat and both rings are on the same plane and not bending the scope tube .
C Ward is going to be my new best friend. He seems to be the only one who understands what I'm doing and why I'm doing it.
