I've read a few articles on bedding , some say to relieve the front and sides of the lug area when doing the clean up. others don't. I normally tape the sides and bottom of the lug for clearance but have never relieved the front.
Any thoughts ?
 
I do sides, bottom and front just to make the action easier to remove for a yearly inspection and cleaning, if their are other advantages or disadvantages I'm not aware of them. Just my 2 cents
 
i do the three side as well. i used to not tape the frt of the lug but made removal very difficult. accuracy doesn't seem to suffer as the recoil forces try to drive the lug backwards were its fully supported.

Me too..
There has been no demonstrated accuracy advantage one way or the other. But I much prefer the easier method and it eliminates a potential problem of the lug not fully seating.
 
I usually put 2 layers of masking tape of the front and bottom of the lug before applying release agent.

I want the back and sides tight...... So I never relieve them after the bedding cures.... I can see the point of doing it if you plan on frequent removal of the barrelled action.

I've always believed that "tight is right"..... Any extra play will effect group sizes..... IMHO.

But guntech knows his schiltz...... So I defer.

This is my main concern with the tight lug fit. although I've never had trouble there is the chance it could hang up and cause stress. I just hated the thought of taking the grinder to a good bedding job but when you thing about it the only important surface is the back side of the lug that takes the impact, the rest of the bedding should hold the action true.
 
There are also rotational forces at play....

Think about the torque that starts the projectile spinning, newtons law states for every action there is an equal and opposite re-action. If the bullet spins there will be rotational forces imparted to the barrelled action. If there is play in the lug area, it will twist just a hair as well........
 
Why does everyone (almost) use masking tape? Epoxy doesn't stick to plastic tape and give a better looking job. I do a lot of comp guns and I don't want the customer fighting to get it apart and back together if he has a problem on the range or on a hunt for that matter. I give clearance on the square sides except for a bit close to the bottom. A well designed action would have draft on the sides and I have a friend that does that to Pandas, take a hint Kelbly! The lugs I make also have draft and all this means it can be bedded solid and still come apart easily. A battle to disassemble is not needed or wanted on my guns!
 
Electrical tape works. It is usually PVC and epoxy may tend to stick a bit but a light coat of release fixes that. The problem with masking tape is when to try to pull it off it rips into many pieces and is a bugger to get cleanly off.
 
I use higher quality masking tape... probably $6 + a roll... a lot of cheap crap is on the market that is worthless for anything.
 
And not to hyjack the thread, but why flip the rifle upside down while the bedding cures?

I don't cure it upside down, no reason to.

In a word .. bubbles.
Inverting for cure will draw any gas bubbles present up and away from the finished bedding surface you can see.

It feels kind'a strange so it does, this first time not agreeing 100% with something that Ian has stated. I'm just another amateur punter, but that man, he REALLY knows his chit.
Whatever, no biggy ... inverted works for me. ... :D

To the topic:
I tape bottom, sides and front of the lug.
Have shaved off epoxy when re-installing if there is no clearance built in. That shaving, or any other foreign matter that finds it's way down the hole, can cause the receiver's bottom surface to not bear fully without a few thou. of clearance under the lug..
