Finished bedding my LRB, just in time for Christmas!

Merry Christmas, everyone!

I've been prepping a composite stock for a while now and finally got around to bedding it last week. It required a bit of work and I had to go back after the initial bedding and do some "patch work" to fix some very small voids.

More info here:

**Update Success!!** How do I celebrate the end of the world; by bedding my LRB!

Anyway, I finished the patch work and it didn't come out as pretty as the initial bedding, but it is functional and will probably work out just fine. It looks ugly in the pics but the surface texture is smoother than it seems on the camera images. Either way, lessons learned and I'm headed out some time this week to see what kind of results I get out of it. A couple of things changed since it was last out

First, I bought a new welded unitized gas cylinder. Second, I changed the stock, third (not installed yet) will be a new NM reamed flash suppressor from Ted Brown once it gets here in the mail. This was also the first time I used Marine Tex and man, it's hard stuff! I used PC7 last time and it never cured properly and was always a little spongy.

So here's a breakdown of all the components...

LRB M14SA standard receiver
Criterion Medium weight 1:12" reproduction of the Saco-Lowell NM barrel
H&R trigger group
TRW bolt
SEI op-rod
SEI NM rear sights
Sadlak NM spring guide
SEI welded/unitized gas cylinder with melonite treatment
Carbon-graphite-kevlar stock, routed and bedded
Ferrule routed for clearance
NM reamed GI flash suppressor with NM front sight
NM welded front sling swivel

My goal was to make it into a sleeper match rifle and I think it's there. I can't wait for the accuracy results. I'm fighting the OCD in me that says to bed it again until it's perfection, but at least the foundation is laid and it will come out looking really nice next winter when I skim bed it. Bedding is getting easier and quicker with practice. I was afraid of mixing the Marine-Tex but after making 3 batches, I'm finding my routine. I put a pot on the oven with about an inch water on simmer and put the Marine-Tex can in the pot to make it easier to measure and scoop. It was a great help!

What this stock really needed was full support around the receiver legs and full support under the receiver and now it has it. I hit it with a quick coat of Krylon camo dark brown paint. I also took the opportunity to give it a good annual cleaning and lube job. She's all greased up and ready to go!





















I think all I'm missing now is a NM sling. I haven't decided on a leather or Biothane sling yet. I think the take-away for me was that when doing patch work, you have to re-route the whole thing, not just the area you want to patch, if you want it to look right. That was just a learning experience that I'll learn from next time.

But hey, there's always the original birch stock that I routed at the same time and is ready for re-bed.....

I'M A SICK MAN!!!

Tony.

Looks good to me. One of these days I will get the Cactus Comet teach me how to bed the 14s. Looking forward to the range and match reports.

Your too critical on yourself, it looks to me like a perfect job. It's the only thing I have not tried yet. I have a cracked GI stock that one of these days I will practice on if I can keep my rifles.

Thanks folks. Warren, clay and mold release (valspar 225) is your friend! You can do it!

That's a nice job TB. How did you make the clean notch in the bedding in area in front of the receiver for the recoil spring guide?

Tony,

I have been following your trials and tribulations to get that stock bedded, and especially for someone who has not had an Instructor to teach you. I applaud your persistance and am really grateful for the posts and tutorials you have written for other forum members.

Now, how do I say this without sounding like the Grinch who stole Christmas and am in no way trying to be too critical of you?

I don't doubt the bedding job you did is tighter than any wood or fiberglass stock would be, but it won't stay as tight as it should for as long as it should.

You really need to do a FULL skim glass job on that stock now that all the voids are filled, so the bedding surface looks like a mirror image of the receiver. The bedding will remain MUCH tighter for MUCH longer when you do that. Also, use the technique I've discussed about PRESSING the glass onto the receiver and stock so the glass around it beads up around where you have pressed it in. THAT's the secret to getting the mirror image surface.

PLEASE don't take this as being over critical, but if you don't know what the best bedding surface is, you will never get to that point. I'm sure with your preserverance you WILL get to that point, though. It just takes more experience at bedding and especially when you don't have an Instructor there with you when you are learning. Good job so far, you just need to improve and that will come with more experience.

Merry Christmas from Gus, who is not tryng to be the Grinch who stole Christmas. Grin.

Thanks from tonyben

Gus, I'll always appreciate any constructive criticism you give and I completely agree with everything you said. I realize my mistakes on the patch attempt now and I'm eventually going to do a full skim bed job. I'll still take it out on Thursday and see how it shoots but now I have to order a new can of Valspar and try again.

Christmas is far from ruined. :)

Tony.

Tony,

I really appreciate you took my comments as only constructive criticism and not personal criticism. For a person trying to learn this "on his own," you really have my respect. With your good attitude, desire to do good work and your preserverance, I know you get to the point you will do first class glass jobs with more experience. If we didn't live a continent apart, I would invite you to my shop to do it over under my supervison, BECAUSE of your attitude and desire to learn.

The reason I made the constructive ctricism was also for other forum members and in case they PAID a professional to do a glass job. It it turned out like that, they should NOT accept it and give it BACK to be done correctly.

Thanks from tonyben

Thanks for that Gus,

It means a lot to hear that.

I also agree that for a paying customer, it is poor work.

Tony.

Tony, you lucky dog. If Gus were to offer me the opportunity to learn how to bed the 14s under his supervision, I'll be in Virginia camping at his door with a case of malt. Well, for consumption after each session.

Gus, nice of you to make that offer to Tony. Class act.

Sorry I missed this earlier. I use a file for the spring guide slot and a dremel for the spring clearance. I also shave some off the front until the op-rod contacts the face of the receiver. If the op-rod is hitting the bedding, it will probably shatter the bedding compound.

Tony.

Gus or Tony, just a quick question on skim bedding a rifle that was done with the wire method. When skim bedding, does the wire have to be used? I've bedded a few Garands in the past using the NRA publication and just recently bedded my M1A Loaded in a GI stock using the wire method. Wished it looked as good as Tonyben's, but it's pretty close.
Thanks everyone for their great posts and pics!

Thanks from tonyben
