The holes are reamed to .251". Greg, Rich posted this earlier in the thread. No idea what the .040 bushings he had were but would this much play allow expansion and cracking? We will find out, I'm sending Rambler a bushing that I measured at exactly .250" to try.

How many people are using .030"s? I have a new tungsten .030 but it is going in a new build, so I dont have any shots on it yet. considering ordering a couple of the old .030's cause they seem to be trouble free and last plenty long for me...

Greg don't change the fit of your bushings when they have worked fine for longer than some recall. This is isolated and the way the plug have been was working great for a long time. We will either burn through the bad material or something will surface.

Hey guys, First I want to say that I am not trying to bash Greg or anyone else on this board.I'm having an obvious problem and am trying to figure it out with the help of all of you.That being said,I want to thank each and everyone of you for the responses and help.We will get this figured out! OK,here is a pic of my Plug with the inside diameter of .251 Here is the brand new never used .030 bushing originally from greg when he modified my plug,with the outside diameter of .2475 Here is the 1st. .040 bushing I bought from Luke that has the 7 shots on it.This one is the cracked one and it measures .2495 but possibly could be smaller because of the splits Here is the 2nd. .040 replacement bushing that Luke and Greg had sent me with 9 shots on it.This is the split in half bushing so I measured it the best I could @ .2485 With me taking the gun apart to clean after the 7 and then 9 shots is a little excessive,there is a good possibility these bushings actually only lasted 1 shot apiece??

Rich, I don't think anyone here is doubting you. Personally I'm glad you posted so we can figure out what's going on. I'm still leaning towards QC of the rod and luck of the draw, but maybe as brittle as these bushings are yours were just enough undersized to allow expansion and subsequent splitting? I'm sure Greg will get to the bottom of it.

Rlp10ml, we can do 1 of 2 things. I can replace your .030" bushing with a larger diameter one or you can try shooting it with it seated in loctite bearing lock to experiment for me. Maybe the .030" wouldn't break anyway. I will send you a .040" bushing that is at least .250" diameter to do the same with. I don't know your gun situation so you may not be set-up to shoot the .030" PM me your address, I'm not sure I still have it.

I just measured a spare .030 bushing and I got .2506 and .2507 on two different calipers... edited I will make sure before posting for no confusion

No way your bushings are that large in diameter if they came from me. They might be .2506and .2507, or your calipers are way off. I am positive the hole is very close to .251, a .256" bushing has no chance of going in. Ok, I see you edited your .256/.257 to .2506/.2507. Does make a difference.

I found 2 of the old bushings, they are already promised to 2 members that had PM'ed me. Luke has asked for a small batch of them. I will look into having some made ASAP. Those wanting some might post how many and what sizes to give me an idea of how many we need to start. I had these bushings made by a supplier, the more I order to a point the cheaper they are per piece. This supplier took 4-6 weeks though. My brother will look into material to make them also.

Greg......I do think that the diameter may be playing a part in the problem.I'd rather try a larger diameter bushing than using the Loctite and a smaller bushing.Thankyou,I sent you a PM

Have you evaluated the EDM Process to see if there are micro cracks into the base metal that might be contributing to the splitting issue. The part needs to be metallurgically evaluated to determine (cut, mounted, and polished).

What size socket does it take to get the plug out of the barrel? Mine has a loose fit but has never been fired. I will take it out and measure the plug and bushing and see how it compares to the ones that split that were posted on here. I plan on shooting it next week a bunch and will see if I have any problems.

I have a report of a .250x.040 bushing splitting. So maybe it isn't size but bad batch of material?

It has been discussed to lock tight the bushings in place due to really not wearing out. What does anybody think about JB Weld in place and do away with the lock ring. Will it hold up?

I'm going to use Loctite ® 609™ Retaining Compound with the retaining ring. I'm hoping with a bushing at .250 and a bushing hole at .251 the compound will fill any void that may allow undo expansion and hold the bushing in place for good.
This is what Jeff Hankins and fishhawk advised. We shall see.

Press fit bushing can and have been blown out the barrel. I got lucky and didn't ruin the barrel when one came out of a plug. Whatever locker that was used on that plug did not keep it in place. Personally I will not use one that does not have some type of locking device.

I'd have to a agree I tried press in bushings 5 yrs. or so ago and ruined a good barrel just the primer spit the bushing out.

Who drilled your breech plug? And did you zero your calipers?

Post by edge on Nov 2, 2014 8:37:01 GMT -5
jsthntn247, if you have loctite just put a drop on it and put the bushing back in and screw down the lock set screw. Then, VERY IMPORTANT, make sure no loctite got in the vent hole in the bushing! If you can't see through the hole then put the BP up to your mouth and blow real hard, and check for light again. DO NOT let any loctite dry in the hole or you will need to drill it out! edge. PS don't be tempted to stick anything into the hole to clear it or it may get loctited in

Is that a home made plug and bushing?
.002", is pretty loose.
