The gas cylinder has a ledge on the back end, it is flat on top, this protrudes into the FB ferrule, metal cap on the end... What we want is to make certain that this ledge does not touch the ferrule or any thing else..

When you trial fit the GC with the FHG on, check to see if there is clearance on both sidesof the ledge, you may have to rotate the FHG, which has the tenon reduced to allow rotation to get the ledge centered on the ferrule.. NO tension to center.

If the fit is too close, less than .020" on both sides, the sides of the ledges can be filed at an angle to clear. if things are still too close, file the metal and wood inside the ferrule even more. The ledge MUST not contact the ferrule or wood...

At the same time you are doing this, check to see how much clearance there is from the end of the cyl. to the front of the FHG ferrule.. This is a "BIGGIE," there should be at least .025" clearance. Close but not touching will not to it.. If more clearance is needed the tenon on the front of the HG has to be set back. It is this setting back, by filing off wood, where things get sticky. Of course the ferrule has been removed to re=work the tenon, when satisfied remember what was said about not getting too much epoxy into the ferrule or on the end of the tenon..Too much and you will have to repeat the mod. over..

It would be nice to know by post how many are folowing all this.. Art

With your OK, I'd like to copy all that you post on the M1 upgrades, so that I can study all before I jump with both feet and maybe screwup??

Very clear. I feel confident that we are on the same page and I can do this.

I'm still at the building confidence stage.....
When someone does the improvements please take pics!!!!

These mods would not be permitted in John C. Garand competition, correct?
These are more for personal satisfaction accuracy improvements?

Thank you Art, looking forward to the next installment.

I don't think so... Art

Here are some pics. Shows HG tenon clearance and clearances of op rod and GC. Instead of further filing on FHG tenon for GC clearance I backed off gas lock and sucked it up with the plug. Hope port alignment is OK. Paper thickness is typewriter paper folded over twice, so 4 sheets per side
I think I'm ready for epoxy. I have Devcon steel putty. Hope thats good. This is my 2nd attempt at pics.
Forgot to add that all i have for release agent are kid's crayons (not my kids). I hope that type of wax will work.
For anyone contemplating the filing of the GC ledge: It was fast and easy by hand with a coarse file.

Thank you for the pictures, they'er a big help. Like your idea of the paper shim, the drawback is paper shims have zero give, so it has to be perfect.. Perfect is hard to come by, I use a simillar method with molding clay, the clay can be compressed to allow good alignment.. I'll cover that I my next part,,, if not remind me please... Art

 

[oneshy1]

I'm using the shims to center the rod when I epoxy the tenon. Yes, it'll have to be perfect. I don't have a dremel or rat tail to file inside the HG but I may have to, eventually.
The paper was just to make sure that it wasn't rubbing anywhere.

Well, I'm following the threads but foggy on what all is being explained - however that is me not Art. I sometimes read and re-read stuff a few times before my internal light switch clicks on. The pics have helped.
