Throat view. Original Flex valve versus a JSAR SS. This is the large port version. Yes, I know it is going to blast open so easy, that there will be much hammer spring weakening needed. I will also close down the jet and/or put the stronger return spring in if needed. We will see. I also need to measure the hammer weight as a reference point.
I will stop here for today as all the parts are now clean.

I'm very surprised to see the WAR valve have the same type of lip vale seal that causes so many problems in the Rainstorm at higher powers. I like the new one you show much much better!
A shame you had to had t destroy the bottle. I could have had it checked, and possibly repaired and tested.
If you have any FP-10 around, put a full wax job on the barrel, and then a very light coat of the FP-10 on it. No move rusty spots. Flitz makes a good wax just for gun barrels. However any good paste wax without polishing it can work.

Thanks for the wax tip Michael. I ordered some of that to try.

Old vs new hammer.
I decided to go with a MDS hammer. I am aware that WAR tried a MDS one for a while, but it would drag sometimes, so they went back to a metal one, though lighter than this original metal one as the newer balanced valves don't need such a heavy hammer and are more efficient with a lighter one. Note that this MDS hammer is not a WAR one though, and I have as well ball honed the cylinder to an ultra smooth finish. I want to see if I can use this through the seasons without any drag issues.
Another note here is that I have loktited the striker in this position to make the hammer as long as a WAR one. This is necessary, as the Timney trigger is not like a Marauder one where the hammer can push the sear back down even if it slides fully in front of it. The Timney one would have to have the trigger held to cock it and allow the hammer back over the top. By keeping my hammer long enough, the Timney trigger will not get hung, as even with the hammer fully forward, its body is still over the sear holding it down.
Total weight as shown plus the hammer retention bolt and and aluminum spacer washer in the next post is 52.2 grams.

Hammer springs!
Original WAR one on the left.
The middle one could be used, but doesn't quite allow free flight.
The right one seems about right.
We will see tonight.

Hammer cap screws. My new one is in the left. I had made up several of these when making a Marauder with custom riser. It is a little longer than the war setup, but needs to be because it goes through the MDS before hitting brass underneath.

I put the rifle together last night but stopped as I found the MDS hammer sliding a bit too snug after I put its retaining cap screw in. The compression against the MDS shell must deform it ever so slightly as it was more free without the bolt. I will take it back out and drill out the plastic there, so that the bolt spacer can sit directly against brass the brass core. Hopefully this is enough. Edit: This appears to be part of it, but also I honed the tube a bit more at the back. I will redo this further in. I did hone all the way to the valve, but as I didn't want to go beyond that, I obviously didn't spend enough time down in there, so just need a bit more. I am using a 400 grit hone, so it removes very little.
I also ordered some Mr. Hollowpoint and Nielsen Specialty Ammo slugs in .30 (.303) to try. The barrel is choked for pellets, but I still want to try it.

Regarding finish
There are a few scratches on aluminum that I want to fix. Can someone report how well the Birchwood Casey black aluminum repair works? They have a chemical that will either blacken or turn brown any raw aluminum. Then if that is not enough, they have a paint marker pen for final touch ups. I am open to other suggestions as well.
I have had a thought to camo it, as I like the look on the ones Bullfrog did, but for now I will touch up the black aluminum.

The B.C. alu.black works fairly well. I recently picked up a black paint pen from Fastenal It works well, but you have to use something like a q-tip shaft to blend it,as it goes on thick and would stand proud of anything it is applied to.

David,
Good job on picking on the Flex, I was very interested in it as well when it popped in the GTA classified gate. I see that is in good hands and will have a better life thanks to you. It just needs some elbow grease, a very thorough cleaning and some o-rings like a lot of used guns out there.

Michael, ok thanks. I ordered the BC aluminum repair and also their paint pen to try. I will go lightly with it and see how it goes.
Thanks Randy. I got a great price and hopefully a real keeper once I'm done. With a few scratches already under its belt, I won't have to baby it wanting to avoid that first one.
I didn't work on it any today. Maybe tomorrow.

Hammer updated.
I countersunk the MDS plastic so that the aluminum spacer could hit the brass underneath. Here it is put together with that longer aluminum spacer from my earlier post. I just needed to switch to a 3/8 cap screw instead of 1/2, so that it wouldn't protrude into the center spring cavity area.
I will still do a slight rehone on the tube, but this already slides better since the screw isn't deforming the MDS anymore.

It will help with deformation a lot! Well Done!
Man I would love to get my hand one of these. These and the AAA's are for me "The Holy Grail".

Ah Scott. I would have given it to you, but I just yesterday promised it to someone with a stock Marauder valve. Seeing as how they let me hunt their lease many times at no charge, it's the least I can do.
Oh, and thanks for the inbox tip. I didn't even realize it was full.

Ok, the Flex is going together now. I finished the slight rehoning and cleaned it all out again (honing leaves a huge mess of black gunk in the tube and all orifices). Then I gave the honed area a wipe down with Balistol. The powerplant is all in and ready. The hammer slides very smoothly now. I even did a test with just the tube and hammer where I put the tube in the deep freeze (-5 F) and after 20 minutes took the warm hammer from my pocket and did a slide test with the tube. It was still silky smooth, so I don't see how I will ever have any drag issues unless MDS somehow starts to expand a lot more over 98 degrees. I guess I could have heated the hammer also, but I was satisfied already.
