As long as you have the correct fill adapter you will be able to use a hand pump, but it's quite a job from empty. And if itsthreaded you will be able to put a silencer on it.

Sounds good Pedro. Have you seen the pellet seater/loader tool? Kind of like a retractable pencil mechanism that pushes the pellet into the breech.

Thanks Wingman, that makes sense once you think about it. I got the bushes out of the FAC hammer, so the new one is running smooth too. Will turn the the reg down tomorrow.

While you're there, would this fit into the bullpup stock you made?

Now i have had a chance to play with the F40, a bit, I find it a nice gun to hold, at the shoulder, it seems to be more acurate than i am, i find the scope that it came with reasonable, would probably suit anyone wanting it for small game hunting.
 The f40 would be a good rifle for a youth starting out at shooting, cocking he under lever takes a little effort, but is not strenuious.
 The only down side for me is loading the Pellet into the tap, my big sausage fingers do find it a little difficult with the small 0.177 pellet, the scope is not an issue when loading, I hve thought about making a tool to assist in loading, but that is about as far as I have got, though if any one has access to a 3D printer, I'm sure a prototype could be easily made.

Dont add tension to the valve spring, that spring is only there to keep the valve shut when the cylinder is totally empty, it wont do anything to your dwell time. The pressure in your plenum and the weight of your hammer and hammer spring is what controls your dwell time and in turn the velocity.
Just drop the reg pressure down to 80 bar and test again.. you can then fine tune your velocity on the reg by moving the set screw 2 bar at a time.

Probably could be filled with a pump but have never tried (Iíve only used a dive tank), yes stock is full wood. I have made a suppressor but really donít know how effective it is.

Wow, yea, ok. Once I get through all the attention I have updates. Of course no one has ever installed a reg into an S510, so this will be fairly ground breaking.

So I fitted the reg, the new lighter hammer spring and the new hammer. I weighed the hammers and interestingly the longer, new one was 5 gm lighter. So i figured that the length would give me shorter lock time. After cutting the valve pot, I put it all back together again.
Now I had turned the reg down a tad to about 90 bar so I was interested to see the results. I filled up the tank to about 115 bar and was very pleased not to have any leaks. Then started shooting a string. High 829 fps, low 819 over 18 shots, then started dropping as it came of the reg, no spike. The gun sounds more economic when firing, with not such a blast of air on each shot. I'm pretty happy with it at this stage as I'm sure a 200bar fill will yield a greater count.
It's still running a bit faster than what I want, so I plan to pack out the valve spring a touch. My target is 750 fps with 8.4 grain  pellets. I have a washer that just about fits, but I will have to remove approx .4 mm off the diameter for it to fit into the pot under the spring.
The Hammer has a type of collet in it so it glides on the rail. Unfortunately I can't take them out of the old to put in the new, so even though the new hammer works ok, I'm sure it's just not as smooth or repeatable as it should be.

Well I had some time tonight. First I shot a string, since this gun has a power adjuster I set it at approx the power i'm after. This would be around 11 ft/pd. I filled to 200 bar and ended up shooting 40 shots that took me down 50 bar, with a steady decline in fps from 778 to 698 in those 40 shots. on average it dropped 2 fps per shot. I didn't fill any higher as I generally don't have much more pressure available unless I top up with the hand pump.
Next thing was to pull the gun apart, after de gassing. Once apart I measured where I need to drill the tank,  :o and where to cut the brass firing pot.
The inside of the tank was quite dirty and a bit too rough in my opinion for the reg to seal against, so once I drilled the hole I took to it with 800 grit. This got rid of any sharp edged from drilling, and it smoothed the area needed for sealing.
At this stage I was getting cold with the pending frost tonight, and thought I'd leave it till tomorrow, so I bagged up everything, left the garage and went into enjoy the fire.

The new hammer spring is softer, but the spare hammer I got will fit, but it's longer and feels heavier, so I don't think it will help me unfortunately, as I would say it's made for an FAC model. The picture shows the one one out of the gun closest, and new one at the back.

My chrony is an old one, and last time I set it up took ages to get the light right. I got two of those led lamps from super cheap and they work perfectly.
