Tuning FX Impact M3 modified plenum front part remedy for slow initial shots

[Seeker]

People using Impact in competition in my country also complain..........Bhaur

Bhaur, you have a great opportunity here, but the part need to be cut on CNC Mill with auto tool changer.

About a full 8 hrs of CNC programming - with some coffee brakes + you need two jigs, and these can give you roughly about 6 minutes total cutting time per piece. Translated to your local currency still makes a business case. A manual lathe is a no-no unless you do it on your own time.

It must be cheaper then the OEM part: https://www.europeairguns.com/en/fabricantes-2/fx-airguns/FX10338

I don't think it must be cheaper than the oem one. The custom one is better and more advanced. It can definitely be more expensive.

...The custom one is better and more advanced. ...

OK correcting myself

I didn't meant to calculate the $$ per piece but a dimensional consistency if you planning a 50-100 piece batch ...can really make a difference.

If you do a single piece for yourself or eventually a close friend - for a hassle free if there is no CNC available - I would separate into two pieces and handle them same way as the Valve House is locked+sealed.

At this stage I just had to do some R&D and for this purpose I think making one part on manual laith is not bad.

Yes if I had been into this business and had a lot of orders then taking the route of CNC would be economical and time saving.

Ok, you meant the production cost.

In fact with low reg pressure while using 18.13 grain pellets at around 870 fps, M3 is not consistent for around 4 shots taken first time in the morning.

Means it settles gradually after a few shots.

Seeker found a solution for it that worked for him perfectly but it worked for me partially. He used peek disc to avoid the O ring from protruding.

Hence I went back to MK1 system of O ring sealing the valve rod in the plenum.

MK1 didn't have the problem that MK2 PP and M3 have.

Very few people notice it.

But for those who notice it, it's very irritating.

Hence for more for consistency and for using various weight of pellets at various fps without much adjustment of reg pressure I understand that the new setup will work. Just like mk1 worked for all this.

Hi there. What was Seeker’s fix for the plenum valve rod oring. Where was the peek washer placed.
