Tuxing double cylinder compressor - air leaking into crankcase

You guys were right, oil level was a bit high but not by much.
When I poured new oil in few months back it was really cold so it was settling slower than I thought. I'm always careful about this things but obviously got it wrong this time.
But, this was a new oil after rebuild with maybe 10 minutes of work time and colour is worse than the old oil which I've changed after 2.5 hours of work time.

I'm using Bauer diving compressor oil so oil itself is not an issue.

Everything is still the same even after lowering the oil level. It still blows blue smoke out of the breather.
Mind you, there's not a lot of smoke and it's visible only when I point a flash light at it, under normal workshop lighting it's not visible so I may have this problem for longer than I think I do.
I have topped up my 6.8L bottle two times this week from 260-270 bar up to 300 bar without any issues.
But, there is evidently a problem and potential bigger malfunction waiting to happen.

In any case, after two cylinder rebuilds, there's no point in rebuilding them for the third time. I'll buy both new cylinders with all the parts and change them completely.

Only question is when, my spring vacation is over, little free time that I have on my hands I spend rebuilding my lathe which won't be finished any time soon. :cry:

Airgun Technologies  Vulcan 3 burrs near the crown

I managed to squeeze a few shots yesterday.
I can now say that MRD Grand's shoot better from my Vulcan than Deep's.
Tried KO .216, terrible, about 50mm (2") groups at 50m
Tried KO .217, these were great, two groups, 15mm and 20mm (really don't know inch conversion of that)

Then the weather turned around in a matter of minutes, we got strong winds, heavy rain and hail.
At least it's a start, I've fixed the barrel problem and it shoots good.

Only problem is, it will be weeks if not months when I'll have free, alone time to shoot again.

Airgun Technologies  Vulcan 3 burrs near the crown

We have few clubs (regarding airguns, firearms have many hunting "clubs" but only few shooting ranges and that for clay pigeons only)
Our airguns clubs are for 10m olympic air rifle or pistol. Whole country has two FT clubs but only on paper, no ranges, no club spaces where you could go and talk to people, nothing, we don't even organize FT competitions since we can't get more than 10 people to attend.
My country's shooting federation doesn't recognise FT as a shooting sport.
All hunting and pesting is forbidden which makes airguns less attractive to many.
My country's view to sports is very simple, if it doesn't involve a soccer ball, it doesn't exist
At least we don't have calibre and power restrictions, we just have to register air rifle to keep it legal and that's just a formality and easy to do.
But, since they are collecting and applying all the stupidest laws from all around Europe, it's just a matter of time when they'll put air rifles in the same category as firearms.

Eyeglasses or not?

Now that’s an interesting thread, I have always struggled with whether to shoot with my glasses on or off as I use separate glasses for reading and distance so have never been sure as to what to use.
Think a trip to opticians is due as these progressive lens glasses that have been mentioned look like they could solve my issue.

Tuxing double cylinder - crank screw removal

Have you found that the c-clips are loose in the piston grooves? That's typical for Yong Hengs, IME.
Haven't really checked the c clips.
They don't have to be tight in their grooves, they just need to be in the grooves enough not to fall out so the part they are holding is secured in its own place

Air Venturi  Avenge X Barrel on the Avenger?

Has anyone tried to fit an avenge x barrel to the avenger? I know they are a bit different with the dimples for the screws but it would seem to me that should be easy to fix. I'm curious because I like the idea of putting the shorter 15.7" avenge x barrel on my avenger.
Does anybody have an update to this? I'd like to try to modify a. 22 cal Avenger using a .25 cal Avenge x barrel

Looking down that brand new barrel

I'll be honest. I've been listening to some great Gospel music when I saw that heading,"Looking down that brand new barrel." Oh, yeah,brother, I never will be looking down that brand new barrel. Oh, yeah, amen.Oh, yeah,and it shoots dime-size groups. Brother, count your blessings. Maybe it is Gasalt.:D

RTI  RTI prophet l , Gage in the rear..

Yep I kind of lusted after the 22 LR barrel , But really 99.9 % of my shooting is at 50 yards and below , I played around with slugs with the Vi but Pellets have alway made a tighter group,, I got the 700cc bottle on my gun and I get a lot of shots before any refill, Tuned it to day shooting JSB 25.39 gr pellets reg set at about 150 adjusted hammer spring until it sounded good, shooting at about 900 FPS, , Really like my RTI guns VI and V2 but going to side step the Mora , and get a new Semi auto Taipan, Got to make some room and break the rule no more new rifles , Went a little pistol crazy this past year, Birthday present coming in a week or so, A hand made one off shorty 22 Tequila pistol,,, Its going to be a keeper for sure ,

Pellet Sizers available for Pre-Order

Maja from Zan informed my that you can switch calibers by buying different size plates and pin using the same base.
Yes true, bases are all the same. But for now we are not offering only plates, but that might be an option in the following weeks. First we would like to bring those to shops. We now have all parts, just few plates for .25 cal is missing, so next week we can start shipping them out.

Barra  Barra 250z. Tunes

Good💯 i got some 30 grain slugs to try. Those 31 grain aea slugs are good though they are new not pellets.
And I’m sorry I missed where you said slugs haha… honestly it shoots anything from 30-40 in my experience. 37gr is the most I would recommend.. but as a hunter I find that the gun really shines with the 30-33gr slugs going real fast.

Air loss through the barrel when installing M3 powerblock kit

After several attempts fitting my power block kit (20845) in my M3 and dumping almost a full bottle of air I gave up. I just didn’t understand. I followed the video instructions of both Matthias of ‘Airbuks’ and Ernest Rowe of ‘FX masterclass’. Neither even mentioned the Valve seat.
Then I started to search the net and ended up here.

I purchased the kit trough Huma Air here in the Netherlands. In the box was a pack list. On it number 20860, the valve seat and accompanying o-ring 19720. Only these 2 items were not in the box.

I didn’t think anything of it because the valve seat was on the valve rod and they also make you re-use the o-ring underneath the manometer. (I think FX is too cheap. Why don’t they just supply all o-rings needed I wonder, but that’s another matter)

But after finding this post I started to measure and discovered the valve seat is too small for the new valvehouse. I think it’s ludicrous that you have to find out yourselves and even more insane that they might make you purchase that part separately while it’s on the pack list of parts that make the upgrade kit.

Did you end up buying the new valve seat?
I now have to wait and see what Huma air says. I’ll have to wait for them to answer my mail request. There’s no phonenumber on their website.

The only way I can shoot for now is by fitting the old block and valvehouse.
