"In the world of spuds today"

this input should speed up fill time and put less strain on the motor.

As strange as it sounds, this actualy puts more strain on the motor. If you have access to a Kill-A-Watt power meter, you can see this loading directly. AC guys measure compressor power consumption as an indication of system performance.

Raising the amount of gas you compress, increases the burdon on the motor. It has to do with being a gas, not a liquid. Higher pressure is more stuff to compress. That takes more power even though the boost in pressure is less. It's like carying a lunch bag up two flights of stairs vs carying a refrigerator up one flight of stairs. The bigger heavier object is more work.

Higher pressure air is bigger/heavier to move unlike higher pressure liquids that remain the same volume.

oh right i realize that it would be harder. and it doesnt sound strange after someone explains it . also i just now remembered that its most likely not a pisotn compressor so there will be no extra pressure pushing the piston up. so it will be harder overall lol. well at least it will pump faster! and i can get a meter so i just might have to check and see just how much harder it pumps

After more than a year of silence...the co-ax speaks again.

Had an hour to "git 'er done", and made of it what I could.

Hope you enjoy.

She certainly "speaks" with authority any chrony results for those slugs, or at least penetration depth in the maple?

[Gippeto]

~1.5" to the rear of the slug in the maple.(Roughly 2.7" total penetration) Range was 20 yards.

[velocity3x]

Excellent power and penetration! Well done.

Can I get away with a 3" access cap to my metered combustion? I only need it for occasional cleaning of backfire and maybe venting. Is it worth the extra £10 to get a 4" cap?

[Ragnarok]

I wasn't originally planning to show you this until it was done, but my willpower is a little lacking.



Before anyone asks, it's not HEAL 2. It's just HEAL with different bits attached to it.

Looking good Rag, what's the pilot valve gonna be?

[Ragnarok]

Well, the main pilot is the QEV you can see in the picture. The pilot's pilot is still going to be the same sleeve/slide valve from when I first made it three years ago. (I'm surprised it's that long ago, but I first made it in May 2007).

As and when I've actually cut space for it in the stock, that is.

[Gun Freak]

That's gonna be a little awkward to trigger in the stock don't you think? I was thinking more of a blowgun modded to fit in the slot where the trigger would go...

Finally, something "new" Tactical black eventually or are you going for the "steampunk" look?

[Ragnarok]

That's gonna be a little awkward to trigger in the stock don't you think?

No, I don't think. I just wing it and hope nothing catches fire.

More sensibly, there is a rather useful machine called a router which can quite easily do that. Between that and a Dremel, it's not the hardest job. Theoretically, it's doable just with hand tools.

Finally, something "new"

For certain values of new.

However, I've done some rebuild work on the valve, safety and breech loader, which should improve flow. I've also tweaked the pump a little, so I should be able to push pressures to 25 bar.

I've been accumulating targets and projectiles for a while now, so there should be a new video, although when it is will depend on whether I finish the build before heading away on this year's narrowboat cruise.

Tactical black eventually or are you going for the "steampunk" look?

I'm planning on going steampunk. I can't paint things like the barrel anyway (the breech loader would scrape it off), so there's going to be some bare copper whatever I do.

Also, it doesn't need to look threatening (painting it black would probably do that) and in many ways, it's better if it doesn't.

Can i ask how you managed to epoxy (I'm guessing) the Dovetails on to what looks like 15mm copper? I always have big trouble when trying to mount my scope.

Finally does anyone have any other idea how i could mount the scope?

The best idea I've seen so far in terms of effectiveness while using a cheap off-the-shelf products wasthis one by jook13
