It's difficult to estimate the dimensions of that plug from the picture, but assuming a length of ~30mm and a tensile lap shear strength of 1KPSI for the epoxy, the joint should hold about 2.4KPSI. I would have went with more bonding area, but it should be fine at up to 10X or so.
The plug has a diameter of 25mm, and the bonding area is 25mm high.
planning on using a syringe or more complicated means of metering. You seem to be moving out of the realm of mini hybrids
Just syringe metering, cheap and reliable
It isn't clear to me where a mini hybrid turns into a normal sized one
Looks good, but what's that slot in the schrader? Won't it compromise sealing with the pump head?
It isn't a schrader, it's a dunlop valve.
I use it as it doesn't have a spring in it, and it doesn't leak air when disconnected.
Depends what's most important, low noise and massive power are competing parameters, it's difficult to have both... but not impossible
I'm going for the 20 cm chamber
Power is more important te me
I'm thinking of keep this unsurpressed until new year's eve, people don't pay very much attention to loud noises this time of year
especially not when they're my neighbours
I'm thinking of using a DWV pipe as the supressor housing, what size would be appropriate?
the barrel will be 1 meter long.
What calibre is this anyway? With those dimensions a 0.22" will easily be supersonic at 12x, I assume though you're going for something bigger and heavier?
I'm going for the largest one that fits
With a bit of luck it will be in the 16 mm range.
