JSR, the epoxy man You no have hands that stick sometime.. after 5minute to intense activity?

Thanks, it's fot a french forum member, but he is afraid by the fact that the US standards are differents finally.

[Crna Legija]

no problem, this member is french and he's is quite safe.
heres another from him.

(well jsr did but he used epoxy )

Worth pointing out that he used epoxy badly when the fail occured.

Using epoxy correctly, he has been right up to 28x regularly without failure.

We will see if his use of epoxy will diminish as of next Friday

And WHY????

Hi, i made two new video yesteday, where i'm shooting 20mm diameter cylinder, and 6cm to long.

I'm limited to just over 200psi so i's not very very powerful yet...

Nice, I would wrap tape around the other end too, it will be more stable in the barrel and probably come out stronger.

I'm not sure of your backstop is adequate, especially if there is something behind that hedge that might be vulnerable to pieces of steel flying around at silly speeds

And WHY????

Because of the Sherline but *gasp*, I mixed Araldite yesterday for the first time in weeks!

You're right, but i wanted to put le center of gravity (i don't know how tell it otherwise) forward of the projectile. I'll try

Yes i'm not sure too, but it's the backstop the strongest that i have, i knew it resist at lesat one shoot but the second has already fissure the last wood piece. The next shoot will brake it, and it's dangerous for behind.

I haven't got a crap dealer in my neighborhood, but i'll try to procure me a steel plate.

Center of gravity is correct, actually. Placing the tape at the back of the projectile will help drag-stabilize it a little.

I got a steel plate at my local hardware store, did you try there?

It's not stable as it is, try it as per the below diagram with a hollow tail made of wider tape.

"scrap" although several feet of manure would make a good, if malodorous, backstop

I will however add that I made a projectile that looked quite like the one in the diagram, but it failed to stabilize and impacted sideways, breaking in half. The solid piece must be very short and the hollow region very much longer. Mine were about equal, as in the diagram.
