Fin-Stabilization and Hopper Loading

Pics of the tenative mounting position:

 

Side view, would be as if sighting down the marker:

I hope this clears some things up.

 

I think you have your work cut out for you. I think you will find that you will not only have to mill the inside of the adapter to allow passage of the projectiles, but will also have to ensure the adapter is the right length (in relation to the projectile width) to prevent binding between the projectiles and the feed cylinders.

On a related note, do you envision this to eventually be a side mounted, or more a top mounted magazine.

Okay, since this drum seems like it could also be used for normal paintballs, I'm going to assume you mean that you don't want to alter the marker to where it would no longer work with a hopper. Is this correct?

the only way this would work is if you swung the elbow away on a 98,then maually loaded a round....still either drum,breakopen or etc....

• Which is exactly what it does? (Uses drum as chamber or has a long bolt travel)
• Why, exactly, are you trying to avoid it? (Whichever applies)

Or modify a marker to accept the drum feed in the same way the Thompson submachine guns did.* It would require either a longer bolt travel (to push the projectile forward out of the magazine and into the chamber), or a strengthened magazine where each separate location for the ammo actually acted as the chamber (like a revolver cylinder) during operation.



*Whoa, that's a lot of dremeling!

Feed elbow, Mk I:

I went a little overzealous on the tooling, and the upper channel is a bit much. I have another, or I can get some epoxy clay and retro fit it. On that note, since I don't have a large selection of tools, I could use the clay as a smoothing agent for finishing.

Paintballs get jostled as they slide down the feed. As long as they stay faced, its not a problem. Also, there will be some spring tension from the magazine that will prevent them from getting obnoxiously out of kilter.

But the thing is going to get jostled going down the feed elbow. 

why dont you just get a discarded round?dont steal,but just like buy one or something
