Huben Huben GK1 .22: A Beginner's Journey to a DIY Mini Carbine

Custom Bottle Clamp

This was perfectly functional…but I decided to try my hand at designing my own bottle clamp. Mostly for the fun of it. But also because I wanted to add side rails to the clamp.

Here was my design process.

The bottle is 32mm in diameter. I based the diameter for my clamp on 33mm for some extra space. I felt 5mm wall thickness would be sufficient. And about 20mm at the top gap for clearance of the barrel. With these measurements I designed my toilet seat:

Continuing with my personal preference in design--I decided I wanted to make this a 3 part clamp. I kind of like this design because the clamp can be disassembled--that way you do not have to slide it on.

So I broke the outline into a left clamp, a right clamp, and a center block.

I’ve added a few more details.

Slots to index the pieces together.

I’ve got the outline of the pic rail on the center block. I will add the side pic rails later as I will design 2 types--with and without side rails.

That's promising, I've work on a few detachable and extensible rear stock option, even folding ones for my GK1 perfected mod, that would screw on the rear port of the mod, but seeing as NOBODY download it or show any interest I kinda left it in limbo cuz I'm more of a pistol guy and not really interested in carbines.

My final config for the gun, for now is that:

Add a power regulator, lenght adjustable trigger, shorten the overall lenght, improving A LOT the precision discarding the triple barrel to slide pressing design and leaving a floating barrel, and finally made a silencer that no matter how ****ed up from factory your treads are, is gonna align with the barrel because it just follows it thigtly before the screwing, and it's backwards compatible with my silencer mod.

I'm not gonna upload it, because you don't deserve it.

Why post about it, if you don't want to share it? Doesn't seem to be in the spirit of the forum.
 
Custom Bottle Clamp, continued

And here were my finalized 3d designs.

They look a lot more advanced than the silhouettes I designed above, but the conversion to full pieces was pretty easy when done in steps:

  1. Push the silhouettes to their final length, 45mm
  2. Added a front lip to the clamp sides to index the pieces together to get the holes to line up
  3. Added the front little decorative V to the middle block
  4. Rounded the center block surface that interfaces with the bottle.
  5. Added the through holes with the countersinking
  6. Created the picatinny blocks, and merged them
  7. Softened edges
