Supporting the spud gun (bracing)

Unread postAuthor: NP Carling26 » Sat Jun 25, 2011 10:48 pm

I have constructed a spud gun using the over and under design. My barrel goes over my compression chamber and is connected via two right angle adapters. The right angles support one side, but what are some recommended ways of supporting the other side so as the weight does not cause the gun to sag? I appreciate any responses, as I know I am new here, but it's something that I think I will enjoy and I'm very excited about just recently finishing my first pneumatic (first in general) spud gun.

Welcome to spudfiles!

I assume your talking about the front of the chamber and the barrel above when referring to the other side. An easy way is to simply measure the distance between the chamber and barrel at the rear where the adapters are then sit down with a protractor and draw one circle the size of your chamber, and one above that the size of your barrel, making the distance between the two circle edges the same as the measurement you just took off the gun. Then draw a line from both outer edges of your top circle, to where it meets the bottom circle, forming a shape like so

Then get anything that is easy to cut like a block of wood, or hard foam etc around 3cm or so thick, and stick the paper to it so you have a template. Then cut it out like so

Then stick it between your barrel and chamber at the front, then buy a couple of screw hose clamps (they are metal straps with a screw that tightens them) from the hardware store that fit around your setup then viola. You have a brace[/img]

Edit: I have no idea how to put images in designated areas of a message. The first picture was meant to be where it says image at the top, and 2nd at the bottom.

Thanks, I appreciate the response. Do they make hose clamps that large, there is probably close to 10 inches between the bottom of my compression chamber and the top of my barrel.

They do sell them, just a matter of finding that size. Otherwise you can use anything from velcro straps to cable ties.

You can also put multiple together to make one big hose clamp
