This is no better. I'll give up now.

Well, once I uploaded the videos that I had on the cell phone, one of them looks kinda' OK. Let's see if I've got this procedure figured out right. http://i252.photobucket.com/albums/hh2/TullieD/th_20130907_1804031_zps390c3e94.jpg Duane Edit: It looks fine on my PC, but the link that I posted only s...

We made about 30 shots Saturday, without streamers. (I thought that I had a roll of the Orange surveyors tape in the truck, but didn't) Didn't matter. The bright colored balls were plenty visible without it. :) We kept shooting the same 5 balls, with kids collecting them and throwing them back. No b...

Moderators: I know this is a duplicate post, but I wanted to make sure that those that wanted to see it did.

Well, I took the tennis ball gun out to my friend's place this afternoon, and we fired it about 30 times. All of my previous shots were at low pressure, about 25 PSI, with compressed air. Today, I was using CO2, from a 20 LB cylinder, at about 75 PSI. I've got a 150 PSI regulator on the cylinder, an...

Correction, FUZZY BALLS !

I've had my gun done for a while now, but so far, I've only made a few low pressure test shots in the neighborhood.

Tomorrow, I'm going to take it to a friend's place out in the country, and see what it can really do.

Wow ! Cool Gun !

Thanks,

Duane

I'm still going to give it a try. Every hole saw that I've ever used made a slightly larger hole than they were "supposed" to make.

If that doesn't work out, I'll go to plan B.

Thanks,

Gun Freak,

I don't know how well it works yet. I've only done one very low pressure shot (25 PSI) because I don't want to freak out the neighbors.

After I brace the barrel/chamber, I'll take it out to a friend's place in the country to find out. Hopefully this coming week-end.

Duane

You got a few options. You could cut out a bracket and then zip tie the barrel and chamber together, for example. Or a large hose clamp. Or something. :) Blitz, I've got a friend bringing me a 2 1/2" hole saw, which I'm going to try to use to make a wooden brace. And I have a VERY LONG hose clamp.....

Well, I've made a "little" progress. 8) After playing with performance numbers from GGDT, my idea for a tennis ball mortar turned into a tennis ball cannon. Maybe next time. :) Sorry about the crappy photo... I am not known for my photography skills. http://i252.photobucket.com/albums/hh2/TullieD/20...

Tennis balls, that is. http://i252.photobucket.com/albums/hh2/TullieD/DSCN1585_zps9fd7bf02.jpg This is a box of 50 Tennis balls that I bought off of EBAY. There are literally thousands out there, and some can be bought really cheaply, with free shipping if you look around. They're cheaper than potat...

I love it when my friendly brown truck driver pulls up outside.

Blitz,

Pictures will come. Be patient. Old men don't move fast. 8)

Thanks,

Carnee, I'm new to this myself, so I sure as heck don't know all the answers. However, there seems to be a very simple fix. How about just not holding the trigger after the shot is fired? BTW, what you've described has nothing at all to do with how a double action "real" gun works. You may want to a...
