"Bubba" & the "Maulernator"

Unread postAuthor: sgehring » Fri Dec 22, 2006 1:47 am

This is my first, Bubba, and my second, The Maulernator, Pneumatics. Bubba has a 48" by 4" chamber and a six foot by 2" barrel. The valve is a barrel sealer I made in a 4" tee. It uses a modded sprinkler valve and blowgun for a trigger. The tripod is made from expandable poles designed for paint brushs. They rotate back to be out of the way for travel. At a 45 degree angle it will launch spuds and ice balls out of site. PVC Arsenal 17 was great help in building this one.
My second is the Maulernator. Named for the Mauler valve I bought from Gort. Gort makes a great product and was great to work with. It has a 32" by 4" chamber and the stock also adds to the chamber volume. It holds about 430 cubic inches of air The barrel is a golf ball barrel made from 2 pieces of sch 40, one inside the other with a 1" slot cut out of the inner sleeve. It holds the golf ball very tight. If you put the barrel tight to the floor the ball will not make it to the bottom of the barrel because of the trapped air. The barrel is removable and is a breechloader. When the "handle" is in the up postion the ball drops in. Then rotate to the right to the stop and the hole is covered by the tee and the barrel seals. It's a tight fit to rotate the "bolt" and it seals up good. The bolt is a 2" tee with the stops taken out. The Mauler is triggered with a modded 1" spinkler valve. The hose is braided stainless steel to the push button blowgun trigger. It has been test fired to 100psi. It cleared the parking lot of snow when it went off. Just a huge white snow cloud in the air. Future plans are to finish the paint job on Maulernater and to paint Bubba. I found 4-twenty foot pieces of SDR 21 at my step fathers so a 20 foot barrel is in the works to test both guns for distance. I have two 10 foot pieces of 1" angle iron that will be hosed clamped to the 20 foot barrel so it doesn't sag as well as wooden supports to hold it at 45 degrees. I am going to sleeve only the first few feet of the barrel with sch 80. Bubba will be getting camlocks for changing barrels out. I am attaching the links to the pictures. Let me know what you think!

Holy fork! I am extremely proud to have my valve on a gun like that. You did a very sweet job on that launcher. It looks sooo sexy!

Its a little heavy to shoulder but I can do it as long as I don't have to hold it for long! Great way to clear mysidewalk of snow. Was just testing it and had about 1/2 inch of snow powder on sidewalk and when I set it off cleared about 3o fewet of snow, Neighbors lights sure came on fast...

Very nice configuration!
It looks like you have switched those fittings around till you had them exactly the way they suited you.

Nice to see you used a mauler valve!!

Really nice work. I'm glad to see you have it working. I especially like the bipod. It looks like one badass mortar!

And the new one with the Mauler, that's just amazing.

Both of them are awesome. I like the stock on the mauler valve one but the whole gun looks a little bulky for a rifle.
