We know some guys who make their own stocks, and others who do their own chambering. But consider this, Robert Carnell of Australia built his own state-of-the-art, water-cooled, tension-barrel Rail Gun, even including the action. That’s right, Robert designed and crafted his own precision action. This has got to be the ultimate home gunsmithing, do-it-yourself (DIY) project.

Carnell is an accomplished benchrest shooter and past Australian Sporter Class Champion. In 1993 he won a Silver Medal at the World Championships. But Carnell is far more than an ace trigger-puller. Robert is a skilled and creative “home gunsmith” who has crafted his own custom action and built his own railguns from scratch. Robert also runs the Austrialian Benchrest Bulletin website.

Home-Built Rail Gun — Aussie Innovation
Below are photos of one of Rob Carnell’s most amazing builds. This liquid-cooled, tension-barrel rail gun is a great example of self-reliant Aussie engineering. The barrel runs inside a coolent-filled, large-diameter sleeve, much like an old water-cooled machine gun. This is the fourth rail gun that Rob built, and the second fitted with a tensioned barrel.

Robert explains: “My railgun design has a 1.75″ barrel under tension inside an aluminium tube filled with radiator coolant. There is nearly a gallon of coolant, and the barrel stays cool no matter how many shots I seem to fire, or how quickly they are shot. The brass nut on the front rides on a nylon bearing and can be tightened to get the best accuracy. I am a believer in the ‘tuner’ idea and this seems to work for me. The main tube is thick-walled aluminium 600mm (24″) long. There is a flange at both ends. The flange at the back fits onto the barrel before the action is screwed on. The front flange is a press-fit into the tube, then there is a brass nut that fits over the barrel and screws against a nylon washer on the front flange. The Railgun’s base is aluminium and has the standard adjustments — windage, elevation and a sighter cam. In addition, there is a 1/10 thou dial indicator for windage. This allows me to zero the indicator and shoot my group. If I need to add a bit of windage for a condition, I can quickly get back to the original position if my condition comes back.”

Home-Built Action Uses Rem Bolt
Rob’s rail gun uses his own home-made stainless action, which features Panda-spec threads and a modified Remington 700 aftermarket bolt. Not bad for a do-it-yourself project we’d say! CLICK HERE to read how Rob designed and built the action.

Meichelle regularly shoots F-Class in Australia. She has traveled extensively to compete in major matches. Here is a photo from one of her favorite ranges in Australia. Looks like a beautiful place to shoot. And we love the printed fabric on the range cart! Kisses from Down Under.

Jimboomba — Place of Loud Thunder and Little Rain
Meichelle resides in Jimboomba, a small township located south of Brisbane in Queensland. Jimboomba is named after a sheep and livestock station based where the township is today. The word Jimboomba (originally Gimboomba) is a Gugingin word meaning “place of loud thunder and little rain”. The Gugingin were the first native Australian peoples of this Yugambeh region, now part of Queensland.
