You will need a barrel vise with the correct size insert to fit your barrel, some powdered rosin, an action wrench to fit your action, and a BIG vise well-bolted to a VERY sturdy table. Depending on the type of bbl vise, it may bolt to the table itself & eliminate the need for the vise. After the removal of the original barrel, it's not that big a deal, as you only need to tighten a bbl up to about 100 ft/lbs, max. I watched Shilen (the son)reinstall the bbl on my .300 WBY, and he just gave the wrench a hard spin to tighten it down. Kinda like he let inertia, and the sudden stop set the bbl in place. Most actions are a bear to unscrew the first time (Remington uses loctite), but after that it ain't no big deal. I have been intrigued by this idea for a long while, and am just now going ahead with the project. FWIW,,,,,,,,,,,,,,Bug.
