An AR style barrel vise will do .
Don't need an action wrench, just the savage barrel nut wrench
You can do it with wooden blocks and a vice, but a barrel vice makes it so much easier
Just the barrel wrench and blocks ( ar-15 and a bench vice to hold the blocks )I would not need an action wrench too? http://northlandshooterssupply.com/wp-content/uploads/2018/05/ACTION-WRENCH.jpg
The pics i am finding of barrel vises look like wood blocks. I could put wood blocks in a bench vise for same effect?
Two large blocks of dry hard oak. Clamp them together and drilling the center.
You are overthinking it. A straight hole will work just fine, the wood confirms to the barrel enough to grab it.But the hole needs to be a tapered hole right? The barrel is tapered. How are you drilling tapered holes?
