    Default Anyone willing to show off their home made action fixtures?

    Hello everyone,

    I'm new here, happy to be part of the forum. I'm starting to put together a home machine shop. Basically just a small garage shop that will be dedicated to building custom rifles. Mostly bolt actions, but I'm sure there will be others. Right now I blueprint my own 700 actions. I plan on making my own actions way down the road.

    I have to come up with a solid design first and get my shop finished. Right now I'm using the machines where I work after hours when I can. So instead of spending money on custom actions, I spend every spare cent on my own equipment. Until then, I'll be building on 700 and M70 actions.

    To the point, I'm wanting to make some action fixtures. Mainly for Rem 700 pattern, I would like to make one that accepts both short and long actions with reliefs cut so I can insert and run the bolt while fastened to the fixture. Same goes for the M70 but I want to cut my teeth on the 700 fixture first.

    I was wondering if any of you would be willing to advise on or share your hone brewed action fixtures? Honestly I would be interested in any gunsmithing tool ideas you would be willing to share? I've googled and found a few different designs but thought maybe it would be better to just ask experienced machinists here. Not looking for nitty gritty details, just general ideas.

    Thanks for reading. Feel free to post off any home made gunsmithing tools you like...

    Bob Pastor's "Viper" fixture is pretty much the standard bearer for this.

    Simple design, easy enough to machine. If you're going to DIY, may as well make one fitted to a backplate and avoid the additional stickout of placing it in a chuck.

    I appreciate the ideas. D. Nelson that is great looking work. The V-Block type setup is what I'm wanting to do. That's also a great idea having barrel v-blocks that will mount to ways on the bottom.

    I have some aluminum bar stock to make my fixture. A piece of 2x2x12 and several shorter 8-10" pieces I can machine for barrel vise blocks. Really amazing work I appreciate you sharing it. I'm drawing out my dimensions and figuring my layout. I have yet to decide what upper vise opening diameters to use or make some brass bushings to exchange out for different barrel diameters. I have brass stock to cut bushing halves from.

    If you stay on the taper only you don’t need bushings it will be straight. As long as the v blocks on the bottom are the same. But I just zero the B and C axis with a probe routine.
