  • SS Rifle Rest Project

    Back in '95 or '96, not long after I'd started subscribing to Precision Shooting magazine, Dick Wright did a review of a heavy (30+lbs.) benchrest front rifle rest made by Gary Hayes. Gary used(s) 316SS throughout, and even though there was only one B&W photo in the article, you could see the excellent workmanship. I told myself that when/if I ever got a decent lathe & mill, I'd make one of these rests for myself.

    Well, the lathe was purchased in Dec. of '04, and the mill a year later - I figured the rest project would be as good a way as any to familiarize myself with the mill (my first, and the only one I've ever operated) and the Newall C80 DRO I bought & installed. A trip down to the Surplus Yard in Wichita for some SS & brass was necessary, then the chips started flying (more like the strings started stringing with stainless).



    I had just gotten started boring out the hub when the lathe's single phase motor crapped-out for the last time - I'd already had it out of the motor cabinet several times to clean up the starting circuit's contact points, and had even replaced them with a new set - and had made up my mind that the next time it screwed up was going to be its last. I'd purchased a good heavy duty 3-phase motor locally, and ordered a TECO FM100 VFD from Dealers Industrial, which arrived the morning before I took off for the SHOT Show in Vegas.

    After getting the VFD wired in, I worked pretty steady on the project to finish it in time to display on my table at our club's annual gun & collector show. There was a delay while waiting on a tool order - I needed better quality taps to thread the stainless, so ordered several R&N gun taps (spiral point), along with Titex parabolic flute cobalt drills. The combination of cobalt & the parabolic flutes has worked very well in even the toughest of the ??? alloys I picked up at the Yard - I'm a believer in these drills, and will be purchasing more of them (Cleveland & Titex) as needed. Dittos on the gun taps - sure beats 4-flute plug-style Hansens, which are all I can find locally.


    I wanted a fine finish pass on the hub & legs, so used 222 T15 inserts in Warner toolholders - they give a nicer finish than the TCMT 32.51 carbide inserts I had at the time for the cheap import 5/8" shank toolholders I got with the lathe. However, I think I'm starting to see some rust on the tops of the knobs that were finished with the T15 inserts - it looks as though perhaps there's some steel off the inserts imbedded in the SS, and it's starting to rust. I recently bought some surplus Sandvik 32.51 finishing inserts off e-bay, and they appear to work at least as well as the T15 inserts for light finishing passes.

    The mariners wheel for fine elevation adjustments is made of brass - couldn't find any bronze during my rummaging at the Yard. I drilled & bored the hole, then threaded it to fit the 1-14NF threads of the post with a Carmex internal threading tool & laydown inserts. Holes for the 304SS 3/8" spokes were drilled then reamed for a snug, press fit.

    The top is 2024-T3 plate, rough sawn, then milled to suit. I used a HSS tool in a flycutter to finish the face surfaces of the plate, rather than leave the mill surface. In retrospect, I'm wondering if leaving the mill surface would be better - the finish I left with the flycutter (even with a pretty conservative feed rate) seems rough enough to have a tendency to gather & hold dust. If there were a local anodizer, the best course would have been to have the top's parts plated.

    Overall, it was a fun project, and I got a lot of complements on the finished rest at the gun show. Best of all, it's something I can enjoy using, and seems even more stable than my rusty old Hart rest - but then, it's nearly twice as heavy as the Hart.

        You need to use the image tag on both sides of the link to the picture you wish to display here. "[img]" in front of the link and "[/img]" on the back of the link WITHOUT THE QUOTES. Doing so will make the picture show up in your post.

        The link you posted takes us to YOUR loggin page for your photobucket account. We cant do anything on that page without your password.

                Lol,THAT would be the EASY way Wolf!

                I'd like to see him learn how to do it since it's so easy. Its just hard to communicate board code via the net. Once he figures out how its done he will be able to share his pics here and elsewhere on the net.

                  If he does.Oh and perhaps with the new board it may be impossible for a while.

                      would really like to see your rest.

                      there's two parts to posting a picture. First you have to have a place to put it on the web. I have my own website so I use that. Most other guys seem to use PhotoBucket. Once the pic is posted you call it up on your screen so you can "copy and paste" it.

                      Then you come to this forum and in your thread you put the curser on a line with no words on it and do a "left click" on you mouse and hit "paste". It will put your copied address line there like so.....

                      Now to make it so others can see it put [img] in front of it and [/img] on the end leaving no spaces. That's all there is to it. Now, where's the damn picture

                      Thank you to our families of soldiers, many of whom have given so much more then the rest of us for the Freedom we enjoy.

                      It is true, there is nothing free about freedom, don't be so quick to give it away.

                            Aw right, you guys, I'll give it another shot. I couldn't even get the damned photos into the album on Photobucket so I could see them. All I got was about 2/3 of the first one, and never could get the site to put the 2nd photo into my album. Finally got disgusted with the whole thing and went back out to the shop to work on the 2nd rest - much more satisfying, and not nearly as frustrating.

                              sounds like a triple whammy 'win' project; you got to learn some new tricks, upgrade one of your machines, and have a better bench rest too. I used one of those orange Lyman aluminum rests for probably ten years, then a guy traded me a trigger job for a heavier metal rest he made. It was better, but had too much slop between the base and the pillar. About three years ago I machined some delrin bushings and a better top; now it's actually good enough to replace some day with something more serious! My buddy Dan still shoots off that orange Lyman; he can generally outshoot me on any given day. As others have said, looking forward to pictures, Flat. Your sister Ann give advice???
                              I'm here hoping to advancify my smartitude.
