Making Scope Rings for the Browning A Bolt 3 - Part One

so all the projects I make are not for you guys sometimes I like to make things for myself so what I thought I'd do this week is to show you guys one of the projects I'm working on and let you look over my shoulder as I build it do something a little different for a change the Sun tonight a while back decided we'd like to try a little long-range shooting so we bought what some browning Abel three rifles I bought a 300 Winchester Magnum and he bought a seven millimeter Magnum and we got scopes as well the scope I chose turns as it turns out the body the 30 millimeter body is too large for any of the commercially available scope mounted rings but I like one-piece rings especially since we're gonna be shooting out any work from 600 to a thousand yards I think I feel that solid one-piece scope rings would be a better option of the two-piece ones that mount on a rail so I designed up set of scope rings to fit my rifle and fit the scope I bought and I used normally I do my work in SolidWorks I get I get a lot of questions and what kind of what CAD system I use and I do use SolidWorks but I'm able to use it because I can bring the copy home from work to use I think I'm allowed a seat at home it is a commercial professional CAD system so it runs about four thousand dollars a seat so it's a little pricey for your home hobbyist but just for fun and I came across this 3d CAD program called on shape it's invented by the same guy that first invented SolidWorks so it's a lot of the features are similar the difference is that it's a cloud-based CAD system everything you do is on the cloud you don't have to have a program you don't have to have a supercomputer to run it you can even do it from a smartphone or a tablet so I start playing around with it a little bit and it's pretty powerful it's it's flax a little bit of functionality right now but it's new I'm sure they'll bring a lot more to the table once it's been around for a while but I drew up these are remodeled up this is scope ring these scope rings I don't know if you can see them you get a pretty good job everything all the necessary features are they are functions so anyway I thought I'd fill up these this set of scope rings today or this pair of scope rings and let you guys look over my shoulder it's for a little change of pace so starting out with I I already got the stock squared up you know two pieces figured I wouldn't bore you with that I've done enough stock squaring videos so skip that but basically the only thing I did a little different is since I am making two sets of these I when they do that it like to leave the stock in a long piece and square up four sides square up each end of the long piece and then just slice off what I need in this case two pieces just slice it to set it in the vise and then take one more pass on the end it saves a little time less parts to handle in the vise makes a little little easier to to manipulate so that's that's about the only thing I did different than in normal squaring so next thing I want to do is I want to drill the mounting holes in these things they weigh an upper and lower mount or upper and lower ring we wanted to drill the mounting holes screw the things together then I'll do all the machining with them assembled so the next thing is I got a drill drill some counterbored holes in the top piece and some capped holes in the bottom piece and that's when those guess that's what we'll get started with let's get going okay so I got the the plant brings stock for the clamp rings if to drill in counterbored for holes in it this first the dimensions are close pretty close some the length or the width and height so I went went through and I always like to put marks on on the side that the holes belong on so I don't get him on the wrong side by my mistake it's always a good thing I always keep them keep a sharpie close but close at hand for doing calculations or whatever and the vise or putting witness marks on the parts it's always a good thing to do so if part in the vise and working out in one hand so I like to use the other part to balance out the vise so it the jaw doesn't when you tighten it down so let's pick up the edge of the part edges it apart looks in line finds finder zero point they've got the brothers zero other dolls or the arrow remove over half the diameter the hedge funder that which is heated with the front edge the holes are centered on the electric arcs on her eyes having worked from the eyes of this going to work for the center pick up each engine zero point in the center between okay hope you guys can hear because I'm not using my lapel mic today because it's such a pain to do the editing so since I'm working on my own stuff here I'm going to skip a few corners cut a few corners hopefully you can still hear okay all right so this is a number six hole it's got a 141 diameter through so that's the number 28 drill and we are holes are 135 thousands up from this front edge out there and the 1.44 t apart so that's 720 each side of center about there that's about right these are two holes and get some wd-40 lubrication they are 390,000 apart zeroed out my Pierrot 390 over yeah I'm touching the Dro of my finger I'm sure I'll get a lot of complaints about that what I do and do it for years lot easier than we're all brothers get to drill a hole my finger circus this is pretty safe at 7:20 this way okay so I missed the fact that the battery went dead in the camera because I'm not paying much attention to it sorry about that but got these parts drilled and counterbored good to go so next thing we do is put the tap the corresponding tap holes in the base let's get going on that okay these whole patterns are the same as in the pampering the upper part so we'll make them basically the same way using one as a spacer and one against the stop here but this time we find the front again because this perch wider than the other one and even 135 products the excellent patients the same so then let the cup stack it should be good to go this time I'm doing a 632 632 tapped hole through when the part works up to no lower quarter inch deep so I'll go deeper than that go deeper than that because when the parts the profile apart is smelt the whole beat you come through them it's one they have enough depth to it silicon it's easy to tap 6:32 tap is a number 36 drill in our whole spacing between then the long direction is what 1.4 40 sets 725 back up again and it down Rolfing accountable we're gonna be deep enough from the color can't beat so I'm not boxing lots of room - chips all right when the business of heart remember okay all right more captain I could power cap it well it's all set up here I think I'm just gonna hand cap it with the cordless drill still power capping I don't use a cordless drill rather than the mill if you knew what this sort of thing I would advise you not do that because requires a certain amount of experience get the tap started square done this enough that I can get it started get on we have to worry about kept going off exits are in on an angle basically just looking at from each direction make sure it's square Square to the part in both directions power tap it in wd-40 makes a great tapping food for lumina it's one like any power tapping there to make sure and get the tap into the Chuck tighten up that you can spin it and that's so tight that it bottoms out and great chat kind of be left be able to slip a little bit at the bottoms up again if you're new to that hyouta power capping practice in some scrap parts don't scrap out a real part learning how power test all right safety glasses using compressed air or machining in general all right socket cap screws here and screw these babies together people dropping them all on the floor leave them loose put them in the vise to make sure everything's well with mine before tightening them down there is a certain amount of place in the through-holes let's make sure everything is lined up on both axes and tighten them down so there's this girl started a scope ring anyway so what do i what do I want to do next I think probably next will the wolf bore the hole in a 30 millimeter diameter hole center gun this is parting life so let me get it set up for that and will will bore some holes okay so got to put a 30 millimeter hole on this parting line centered up so let's find the location and as they post the next you guys can see I guess it is centered in this direction why velvet for this you'll post these prints on the comps techniques website just so you can I don't think they'll ever need to make a sender needs but if they do they'll be there if you just want to look at them and follow along as they as I build it you can do that as well like I said this if you have a Browning Abel 3 you want to put a 30 millimeter scope on it this is the only option if you want a one piece ring so it'll be up their neck that's okay too all right so I can't drill this because it's right on the edge of this higher piece sticking up so I'll have to use an end mill and this is the biggest useable to food endo I have at the moment 13 16 so we use that one punch a hole through it and then we can switch over to a boring bar and board up to size for a lot both that these around knowing on the edge of apartment this might move my table in the X dimension just like that all right switch over to the boring bar and do that same piece but it's easier since we're all set up here just to switch parts a little semi production don't step at a time on each part chicks are sick and the tools that gets heated up so use some oil and slow down a little bit we go this tool offense the original geometry I think the original probably had a little more clearance wouldn't load up like that get the job done all right skip the boring head put in another thing on my list of things to do is to get this their power drawbar back in operation I bought another Harbor Freight impact match for it hopefully this and last longer than the first one I thought about redesigning the whole thing for a better quality impact of entropy it's a lot of work there are things only nineteen dollars that can afford to replace them one or two of them all right I'm not sure what's up with these batteries today but camera seems to be going through feeling pretty fast I may have to break out the power supply for it anyway we got this for finished I know if you can see it turned out pretty nice for focus camera why are we not focusing there it is huh all right anyway that boys the size so let's throw the other one in and do the same thing we're all set now so I can just go ahead mortified nice thing about a boring guy like this you should always be flexed to the inside of the hole so you take an heavy cut like this and then truffle spring cuts would be like to say you can see the spiral the Tooting the cool dragon when they pulled it out there right now we're going to go back through without he's set in more position we'll pick last little bit of stock more thing to be right at 30 which will check their money hey should get BS 1.18 1 inches one point one 1 8:05 so what happened kappa thousand thunder which is perfect leave it right there alright starting to look a little bit like scope rings so next thing I'm going to do I think is put the the two mounting holes two holes that go in the bottom of the board then screw the scope mounts to the receiver on the rifle you think I'll put those in next alright
