AWS Back Purge Welding Fixture 4

[Music] all right guys we're gonna get back on our next component for our back purge fixture here so what we're going to do is we're going to make the two clamp bars that go on top of the fixture right here so here's our drawing and it's two pieces of flat bar 12 inches long three inches wide they have two slots milled in it and then we have that 30 degree angle that we're gonna cut across one one side of it there so we'll use our do-all mil-to-mil in the side links there are two slots and then we're going to go to the shaper and use our shaper to cut the angle across the top there so real simple easy parts there to make this is our piece of material so the first thing we'll do is go to the bandsaw cut two pieces and then we'll go to the mill pieces are going to be 12 minutes finish link so I'll cut them become like 12 and 1/16 that should give us plenty of metal the millions clean we are running our new bandsaw blade from the MK Morris company and it's doing a good job all right let's get the mill set up so we're gonna use some parallels here and because of the length of the work piece here is 12 inches long instead of centering it in the vise and working out here on the ends I'd rather it be close up to the vise to do our working right here you know do our milling and in our slotting only eats in there as well because you're gonna get a little bit of deflection out here if you if you mill it out here on the ends it'll probably work but I like it up close to the mill vise so what I'm doing I'm using this des as technology multi axis mill stop right here I've got it set about where I wanted and we'll push it up against the stop like so and then we'll be able to work off this in for every end all we got to do is mill it flip it around mill that in same thing with the slots one when we get one side milled we can flip it over and do that we're not having to move the table back to the core so that would be the advantage of using the mill stop now we're also going to use my parallel separators so you got these parallels in there all right and I've had a lot of people ask me about this I've shown this a lot in my other videos when I was working at motion there so this is made by edge technologies and it's a parallel separator so what you do is compress it and then drop it in all right Center it up there and just make sure your Pell parallels are pushed down and what that does is that these keep your parallels push back against your vise jaws so that whenever you take your workpiece out your parallels are not falling you're not getting chips and stuff back in behind there so that's what that is there so that'll keep them nice and clean and we don't have to worry about our parallels all the times that we move this so we'll set our workpiece in there easily slide it back till it touches the stop and then tighten it up now we can just work off this right in for all of our all of our operate first thing I'm gonna do is go ahead and just check what the overall rough length is using my asterick vernier calipers so we're looking at so it looks like about 12 inches 80 thousandths is our rough length so I know what we can take off there so we'll touch this in and just take about half of that so we'll take about a forty thousands cut I'm gonna be running a half inch carbide end mill here it looks pretty good and I got the step pulley set at 1,100 rpm cheering out the Dro we're going to step it over 40 [Applause] looks good alright so what we'll do now I'm going to take this one out then move our table back over because we're going to keep our position right where we're at I'll grab the other workpiece drop it in we'll do it again slide it down against our stop tighten the vise it's like that alright so now what we can do is just go ahead and flip it around bring the tool back I figured it would skim it a little bit right there so we'll go ahead and get a measurement with our verniers now and see what it's at all right that feels pretty good so let's see what does that say it's going to be under 50 so where we're at 40 it looks like 45 thousands that we've got to take off there at last cut I only took 40 on the dial there so I should have about 5,000 Stu let me get a better look at that up close it looks like it's showing four thousandths all right it's on it's lined up on the four line right there so we'll do a climb cut on that negative make it our our even 12-inch Ling [Music] alright one more check here to verify it just make sure that the tips of your calipers are even when every year whenever you're using these I use my left hand to kind of hold that fix jaw in position and then use my right hand to rock the the caliper to get the feel that I want make sure that it's nice and squared up and it looks like we're on it 12 inches exactly alright so just going to repeat that with the other one there get it milled and then we'll move on to our slot we're going to go ahead and use our half-inch edge finder to find the edge and Center up our slot location will be so slots going to be one inch from the edge and it's going to be centered in here one inch long all right so we got it we moved it over inch and a quarter we added a quarter inch because of the width of our it's finer there but what we're gonna do is go ahead and move it back over so that we can get the bat side there since I'm down in the vise I'm going to use a 7/16 drill bit and we're going to drill us a hole on all four ends of both pieces of four holes there and then we'll put our end mill in there and do our millon so that was just a guideline to make sure that I was you know in the right spot there what is Blanche we're good to go let's see if this little mill can handle a half inch end mill and a half inch depth to cut I don't like it screaming too much I will try this Niagara - flute high speed still in mill and if it if it's wanting to chatter on me on a full half inch depth then we'll just do it in two cuts we'll do a quarter inch per cut here [Applause] yeah it's just too much yeah I can't handle it so what we'll do I want to come over here and just touch off I'm gonna zero out my readout here on the quill and we'll just take half of it go down a quarter-inch right there that's better go back to our zero we'll finish it out now I'm going to take a five thousands cleanup cut on that one side clean up that step there this is this is just a slot for a bolt a little bit of clearance isn't gonna hurt anything that's the first one finished out I'm gonna go check it make sure that it gets the fixture [Music] [Applause] I'm going to use my Noga tool to deburr the slots this guy right there [Applause] let's see if this thing puts up those are clamp plates I think that's going to work there we go good fit and then he can you can pull these things back you know you got into where you can just kind of position them where you want there so all right next up is the shaper we will set the tool head at the 30 degree angle and we'll use our automatic down feed mechanism on there and cut our 30 degree bevel on there [Music] [Music] [Music] [Music] [Music] you
