Fireball Tool Fixture Plate Part 8: The Lost Footage

[Music] welcome back guys so we're getting to the last phase of the fixture play here and then and the one where we're gonna put our whole pattern in this and this whole pattern is will be used for mounting hardware so that this plate can be used to hold and fixture a part that has to be machined so you have a series of holes tapped in here and you can set your part anywhere on this plate that you need to and be able to put studs and hold down straps wherever you need you know to hold that part so that's what we're gonna do and I have an idea to go with half thirteen and quarter twenty holes in here we're gonna start with 1/2 thirteen and I'm gonna figure out the grid pattern that I want for the smaller hold-down kit I have a small hole down kit that was given to me by a viewer Paul Boulay and I will show you that later and show you what it'll be used for on this plate so we're going to go to inch centers you know we got a ten inch by ten inch plate right there and we're gonna go to inch centers and I'm just gonna what I'm going to do is I'm gonna put me some witness marks on here so that as I'm laying this thing out going in there and drilling it I'll know that I'm I'm on the correct pattern so we're just gonna just going to put some marks just about where it needs to be start with the ends like that so we're one inch one inch from the from the corners and this is just about just about dried out we're not getting much so that's what we're gonna do right there and then we can go across here with this square but and we can put our two inch just like that good we'll put one right there all right I'm just gonna continue doing that around the whole plate I'm going to use this corner here as my zero start location I'll find this edge and this edge and we'll find the corner of that and have that zeroed out to absolute and then we're going to move over to our first hole location and we'll use the incremental on the digital readout we'll start with a zero there and then I'll just build a step over two inches four inches six inches 8 inches and the same way this way two four six eight and just keep up with our movement without doing any kind of zeroing every time a little more speed there and I had I ran the the y axes this way to make sure that I had enough travel and we got just enough travel with everything set where it is right there all right so that's going to be our edge on that side I'm going to zero it out we're going to move to 50 two-fifty I'm gonna throw it out right there and then we're gonna come over here to do this side all right 250 zero all right so now we have a absolute zero data point right here on this corner this is zero zero so any hole pattern that we want to do after this we can just go right off of our absolute reading on the Dro and we got her an absolute so we're gonna go ahead and move over one inch that's going to be our start location try to get as close as we can alright okay so one inch one inch now we're gonna go we're gonna hit incremental and now we're gonna zero these so that's what we are our whole number one now we can just go to inch increments every time so here's my plan of attack I've got this brand-new 2764 Cleland drill bit I just picked up a full set from KBC tools and these are what I've been using to spot end holes instead of Center drills but with the short length if everything's good you don't have to Center it and then put another drill in there so we're going to use this drill to come down and just spot it and drill it at the same time alright and then we're gonna power tap it using a half thirteen gun tap and we'll see how this works now my plan is to not chamfer it before tapping and I don't like doing that because I like to have a chamfer for this to follow into but the thing is I want this to look consistent so my plan is to drill and tap and let's see how that works and I'm gonna come back to you all these holes with a chamfering tool with a depth set so that every one of them are the same depth and it'll look uniform across the whole plate so let's go ahead and try the first one and see how it does we're gonna try this I've had a few guys ask me about this keyless chuck right here a viewer had given this to me quite some time back for about a few years ago this is the vertex brand so it's an imports an Asian import but it's absolutely flawless it's it runs perfectly true and I love it it's got the integrated or a chanc built into it so you don't have to put it into a collet you just stick it straight up in the spindle we'll try that power tap and it's got a it's got a hole in there that I can use the spanner wrench if I need to tighten it up a little bit more if it doesn't want to hold that tap all right we're on a whole one so let's get started here we're not using any Lube that's another question on off and yet you don't have to lose cast iron it's actually better if you do not Lube it there we go now we we are going to end up having to take this thing apart so that we can clean all the chips out of the the inside underneath that plate but we'll do that after we're through with all of our machining all right and I think I'm gonna set up a vacuum and just back in these chips up as we go let's try our tap and see what happens here I'm gonna go ahead I can't ever get these things tight enough for these taps that's why I'm worried it's not going to work I'm going to go ahead and use this spanner wrench and tighten it up a little bit more see let's see what happens there looking good looking good all right I'm gonna need to put a mark on that tap with a paint marker so that I know that I don't go in and and touch the bottom of this mounting plate that's it's about where it needs to be as far as full depth so it looks like our are just our drilled hole is gonna work for lining up the tap we're not gonna worry about a chamfer this time yep let's go - it's gonna be 2 inch every every 2 inches I just start to drill kind of gently at first and let it get itself centered up and then send it home I think our spanner worked pretty good for torque we needed on that Chuck for anybody that may be wonderin see you use hold down hardware like this on here or a bolt whatever like we got a good fit about our first Road done so now we're gonna go another two inches in the Y start our second row got my yellow witness mark on the top there that's the point of no return for the tap all righty that was our last hole to tap there for a half thirteen so what we're going to do now is go ahead and get us a transferring tool set up and we'll get our depth set on this hole and then we'll work backwards through the grid all the way to our first hole all right we got us a good Champaran tool in there and I've got my stop setup here on the on the quill my adjustable stop we're gonna go ahead and just lock it down right there I was going to speed it up run 135 I'm going to run the knee up manually just a little more trying to clear that first lead-in thread popped out that's looking pretty good I think we'll leave a sit right there just work our grid pattern back the other way now that I've got the stop set up here just come down and chamfer it just like that each one and they should be exactly the same death all right last hole all right now I will point out I swapped chamfering tools I found I wasn't really happy with the the finish that I was getting with this one here that's what I started with I found another one that still basically knew had a cover over it and it's leaving a much better finished on there so I was about I was through with these two rows so I came back through these and touched them so that they would match the finish that this cutter was doing so now they all look about the same all right well that is looking good that is look starting to look more like an actual fixture plate there all right well that's going to conclude the half 13 holes so what's up next now is to put the quarter 20s in there and I'm still debating in my head the grid pattern the layout locations that I want to put those at because I want to do both the quarter 20 bolt and a drilled and reamed hole for a dowel pin and I'm just trying to decide on where I want so let me get that figured out and I'll bring you back all right I think I decided what we're going to do now so this is one of the hold down plans for the quarter twenty and one of the bolts that comes in the kit and then we got our dowel pin there so I'm thinking what we're going to do is I'm going to go in between the holes and put the quarter twenty so we'll have them in between so we'll have four quarter 20 holes just like these here so just be kind of shifted you know 45 degrees and then what we'll do is in between them right in the middle of all these we're gonna drill and ream a quarter inch hole for these dowel pins there and that will that will have a grid pattern there so that we can if we ever need we can put a few of these in there two of them or whatever for a fence to back something up against you could also put them at an angle you know like there and there so that's what we're gonna do I'm going to get I'm going to go ahead and put my layout lines on there just like I did before so that I have a visual reference of where I'm going I don't get lost it's it's just easier to have something scratched on here with a char be so that you know where your x mark is that instead of trying to keep up with everything in your head and looking at digital numbers up on them up on the readout so plus I want to get a I want to get a picture of this - all right so I'll bring you back shortly I'm gonna go ahead and get my the diameter of the drill started there just like so and we'll just lock it right there now I'm gonna zero out the quill up here see how she does we're gonna go to 375 I think what I might do is set up a stop so there's our depth right there at 375 now I could do that and just visually watch that every time but it might be a little bit easier if I just go ahead and set up that stop the same thing I used before this guy right here just clamp it onto the threads and then just come down to the stop that's probably what I'll do though well I have to look at this and manually get it every time we got our stop block right there and then we've got our zero on our digital readout right there so we'll just go down there to that every time for every hole nice and easy I'll see what I've done I'm actually I haven't finished I haven't finished laying all these out and you go in there that's what's screwing me up I need to go in and lay out some more holes all right that's more like it so I told you wrong I'm gonna be working the even and the odd numbers this time that's all right we got our witness marks we'll be all good to go so you get a couple more of these drilled to show you wasn't it nice having a digital readout [Music] [Music] my plan of attack for tapping these holes I'm gonna use this spiral flu to tap to start to start the holes you know it's a it's got taper there ground on it so it's not going to cut threads to the bottom and we're pretty shallow too you know only a three-eighths depth so we're gonna we're going to power tap it this way and then I'm going to come back after I power tap them all I'm going to use a bottom tap this quarter 20 bottom tap and just the tap branch so I'm going to manually tap the holes all the way to the bottom that didn't work too well I don't think I don't think this keyless chuck is gonna work real well for that so I may have to swap that out this would be a perfect job for a tapping head but I don't I don't own any of the tapping heads to be able to do this operation so that's why power tap it in my real Chuck well we safely made it through all those power tapped holes now let's see if I can power tap the bottom tap my hand now and not having heat issues I think I did the first two already just testing them out I wanted to make sure all the chips were out of the bottom of it so it's not binding up on the tap there all right that's gonna work out pretty good by the way I'm using a it's a Greenfield tap and dye number zero tap wrench this is the one I got from mr. breeze all of my hand tapping is done now we're setting up to do the chamfer just like we did the other tap holes I've got to stop set on the quill here and I'm just gonna come down and touch it just like that put a nice chamfer on let me check that I found a tool that was nice and sharp so we can get a pretty good finish on it there and I'll just go through the grid pattern and chamfer all the holes they'll be all nice and even what that things finally starting to look like a fixture played isn't it and it's looking good we've got all of the holes tapped chamfered blown out all those are done so the last step that we're gonna do is we're gonna go in between them right in the center here and we're gonna drill and ream quarter inch hole for our dowel pins to slip in there all right so that's going to be the next step I'm real happy with it I like the way the the pattern is looking up I wasn't sure without seeing it actually machined in there but now I'm I'm real happy with it and I'm gonna grab a couple little clamps so you can see how it works I'm going to give you a better overview of this of this kit but we're going to wait until we're done but so you know you have some little finger clamps like this that Paul made and then you've got bolts and you've also got studs that you can put into these tattoos here just like you would the half-inch all right and then you can use this as your stud for your hold downs okay so with that with all those holes you should have a good pattern there to be able to hold some kind of hard part and we might find something around here that we can use as an example to hold down if used to have to do some machining all right and there's other pieces that go in here to hold the heel of the clamp up and things like that but like I said we'll go into that once we get this completed and we'll show what all it's capable of all right so onto the drill and reamed holes [Music] [Music] [Music] [Music] [Music]
