Sensitive Micro Drilling Attachment Part 5

all right so I think we're ready for some final assembly here we're gonna use these new little helping hands that I rigged up let's start by putting the a little plate in between so that it doesn't doesn't close down so this is one of those situations you need well you'd like to have four hands or something we're gonna use a pin to line this up get it up in there so let me get real clever here so these are these alligator clip Noga helping hand pills so I can find a spot and walk that down this is quite a happy place there all right and then this one here it's gonna hold this little thing because it wants to be held up just a little bit like that okay all right I get everything kind of lined up on the press no way am I gonna screw up here I think I don't have enough stroke here okay well let's try it here's the pin so here you know I kind of want to hold the pin with with one hand and work the lever with the other and I suppose there she goes see we got hey it still moves good sign right that's it let's get this out of here all right well let's put the other one in all right yeah this goes this pin is pretty short that you bring this down from and that block in there hey they make a custom little fact that diameter wasn't it small enough appropriate way let's give it a little more that looks pretty good all right it's a little stiff but that's okay so we can do something about that it's stiff because I think we're rubbing on that one this one was fine so usually when you do something like this it's really nice to to have like the upper the upper hole a slip fit in the bottom one a light press that way it spreads the flange is a little bit and then you can push it back together but I had limited choices and Reimers and in this situation so all right let's fiddle around with it a little bit loosen it up and give it a try so far so good right so there it is installed and we're gonna give it a try and get a piece a piece of brass here the smallest drill I have is a number 80 I'll look around some more I might have something a little smaller than that but we'll try that to start with so the first trick is to get a spot started on center accurately in a couple ways you can do that you can use something like this single lip cutter here that's got a conical point on it to kind of rub a spot kind of dead dead nuts in the center this you won't be able to see it but this is a starting drill it's not really a drill but it's more like a trocar it has three flats on it that come to a point that's on center so we're gonna use that and basically it's gonna scrape a little Center right at the center of rotation and that's kind of key with working with small small tools and small drills like that now one nice thing about this kind of stuff is you don't really need a Chuck key because the forces are really low and it's gonna put it in there by hand like so okay I'll probably get a little closer and I'm gonna try to zoom in and get up on there so you guys can see what's going on as best I can so okay this looks pretty good from here [Music] there's the little hairlike drill try not to bump the camera here to disturb you guys and you're in your leisure I'm gonna choke up on that a little bit too high ridiculous it really should be spinning a lot faster than this but I get this big Chuck with a sub Chuck on it and I kind of don't want to spin it real fast so let's just try this [Music] you know what [Music] mr. Bose no didn't get the drill in there right it's really easy to do okay look right either all right you know what I gotta back this off I really choked up on it [Music] total sensitivity on this you totally feel what's going on really nice a total control we [Music] yeah he's got to get the drill when the dang Chuck straight and then as you see here there's a chips packing up and that anyway yeah let me see if I can find a smaller drill we'll see what we can do with a smaller drill all right I found some smaller drills so this drill here that we're looking at through the eyepiece of the tool makers microscope this is about 5,000 syn diameters so if I reference up there and then crank over to there I get about five thousands okay so I'm gonna try to show you one of these drills out in the air and you'll get a sense of just how small this is it looks looks actually like a really nice drill from here but when you look at them in person it's a little different okay so there it is in you know full-size this gives this probably gives you some sense of yeah let's do this let's run it over so those are 1/2 millimeter grads there I don't know if that helps or hurts I'm the big screen yeah she's probably better like that anyway there it is right there there's the tip so let's go try that and you know our little sensitive feed and see if we can snap that sucker off there's a picture of the setup we're gonna use I'm gonna get an indicator on here to kind of monitor you know the depth that we're going in there so this is just a starting drill here and then I'm gonna try to sneak up in here and get a little mark on there okay so the normal normal Sharpie doesn't fit so I'm gonna get a different sharpie yeah I don't think I quite have the center in there yet it's so I can see the the dot appear basically is why I'm marking it so anyway I'll get you an all on the tight shot and then we'll drill try to drill some holes okay so we got a marked kind of ready to go just for perspective there's a the size of a fine tip sharpie so this little diameter here that I turned down that's one millimeter 40,000 some diameter and we're going to drill into the end of that we we're gonna attempt to drill it to the end of that so I think we're ready to go here let's fire it up this is the starting girl so one I'm gonna switch over to the micro drill right so there's the supercalifragilistic teeny tiny drill let's see what happens I can barely see it myself I'm trying not to bump the camera and get my big head in there that's why I have so much I got a long stick out from the light here just so I can get at it so let's let's go for it thousand rpm here [Music] so that's already ten thousand sin I'm looking at it from the side I don't know what it looks like from the top because the cameras in the way I suppose they could what I can't watch the the screen on the camera and the indicator at the same time I can't quite do that I can't split my eyeballs like a chameleon let's say let's part that off and then well maybe I'll go a little further and I'll part it off and then we'll take a look at it under the microscope alright so I actually got a pretty good shot down the microscope this time so there's our hole that we just did and so there's our forty thousand Siam or the blue right across there you and then there's our little hole that we put in there so when I measure it with them with the microscope reticle and dials I get about seven thousands diameter which is a little bit oversized so there must have been a teeny bit of run out or the you know the drill wobble a little bit or something and then that let's see if I can change the focus a little bit so the edge of the hole is is down from the surface a little bit so if I change it's hard to look through the viewfinder here I can sharpen the edge of the hole a little bit depending it you know by changing the Z height of the microscope to focus on the edge of the hole so right now we're kind of focused on the surface of the blue and then if we go down a little bit there you go it sharpens up the edge of the hole a little bit so that's kind of what you're looking for anyway so that was drilled with a little hand-feed thing and I don't know kind of fine so you can do tiny tiny holes and there's a little guy right there and I don't know I don't have much more to say fun little project and thanks for watching guys catch you next time
