Leica MZ6 microscope and microscope stand

[Music] hey welcome back I want to show you this thing this is a Leica m6 microscope sterile microscope a very good friend you shoot me with this microscope because I was looking for a stereomicroscope Photoshop for a very very long time and couldn't find something that that really struck with me so he told me to just take this didn't came with a stand in fact the can withstand but the stand was a boom arm with about a meter length and just too bulky for my shop and also too flexible right away he told me that I had who would have to build something myself so I decided I designed this contraption here which is like a scholar aa robot with to swivel arms that can fold up into themself or almost into themselves like this go back into this this notch off my shelving up here and be almost out of the way or I can just pull it out to use it as you can see the eyepiece is very up high here but on this Leica this has the articulating head and I can just get it down to the right height so I can work without over straining my body I'm quite used to use sterile microscopes at verb we have them everywhere we have Aschenbach microscopes which are a bit cheaper very decent microscopes for general sharp cues they don't have soon they have fixed magnification this one has su we have twenty five times magnification up here on the eyepieces we have twelve point six three times magnification down here in a additional lens and the microscope body here goes from point six three times magnification up to four times magnification that an overall gives me a range of magnification from ten times at lowest setting up to sixty three times at the highest setting here that's a very good range ten times is great for doing manual work on the microscope soldering deburring and as you can see it's it's right now set to to a about 150 170 millimeters above my bench that's a good height to work under the microscope in your hands it has it has of course back here the focal adjusting stage which allows height adjustment and setting your focus it has very large travel the boom arm that I made already stand here is relatively Richard for how far it did reach it out this is 30 by 30 millimeter box tubing and the joints are welded on steel two rings poured out and then I have egos plastic bushings pressed in them and there is a hardened and ground bolt running in them and all its axially preloaded so this joint is super rigid and doesn't move on its own it's it has a little bit of drag same for this joint also egos plastic bushings in here was very nice and back here also you had your height adjustment does not finish yet I just have a shaft collar here where this arm drops down on to like this but general use you have not to adjourn to to move this very much for what I do this will probably stay in place now and right now it's just altered to a steel plate that I clamped to my bench I might probably change this at half the this arm here come from above so I do not have anything sitting on my bench good friend gave me that tutor mounted overhead it has a ring light fiber optic ring light so no LEDs in here it has the fibers coming out here and they and they terminate in this coupler here this the surface here that all the fibers coming from here through here coming out here and it's ground flat and normally you have a light source with bulb light bulb in a transformer that it gives the light for the ring light but I have that too it's still in the car it's very bulky very large it wasn't too happy with it so I figured a good lb flashlight would do the same I bought a inexpensive lb flashlight rechargeable off eBay I removed the front ring here which has a fine thread i machined an adapter of Delrin that screws on here and as a press fit or a very tight sliding fit for the coupler and I have my I have my ring light here lighting up it's just hold on with three regular screws just like this and here you can see all this here are individual fibers fiber optic optic fibers gas fibers coming out and it's it's ground flat on the end and that's where the light comes out and this is this is just spooky cool and I have to to brightnesses flash mode because it's a tactical flashlight and off also I can set it to SOS if I ever get lost with my ship because they cannot sell a normal flashlight anymore that has just on and off so this goes on here just clamped in place and you're good to go burn nice microscope really I would not have bought this microscope this is way above my price leak and I'm really grateful that I got it it's really a beautiful instrument and I'm very happy to have it here in the shop I well I would try to get you some some pictures through the eyepiece and look at some things okay I brought the camera up to the eyepiece and I try to get it and focus it's not very easy what you're looking right now is a ten millimeter through carbide end mill at ten times magnification as you can see it's it's a little bit chipped here here and the thatch - and we can look at the flute the cutting fluids they still look quite decent this one is a little bit chipped here right in the center of our the crosshairs here it's chipped and that way you can look at cutting tools work pieces very very closely and decide if they are good you can see tiny burrs or parts you can do work on the microscope you can use tiny stones or files or scrapers to deeper parts and that that's really nice here is a that's a point eight millimeter and mill ball end mil and as you can see we don't see much it's very tiny so let's let's increase the magnification not there we go that's my dirty finger there we go that's that's the ball end mil and this this guy has seen better times to the the dirty lines in the background that's my finger that's the lines of my finger you can see no that's terrible without support that's uh that's that's the tip of ballpoint pen and see that this side of the cutting fluids is not very good anymore it looks a little bit chipped I can't tell very good because I'm looking at the viewfinder of the camera but you get the idea there's a pretty horrendous ball end mil here doesn't look very good anymore this is these are the cutting edges off one of my dull eight millimeter six blue carbide end mills here you can see one after cutting edge chipped it's chipped here and it's a little bit I just like I used it in a trip State because here it's a braided then the shiny surface is braided and the matte surface here that's just chipped away carbide same here in fact that I butchered all the cutting edges on this end mill almost oops yes that's 50 bucks and mill there I do not have a full build video on this stand when I built it it I did a CAD model that I can show you and I have a bunch of photos off the build process and I will do a little bit of a slideshow to show you that okay this is a quick view at the cap model I'm currently testing the Libre to sign our expert because I do not want to use fusions 360s my mainecat system because it stores that data not locally on my computer but it stores it on somebody's ass computer and up that's not set before me so if my main cat I'm looking for something that stores the files locally has no subscription model and is mine so and as far as I can tell I really like a leaper designer it's reasonably priced has a you buy a license and you own it then you can buy updates or to a maintance fee but that's not topic of this this is the the microscope stand and cat with the two arms here and here and doesn't front here this yellow piece this is the height adjustable focus stage of the microscope that came with it this goes into the end of this arm the joints let's hide the arms the joints consist of these gray now yellow highlighted bushings these are Aegis low friction plastic bearings which have excellent wear properties and the pin in the center is pin the yellow pin this is a piece of hardened and ground shafting material and all is held together by these two yellow highlighted washers and they I ground a surface ground the pin in here about 0.1 millimeter shorter than the measured distance from bushing top to pushing bottom so when the screws are tightened and the walkers are pulled tight against the the joint everything is preloaded a little bit axellian that gives a very nice drag on the joint it did the same over here on the microscope holder or on the microscopes cage see these two yellow pieces again are the eBoost bushings and down here is the washer again that preloads against the bearings and on verge EFT it's just sliding with two with these two bearings and the arm rests on top of a shaft collar which is not modeled here and here is the drawing that goes along with the microscopes can't not very complicated just I have something to work off in the shopping do not have to call up this really model all the time which is quite annoying the drawing the drawing environment here in a Libra is real nice allows a lot more options than a fusion 360 and fusion 360 the the drawing compartment seems like an after salt maybe because it's not a sexy-ass generative design or five axis machining but in my mind that's a mistake you always need a proper 2d drawing if you make stuff okay let's see how this indicator stand was made it all starts with some t om tubing and some Serge by 30 box tubing kept to length the square tearing is notched out with a hole saw to receive the do M tubing in the ends everything is cleaned and chamfered with flat wheel and a carbide burr so the TIG welding goes well over everything's clamped down with different clamps on a miniature welding table for tack welding and for actual TIG welding it completes the all-around the finished arms after welding the welds are not too pretty boring out the the arms to final dimension so they're a nice press fit for the eCos plastic bearings here are the plastic bearings already pressed in and the lathe parts are done the the bolt and the washers are finished and here microscope stand is basically assembled it just needs some white paint for all the welded pieces or white powder coat but público Dena's problem now as the bearings already pressed in so I'll probably just hit it with white paint that's the Leica M c6 microscope with the stand you will just see this used in future a lot more I hope that Kent and I can get a camera adapter so when not in use of course it's covered up so it doesn't get dusty or oily or something like that and then push back into this corner like this hope you enjoyed thank you all for watching and see you next time
