G0704 Improvements Project

good evening I've been a while since I've made a YouTube anyway tonight I want to show you some of the things I've done with my 704 mill a lot of these things you can do with any mail but there's some improvements that I made a made a lot easier for me to get some work done and and certainly a lot easier to get a lot of accuracy now that grisly 704 I've got here G 0 704 it's a variable speed and it came the little z-axis digital readout here that would the worked fine it was a I sure pleasure to use however it wasn't very bright so I decided to put a dro on this thing and I swapped that unit out this grisly when I came with was an eye gauging his setup allowed me to put I put the z-axis in first and then it it comes with an alarm like that and I added the X and y-axis and boy it changes a lot of things that I can do was my mill that I wasn't able to do before I'm after using this thing for a couple of months I don't look at it as a as a luxury it's his damn near necessity and I could have spent $1,200 for a magnetic scale you know dro pro model look like I've got on my lathe but this what I've got about 150 dollars in and as far as actually concerned I just created it allows me to work down to a thousands or lessened in any axis so I'm quite pleased with it you got to take a little imagination to to get it set up an atom well I well I was Anton I had to take my mice wolf guard off and I'm sure a lot of you that got mill drills on that I've got these little accordion types for cards back there and there are adequate but I didn't care for it so I what I did was when I finished up put another dro on I made a point I hope you see that down here I got some rubber material is a speech 24 by 36 it's actually a a cushion pad but it's been very durable and I cut that six inches wide by by about 24 inches long and rather than an accordion thing this thing covers my my the opening you through my column and and base and there's a very good job of keeping its Wharf out of there and I just used the hardware that was holding the accordion style thing on there now I've got this one piece and if it ever wears out it was very cheap like I think I paid $12 for 24 36 inch piece so I've got enough for about five more replacements here if that whatever wears out the other thing I did with this mill is I upgraded to a what I think is a very good advice I've been shopping around I know a lot of you probably looked at them and you know you're looking at $600 or thereabouts for a good 5 or 6 inch of ice on a mill this size I was using a 4 a 4 a 4 inch Palmgren which served me pretty well but it was repeatability was a problem and and even though it helped apart in pretty good sometimes it climb out well I came across this $300 Chuck I think it's probably made in China but maybe India and they assured me char's they assured me that this thing would hold five ten thousand or better and I thought well for $300 I call try it out and I've been real pleased with it I'm mounted on the on a lathe it's a it's just right for my working bloke here being a five inch it's a little heavier than my than my other one I did not like to handle I came with it so I I made my own speed speed range for it I like to style a ranch now one of the big benefits I did some other things I made a I made a collar to go around the the unmovable spindle here with a with a variable speed mill that's not a gearhead when you want to tram in your things like traveling your vise and stuff it's hard to get something so I've made a little collar here to hold my my no go arm and an indicator for Kremlin net and that so I've got this mill crammed and I took a little while but it's rammed into less than a ten thousandths on the left to right x and y or x axis and I had about three ten thousandths of nod towards towards me well I got a breaker bar and a ten millimeter wrench to it and I the the the bolts on the back of the column are tight I got him to move just a just a smidgen I think my nod now is right about it ten thousands well I thought that's by anybody's book that's good I got device locked in there good and so crammed in good so I can do some pretty good work now one of the benefits of having this Dro one of the big benefits is is that I can create a I can position holes by using coordinates and I've got some software it's a there's lots of available out there that'll going your computer your tablet or your phone I'm using a thing called the machinist calculator and for example here I've got a block that I wanted to put a holes in all four corners equally spaced so I described this software I described this is a four by four by 1/2 inch thick block and so I described a a the center of it as a y 0 X 0 and then my first hole would be at 45 degrees which would put it up here in this corner and I wanted a four inch I wanted these on a four inch circle which placed them right out here in the the four corners of course at 45 degrees put me out here split the difference between 12 o'clock and 3 o'clock put me right out here at the corner the man it's so nice because I run that program I've printed it out I doubt if you can see this very well but it gives me the coordinates to all four holes X I run X to 1.4142 then Y to one point four one two and then to drill that hole go the next one would be minus y or minus X and plus y same measurement but anyway it gave me the coordinates of all four holes if I want to do three holes or twelve volts or 37 holes it would give me all those coordinates you just followed over there and and it makes it really nice you just find the center of your block that's the reference point now the other things that I did was this as I added a power feet nose I've had in the past always had a power feet I didn't have one on this believe me if you don't have a power feed you can you can get by without it but gosh it's it's so much nicer if you do have it in my opinion yeah it's easier to get a good finish it's a lot less tiresome but the finish is improved quite a bit now let's see here I got the Dro oh and the idea that I the drawbar that came with this had a little bitty thing they just took a little a little six millimeter wrench so I've got I got some some 11:44 stress proof steel that's really good stuff for that so I built my own drawbar with a with a hex nut here that takes a half-inch sock at the top and it spins real true the one that came with this had a little bit of wobble up here which it didn't hurt anybody just kind of distract me I didn't like it so I made a drawbar that was pretty simple to do well I I'm going to call us good for the night I'm going to go into the next video or the next video I'm gonna cover what I'm going to do is this block that I've got in here and I thank you all very much and have a good evening thank you
