The Ultimate Round Column Mill Fix

[Music] hey thanks for joining me hell this is it this is my round calling metal fix that's what we're going to build today many of you own a round column mill you know the frustration of uh drilling a hole or milling a slot or whatever and you go to put a longer mill or drill in there and you can't fit it so you undo your lock down on your column and raise it up and you no longer have your horizontal position a regular mill has a table on the bottom an email the table moves straight up and down and you don't have that problem so i've come up with a cure for the round column middle power left power left it stays lined up anyway let's get on with it and build this thing okay primary objective here is to stop the mill from moving like that when you raise it up and down i was going to put a clamp on this column and mount a bar right here maybe another clamp right here and have a guide that follows this bar when you raise it up and down but this pulley hits this bracket here you got the coil handles here that are in obstruction and you have the lock down here it would be harder to get to if you had this bar here not impossible just more difficult this is the main thing right here let me show you the other side okay everything's clear on this side you don't have any pulley here you can mount that bar right there the pulley won't obstruct with the bracket uh same on the bottom but you got this handle here just for the height adjustment got to be able to get to that so what i'm thinking now is put a power feed right here uh that's fairly slim and then my bracket right here the power feed will be really nice anyway so that's the direction i'm heading now but i've got to build a clamp to clamp onto this column so it'll be a section sticking out like that to mount the bar to that's what i'm working on now okay on the top half of the mill here i'm going to make a u-bolt go around it like that and then i'm going to cut a piece of metal like that to go on to that u-bolt like that and that's what's going to be my clamp up here so right now i'm cutting that curve and the bottom one i'll have to mill a slot in for this uh rack anyway that's what i'm doing now okay to cut that curve i could have used something like this but i didn't have one large enough uh so i made one and i'm not going to get into how i made that most of you will probably just buy a fly cutter that's appropriate or maybe you have one already this one here has got a carbide insert and i'm hoping it'll do okay okay as you can see i've already started cutting one piece right there and then i decided i needed to stack them and cut them both together so what i'm going to do now is finish cutting that bottom piece to match the top one and then i'll start cutting them together okay this is the final time okay we want to space these holes out from the center so the distance between the holes needs to be the diameter plus 5 16 which is the diameter of our our rod there so all total i need to make this whole spacing 4.84 that's center to center 4.84 but i'm gonna make that from the center so it's two 2.42 2.42 yeah so i need to go that's half inch so i need to go 250 in one two 50 is right there the center now i need to go 242 two inches and forty two so that's one two three so so yeah i like it okay this is how i made the last u-bolt this right here is three and three quarters and this is the same as my column i can't believe i had a piece that diameter it's four and a half it's not exactly right but it compensates for most the spring back move the camera a little bit well this one seems a little bit tougher than the last one i've been by golly it looks pretty darn close close enough okay i'm gonna cut the slot for the uh rack on the column and i'm just gonna eyeball it i'm gonna make it an inch wide and that's about an eighth inch oversized so let's go about 8 hd [Music] that's what i wanted okay eventually i'll be welding an arm to that bracket right there maybe offset a little bit i don't really know and i don't know the length yet until i get the drive on the power lift so the power left is the next step okay here's what how i'm going to do this i've got a plate here i've got it marked off as a hole for the crank this hole's right there those analog screws i'm going to mount that plate right there big sprocket to go there a little sprocket here for the drive and well we'll see okay i'm going to try to use a hole saw and this is a cheap little hole saw i got somewhere i don't know i've cut holes like this before with a hole saw and it did good that they were high quality holes those and i got this one surplus somewhere we'll find out that's my next project put make this uh metal a little bit about higher that's it i like it that worked good aha looks good okay the next step is to make some spacers to go in here this is not a machine service and i want to bolt it flat so hopefully the bottom of these holes is equal distances i'm going to make the spacer probably a half inch deep in that diameter there which i think is a quarter [Music] so huh look at that what do they do that for that's crazy looks like it's in pretty good shape there we go now tell me something why is this quarter 20 screws that doesn't make any sense this is a chinese made mill with quarter 20 screws i saw 5 16 in this mill too anyway that'd be kind of tricky i'll take this back off again anyway but [Music] [Music] okay the length on these is not super critical as long as they're both exactly the same okay i'll probably end up moving that gear or flipping it over or whatever but for now i'm just going to leave it there chain drive i think it's gonna work [Music] so of course it falls right between two links i may have to order a half light drum roll please ah i believe it's going to work good after i get a well maybe i need to put a chain tensioner in there put it right there i got a tensioner okay i'm gonna take this apart off camera and probably mill this off right here because i got a wire pinched right here and then we'll get back to uh my mounting the guide rod [Music] okay that right there is a bracket for our guide rail okay let's put this thing back together i gave it a coat of silver paint or hammered effect thing okay okay got the shop cleaned up i got myself cleaned up got a haircut let's finish up this guide rail uh bracket goes right there yeah figure right there now i've got to remove these and weld that bracket to it i think centered is pretty yeah centered over okay right here where i left uh where i welded this angle iron on i left a little ledge there i wish i'd left a little bit more but i wanted i wasn't sure what the clearance for my chain would be and uh turns out it's got plenty of clearance if i dropped it down another eighth inch would have been ideal but anyway angler is going to go in right there and that's going to be an adjustment i'm going to cut a slot in there for my guide and i'll probably put some delrin in here or something some kind of wear surface for the head to slide on the bar anyway i'm in the middle of that slot right now [Music] [Music] so there we go i could put steel on steel there or i could put some pads in there i think i'll put some like delrin pads in there yeah i think that'll work okay i added one final touch and then we can test how this thing does i'm sure it'll do fine i just don't know how repeatable it'll be how accurate it'll be okay what i did here i added that bar i i put it in there to get the drill up out of the way wow wouldn't you know it there we go okay it's all done the question is will it move at all when i lock it down i can tell right now i need to tighten these up a little bit i'm going to do that and then we're going to check the accuracy okay found a problem it's not a serious one but it's definitely a problem i put this clamp right here guide and clamp and i thought this would clear the sprocket comes down on this bar now i lose a half inch of travel due to the clamp on the column but i'm it's more like right there is touching it's almost touching this bar what i'll probably do is just put a shim right there so it never gets down to that i don't want to take take away from my downward travel but we're just talking you know 16 of an inch okay how much did i lose in travel i can't stay up there let me get something to stand on i lost about a half inch of travel on upward travel not too bad i could take off that uh or notch that guard and get it all back but i'm okay with that okay i've got the head of the mill locked down and set at zero okay now i'm going to unlock the head and it's fairly low now i'm going to i got the quill all the way extended and i'm measuring the quill as i raise it wrong way now i'm going to lock it down about one thousands one thousands off let's see if see if i can do that again [Music] okay locked down again about one or two thousands see which way does that need to go so you know what i'm gonna leave that i am tickled to death with two thousands unlocked move down lock it it's actually closer to about one thousands i'm tickled to death of that i like it well that about wraps it up for today that's a pretty good fix for a round column mill if you ask me fairly accurate really honestly more accurate than i thought it would be anyway thanks for watching and be sure and subscribe also one more thing i'll make the plans available in the information box i'll put a link down there to the plans and a parts list i don't have it drawn yet so if you don't see it there be sure and check back anyway thanks for joining me and be sure to subscribe you
