Walker Turner Drilling Head Adaptor Part 2: Rotary Table Machining & Finishing

[Music] [Music] all right so we're all set up and ready to start our mill in here i'm going to be using my rotary table for this op and uh once we set it on the table i went ahead and indicated the center of the face plate there and then i mounted up this three jaw chuck this is a low-profile chuck used for miller machines things like this and i've got a piece that i chuck in here and i indicate the center of that so our chuck is indicated center all this is centered up with the spindle and this is a universal circular dividing head or uvt universal vice and tool company it's a extremely high quality there's another tag on the other side that says tempkin bearing equipped and it's always been a fine tool so we're gonna go ahead and get our part set in here and tighten down and i'll just go ahead and go around to all three of the pinions on the chuck here make sure it's equally tightened up i've already got zero located right here and then on the the uh hand dial here you've got the minutes so we've got the minute set to zero and i've got this pointer set to zero so that's where we'll be able to start right there and we'll go ahead and start with our our holes first after we get our holes in there we'll move on to the milling of the slots first part we'll go ahead and get our holes in there here's another look at what it looks like so we've got two drilled holes these are just for a half inch socket head bolts right there so they're going to be drilled and then countersunk for the for the socket head to go in then we've also got two holes that's going to be drilled and reamed these are for alignment pins you can see them right there so i've got some new pins that we'll press in once we get through with the job there so get the four holes the two counter boards done and then we'll move on to the slots for our whole pattern we're just going to use the dro since we're centered up on there and it's a you know a simple xy movement on those without too much fuss four and five eighths is the center to center so we're moving two point three twelve that'll be uh halfway right there we'll just go ahead and spot them with the spotting drill first and i've still got that set too high so let me pack that down all right there we go all right let me just move across to the other side and get it done 33 64 drill and no worry of crashing in the jaw because we've got that slot machined in there on the back side of face groove [Music] all right getting ready to do our counterbore that's a 13 16 end mill that we're going to use to create that counter bore that'll give it clearance for the socket head and then the depth is 3 8 and the the bolts that go in there i believe they're the heads are a little bit narrow all right we've got the uh the feed set at zero and i'm just going to count it going up i've got a stop set on the spindle or the quill up here so on the other side we can just kind of come down with it like we would like a drill bit [Music] all right there we go so let's go ahead and get our two pin holes put in there we're gonna we're gonna spot it with this drill here and then what i'm going to do is use a letter c drill bit this will drill the hole right around 242 thousandths in diameter and then i have a .249 reamer that we're going to use to ream the hole and that should give it uh the proper press fit for the pen that's going to go in there just double check we're at uh 1.687 and three eighths is our center to center distance so split that in half using our x-axis there just center it good with that drill this is more of a you know a stubby drill these work good for spotting them in and we've got a brand new letter c size drill bit here that we'll use so all right we'll just move down and do the other same way we've got our 249 reamer in there let's just ream a little bit of the hole there because the pin actually presses in to the other side and it's quite thick right there where that pin is going through so let's just kind of test it we'll ream it a little ways and then see if the pin is actually loose or if it's tight all right it feels like it's tight so we should have an adequate press fit on this uh on this pin i wanted it so that it did have an interference fit and it would press in there and they would they would keep okay go ahead with our riemann now just as easy as that double check it one more time we should be good to go on that go ahead and move it down to our next hole [Music] all right so we're gonna go ahead and move on to the slots but the first thing we're going to do i'm going to put uh four holes in there which will be the ends of the slots right there we're using a 31-64 drill bit i'll go ahead and just uh drill a hole where all four of the slots in and it's on the same circular pattern as the uh the two bolt pattern right here which is uh four and five eight so that's where we're at so we've got the xy table locked i'm verified on my dro up here and we're zero here and zero here and so we're going to go ahead and rotate it around and i've got i got my notes up here so that i can quickly look at it and i don't have to keep thinking about what position i'm supposed to be on but i've got a little note you know i start at 40 degrees so each each slot is going to be 40 degrees off of this center hole pattern right there and it's a total of 100 degrees sweep all the way through there so i just got a little note up here saying that go to 40 and then from 40 we're gonna rotate it around to 140. from 140 we'll move it around to 220 and then from 220 around to 320 degrees okay i hope that makes sense i've just got it laid out the way that makes sense to me the easiest to understand and we're going to be rotating clockwise come around to 40 and as i see 40 approach i come up here to the zero on the hand wheel just like that right there and we'll go ahead and just snug one of those up so that is good i've verified everything so there shouldn't be any mistakes right here that's being made go ahead and give it a give it a drill this will provide a clearance hole for the cutter to go down in whenever i get ready to mill the slots i've got the camera right here on the side where you try to use a quill handle all right we'll go ahead and loosen it up and we'll keep rotating it around here to 140. 140 and i'm watching my zero to come up right here line up with the hash mark and we're good to go just going to do a replay on what we just did right here 40 degrees zero here and we're taking it to 140 and then we're watching for the zero to come up and line up with the hash mark there right there and we'll drill a hole all right we want 140 we want to go to 220 now and from 220 to 320. 20 all right our last hole there's our four holes right there so i'm going to go ahead and we're going to bring it on back around here to our start which would be 40 degrees and we'll set our end mill up let's see we got a couple more there we go 40. and we'll get our cutter set up and start our milling all right it's time to get the mill and the slots on this thing and this is a this is a procedure that always makes me a little bit nervous you know moving this uh table around and making sure you don't go too far and cut a little bit far into one side or not but uh i'm gonna go ahead and focus on getting it cut i've got abby out here helping me get some of the filming done she's gonna give me a hand so let's get started on it i want to i want to do a touch off we're going to be using the uh the tongue force wreck half inch diameter insert mill to do this job i think it's going to do really good but i've got to cut it in stages i can't cut it all in one depth so we're going to be making a total of three depth passes through this thing 200 000 each pass so once i get the depth set we'll go ahead and set a zero and get started on it so here we go i'm running full speed this thing's got 27 20. [Music] all right zero right there i'm going to go ahead and back it up to uh our starting point right here 40 degrees zero [Music] and here we go clockwise well that ain't good our light fell there's a lot of vibration going on right there so apologize about that let me go get a wrench and tighten that up a little bit [Music] did you get your chip on i sure did they're swinging they're hot right on the skin that's my first chip i think sorry about that the camera is like very shaky they land on my arm too this would be a good time to actually do you know have some long sleeves on so that they're not burning my hand up yeah i did not choose the best shoes for this help that's my fault we'll let it slide this time sorry all right so i've got my flannel on just because these chips keep hitting my arm and burning them so this is that's the only reason i got my flannel on and uh abby went and put her on her osha approved safety toe boots so i think we're ready to go i'm going to continue my rotation around to this side that way i can establish the same depth for each cut okay i'm just going to back it off and i know i'm going to go up to zero there and we want 220 here yep [Music] [Music] [Music] go back around or i start 40 degrees right here [Laughter] everything's looking good to our next start point 220 right there [Music] [Music] [Applause] food [Music] all right it's looking good all right our first two passes look pretty good so we got one more to make to clear the bottom of that so now we'll be going up 600 thousandths zero one two three four five and [Music] six [Music] [Music] zero [Music] [Applause] [Music] all right we got we've got it cut in there now let me show you my one little bozo i already screwed up i didn't have the tool all the way up clearing the part and you can see when i started rotating it around here i just started skimming that so that's what i'm talking about it's real easy to screw up when you're manually doing this on the rotary table we got her done our half inch insert mill did an excellent job milling that slot right there you can't even tell the thing has been used it really did a good job now however the slot actually needs to be 5 16. i knew this going into it but i wanted to use this to you know machine the bulk of the uh the material out now i could there's a couple ways to do this we've got a 9 16 10 mil and we've also got this guy we just used but to use this i would actually need to do an offset on both sides of the slot and then of course do it three times again because i can't cut the whole thing with that that's not you know the inserts are not tall enough to cut the whole thing so to keep from doing that on both sides i think i just want to go in with the 9 16 end mill and use that to relieve the slot that we need hopefully this will do a good job i'll slow it down for this to slow down the speed and we'll go down there and mill the slide out let's go let's go see if we can get it done so what i'm doing is i'm relieving both of the ends with the cutter first so that whenever you come into the end you're not having to cut the full radius there 20. i am running 660 rpm now that's uh right at 100 surface feet per minute and we want 320 on the dial here we'll come back around to our 40 position and see how this does i'm going to try to cut it it might be too much to cut it at once i'm going to give it a shot and see what it does i don't think i'm going to do the full depth there because that's that's quite a bit we're going to go half of that 300 thousands right there [Music] definitely trying to be a little grabby on both sides there so i'm giving it a little resistance with the lock here just trying to keep my movement smooth it seems to be working fine all right for our 140 one two three all right work pretty good so we're down far enough and we'll go on around for 220. 120 right here seems to work better whenever i'm holding it like this it keeps trying to grab it me work good one more pass we'll have that slot finished up one two three four five six that should be clear should be good to go all right we've got a slot there foreign there's a better look at it i'm going to go ahead and just do a very light chamfer on these holes we use this noga tool right here always works really good i'm gonna do a little deburr on the slots now still got that little sharp edge sticking up from the milling so we'll use this guy right here i got the specific blade i believe this is the st 101 tip doing the inside one is a little bit more tricky there it really helps whenever you're actually pulling against the material there so we may just go a different route for the inside [Applause] so okay so our last step for this is to install our two pins you can see those here on the old piece quarter inch dial pins and they're sticking up 3 16 of an inch so i pulled out a couple of these from my rotary bin right here a couple of quarter inch dial pins i cleaned them up they had a little bit of a little bit of rust on them so we got those clean so what i decided to do is i took two pieces where i cut me two pieces of 3 16 square stock and we'll set them down on there around the hole like that and i'll get the uh we'll get the dial pin started like so okay we'll go ahead and get it started [Music] started like that and we'll put those pieces of square stock next to it and we'll go to the dake arbor press and we'll actually just press those down in there and then the of course the square stock will keep it spaced out just like it should go ahead and get this one started in there go ahead and get this thing dusted off just a little bit i'm just gonna go ahead and lay a fresh towel right on top of it just to kind of prevent any kind of scratches in the work piece here all right there's the first one pressed in one last thing that i just about forgot i went ahead and put my mark in there and i did it twice the first one i didn't get it very good you can see there only got about half of the a-bomb in there so i did it one more time on the opposite side that one came in a little bit better you see it right there so now the job is complete all right guys well there we have it this piece is all finished up it is done and it is ready to go go back up there to tab i'm real happy with how everything came out all of our sizing is spot on all of our finishes look good just it all worked out really well for me it's a good looking part and i'm excited to be able to provide this to tab so he can put it back on his walker turner ready to alarm drill press so uh be sure to check him out crosscut vintage designs over on instagram uh i don't think he does youtube but he's pretty active on instagram sharing his woodworking you know his furniture making does a lot of really high-end quality uh woodworking furniture making type of work there so i'm sure in the future he'll probably share some some pictures or something of this walker turner drill press as he puts it back together and i'll ask him if he can uh you know later on as he gets back on this project maybe he can shoot a couple pictures to me or maybe even a little video of the thing running what it looks like back together and i'll share it with you guys you know like a kind of like a progress report later on but i'm sure he's going to be happy to have this and it's going to be a good part to go back on the machine and just remember you know the only reason it broke is because it accidentally fell and hit the floor and cracked i had a couple folks ask well why not make this out of steel or something stronger to keep it from breaking this cast iron as ductile iron is perfectly suitable for what the part is it's just not made to take an impact like it did when it hit the floor so i like machining cast iron and duct ductile iron myself i know a lot of folks don't they think that it's too dusty and i think it machines really well i like it myself so i'm going to get this thing oiled down we'll probably use some of the crc sp350 rust inhibitor to keep it well oiled i'll wrap it up and we'll get it sent back up there to tab i'm sure he's gonna be happy to have it back so he can start working on his machine so there we go i enjoyed sharing this with you some fun rotary table work there with the radial slots and uh hopefully you enjoyed watching come on back for some more and hopefully we'll see you on the next [Music] project [Music] [Music] [Music] you
