Harley Davidson Pan Head Engine Case Repair Part 2

[Music] very first project on the victor in this new location over here in the corner I found a piece of one and 3/16 stress proof material this is free machining and it's it's good strong material so it's easy to cut we're going to use a three jaw Chuck will drill our hole that'll be our clearance hole for a quarter-inch bolt now in the middle and then we'll turn it as needed and part it off and then what we'll do is we'll set it back up and I'll do the counterbore for the bushing that's supposed to fit inside of it you use a high-speed tool bit so I'm going to use my Armstrong holder and I went ahead and I ground up a fresh turning tool just a general purpose turning tool bit out of the piece of Rex 95 and we'll give this a try and we'll start start using that it sticks out more than what I would like to but I hate cutting us off unless I need so I'm just going to go with it for light duty turning like this it's going to be good there we go just adjust in the center you might be wondering how you can accurately measure those counter boards down in there now one way you could do it is if you had some pin gauges those are excellent for jobs like that all right I've got another way since I don't have any pin gauges that go up to one inch I'm going to be using my steric number 700 this is 200 to one it 200 thousands to one inch so it was like a zero to one inch mic this was my granddad's matter of fact it's his initials right there so we're going to use this now I've already verified these you can go with another one-inch mic that you know is on size and you can verify the outside and you use these just like you would like a veneer caliper try to get it out of here without bumping it so it looks like we've got it's gonna be that's 759 759 thousands and then we'll let me move out and then we'll check it with the other micrometer all right so I'm gonna take my zero to one and we're gonna go ahead and check it there it feels like it right there so it looks like there could be two maybe three tenths difference total no we got our measurements I'll go ahead and get back on turning this so we're at 980 but I'm gonna have to go ahead and turn this area down some before I can get my mic in there to measure this little area accurately we're at 980 we're gonna take two more cuts [Applause] [Applause] so I'll go ahead and get this larger-diameter finished out we're going to finish it at 9:18 [Music] let's see if I hit my target nine 18 and a half so that's perfect it won't take but just a touch with either a file or some memory and that'll take that right where I want it okay I'm at 765 take four and a half thousand on the dial and let's hope that I'm there come up to our zero okay go in mm on the face face it back and hopefully that's going to be our diameters to give us a slight interference fit in the hole okay there we go seven sixty seven sixty and a half just walked out our tool bit there for a chamfer and tool and we want to break those corners we're going to use that quarter-inch stubby drill there to drill our hole it is a trying to find it sooner there it is a quarter-inch bolt that goes through it alright so we're going to we're going to give it some clearance with a 281 drill so you guys probably wondering why I'm not using any cutting oil a lot of times on this stress proof you know for this small a bit of work that we're doing cutting oil really isn't necessary I mean you can it's going to help it cut a little better but stress proof is a pretty free machining material and for the most part it does pretty good so really no need for cutting wall you can defer those holes with your Noga that's all it takes so we're going to go ahead and part that thing off I've got it polished down to our sizes that we want I want to point out I'm using a high speed steel tool parting blade there it's 1/8 wide miking it is actually put 1 to 8 inches wide so I touched off on the very end of it and we moved it down 378 thousandths and that should give us our our finished parting link there so parting usually wants oil whenever you do that so we are going to use a little bit of cutting oil on that and I do have an angle ground on the end of that blade now we're just gonna go in a bit I'm gonna back you out and go ahead and buy all that sharp corner off go get your rod in there there it is so we're not done yet we've still got to chuck this back up and we're gonna come in on this side and counterbore it for our pin that fits in there alright there's our bushing there this is our pin that's gonna fit in it like that so I need to counterbore it we're gonna count aboard 3/16 deep up to this size and what's surprising me this is 14 millimeter it's just it's an old Harley engine so I don't know why this would be 14 millimeter but that's what it is so but miking it with the mic what we're going to do is we're going to finish this bore at 0.5 v 5 and that should give it about a half doubt clearance to go down in there alright so I've got the Hardin's collet Chuck set up with a 3/4 collet and this will fit make sure there's no fuzz on it right there get rid of them burrs and I'm using a very small boring bar but this will allow me to get up in that quarter inch hole and do our little counter bore so hopefully it'll work pretty good here alright let's get going that's enough on our face and I'm going to set the dial here 50,000th and it works so let's do another 50 did you see it bend down that's okay if I needed to I could go in there right now I have some small carbide insert bars but none of them were small enough going 1/4 inch hole but that's gonna give us what we need right there take another 50 all right I'm going to get my mics I'm going to start doing some measuring I'm going to use my general telescoping gauge this one is under I believe it's quarter to two half-inch now in the past I've had a lot of people comment on how you're supposed to get an accurate measurement with these things with a square end when in fact they're not square and their radius they're radiused properly so that you can get your minimum diameter that you need just stick it in there snug it up push it down and then mic over it I like to rock it back and forth so that it's touching and that puts this set for 84-83 okay so we got a little bit to go should be getting down to my finished cut right here I've been sneaking up on it I should have about six thousand sigh believed to come out of this thing five and a half so I'm gonna go for it because I just split the cut I just took five thousands and I am using some cutting oil now go ahead and touch the face mm so this is a good job for ping gauges and I have pin gauges from 1/16 to 1/4 I'm sorry from some 1/16 to 1/2 and then I do have a set that goes like from 3/4 7/8 but you can use those pin gauges that are like in 1,000 chram it's to check holes like this you know instead of using telescope gauges or micrometer so it looks like right where I want it a few tents under I'm gonna double check it so I can probably stick some memory in there and polish it out of there yeah I'm like right on it right on it instead of risking cutting it too big probably just go ahead and polish it out of there now that may not do it we're gonna give it a shot and see and I think that did do it it's a really close fit though oh yeah it's super close it's trying to go in there you see I'm wiggling it so that's definitely where we need to be but I don't want to get it locked in there so see that we're gonna go ahead and pop it out of there and we're gonna leave that fit right where it's at before I attempt to press the bushing in there I'm gonna use this Noga straight bladed scraper right here and try to very very gently go in there and lightly deburr that edge where the bushing needs to start in there so that it's not a sharp edge all right so I'm gonna have to move the camera butt up I wanted to do just enough to kind of show you just like that I'm gonna have to kind of come around like that get in the way but that's what we're gonna use right there I'm gonna give a little shot my solvent cleaner right here just to make sure everything is clean and this stuff dries pretty fast as well [Music] yeah I'm going to do the same thing to the bushing we'll spray it a little bit make sure it's good and clean as well all right we're gonna go ahead and get it in there so I'm going to use just a little bit of my 680 Loctite this is good stuff right here just want a little bit pardon my hand all right I think that's it now here it is all right it's going down in there I can feel it all right that's gonna work so you can pull that in there with the screw or bump it in there whatever he wants to do and we're gonna leave it we're gonna leave it about like that I just got it started in there I'm gonna see if the the cover plate will line up on it now all right here's our cover plate and let's see you fit a line up look at that it's in it looks like we have success alright man very nice I'll see if I can get that back off there we go okay there we go alright one last thing I'm going to do I want to go get my debt mic and measure from here down to that face and see how close I am to what I had measured the original face up so when I took the original measurement it was almost like that surface was slightly sloped so when I took it I took it like in the best place that I could to split the difference and I was getting one point two inches one point two zero zero that's what I wrote down so let's see what I'm getting now I'm getting 204 so I'm actually for thousands deeper than what I had originally miked that at all right guys we got another one done and I believe it was the complete success and I'm happy with the way it turned out everything lined up I didn't have any problems everything went my way so I'm glad to get this one done because I wanted to get this one finished up so that I can get back on to my Schaeffer project I got some Parts I want to get started on for that but good little project for the channel they're showing you some different techniques on the middle and the lathe you know and another reason why it pays to have an assortment of different tools you know around the shop this is why you have many different types of measuring tools it's not necessarily you know this isn't something that you would use every day but there's there comes a time when you actually need a tool like this to do a certain measurement you know so it's good to have that kind of stuff but there we go I'm gonna sign off and let them know this is done and I hope you guys enjoyed watching this video and it was good to get another project done in the shops been a little while and I look forward to continuing to do that for you here on the channel alright see you guys next time [Music]
