Quick Change Tool Post Mod // Beginner Lathe Project

In this video you're going to see how I take a regular import quick change tool pose and convert it so that I can fit it on a my furred lathe you can see that that boss on that compound is really strange and odd so sit back and enjoy I don't want to speak too soon of the self machine really nice but if I break this board most reach my limit here I don't think I'll be able to cut all the way through but it doesn't matter because that side is going to get drilled out so I make take it as far as a can and just cut it off for the hacksaw so for this piece we've got a half inch hole that's going to be drilled all the way through and then I need to open up this section here to an inch and a quarter well it's moment of truth here find out this does not need to seat all the way at the bottom here so when you see me put this on you might be thinking oh look you didn't make it fit but it does I have let me look at the sheet 515 thousands worth of space there at the bottom where this makes contact and I have measured it and it fits just fine it goes past a five hundred fifteen thousand so it will actually be somewhere up in here so it has this eccentric inside there but I went ahead and drilled it out as far as I could with the largest bit that I have which is a one inch fit up to inch and a half and that will allow me to fit this guy ah oh yeah I don't have to support it in this because every time I I get dialed in this throwing off their just sold the original to the delayed understand the hard time with it so I'm in my lowest that year with my clothes see fate that I can get and we're going to take this really really slow just try to clean up this outside diameter I don't want to take this out of the plate at the moment because I was music concentricity with the interior diameter these two opposing Joel's my indicator is set it hit 0 these two Joel's have been set so that I move 50 thousands in one direction here I'm at 50 thousands on this Joel 50 thousands of this direction that direction and when I swing it around this way we're pushed back in this direction with my parting tool on both sides gives me a little bit of room to work in there with a tool I'm exceptionally close to the jaws of the Chuck so I'm going to work that's really slow see what we got got a little bit of cleanup to do but that's the very first time I've ever turned a cam basically that is so cool and easy actually really easy I'm going to be opening up this hole here and this hole here which will allow me to fit this down inside there and what that will do is it will allow me to have the bolt press against here which presses this down and holds it tight well we've got a couple things we have to do here one of which is a reduction in terms of the overall height of the current block because we need to obtain an internal board depth of 1.48 and currently we're at about 1.6 3 or somewhere in there I have to double-check the measurement again so we're apt to face off the top here to reduce that [Music] all right now we're going to take this up to inch and 3/4 let me stop here and explain something that I had to change on the original it had that edge that lip right there and I too had that lip but unfortunately I was getting interference contact with this piece this would not drop all the way in what it was doing is was making contact with that lip so it was it was never quite receding back in there we just kind of hang up and sit at an angle which is obtained so I opted to go ahead and take it off and just remove that I didn't remove the actual height I just turned that down so that it's in line with the this offset cam making enough contact that I also had to reduce a little bit of this width as well now I've got that clearance and this will recess back in as I turn the cam I need to shorten this piece by the amount in which I board this the difference from the original diameter this piece is the original diameter the difference between that and the sides that I opened this up to so in that case I measured this out this is an inch and 328 thousandths this is inch and 3/4 1.75 the difference is 420 mm that's total so half that so 211,000 so 211,000 needs to come off this end the great thing is is it is that it is already the tap is the threads are all the way through so I won't have to cut new threads I should just be able to turn that down to the right length and we can reuse this piece to rock and roll with it and hopefully it works so I got to do that on both of them at this one and the one for this side as well well a simple test here has proven that it should work so it's with the t-slot bolt two washers so all I did was move this face up against the nose and I moved the up against the nose and then I just moved this back and forth to get this is by sight I mean we're talking about a handle here it works so let's just leave it at that I had to file it down a little bit to get the clearance and I'm not proud of the way it just kind of sticks in there it works at this point and I'm going to keep going I'm just just going to keep going keep pushing here learn as I go [Music] the size opened up got our clearance here because the boss kind of rolls up there with that radius this piece which has been turned down to the proper length the spring had to be shortened so that it provides enough clearance here's our barrel or lock barrel it drops down on top snug fit looking good our cam I had to shorten this block so that I had I only had a particular amount of height and that's this boss that stuff sticks up here and I had to make just enough room for this nut so you can see it came up just about dead-on perfect for what we need now a big question that may come up for people that are watching this tool height is also something that I have to consider actually had to take off some of the material across the bottom here my mill is not up and running completely so I had to put this in the lathe and you can see actually where I'd centered it and basically reduced this material let me show you one that has not been addressed yet hopefully you can see in this case I have to take down that much material in order for most of my tool bits to come up to Center actually undercut this some so that I had some room to move up and down move it into the correct spot and that's aligned with Center had this quick change tool post for over a year now I bought it at a yard sale hadn't build up the confidence yet to tackle it without feeling like I was going to screw it up I did make some mistakes in this but overall I'm very happy with it let me know what you think my last video that I put out the number of likes that I received on the last video and the number of comments but man that was a huge morale boost I really want to take a moment to just say thank you thank you again because it motivates me to continue to do better next video you'll definitely see this thing in action
