Two morse tapers on the same spindle to connect a chuck to a milling machine or lathe. The challenge is to manage to center.

Thank you ! I've been ready for the beach for almost a month. But don't tell anyone that, please. My wife doesn't need to know.

I have a slightly different opinion about that for an home machinist, these arbors need to be very straight so better to buy them already done, after all , it is the base for all works to come and for standard cones as MT2,3,4 , R8 and JT6 and33, they are very cheap so if your machine have standard cone attachement, you,re better to buy them However, I can say that you done a very good job on that

Surely there is this option to buy these tools but what I can't buy is the satisfaction of achieving something alone and especially of conversing with you and those like you about our own ideas. Money can't buy that. It's worth too much . Thank you very much for your comment !

Morse tapers are easy to make with electronic leadscrew and cross slide :)

Looks great, I have the use angle blocks or something similar to get my angles right, I see you just going off the gage on the lathe, glad it worked out. Thanks

@JIMMY916 11 күн бұрын

I know ”exactly” where the position for the required angle is from the old projects where I used measuring devices. The perfect realization of the angle 1 29' 30'' is anyway impossible to measure for me, but I'm close. Thank you very much for your comment and appreciation !

I see your loyal companion is still sleeping on the concrete floor. Could management consider up grading his position and provide a soft bedding for his poor old bones.

To my shame I didn't think of that. Thank you both for the idea !

I would have left a few thousand on the spindle and then heat treated and ground it to size. I feel this would provide a good result.

Yes, it's a good idea, but I was afraid that it might deform from the temperature. Anyway, it's a hard steel and I don't think it will ever deform under the demands of my small lathe. Do you think I can do it now and finish with scotch brite without risking it getting deformed ? Thank you sir !

well, in my expirnece even with a 3-jawed chuck, i have to center the rouynd stock in it before i start, i noticed when you started it was already wabbling. maybe if you centerted the part before starting that may have helped? just a possible idea.

@JIMMY916 11 күн бұрын

Yes, I definitely should have done that in the beginning. It's a rule I always forget, especially as I needed to do this now. This may be a big mistake. Thank you very much for your comment !

You could have put a dead center in the 3 jaw chuck and keep concentricity by turning between centers, no?

@JIMMY916 11 күн бұрын

My tailstock can't use a normal live center because my lathe has a milling table, thats why I have to use ”my long live center” ( if you want see my an old episode when I built it ) which beacause of its lenght is not very rigid to use your method. Otherwise, your method is good and is used often, but unfortunately I cannot use it. Thank you very much for your comment !

@@JIMMY916 The tolerance you achieved was quite good working with your long live center. In my experience, most precision tooling is ground to specifications (minimizing tool pressure). Even when machining in an ideal setup, it takes careful attention to detail to get as good as you did; IMHO you should be proud of your accomplishment.

Yes, i'm proud that someone appreciates what I do. Yes, I'm proud when someone sends me their idea and opinion in comments or likes. With you I become proud. And I hope to become a good machinist to reward your time. Thank you sir !

I have only turned a couple of MT3 tapers so I'm no expert but I believe you should finish them with emery and blue the taper to check its fit as its very difficult to feel any misalignment but it can cause the chuck to slip in use, especially large holding chucks like that. Very nice job but I would recommend you take the time to check it

@JIMMY916 11 күн бұрын

Unfortunately for me, the cone tapers of the milling machine and tailstock are no longer as they were on the first day so that I can use them as a reference. Someday I will buy an MT3 reamer and I will rectify them and then I will use your method. I may be not be happy with the result :) but it really is the best way to check. Thank you for your comment and for the suggestion !

@@campbellmorrison8540 Is it true that they are very expensive? What I found is almost 200 us dollars (MT3) without shipping costs, which makes me put off buying them.
