Machining a 5C Collet Adapter - Morse Taper 4-1/2 to 5C adapter

For today's project, we'll make a 5C collet adapter for the spindle nose of the new lathe!
The outside diameter of the adapter will be machined to a morse taper 4-1/2 to fit the inside taper of the spindle nose, and the inner bore will be machined to accept a 5C collet.
The material we'll be using is a piece of 4140 pre-hard steel round stock.
To begin, we will chuck up the material in the lathe using the 3 jaw chuck.
Then we'll face, center drill, and begin rough turning the outside diameter and major features.
Once we have our rough major outside diameter, we will set up the compound to cut the appropriate angle to produce the morse taper.
To do this, we'll use an existing example of taper we are attempting to reproduce, suspended between centers, and we'll reference against this taper to set our compound using a dial indicator.
Once we have produced our outer taper, we'll then separate the part from the remaining stock so that we can insert the part directly into the spindle and machine all of the remaining features in situ.
Machining in situ will help to create a high degree of precision for the remaining features.
Next we'll face, drill, and then bore out the material to accept a 5C collet.
And finally cut the 10 degree included angle to match the 5C collet taper.

I just purchased a JFK collet closer system that’s a bit too big for my machine, I’ll use all the parts and make it custom made for my machine. But on that spindle adapter I was thinking maybe start off with a center-less ground OD and only turn the the threaded section at the end. And do the boring. ? Not too sure yet really. But you definitely inspired me to do something ☝️.. just not sure what yet. 😝realistically a thou is not a deal breaker.. it’s not bad at all. The collets have that often, but you can true them up.

    Well done. That will be a really accurate adapter because you machined it "in situ". When you are actually using it, It will be the most concentric if you set it in the lathe spindle at the original position that you made it in. You can probably find this ideal position with a test indicator against the inside of the adapter, and then clocking it around until you get the smallest TIR.

    Thanks much! Yeah maybe when the draw bar is done we can check out the runout as well and mark it in the best position. The spindle has a "1" stamped near one of cams so that would make a good reference to mark against. Thanks!

    exactly. We wouldn't know enough until the adapter is actually constrained by the drawbar. 5c collets bear mainly on the front of the object they are holding, so that's where I would measure. You might throw a collet in and tighten the drawbar to get the adapter seated, then remove the collet and test. It might even be more practical and real-world to do it with a gage pin in a collet, although then we're also factoring in the concentricity and roundness of that collet as well. @@hersch_tool

Honestly, if we see reliable and repeatable .002" or under on the pin, then I'll be happy with that, at least for this first attempt.

    That is a good little project. While this will be better than no collets, (collets are great) the fit should be really tight (-0 +0.0002in from the body diameter). You could add a hardened ring and lap it to size. (I would use a new Hardinge or Schaublin collet to test unless you have a good 3 point internal mic). Threading the big end for an ejection ring will be really helpful if your taper is a good fit as Morse tapers are self locking and will get really stuck :)

    When using a boring bar, only use as much stick out as you need to make the cut, and no more. If you only need to go 1.000" inch deep, then set the bar with about 1.250" stick out...just enough to make your cut, and have enough clearance to work. That will make the bar much more rigid and reduce chatter, and give you a better finish. Also, if you are getting runout with 5C collets...5C is for nominal sizes only, not just any oddball size that will fit in the collet. For example, a .500" 5C collet will hold a half inch tool or piece of bar stock, but not a .496" piece of stock. It has to be exactly 1/2" or very, very, close to it, or you will get runout. They are not like the ER series of collets, which have a wide gripping range. If you want a wide gripping range to be able to hold odd sizes of stock, 5C is not the best choice. I would use ER collets for that. I would go with ER32 or ER40.

    @@hersch_tool honestly, I had no idea what I was doing, back then. I have had zero formal training in metalwork, so everything for me has been reading and then trying things. The 5C adapter I made, I at least got the order of operations correct, and the thing physically fits well, but I made it out of some weird stainless because that was the piece of stock I had which was big enough. But this means it's unlikely to be hard enough to hold up under real use. I should commit to re-making the thing and actually building a draw tube for it. So, not-so-great, my mind. I was flying by the seat of my pants. One thing I did was use a punch to make a witness mark on the adapter so I can always clock it to the same position in the spindle bore. I got my lathe used, so this might make a difference or it might not. Either way, I'll do it again when I re-make the thing.

    I would say overall you did an excellent job at the setup and the video. The surface finishes are pretty bad though. Sometimes it can be caused by the spindle bearing play or the longitudinal feed and the ways. But you even got the poor finish using the compound crank. so I would go with a combination of tool dullness and tool feed too fast. I have found that some coated carbide tools are not very sharp and I've had success with using a diamond hone to get a razor sharp edge to cut finish passes on certain materials. good luck.

    I always like a guy who tries. If you find you get runout it could because the parallel section in your adaptor is just a tad too large. A 5C relies on support at the back , the taper is for closing as well as for support but it does need a close fit, almost an interference fit, deep inside to maintain concentricity. Are those a set of mitutoyo calipers you have, I can't help notice the zero is in an odd position, if they are you might like to look at a video I did many yesrs ago on setting zero easily using the "special " tòol , a bent bit of wire.
