Hey everyone! Lots of concern this week about my tapping setup. Yes, those Starrett tap handles do have a tendency to hold the tap a little crooked sometimes. However I’ve been tapping holes with that setup for ten years and it doesn’t cause any measurable error in the hole or threads. I’ve tapped tens of thousands of holes that way and never seen an issue. It definitely doesn’t cause a hole to move 0.75mm in a part. 😄 That error most likely came from the centre finder. That was the error prone step in the process.

[@markmonier-williams2508]

Ahh yes, everyone is an expert this week because Joe Pie just posted a video on the vagaries of using tap handles with a spring loaded centre.....

Gwen, center finding with that “center finder head”, I have found that that layout method rarely goes thru dead center. I always put on one line, and then put a second line immediately at 180 degrees. If they aren’t one on top of the other, your center is in the middle. A second pair of line at 90 degrees will usually leave a tiny square or rectangle. You know where to go from here. Thanks for all your effort. Paul

[@petem6291]

Quinn , you always do nice work ...This project reminds me of a similar type of tool we had in the shop years ago, that the torch would be on the business end of the tool and a tracer pointer would be on the other end, and a little motor would trace the outside and the torch would cut the shape I thought it was the coolest tool. now we have a water jet machine and the pantograph torch just stands guard duty in a corner of the shop....

[@Hawk013]

So a cautionary tale about the afore mentioned stacking tolerances and rounding errors. I had a turned part to make that had about 20 or so features, all measured from one to the next. Now the engineers, working to "military specifications", decided it would be best to round all measurements to the appropriate significant digit for the accuracy required. What that means, of course, is all the 3/8" measurements were rounded from .375 to .38, and so on. Not being willing to put up with such stupidity, I had the engineer run off a manufacturing drawing for me with all the featured measured from one end. Needless to say, the QC guys spent quite a long time trying to figure out why my part was a different length that what they calculated off the print, but was still correct. Good times...

[@brucematthews6417]

You mentioned using light pressure on the hoop but during the fitting steps of the hoop onto the first center piece it looked like the hoop was pivoting a little on the "sides" that would have closed inward when the jaw pressure was released. So I'm thinking that even with the light pressure there was a slight oval result. It makes me want to move ahead with my small fixture plate all the more.

[@Ben.last.name.]

Great eye, Bruce! I was thinking fixture plate was the only option, too, as any clamping pressure would invariably oval the hoop.

[@thedabblingwarlock]

I have loved watching you make that mechanism. I have my grandfather's old drafting table and if the mounting kit I found to replace the mounting hardware for the Mayline parallel bar doesn't work, my plan B was to see about making or buying a drafting arm like the one Inheritance Machining uses.

[@matiastripaldi406]

Basic non-machinist question: why did you go to the trouble of drawing a center in the round plate, then drilling it out on the mill, then use the threaded mandrel on the lathe? Couldn't you have chucked the outside of the plate, drilled through the center (on the lathe), and then used the mandrel?

[@kwaaaa]

My guess is that they are using a 4 jaw chuck, so it's not self-centering. If you have a lathe, it's always a chore to swap chucks and you try to make due with round-about ways of doing things to avoid the extra effort.

[@matiastripaldi406]

@@kwaaaa yeah that's true, my method would have needed a 3jaw since there was no way to indicate in the outside of the plate while still gripping it.

[@evanbarnes9984]

I'm not totally sure about this myself, but I do a lot of laser cutting for work. Laser cut edges are not perfectly perpendicular to the faces of the material being cut. Depending on the focus height of the laser, you get a sort of hour glass shape on the edge. This might make it so that it's hard to actually get a good grip on the outer diameter with chuck jaws. Or it might make it settle into a crooked position in the chuck. Laser cutting also hardens the outer shell of the metal, and metal that is hardened is also more difficult to grip. The jaws in a chuck actually slightly dig into softer metal to create grip, but don't do that with hardened steel. That's why you don't put end mills in a drill chuck, and instead use an end mill holder. Personally though, I'd probably have tried just putting the plate in the three jaw chuck on the lathe and drilling it out like you said. Avoids having to indicate anything. Quinn knows so much more about machining than me though. But I do know in previous videos she's done a more complex process for a part and then realized after the fact that there was a simpler way. It happens. Also maybe she just wanted to show this particular technique. This is an educational channel, and a damn good one!

[@joshuawills5242]

A bit more after Evan's good points about metal hardness and references for clamping: It might have just been faster for Quinn to do this in the mill. She would have had to swap out the 4-jaw chuck for a 3-jaw, then probably flip the jaws to hold the large diameter part. And it's entirely possible the lathe was setup for something specific, possibly that she didn't want to break down - maybe she had already indicated-in the mandrel. So my guess / suggestion in general is that - "no really good reason, it was just easier in the moment".

[@mrimmortal1579]

@@evanbarnes9984 I think that your guess is the correct one. Quinn mentioned in earlier videos that the laser cut edges leave a slight taper to the edge. A tapered edge is not just difficult to grip in a chuck, but the taper leaves only a single point of contact on each jaw, which reduces the rigidity of the part as well. If the part had been laser cut much closer to the finished diameter, we would have likely seen Quinn make up a superglue arbor that roughly matched the diameter of the part, and then dial in the whole thing on the four jaw chuck to the closest approximation of centered to the outside edge, and then turn down the final diameter and drill/tap the center hole in one setup. But since she had plenty of room to finish the outside diameter, a close approximation of the center hole was close enough, and saved her from a good deal of fiddly metrology.

Why don't you use the dimple to drill the holes on the drill press with a floating vice? Whouldn't that be much easier than finding the dimple position with the pointy thing and still give you enough precision?

[@PioneerRifleCompany]

I was waiting for your video! Good work. Have you thought about machining the sliding surfaces on the static portion of the tool jig? If you polished the under/outer surfaces and put an oil groove on the plates clamping it you might get a better action, or feel, when you are grinding the tools. Just a thought. :) Keep up the good work!

[@Maltanx]

Hi Quinn. Just what is possibly a very dumb question... For this project you keep saying that you don't have the metric tools to measure it properly, but why would that matter? 1 Inch is just 2.54 cm exactly, going from imperial to metric means just to divide or multiply the measurement by a fixed number. Does it really matter that your micrometer measures in thousands while you need micrometers? 1thou = 25.4um, exactly by the same definition of the inch. There is no rounding error, as every single imperial unit is defined exactly by a metric unit. Of course this is a really basic observation which you already know and obviously there is a good answer to it. But I'm not a machinist, and I swear I can't figure it out why that would be a problem.

[@kindabluejazz]

I was thinking the same. There's no reason you can't use an imperial micrometer to measure equivalent metric values.

[@SouseMouse]

I too have only imperial micrometers, and I do exactly what you suggest. I've memorized a few of the common sizes I encounter. The other thing I often do is switch the DRO between units depending on the job.

[@johnmerrill6999]

For what it's worth, an inch is *exactly* 2.54 centimeters, by definition. The definition was changed in the 1950's. (When in the 1950's? Depends on where you live.)

[@mrimmortal1579]

It’s helpful to know that a standard 1950s is equal to 1.0001384 metric 1950s.

[@wagnerfarm5550]

At 17:40 you said you didn’t have a measuring tool to measure that step. Try a straight edge across the face and gauge blocks or feeler gauges. See what fits till it lifts the straight edge from the face and allows light between them.

She was measuring the diameter, not the depth.
