How to DRILL & TAP Hard Jaws | Big Lathe Chuck

You say: Thanks for watching! I say: Thanks for filming, editing and uploading! And thanks for sharing tips and tricks! Greetings from Germany

[@hot_wheelz]

Well look here folks, this here is a prime example of the fabled 2nd video in 1 week. Thanks Karen and Kurtis!

[@maxcactus7]

Monday CEE - It's like having TWO Fridays in one week! Great work, Kurtis.

[@valuedhumanoid6574]

I had one of those highly repetitive jobs where I had to run 50 pieces in a row. I was using loose shims to prevent the jaws from marking up the workpiece. After 30 some parts I forgot to put one of the shims in and of course it scrapped the piece. After that I made my own set of these. Learn as you go!

I have a Bison 3 jaw in my little Atlas lathe, really nice chuck but didn’t come with outside jaws (it was on the machine when I bought it). I emailed Bison and they provided me material to figure out which jaws I’d need since my chuck is old and not listed in even their internal documentation. They asked an old timer and he knew which ones they were. Really great company.

[@arkeyethenoo]

[@krisholt]

A quick tip when installing jaws on a scroll chuck, turn the scroll just past the slot for the jaw, put the jaw in the slot and back the scroll up until the jaw falls down. This trick ensures the jaws are in place, and not hanging on a burr or similar.

[@CuttingEdgeEngineering]

good tip thanks for sharing!

[@steveanderson4768]

It is amazing how the material when you drill it go from the hardened areas to the softened steel of the jar truly does make a huge difference like everything he does when you use your head and you think about it rationally it’s actually quite easy thanks Kurtis

[@Ghine91]

The gags you both made at the end of the video are pretty! You looks like to got a real and honest relation, the way Karen help Kurtis to find the right way to explain is literally a love demonstration!

[@paulg3336]

An alternative holding arrangement for soft jaws is to design them as a U shape and on one of the legs bore a hole and epoxy a thin neodymium magnet to hold it on the chuck jaw. If the magnet is close to the thickness of the brass , chips that stick to the magnet can easily be wiped off.

[@jasonxd5738]

Always amazed me to see how many different types of tools you have. Seems like every video you pull out some new manner of tool from who knows where! Myself and I'm sure many others are a little jealous at the amazing workshop you've built up over the years!!

Gotta love it when one of your favourite chaanels drops a bonus video, top job and it'll definitely make your life easier than using loose shims all the time.

[@CuttingEdgeEngineering]

Agreed!

[@armageddontools]

@@CuttingEdgeEngineering Speaking of wrenches you should make a short wrench/adapter for your cordless drill-one side with square profile and on other side 6 points. That way you can wind up or switch those jaws faster ! You still tighten them with good old key but cordless drill is just pure awesomeness when it comes to winding jaws ! Think about it . . .

That's a great idea. And if you cannot use the bolts for some reason [maybe you're butting the work up against the jaws], then the old method can still be used, because there are just screw holes, no protrusions.

[@rockwell6594]

I can only admire Kurtis's courage/confidence in starting an M5 tap into what is still probably fairly tough steel using the rotational inertia of the milling machine spindle. I sometimes do that with unimportant work pieces but would balk at doing that with the chuck jaws. I enjoy your work. Karen's videos are excellent and Homeless and the wildlife are a heartwarming touch . Cheers.

[@melgross]

It would scare the bell out of me to do that. I was picturing the tap snapping off from the sudden shock.

[@rockwell6594]

@@melgross It's helps that it is a spiral fluted tap, which clears its own continuous chips if everything is going right. The other saving is that if you tighten the chuck just the right amount, the tap will slip in the chuck rather than break, provided that the tapping gods are on your side that day. I guess it comes down to being confident about the jaw material based on the way it drilled and being confident that the tap would then do what it is supposed to do, but it still made me winch when I watched it. Cheers

[@melgross]

@@rockwell6594 it certainly didn’t look like it slipped. And that’s always a ticklish adjustment. He would pretty much have to use a spiral tap to get to the bottom unless he was willing to drill deeper and crunch the shards at the bottom with a spiral tooth tap.

[@alro2434]

Never had a spiral tap, loved its chip!

[@AlanSprague]

Sweet bonus video! and right at my lunch break as well good times! so I am really curious to know if you can tell the difference in the milling machine now that you have done that massive maintenance job from a few videos back? It seems with so many of the bearings pretty much shot seems like it would be much nicer now.

[@ronblack7870]

the bearings were not shot. the noise comes from the straight cut gears in the head when he shifts to low it goes through the gears. high just goes straight through so quieter. in the video at the end he found the noise was the same before and after.

[@broheim23]

Another great video! I greatly appreciate that you both took the time to record and edit a video of a relatively simple job. Thank you both for the extra work. One quick question: do the brass shims you're semi-permanently mounting to the hard jaws affect the part running concentrically? To my mind it seems like it might induce an unintentional offset.

[@djpaulk]

All 3 shims are 2mm thick, so they have no affect to concentricity of the part.

I'm sure you've covered this before, and anyone that has changed jaws on a scroll chuck should know this, but you didn't mention that they are marked and have to be put back in the right place. Might save a "first timer" some frustration. 😁 And you can definitely see where the end mill gets through the hard layer! From essentially powder to stringy swarf. 😁

[@CuttingEdgeEngineering]

hey mate thanks for mentioning that here, I did mumble it to Karen but wasn't worthy enough for the video 😅

[@JonoMacIntyre]

Thanks for this comment, I was wondering if there was something like this to avoid a painful process to get the jaws all aligned

[@uncleheavy6819]

That surprise video on a Monday totally screwed up my internal calendar. 😆 Great stuff, as always, guys.

[@TrevorDennis100]

Well that's interesting. It never occurred to me that chuck jaws were not hard all the way through, but it makes sense thinking about it. I am surprised that you were able to drill into the jaws with an end mill, but I went back and had a closer look @4:06 and could see that your end mill had cutting face and clearance all the way to the centre. I'll check later, but I think my carbide end mills have a recess at the centre and definitely won't drill straight in. I do have 6mm carbide slot drills though. I was also worried that you used a tapping size end mill as the tap would still have to cut through the hard outer 2mm, but that was a fancy looking tap. Was it also carbide? I'd be worried about breaking a carbide tap if they exist. I am going to look at doing the same mod to our lathe, but using the 6mm slot drill so the tap only has to cut the softer inner material. So thanks for another super useful tip. I am 73 and long since retired, but I still love learning new things.

[@HappilyHomicidalHooligan]

The end mill was larger than the screw hole (5mm end mill, then a 4.5mm drill & tap) so neither the drill or tap had to cut into the hardened top layer... After he finished cutting the very first hole, Karen took a close up of the hole and you can see the shoulder where the end mill stopped cutting and the smaller threaded hole starts...

[@LanceMcGrew]

The end mill size cleared the outer tap diameter. Also he is using what is known as center cutting end mill.

[@MachiningandMicrowaves]

The slot drill was 5mm, the drill was 4.2, the tap was M5, so it wouldn't need to cut the hardened layer because the slot drill had removed it. You should be fine with a centre-cutting 5mm carbide cutter.

[@dalejones3862]

Two videos u are spoiling us keep up the great work

[@CuttingEdgeEngineering]

Thanks! Will do!

[@Hagop64]

Monday vid!?! Also, is there a reason you don't have your overhead crane reach over to your welding area? I notice you frequently moving pieces between the lathe-fork lift-welding and back. Seems like that would save time if the crane reached over there.

[@SeanBZA]

Probably crane is at end of limits, likely original use of the shop had the crane only in use in part, and a dividing wall to the other side. Now the shop is larger the crane is still limited, so the forklift and mobile crane get a lot of use in place of it.

I saw you cranking for a while to get the jaw out of the chuck, what about making a little adapter you could fit on an impact gun to move the jaws in and out quickly especially when changing from interior to exterior. There may be a good reason I have never seen one.
