Toolpost Dial Indicator Part 4: Final Machining and Assembly
HTML-код
- Опубликовано: 1 окт 2024
- Today we finish the machining and assemble the toolpost dial indicator holder. Last week, we machined the part down to a waterline with Talon Grips. This time we flip the part over, remove the top hat and finish machining the features on the back. Then we go over to the lathe and make a knurled height adjuster.
any chance the files for this design are available? i'd love to try machining one, or maybe just get lazy and 3d print it
I would also like to make or purchase something like this.
It would seem the next logical step for such a nice project result would be anodizing - any chance you're going to get into that?
Yes I would like to see that as well. a nice Cherry Red?
One trick for finding an edge thats underneath a lip like that is to use a gauge block or other known width greater than the lip and hold it against the machined edge of the part, then touch of that and offset by the known amount. Would have saved having to do two setups.
Hi, first let me say, I do like your videos and your work. I have an honest question, not met to troll or anything, I am curious why two gauges? would you not be able to do with one gauge and just have the tool post grooves on both sides? with the pin facing forward and groove on left and on right, you could achieve the same, just a longer pin for more spindle clearance. your part looks nice, just looks too delicate with pins protruding each side. - please dont take this any other way than just honest curiosity. (sometimes its hard to post questions because people jump on you when you do)
James you should hard anodize the aluminum, it will eliminate the wear and sticking it is really interesting i have been thinking about doing a video of process. I use a small chest freezer.
I’ve 3D printed something similar for myself and a few friends. Mine only hold 1 dial.
Nice tool James, If I used a QCTP I would make one. A suggestion for altering screws, or threaded rod. I make long nuts using brass hex stocks and split them to avoid damaging the threads in the chuck. I have made them as needed, now I have a collection. Excellent video, as usual.
Thank you. Yes, I've seen the split threaded bushing technique. I do modify a fair number of screws. I should probably make some.
Just found this video series and I believe that yo are using an AXA tool post if so I would love to purchase one of these as I doo not have a milling machine yet. Would you consider making one for me?
I really love your content, I have learned so much it is a real treat to stretch the limits of what I can do. Thank you for all you do James. Thanks Kenney
Damn nice tool holder James. Are you going to Anodize it?
Very nice project. And very nice set of videos, so nicely edited. Congrats
In rank Aussie - Bloody beauty mate.
If you run out of projects you might try to anodized it. Just for fun.
Absolutely superb!!!!!
James, you are my kind of builder. Wow! I probably have enjoyed these 4 videos more than any other series of videos I have watched.
May Jesus continue to bless you with gifts; that most simply do not have. Sadly, I am one of them; but now I have some one that CAN and WILL do it. So why ask for more! Huh?
A tip of the ole' hat to you kind Sir!
Thank you.
Are you selling these? Or is someone else making one similar?
Did you make the spider yourself?
You should get the aluminum hard anodized
Great job. I only came across your videos a few months back, and I’ve been working my way through them all. Great job on this, I really ought to draw one up myself and mill one out for my lathe.
I’m loving your in depth Fusion 360 work, that’s really helping me understand the more obscure features of the CAD. Keep up the great work.
Have you considered selling these? If so, what would be the price?
Too much!
Really interested how you calculate your chamfer toolpath....do you just do an offset? But then how do you figure depth????
Thx
My first visit to your channel. Amazing work! Wondering however why you chose to put “garbage” indicators into such a meticulously crafted fixture. Sort of like ordering a Mercedes, but with cloth seats...... I’m not suggesting that you need Etalon or the like, but at least Mitutoyo or Starrett (perhaps even second hand). Nice work though, just disappointing as a viewer to see you diminish yourself, but that in reality is just my opinion. Otherwise, you do beautiful work and I look forward to watching some more of your content.
James , how do you your chamfer tool to come in at midheight on the work?? whenever i zero my chamfer tool , fusion seems to send it as low as possible on the 45 degree of the tool , almost to shaft.. So i now zero the chamfer tool a bit higher , about 2 mm off the model top and that seems to create the desired effect
A tip for holding threaded parts without damaging them is to wrap cardboard around them, Strip from cereal box the width of chuck jaw works well, you hold the ends between two jaws. Because the fiber is soft it will form into thread, increase gripping surface and prevent damage (unless you go crazy tight)
Very great job. When you were fly cutting the bottom to size. You said it would be hard to get zeros. You could have used a threw hole to indicate. Offset from there or move the X and Y. Set them to zero. Great job keep up the great work.
It would have to be bored. A drilled hole is not accurate enough.
@@Clough42 A drill was ok. You had to a couple of offsets. To blend it in. Or If there was a Zero stop at the X .Then at the solid jaw. A zero Y Then top a jaw for Z. Would that help in in programming . Just a thought. Great work keep it up. Never stop.
Your attention to details is impressive!
Thank you.
Thanks for sharing ... I will be making one in the not so distant future ... 👍
How much to purchase one of these from you. Thank you
I'm not really set up to manufacture them efficiently.
Came out great, nice tool.
Thanks!
That would not fit my lathe, it would not be any use to me whatsoever, yet I still want it. It's that nice...
Great video series, as usual. How can I get the f3d?
You should anodize it - lime green to the parts you printed for you mill
Very nice. 👍
Great build, next project though a clamp or even cut knurling tool, I think HSM did one not all that long ago!
Great part!
Anodize?
A very neatly done piece, much better than using mag bases on the clocks.
Yup, hard anodize or electroless nickle.
Love your channel! - I would put a sheet of tar backed aluminum roof flashing across the back of the lathe. Would keep the resonance/noice down. I'm picky though. :)
Oh, interesting idea.
James, just found your channel the other day, very nice job with the shop AND the video production! What are the indicators you use in the holder? I hadn't seen these smaller, shorter throw indicators until now.
These are the indicators I used: amzn.to/2BFIDO1
This indicator holder unit is looking nice good approach in my eye of the second side operation. As a manual lathe operator it is a great work tool you have made. Nice tool call the aluminum one a prototype and then make it in steel if you like. Edge Technology (we do not use) they use aluminum anodized red so you are fine with aluminum to us. Great job and thank you for sharing the series.
Thank you. I think anodizing the aluminum would make a big difference. The aluminum builds up a hard oxide layer on it anyway, but I think the anodizing process makes it a lot tougher. A quick web search suggests that hard anodizing cuts the coefficient of friction against steel by almost 2/3. I've thought seriously about getting set up to anodize, but I really just don't want to deal with storing and disposing of the acids.
I have the same spill proof cups. They work great but I found an even better spill proof cup on amazon. They are called Melissa and Doug spill proof paint cups. They hold more oil, its easier to put the brush in the hole and its especially easier to control how much oil is on the brush because you have more area to wipe the oil off the brush. Just a thought if your interested. Oh and a nice magnet in the bottom works well too
Good tip. Thanks.
You'd like me to tell you what I think ? Well, I think you're a sick machinist and a darn good teacher ! Thanks for the content, you got a new subscriber. Keep it up !
Thanks!
Very cool tool! Maybe a cover for the back side of the plunger to keep chips out of there?
Very nice series! Keep it up!
Thanks!
OK I'm intrigued what is the toolbeah? Sounds Finnish. A New project? ;-)
And...there go my three Finnish viewers. :)
That lathe chuck spider is a great idea!
That thing looks nice and is also usable.
That being said, I noticed one feature that might give You some trouble in the future. There is this open space between the dial indicators. That should be covered somehow in order to prevent chips/dust/dirt landing in there.
Or mill a hole in the middle where the chips can evacuate.
This should never be mounted while chips are being generated, though.
any chance of sharing the fusion files? great videos keep up the good work
Yes. I will get them organized and uploaded shortly.
@@Clough42 awesome thanks for sharing with us garage builder's
@@Clough42 I'd be interested in the files as well, is there somewhere they can be downloaded? Thanks!
@@Clough42 did you ever upload them?
Great work!!
I think you show anodize it! A bit of colour, surface hardness and perhaps less sticky on the tool post.
I thin that would help. I looked into setting up an anodizing line about a year ago. At the time I was thinking about wear surfaces on aluminum pulleys. It's totally achievable in a home shop, but it requires some care in storing and handling the acids. After doing the research, I decided I didn't really want to deal with it. What I need is a friend with an anodizing line who wants to trade for some CNC work. :)
Thanks, really enjoy your video, great teacher. Can you do a 4th axis project. Convert Manual Rotary table to Automatic or Semi- Automatic to be used on Mill
I've thought about making one. I did build a small indexer for milling hobbed bolts for 3D printers, but I would love to have a larger indexer with a chuck or maybe even a general purpose fixture plate.
It may be my eyes, but it looks like the chamfer is wider on the acute inside corner of the dovetail. Is it really the same as the rest?
As usual, your video production and content is gold standard professional. I'm mystified why you don't have even more subscribers.
You're right. The chamfer is much wider around the inside radius. I'm not sure why that is. It doesn't show up that way in the CAM simulation, so it must be something about the tool I'm using. Just visualizing it in my head, it isn't obvious to me why that might be, but it clearly is.
@@Clough42 - If the tip angle of the tool model is smaller (more acute) than the actual tip angle of the tool, the toolpath would go significantly further into concave features, yes? I'll apologize in advance in case this is something you've already checked & ruled out or my visualization faulty, but what is the tip angle / diameter of the tool model you are using for the spotting/chamfer tool itself?
After some thought, it seems very like a problem I had trying to stupidly program a chamfer on an inside square corner. I had accidentally picked a 100 degree chamfer tool model, and the program kept leaving more untouched profile in the corner than I simulated.
I also had some classmates who failed to account for the flat on the tool tip when touching off Z height. Their chamfer widths were way off, and wonky things happened on any kind of concave feature. Some of the models we had to work with assumed a sharp pointed tool, some assumed the standard flat/end diameter.
Just some seemingly related experiences I've had, maybe they are relevant enough to cause a light bulb to go on for anyone pondering 'impossible' errors with chamfer or bevel programs.
Beautiful job! Beautiful design!
Omgs that intro is perfect! 😂❤
Veeeeery nicely done.👍
Just became a subscriber, great content! Thanks!
