Mill Stop Fixture Final Assembly

[@wheelieking71]

I really admire your love of a good challenge! The lengths you take to avoid any manual tool changes are pretty amazing. I would give just about anything to "apprentice" under you. And, I am a 46yr/old shop owner myself, if that says anything about my respect for your knowledge. Your videos are awesome Peter.

[@willywgb]

I feel the same way. Peter is one of the best (if not the best) CNC Machinist on KZbin. I really like that most of his videos are 5 axis work. There is not many 5 Axis Guys on KZbin. He also is very good at explaining so you understand and shoots great Videos. Cheers Willy

Awesome! Awesome! Awesome!, Man I can never get enough of these, I have binged all your videos for Days, Your knowledge, skill and ability and willingness to teach us has no equal. Sincerely With Appreciation Laurence

[@DesignDynamicTactical]

You're not only an engineer but an artist! Beautiful tombstone and tailstock work!

[@copasetic216]

This is incredibly well thought out and also made. I doubt that money could buy the same level of quality

[@davestrong6472]

I watched you 3 part video on squaring up parts this morning, what a great series...I had no idea how much movement their was in vices. Thanks again for the videos. Dave

[@EdgePrecision]

As I said in the video this isn't something I would do unless the job required it. It is a very detailed and time consuming process but it does work with less than perfect tooling. I was just trying to present a different way of looking at holding parts in vises. Thanks for the comment.

[@tyouboxjr]

Wonderful work , the most wonderful is to disseminate this valuable information to benefit people with this specialty, my appreciation and love for you.

[@lorenlieder9789]

Very nice fixture Peter can not wait to see the rest of the machining .

[@EdgePrecision]

Thanks. Its coming I cant wait either it been a long time since I started this project.

[@billdlv]

Looks good Peter, that shrink fit worked perfect.

[@EdgePrecision]

I have done this many times in the past but it always makes me nervous every time for some reason. One time I was shrinking a Inconel liner into a hydraulic accumulator and it stopped half way in (It was about 18" long). Nothing would make it move, even a 60 ton press. I had to machine it out and start over. Thanks Bill for the comment.

[@egdjr1]

So cool Peter, nice fit up and design.

[@jimmilne19]

Looking much forward to the next stage. Very nice work. And, thanks for sharing.

Jim, Thanks for the comment.

[@skirifles2076]

Great vid again Peter....love your attention to detail and machining practices. I can't wait to order my stop once your ready to take orders. ......SKI

[@EdgePrecision]

Thanks SKI, It shouldn't be long now. I am going to Mexico at the end of the month for two weeks to check on my construction project. After that we shall see.

[@alexanderrode6983]

Great Fixture! I hope I have the time to build something like this for my own mill...

[@EdgePrecision]

Thanks I'm sure you will.

That came out great, and alignment was fast and easy.

Thanks Randy its getting there.

[@realfixesrealproblemssewel82]

I Think that you are one very knowledgeable person. Where did you learn all your knowledge on these machines? Very impressive indeed 👏

[@EdgePrecision]

Just by doing it. And working with experienced machinists.

[@JeffreyVastine]

Nice work Peter!

[@jobkneppers]

Peter, is there a next video where you cut the final shape in the mill stop fixture and machine real parts? I'm curious about the results. Thank you for your great content, Best, Job

[@EdgePrecision]

I'm sorry. I haven't been able to get back to this project yet. A number of years ago we had a hurricane here in Houston and our house flooded. It took over a year to repair (Actually it not completely done yet!). And recently my truck accident and rebuilding the truck. When I re powered the Haas TM-1 in the garage (This machine) there was a problem with the 4TH axis. either the drive or the rotary table. I haven't had the time to trouble shoot this problem. I have actually partially machined the fixture (Hope I haven't lost the video clips on this). I have as of this time unmounted the 4TH axis and this fixture off the table and disabled it in the control. So I can still run the machine. Thanks Job Kneppers!

[@jobkneppers]

@@EdgePrecision Peter, I totally understand. You had a lot of problems to deal with and then less important stuff has to move because of that. I hope you're doing ok in this weird period where everything looks to shift in a good or a bad way. I'm viewing all your videos bottom up and I'm really impressed with your work. I'm an Industrial designer with my own shop and everything I design I also build to prove my plan to the customer. All my turning is conventional (A Hembrug DR1 and a Hembrug DR133; boths great Dutch machines) and I also own two conventional milling machines (a Deckel FP2 and and a Mikron WF1) which both are also great machines. Next to this I own a Haas MiniMill (with a fourth axis) from 2007, which is controlwise the same as both of your machines in your garage. It functions great but the lacquer job is unfortunately falling apart. I'm not experiencing any problems with getting work in this period. People are actually asking more than I can handle as a oneman shop. This is luxury and I'm grateful, but I also looking forward to my first vacation in three years... I'm enjoying your videos and I love you as a person (I'm married; no worries). I hope, some day, we get to meet and talk about the stuff we both get excited about and the stuff we both hate. Unfortunately we live ways apart so meeting is not that easy. But, if you want to visit the Netherlands, which I think you're familiar with, I have a place to sleep. Best regards, stay safe and be happy. Job

[@dlstanf2]

precision I must say. sometimes I'm amazed at the size of parts you create. how do you keep your tools sharp enough for these dimensions. CNC machines & tools wear as well as manual machines, even with error correction.

[@EdgePrecision]

It is of course always up to the machinist to keep track of his dimensional tolerances. Whether the machine is new old manual CNC it does not mater. Remember this it is the man not the equipment that does the job. Does for example having the most expensive camera make you a better photographer? Of course not. I have seen machinists hold precision tolerances with just calipers. A lot of this has to do with feel. If you don't know how to play a musical instrument can you just pick it up and play. no! With time and making mistakes comes experience with that comes skill. My Father always told me put a man with a skilled craftsman and with time you will get another skilled craftsman. This is true there are many ways to do things are they all the best? It is strange I am mostly a self taught machinist but I have known men who went thru a traditional apprentice program. When we compare our ways of doing things they are very similar. Why is that?

[@kentvandervelden]

Wonderful view and reminds me of how teaching has changed. If you've not read Shop Class as Soulcraft, you may enjoy it.

[@humanmissile]

Hey Peter is there going to be a sequel to this mill stop fixture video? I would love to see you machine it. I am wanting to make one of these for my Robodrill's 4th axis too!

[@EdgePrecision]

Yes I’m planning to continue more videos on this project. When I finally turned on the machine. The last video on making the hose real part. Honey do project. After a long period of not being run. The machine gave me a error message on the A axis. So now I have to trouble shoot that problem. Such is life in the machine shop.

[@JohnHollowell]

I believe you forgot to put the oil seal in. (the one mentioned at 9:25) I can't tell in the final assembly if it is there, but I don't see it.

[@EdgePrecision]

Sorry I forgot to take video of installing it. It is in there. I knew this question would come up after making the video. Thanks!

[@jrvm77]

excellent video!!!!! keep them coming....

[@daveanderson2316]

Peter did you ever finish this?

[@Panzax1]

Great work ! I really like this series. Regarding the sealant you are using: I used to use that kind too. After I tried Loctite 518 there is no way I am going back: Needs very little applied and seals properly every time.

[@EdgePrecision]

Thanks! I need to get back to and finish this project series. I just haven't had time with everything I have going on.

[@willch1987]

Hello Peter, have you been able to finish this fixture and run production parts on it?

[@EdgePrecision]

A while back we had a hurricane here in Houston. Our house got flooded. We were actually living in my son in laws house for almost two years while our house got repaired. Fortunately the garage didn't get enough water in it to damage any of the machines. But because (I think) of the high humidity and my lack of (for two years) me not doing anything with the machines in the garage. When I turned on the Haas mill after all that the 4th axis (The rotary A axis you see in the thumbnail of this video) did not work. I suspect it is a frozen break cylinder. I have had this happen on other Haas rotary tables. Up till now I have not been able to spend the time to correct this issue. As well the Renishaw tool setter has a problem. It gives a alarm if I command a tool probing cycle, saying probe open. I think this may be a wiring issue. (This is a older wired in probe not a newer wireless one). I need to correct at least the A axis issue to continue with this project. It looks like I may have time coming up to be able to do this. I would like to finish this setup. I already have enough material to complete 40 of these stop assemblies. I could be a good little side product for this channel. Thanks!

[@willch1987]

@@EdgePrecision thanks for the reply! I remember the flood and hearing you mention this was on hold a while back, just wasn't sure if you had started back on it since. When you have the time again it would be awesome to see a video on the next steps and finished setup if you're willing

[@HomeImProveMentHow]

Well then you make this look simple thank you for sharing God bless By4Now Ken

[@pitu72ger]

Hi Peter, seems the shaft is axially fixed at both ends when clamped to the 4th axis. If that is the case - does it not need any movable bearing when the aluminum holder expands under heat. Probably I overlooked something. Thanks for all your excellent content.

[@EdgePrecision]

In use the fixture just holds the smaller parts being machined. There should be very little expansion if any due to heat. Also there will be flood coolant cooling everything.

[@pitu72ger]

@@EdgePrecisionI got it, thanks for your reply.

Yes I think I have two of them. I bought them when getting some welding supplies and videos from his store. His KZbin channel is one of the best to go to for welding information.

[@micahhunter2706]

yes, he has the best welding channel, by far. I was lucky enough to meet him last November at FabTech.

[@MrSpad007]

One must thoroughly clean new bearings before packing them with grease or the shipping oils will make the grease run away from the bearing surface and cause premature wear. Proper hand packing takes practice and that is why they make bearing packers. i see that this is a extremely slow speed application so no real worry but one might show best practices. Great work Sorry about the lubrication NAZI stuff

[@EdgePrecision]

MIKE BASFORD you know I didn't know that. That's good to know. The only reason for this type of bearing is to preload them for no play. I would be surprised if the rotary table could turn any faster than 60 rpm. I will remember to do that in the future. Thanks.

[@MrSpad007]

Your welcome.The shipping/storage oils or even Cosmoline is for rust protection and shelf life. It's really horrible stuff . And from some Countries unknown perseverative and not very good at that. A few years ago i had a time convincing the RepRap/prusa community to wash bearings and smooth rods before lubing (also low speed applications) for the linear bearings i sold back then. i found this channel watching a guy in Finland .

[@alessandrobrogli5141]

You are a monster!!

[@akfarmboy49]

did you make video running the quick stops

[@Jraksdhs]

How did you light that torch when heating for the shrink fit? And I didn't see you turn the gasses off at the torch?

[@EdgePrecision]

Jason Raksnis in the gas lines coming up to the torch is a valve called a gas saver. The gas saver has a lever you hang the torch on that shuts off the gas. It also has a pilot light to lite the torch once you pick it up. With this you can leave the valves adjusted on the torch and just pick it up off the lever. The gas turns on and you light it with the pilot. When your done just hang up the torch and it shuts off the gas. The torch goes out. Hence the name GasSaver.

[@cnc-ua]

Great. I can't find the next video. Am I missed anything? Or the project is on hold?

[@EdgePrecision]

I am doing this in my garage at home. Since the flood here in Houston Texas (you may have seen it in the news). I haven’t yet been able to move back into my house. I’m staying at my son in laws. It some what problematic to go to my house in the evenings to work. His house is in a different direction. With the traffic in Houston I would be spending a lot of time just driving. So for the time being it been on hold.

[@cnc-ua]

Edge Precision yes, I know the news. I thought you already recovered. I wish you to move back to your home asap

[@SoWe1]

Shouldn't have the taper been enough to make the piece run true? If you're using adjustment screws anyways, why the taper?

[@EdgePrecision]

SoWeMeetAgain the back plate is like the one on a set-true chuck. It mounts on the spindle first than the fixture mounts to it. Than the runout of the fixture would need to be adjusted after with the set screws. Just like a set-true chuck.

[@SoWe1]

@@EdgePrecision thank you for the answer, but I'm not getting it, since english is not my first language and I don't have very good machinery vocabulary. But am I right to grasp fgrom your explanation that the runout adjustment screws work on a different piece than the one connecting with the taper?

[@EdgePrecision]

SoWeMeetAgain Yes the backing plate has a turned shoulder that projects into a c-bore in the fixture that the set screws push against to adjust the runout. Just exactly the same as a set-true chuck. In fact the backing plate is the same one used on such a chuck.

[@SoWe1]

@@EdgePrecision thanks :)

[@travl3217]

Pete, is this the last video you posted on this project? I can’t find any video of you marching the rest of this fixture.

[@EdgePrecision]

Yes I haven’t been able to finish it yet. I just last week moved back into my house. It was damaged in the storms flood in Houston. About a year and a half ago.

[@markowen7164]

Was that a high prasisan tap?

[@EdgePrecision]

I'm not sure I understand your question.

[@markowen7164]

Just joking with you Peter. I was referring to the out side tap. You call a forset I think. You do really amazing work. Best regards Mark.

[@policebox1092]

very good fixture~!

[@rs4race]

Would it be better to add shims between the bearings to preload them?

[@EdgePrecision]

As you say it could be done. With angular contact bearings (a matched set) this would be a good way. With tapered roller bearings it seems the traditional way is to use a adjustment nut so that's what I always do. Using shims you would need a accurate spacer to take/limit the force of the shim stack (as you tighten the nut) between the bearing cones this would require a extra piece to be machined. It would probably be better but would require more precise machining and fit up. For this low speed application I can use a higher preload on the bearings for extra rigidity. I need to get back to this fixture its been setting on the mill half machined. I just haven't had time. Thanks for the comment its good to see someone still looks at these older videos.

[@localele1]

Nice work as usual Peter. I know you grind your own cutters but roughly what are they worth for something like that step drill/countersink?

[@EdgePrecision]

That size of tool, I could do for about $80.00 coating would be extra.

[@cruch9]

How are you shutting torch off so fast and then relighting it so fast?

[@EdgePrecision]

There’s a valve you can buy called a gas saver. It has a arm you hang the torch on that turns off the gas. It also has a pilot light to lite the torch. So you just pick up the torch light it on the pilot’s flame. Search it on the web you will see.

[@aus71383]

I know it's been 15 months....but it sure looked like you forgot to put that seal in under the first bearing when you were assembling it with sealant.

[@EdgePrecision]

The seal is there. I didn't show this to clearly in this video Thanks.

[@nilzlima3027]

at abute time stamp 22:00 you are checking the horizontal alignment of the fixture and the last inch or two is as you describe "1/2 thou out" might that be from the press fit of that part in the end of the fixture?

[@EdgePrecision]

I’m not sure. I made this video a long time ago. I will have to review the video and get back with you.

[@nilzlima3027]

i ask as more of a GP question if an internal press fit would effect the OD of a part like that. it seemed that the rest of the cylinder was true and just the end that was off.

[@EdgePrecision]

The shaft is a shrink fit so it could very well have distorted the part.

[@zoltanvacsi5135]

it will remain big, or stay the size

[@Meeky815]

This is my garage at my house. I purchased these machines after I sold the large shop. I had in mind jut to fool around in my garage.

[@EdgePrecision]

+MrLiamCooley I like it. It's a nice little machine. I have been running on single phase power. It only has a max spindle speed of 4000 rpm (this may be different on newer ones). That's a little limiting for a small machine. The machine runs good I haven't had one single problem with it.

It didn’t get any damage but the house still isn’t repaired to where we can move back in. I was doing that in the evenings in the garage.

Believe it or not we are still not back in our house after the hurricane. It is difficult because of traffic in Houston. The place we are currently staying (My son in laws) is in a different direction from my shop. So I haven't been able to do anything further on the mill stop project for now.

I am sure that if you were to make more stops there would be many people who would want one.
