Hahaha I was watching part 3 when you were taking the first few facing cuts to clean up the old weld and commented on how far that whole face was running out and I thought 'hmmm Keith isn't going to be happy with that on one of his jobs he would want to face that right across to true it up' and here we are at part 4 facing cutting those two faces to true them up! Mr Fenner you are an inspiration!
I hit on your videos by accident and have totally enjoyed your calm and instructive procedure and sent the link to my boy. we have a small lathe and mill with very limited experience and have learned a lot, can't wait to get to the next video as I watch. thanks ED
i and im sure alot of others really appreciate you taking the time to fill these for us, really entertaining when its to cold to go out to my garage and work on my own projects, thanks
This is a great series Keith. They're all good. Sorta like a Playboy calender. They're all good; some a gooder! I really appreciate the time and effort you put in making these. Regards Dave
Thanks for You spending the Time 2 make these Video's. I drove a Shaft out of a BronZe Impeller today at my Job. I work with my own Projects @ home also. I am gaining Knowledge from your Video's Thank You
What is so satisfying is seeing you do so much "old school" techniques that I used to do - sometimes wondering if I did OK - seeing as I was self taught. So good to see you work so diligently - if I had your machine shop I think (tho pretty much retired now) I'd be working just like you. So many odd ''tricks'' - we both use the same. Great!
Another amazing video series. I am only a hobbyist so am in no position to offer advice really! But a tip I picked up from our friend TubalCain (MrPete) is to use 2 chuck keys when working with the 4 jaw. Maybe it's not practical with your mammoth chuck, but I've found it really beneficial. All the best for 2013!
You could have made the shaft .001 larger then hole in the ring then put the ring in an oven to expand it then slip it over the shaft. When it cooled off you would never have to worry about that wobbling on the shaft ever again. Great video, awesome of you to share your skills.
Yeah the hole in the flange does look to be small by eye compared to the shaft. I think because your eye compares the hole to the outer diameter of the flange which is much bigger. The shaft is bigger in the middle but the 3" ends are not that much smaller. That press fit worked out really good, you had to be pleased with that.
Superb videography, especially the close-ups of the chips forming on the insert! This may be your best vid yet. I sure hope you checked to make sure the flange is facing the correct end of the shaft! It's obvious from the way you finished that shaft that you know that Colchester very, very well. You did a great job setting yourself up for hitting the number on the final cut. It will be interesting to see how much distortion the welding causes...
I I have forgotten now around 27 ton I think, In the videos Press Talk 1 & 2 I give all the details on it and show all the goodies I made for it so far! ;{)---
YOU MR KEITH FENNER KEEP MAKING GREAT VIDS I SELL AUTO PART IN AUSTRALIA BUT LOVE WATCHING OLD TIMERS SPREAD THERE KNOWLEDGE. MY GIRLFRIEND LOOKS AT WHAT IM WATCHING AND THINKS ITS SHIT ... IF ONLY SHE KNOW ... KEEP UP THE GOOD WORK MATE
Hobby machinist here. As I watch your videos, I repeat 2 phrases. 1. So that's how you do that... 2. No wonder that never comes out straight for me... LOL
LOL Loved the comment on how you wished you had taken it a little easier when you were younger. I'm an electrician and in my younger days I was known as the human fork lift!
I recently found a greetings card that had: "When you're young, anything goes" on the front page and on the inside it had: "When your older, everything goes" - with little call-outs for the creaky joints, etc! I didn't have anyone in mind when I bought it - though it applies to me - I was just taken up with the cleverness of it. I know, I'm off topic, sorry!
Hey Keith, you ever think about making a clamp to go on the end of your press shaft that a hook and strap can be mounted to? Shure would saveyour back when you have another heavy long object to pull out!
Just started watching this one Keith, stopped at the 34 second mark to say this: very, very sound call on choosing to go ahead and cut the wobble outta the faces and make them run true. That's really an engineering no-brainer. The chipper drum freaking wobbling, rocking and rolling back and forth like a wet noodle like it may have been doing may have done more to break the original shaft than that ludicrous tenth of an inch of 'clearance the shaft had with the hub! O__O
Great video I hope the flange is facing the correct way What camera are you using If you are running it on full auto the results are astounding Your editing is getting better with every video
Just love the handheld close-ups you put in this video! May I ask the size (tonnage) of your press? Thanks again for sharing you knowledge and skill in these many videos! Best wishes for the New Year! Roy
I really like T-15 HSS for roughing down welds and mill scale, or Tantung bits if you can find them. Both are basically impact proof and last a long time in the cut. Its the best of both worlds, tough cutting surface AND a positive geometry. If I send you a blank would you try it out and report online?
It's never a bad idea to leave a small witness mark on a repair like this... I think there may be noticeably smoother operation on that machine when they go back to using it! I appreciate the extra bit you are willing to go to make the job all that it can be! :o] O,,,
Great video's, I was a heavy equipment mechanic and machinist until i destroyed my back doing just what you are doing, be careful with that lifting, as we get older and look back at all the things we did" well it is then to late to go back and change things. You need to make a small hoist on the press for lifting and lowering heavy parts to the floor. Take care we want to see more of thees great videos.
Thanks for the comment, cool idea, I am thinking swinging davit, only because of the need to carry the load out just off the edge at times with large jobs also. ;{)----
I was thinking you would leave the shaft a little larger on one end to have a tapered stop to press it against. That part is probably made in a jig, hence the clearances. The plate is welded on, then the shaft and plate are machined to the final dimensions so they don't have to worry about warping from welding.
I made it! In one of my videos, not sure which one, shows how the legs swivel to weave inbetween the machines, so it becomes usefull anywhere in the small shop. ;{)---
Hi keith. Another great video. I have a question. I recently purchased a small lathe for my shop. I made a boring bar and holder for it. I would like to make a video and have you take a look and to get your opinion on the fabrication. What would be the best way for me to get the video to you. Can I post it as a response to one of your videos or some other way because TH-cam does not allow links in the comments section. Thanks again and keep making great videos please.
It would be nice to see where this stuff is used now that it's finished and running much more true than before the breakdown - is that posible ? ... "on location reporting" - just when you were in the church tower - I would love to see this monster spinning round.
Hey Keith, I am curious why you didn't cut the keyway on the end of the shaft before the press fit. Which IMHO is how the darn thing should have been made in the first place.
Hi Keith. Have you ever tested running a insert without cutting fluid for its entire lifetime to see how much shorter lifetime it gets? I guess you might get a little worse finish as well. Just curious how much difference it actually makes. And do you monitor the lifetime of your inserts to see witch ones are the best?
Suppose Vermeer work on the basis of :- Flame cut an oversize bore and assemble onto the shaft, square the flange with the shaft and weld it on a rotating welding machine to save time, but obviously the weld has distorted / pull the flange off square.
What type of gantry crane do you have and what is the weight limit? I might have some time this week to dis-neglect that Voest sitting in the garage...Keep em coming.
Hi Keith. I have some 10" diameter discs of 1" thick steel plate which I have to turn down to around 8". The tool (carbide insert) seems at about its limit with a .050" cut at 250 rpm. Could you please suggest how I might speed the job up; bigger cut and slower feed or smaller cut and faster feed?
Hey Keith, I'm sorry if this has been answered (a few times) before, but what camera do you use to produce these videos? I'm in the market for one, and it seems yours has amazing focus control as well as standing up to the harshness of a machine shop!
Yes and it makes enough difference! In my line of work I cut into some of the nastyest crap sometimes, so my insert counting would not give any production figures. ;{)---
Hey Keith, at 20:06 you said that it's 'coarse.' True to your word, when you run your hand across the piece, it sounds like fingers on guitar strings (which are wound and not really all that smooth.) so if you had to make this part really smooth, how would you do it?
Re the comment of having two chuck keys ... that would mean that you leave one of the keys in the chuck while you adjust the other. Whoa! You NEVER leave chuck keys in the chuck when you are not using 'em!
To me most of the time slower and heavier feed rates pull the material off faster, but when you reach the sweet spot on your lathe and tooling, that's where the phrase comes from; metal only comes off so fast. ;{)-----
Did you ever see a cold air gun, I use one on the Bridgeport and it works brilliantly, they are not cheap $200+? , but what a job it does for heavy cuts in tough metals without the benefit of coolant, I have always been curious to see if it would work on the lathe, but my manual lathe has coolant so I have not tried it?
was wondering how come you dont run coolant at the point of contact when machining this shaft i always did when i was turning a shaft like this it seemed to keep the shaft from heating up then shrinking after air cooling - just wondering
Forgive me if this is the dumbest question ever but could you have bored the ID of the flange, welded it to the shaft, then faced the flange while it was assembled?
That's sad. My buddy has a Vermeer disc chipper with the Wisconsin turbo diesel.You'd think for as much as that machine costs, you'd at least get a decent build. As I watch this series, my opinion goes further downwards of this company. At least there's one out there that's built properly now though.
The best thing we can see but you never mentioned is absolutely crucial to the balance of this huge wheel come fly-wheel, and I am very disappointed you never said anything. That which is crucial is the mug of coffee! ha ha!
Hi Keith, I can see from a labor point of view why that bore was never machined to a press fit. This machine is probably maybe 10 yrs old? Vermeer thinks thats old enough. Chances are that when it brakes the owner replaces the shaft with a factory (same crappy bore) or even better (for Vermeer) selling a whole new machine! I love what your doing but when I see thru the corporate glasses... they could care less about a shitty bore...
Hahaha I was watching part 3 when you were taking the first few facing cuts to clean up the old weld and commented on how far that whole face was running out and I thought 'hmmm Keith isn't going to be happy with that on one of his jobs he would want to face that right across to true it up' and here we are at part 4 facing cutting those two faces to true them up!

When I watch your videos I can not wait for ending the winter for us to start working in my workshop. Greetings from Poland.
PS. I love yours videos
Thanks for You spending the Time 2 make these Video's.
I drove a Shaft out of a BronZe Impeller today at my Job.
I work with my own Projects @ home also.
I am gaining Knowledge from your Video's
Thank You
Mr. Fenner, you sure are good at what you do. You make it look too damn easy!
What is so satisfying is seeing you do so much "old school" techniques that I used to do - sometimes wondering if I did OK - seeing as I was self taught. So good to see you work so diligently - if I had your machine shop I think (tho pretty much retired now) I'd be working just like you. So many odd ''tricks'' - we both use the same. Great!

All the best for 2013!
Enjoyed a lot of the close up shots. Thanks for the great videos can't wait for the next part.
18:40-18:46 I had to comment on the way Kieth pats his work like it's his baby. Love what you do and you'll never work a day in your life!
You could have made the shaft .001 larger then hole in the ring then put the ring in an oven to expand it then slip it over the shaft. When it cooled off you would never have to worry about that wobbling on the shaft ever again. Great video, awesome of you to share your skills.
This is a really fascinating series. Can't wait for the next one.
Thanks for the answer Keith, I watched the rest of the series and realised that was the case ,
Yeah the hole in the flange does look to be small by eye compared to the shaft. I think because your eye compares the hole to the outer diameter of the flange which is much bigger. The shaft is bigger in the middle but the 3" ends are not that much smaller.

Ah ... it's a Colchester - I wondered! My local machine shop had several Colchesters - the gear levers up on the top give it away.
I I have forgotten now around 27 ton I think, In the videos Press Talk 1 & 2 I give all the details on it and show all the goodies I made for it so far! ;{)---
Thanks for these awesome videos Keith !!
Nice operating Keith!!

25:20 I like the idea of the 5 thou reduction in the shaft leading up the boss, also the high-speed Sharpie!
Hey Keith, you ever think about making a clamp to go on the end of your press shaft that a hook and strap can be mounted to? Shure would saveyour back when you have another heavy long object to pull out!

Thank you Keith!
The hoist that you see at the lathe moves over to the press also, if needed, but I just lowered the table and rolled it out! ;{)---
Great video
I hope the flange is facing the correct way
What camera are you using
If you are running it on full auto the results are astounding
Your editing is getting better with every video
Just love the handheld close-ups you put in this video! May I ask the size (tonnage) of your press?
Thanks again for sharing you knowledge and skill in these many videos!
Best wishes for the New Year!

Great work, practical instruction on all your videos.

A fellow I know says: "there are no old heroes" if you get his meaning
Hi Keith,
Great detailed video, thank you.
Watching a pro work is fascinating.!
You can't send out the videos soon enough.....
Keep the cool vids coming bro.
Thanks for the comment, cool idea, I am thinking swinging davit, only because of the need to carry the load out just off the edge at times with large jobs also. ;{)----
Becuse of the welding and extra materials left on to be able to have a true turning in the end.
Hi keith,
Good thing you have a place to rest that shaft on under your chest or it might have felt a lot heavier!
I was thinking you would leave the shaft a little larger on one end to have a tapered stop to press it against. That part is probably made in a jig, hence the clearances. The plate is welded on, then the shaft and plate are machined to the final dimensions so they don't have to worry about warping from welding.
Makes you wonder if there is any proud producers any more. Let's make is to last the waranty and a day or two...... As allways, GREAT video :)
Do you think vermeer turned this out of the factory like that- what a hack job!
I made it! In one of my videos, not sure which one, shows how the legs swivel to weave inbetween the machines, so it becomes usefull anywhere in the small shop. ;{)---
keith your bad ass love your video's getter done
Hi keith. Another great video. I have a question. I recently purchased a small lathe for my shop. I made a boring bar and holder for it. I would like to make a video and have you take a look and to get your opinion on the fabrication. What would be the best way for me to get the video to you. Can I post it as a response to one of your videos or some other way because TH-cam does not allow links in the comments section. Thanks again and keep making great videos please.

Hey Keith, I am curious why you didn't cut the keyway on the end of the shaft before the press fit. Which IMHO is how the darn thing should have been made in the first place.
Nevermind, I think part four clears it up for me
Great production, is that a factory or shop built press?
Hi Keith. Have you ever tested running a insert without cutting fluid for its entire lifetime to see how much shorter lifetime it gets? I guess you might get a little worse finish as well.
Just curious how much difference it actually makes.
And do you monitor the lifetime of your inserts to see witch ones are the best?

What type of gantry crane do you have and what is the weight limit? I might have some time this week to dis-neglect that Voest sitting in the garage...Keep em coming.
Great vudeo!
On hand tool I use an asortment, Craftsman, Proto, Snap-on, SK, Mac, and a few others and not in that order as far as preference or favoritism. ;{)---
I'm thinking in hindsight, put plate on bar??? Lighter of the two!!!
Hi Keith. I have some 10" diameter discs of 1" thick steel plate which I have to turn down to around 8". The tool (carbide insert) seems at about its limit with a .050" cut at 250 rpm. Could you please suggest how I might speed the job up; bigger cut and slower feed or smaller cut and faster feed?
Keith,
Thanks. What did you do for a gantry crane setup?
Yes, the flange is correct....
Yo Keith! Why not use coolant instead of oil for cutting? It's smoke free...
Cool. Did you make the actual gantry crane or did you buy it?
keith what were the names of the manuals that you used as a reference guide...Thanks and good work...
Hey Keith,
I'm sorry if this has been answered (a few times) before, but what camera do you use to produce these videos? I'm in the market for one, and it seems yours has amazing focus control as well as standing up to the harshness of a machine shop!
Hello Keith, where can I buy that finger that you use to dial in the part from behind?
How much $ is a factory replacement POS? GREAT series bro👊
you got it in the wright way i hope?
Yes and it makes enough difference! In my line of work I cut into some of the nastyest crap sometimes, so my insert counting would not give any production figures. ;{)---
Hey Keith, at 20:06 you said that it's 'coarse.' True to your word, when you run your hand across the piece, it sounds like fingers on guitar strings (which are wound and not really all that smooth.)
so if you had to make this part really smooth, how would you do it?
machine at a slower feed and a shallower cut ...
STRUTH !!!! Flame Cut Bore !!!!!!!!, Vermeer has gone waay down in my estimation !!!!!!!
? wont the demention from the face to the end of the shaft change du to facing or is that negligable?
Its nice to see that the phone rings at the worst possible time for someone else other than me........lol
Re the comment of having two chuck keys ... that would mean that you leave one of the keys in the chuck while you adjust the other. Whoa! You NEVER leave chuck keys in the chuck when you are not using 'em!
Whoa ! - that is slack!
I use a canon power shot and a canon camcorder Vixia ;{)-----
The addict is back! Where is part five?????....lol
To me most of the time slower and heavier feed rates pull the material off faster, but when you reach the sweet spot on your lathe and tooling, that's where the phrase comes from; metal only comes off so fast. ;{)-----
Did you ever see a cold air gun, I use one on the Bridgeport and it works brilliantly, they are not cheap $200+? , but what a job it does for heavy cuts in tough metals without the benefit of coolant, I have always been curious to see if it would work on the lathe, but my manual lathe has coolant so I have not tried it?
Abom uses this and he can vary the amount of coolant and he blows the chips off - nice!
was wondering how come you dont run coolant at the point of contact when machining this shaft i always did when i was turning a shaft like this it seemed to keep the shaft from heating up then shrinking after air cooling - just wondering
Forgive me if this is the dumbest question ever but could you have bored the ID of the flange, welded it to the shaft, then faced the flange while it was assembled?
what inserts are used with a boring bar?
Not enough room in shop to create shielding and it would cramp up the freedoms when playing with all the accessories. ;{)---
that is good to know. dont think i want a vermeer anything now, thanks,
That's sad. My buddy has a Vermeer disc chipper with the Wisconsin turbo diesel.You'd think for as much as that machine costs, you'd at least get a decent build. As I watch this series, my opinion goes further downwards of this company. At least there's one out there that's built properly now though.
heliarche okay
I run the CNMP in that boring bar most of the time. ;{)---
looked like balancing a bicycle wheel a big one (G)
when you say "4 - 300" are you referring to a dimension of 4.300"?
Yes
Appalling build quality. Good thing it ended up in your hands.
So, what the machine at the back of the lathe? (with the hydraulic? lines)
So what's the machine - sorry, typo!
Oh, there's still plenty of beef left there.
The best thing we can see but you never mentioned is absolutely crucial to the balance of this huge wheel come fly-wheel, and I am very disappointed you never said anything. That which is crucial is the mug of coffee! ha ha!
Actually Keith does mention balance and even distinguishes between axial and radial. Suggest paying attention before criticizing.
did you find a made in China sticker anywhere?
27:15 ...IT BEATS THE ALTERNATIVE-!!!
29:58 Alright! :)
You can link a video and II can see it in my box, or send it Email, found on my web site. ;{)----
Thursday night-shift special cowboy job.
Thats why! ;{)---
They have them at MSC direct (dot) com, I show their Starrett model in the What's in your box video the giveaway part 2... ;{)---
Hi Keith,
I can see from a labor point of view why that bore was never machined to a press fit.
