- เผยแพร่เมื่อ 15 ก.ย. 2024
- The Broken Beaver Part Six; A Vermeer 1800-A with a 110 HP John Deere, I Tech Motor W / Turbo, spinning a chipping drum a minimum of 2,000 RPM's and the shaft breaks and becomes three pieces! That would make your woody job go limp! This is part six to a series that fabricates a new rotating unit for the tree chipper, Un wrap, the blankets and getting the shaft back in the lathe, checking out the run out caused by all the welding and how to deal with it! Moving on and setting up the radius cutting with patterns, cut out on the PlasmaCAM, then mounting in the flat pattern support, using the tracer attachment.

Enjoying every minute......random thought of an earlier comment when you said "I will go get my son to help lift"......I bet your wife was happy your son was home......LOL.....
Another night late to bed ,,, just watching you work,, great job, neat tracer set up.
Have to say Keith, that's kick arse quality work you do!
that tracer is awesome! specially when you can use the PlasmaCam to make any pattern you need, very cool tooling!
Yes, form tooling and a lot of port polishing drums! Been there, thats why I showed the large radius tool before hand. The more I use, the new flat pattern holder and the PlasmaCAM to cut the shapes, I'm in heaven! ;{)---
That is definitely the name of that tune on the ol tracer, and the hand work on those radius also! This was so much better than the no QC or QC overlook from the factory they should be ashamed to send that out the door passing a sure failure on to the retail customer. Great work Keith! :o]
O,,,
I really like your tracer. That makes for a beautiful radius!!
You do explain and show your trade without any hesitation… You are a good soul and American Citizen. From your videos I see you attempt do your job to the text book defined perfection and I feel your are a good soul, I am saying this because the way talk, explain,etc... and show how you do your job tells us that you are very good soul. God bless you. We like you....
Fantastic work Keith thanks for sharing...keep up the great work!!!
We're fans out West here at Ventura Boat Doctor. What we would give to have a man of your talents here at the harbor. If you ever long to return to the Cali sunshine...
Got it thanks a ton. I checked out the site, a wealth of information. You are the man!
Really nice and professional good work indeed ......... and expensive !
I beleave the part is used in some "tree-crunching-jig" of some kind - not just for use in the garden back home - what I mean is, there has to be SOLD much cut wood to pay for your time doing this nice job - I long to see the machine doing the cutting with this new well balanced shaft and flange - thumbs up and head down for your skills and experience !
For sure!! I have a TA on my lathe, but your tracer is a lot more versatile!
They also have oldschool radiusing attachments that clamp on the topslide. It pivots a toolbit in an arc by means of a stout handle. They can be set up to do inside and outside radii.
WOW...your customer and those you served before must be very please to see just how much time, effort, and attention to detail to the work they give you.
I really enjoyed watching you put the Radius on it I Learn something new in each video !!! Thanks for sharing the Knowledge !!!
Visual poetry Keith! You are a master craftsman! Thanks for doing these vids, they are fantastic!
Great Series, thank you for posting, i'm a novice with little experience and the little tips and tricks really help when i'm trying to build things. I run a Sand and Gravel operation and have been able to build alot of stuff we would normally have manufactured.
That makes perfect sense. Thanks for all your awesome videos, you are inspiring! I love watching, it's the best reality TV show ever!
Thanks for posting these vid. I learn a lot from watching a true machinist at work.
I really like that tracer attachment! I may start noodling on how to make one here. Thanks Keith
Ah, here it is with the Plasma-Cut-Pattern! Shame on me to ask questions before watching the entire series ;-)
Loved it as usual... can we have some more, please! Part 7!
Thanks for the comment and I was aware of the carbon numbers, sometimes when walking the talk I shouldn't talk LOL. It no worries on my part, because if those who know better, or recognize the mistake I my blurb out, jump in and cause a little discussion about it, we all get a little more tuned into the subject! I’m pretty sure that’s what my site is supposed to be about! ;{)---
Great work once again.
I have had minor incidents over the years, judging major as harming the lathe itself. I have been in the same shop with a fly chuck key that stopped after it stuck into a 14 gage steel back board on the bench behind the lathe. and was running a lathe with my back to a lathe that was mistakenly started in top speed and the shaft grew and pulled loose from the center, whipping in the air like a wet noodle, making me dive for the floor! ;{)---
I would contact material suppliers and ask for Buyers guide, if no results go over there head and get a hold of the manufacture, they sell more materials if people have references on their materials. In the old days they would have publishing once or twice a year. EMJ is my first choice to try!{)---
Thanks for the comment! Yes it is, and represents, the years of sobriety. ;{)-----
You do amazing work. If I had something wrong with my shaft I would bring it to you. :)
love your vids, really can't get enough of them. as i have read from others, i agree and say this is better than tv
Thanks for the comment! That is how you build the experience! ;{)---
Back in the late 60's when balancing a 265 or a 283 cubic inch chevy backyard style was balancing of the reciprocating parts on a set of wood chipper blades. I used the DI to check for vibration afterwards, I didn't have what's in your shop at that time, the attitude was the same.. Get Er Done and nothing breaks. (the old JM Wight Tech., Stamford Ct. grad with honorable shop teachers that showed and told how to do before osha) ( what's a osha? seawater?) got fish?) ;) Good stuff Kieth!
Thanks for the comment, we would have to talk to Northstar Proppeller, thats were I got my leave of absence from! LOL ;{)---
Awesome series Keith! waiting for part 7!
Thanks for mentioning that, I have used those many times, and like the designers that created the mic style thimbles for adjusting the concave settings, the convex was basicly a parrellel with a hole for depth mic. ;{)---
hey Mr. Fenner I was thinking about a great tool to put in the give away box and I think that a good set of dial indecators would help alot since you realy seem to use them alot to check your work. just a thought, keep up the good work THANKS
Thank you Keith!
I was really looking for a taper attachment and was disappointed I was going to have to make one or hunt one down. Then I had nothing to do while waiting for customers to show up, I started to tear it down and refurbish all components removing gumminess and polished the spool valve that controls the flow with the stylist, replacing all O’rings and fluid, mounted it and started playing, didn’t take long to forget about looking for taper attachment! ;{)---
This shaft assembly beats whatever slopped out unit they threw together at the factory.Its a shame to see some of the manufacturing techniques utilized in todays production world.USA stuff has gone downhill,Im only 33 and i can see it when i study historical machine and production techniques..Iam a fabricator/welder for a living and I always go back to what Ive been tought from the old timers and books of yesteryear..Its a shame what some of these big corporations have done to big USA companies thats I've worked for...
I only had 1" bolts and used the nut and washer to take up some of the threading and keep them a little shallower. the washer also aids in spreading the load as you mentioned. ;{)---
Keith...you are an amazing hand !!!!
Hi Sean, I thought you may be directing the question to me, and sorry to say, my shop is not setup in accordance with all the rules & regulations to support an apprentice or even part time help. ;{)-----
I bet that your tolerances are at a near perfect compared to what the manufacturer did when it was new.
Thanks for the comment! ;{)---
Looks great after the welding.
If you did not have the tracer, I guess the only way to do the all those radii on the shaft would be with a form tool?
On one hand I admire his precision and pride but on the other I'm thinking c'mon.... it's going to be hidden inside a wood chipper.
Thank you for your comment! ;{)-----
great video!!
Please turn your radius cutter upside down and reverse your lathe rotation, so it won't dig in at all and doesn't vibrate. Form tool 101 :)
Thanks for the comment ;{)---
Keith on the press at my buds I welded a 3/4 x 2 " wheel stud onto the side of the tip by the cyl. then you can lift shafts out with the Hyd cyl . as it lifts up his has a 3" tip pad though ; I did`nt see if you had one on yours , If your worried about losing internal applications make a collar that sits above the tip that bolts on ,the just use the nylon choker to lift it up , Geez some big milling I watched 6 vids tonight on this .+ it working that`s big BIG STUMP ,I live for this 30+yrs to
My lathe only spins up to about 1100 or so, but the ballance of the unit is when all components are assembled and I couldn't swing that big drum! ;{)---
You are a strong man ( super man)
Ooh! You've got a pattern maker! - jealousy is a curse, ain't it?
I'll be covering entry for the give away in the What's in your box videos as they are published. ;{)---
Very nice
Do it once do it properly
Keith, you mentioned harmonics. I once got an automobile rotor returned to me from the shop that resurfaced it and it had a herringbone crosshatch on the surface that contacts the pads. I had never seen anything like it and the shop owner said "Don't worry about that; it won't affect performance. After installing them first time I hit the brakes the whine sounded like a fire truck siren. I took them back to the shop and the next time I got them back they were smooth and shiny. Any idea what may have caused a crosshatch like that to be left on the surface of the rotor?
love the operations joke
Great vid and nice work, Keith! Tell me, when you were shopping for a lathe, was a tracer attachment on your list as a "must have" accessory? Did it come with the lathe, or did you purchase/fit it afterward?
I guess answers a previous question of mine (what's that with the hydraulic hoses ...)
You should find a way to mount a welding lense to your camera for those close up welding shots!
Nice work Keith. Where can I get a book of materials similar to what you are using
Taking material off the outer regions of the wheel will reduce its moment of inertia very quickly.
It came with the lathe but looked like a pile of! ;{)---
Thanks Keith! Were you specifically looking for a lathe with a tracer or did you just luck out?
Next please :) (you should just have a live streaming webcam ;)
On the pattern attachment, why did you have the hex nuts and second washer? Was it just to spread the load wider?
if you want to know what kind of vibrations you will have why not spin it at 2000 rpm in the lathe ? or is this lathe not capable of making 2000 rpm ?
Question : Would it be a good idea to send the whole thing off to a driveshaft guy to get it balaced with the cutters mounted. Heavy thingey at 2000 rpm...... You'r doing a great job on this shaft and it's a shame to have it off balance when running. Just a thought.
If the complete job was done in house, every shop that I have been part of, would have sent it out for balance. I do have to say standing next to it while running had no vibration at all. Thanks for the comment! ;{)------
Keith Fenner I followed the whole process and the work is just great and I bet it runs as smooth as nothing else. I was thinking of the complete thing with the blades on and bearing life :) Every shop I worked in would allso have sent it off for balancing :)
Keith Fenner mhjjeee
the hheehebvv
+Eric Hope Driveshaft guys spot weld weights to the shaft .Probably not good in this application. Plus driveshafts are much lighter.
A lot more than if you were able to buy one off the shelf or find one in a junk yard, then rebuild it. ;{)-----
ever had any major incidents in a lathe?
you know the picking order already! ;{)---
Almost cool enough to hold part 23:20 made me laugh :)
what a rush that was i bet ,,,,,,,,
what rpm is that ?? i notice it on many of your videos/is it a common speed ????
what was the material of that work, hardened steel ?
I do not understand why you do not place four good tachs on something before you start welding, I saw you do this before but told myself someone like you would never do that, I was wrong. If I did that when welding pipe everything would be as crooked as can be.
Regards, Edgar
I think it's because he had a two thousandths press fit on the shaft.
Last 2 digits in SAE numbering is C by weight in 1/100's of a percent, not 1/10's. You've got it wrong. If that's what you're really thinking; look it up, please. So I guess the moral of the story is that we all make mistakes, especially when trying to make hours and hours worth of free helpful videos while doing a paying job, and we can all pick on minor errors to make people look bad, but I guess you wouldn't know that unless you had done as much to help people as Keith.
...and a laser (?) or plasma (probably) cutter
I am a mechanical guy and i actually studied machine shop tech and after 15 years i really wanna hone my skills in machine shop work, Could i do internship at your shop for a couple of months
Wrong radius, inside radius vs outside
first!
love your videos!!!!
It creates a less tendency to want to suck in on you! ;{)---
He didn't buy it from Vermeer because He did not want the shaft.....:) Yea..Should of Spot weld 6,12,9,3 O,Clock....Nice Job ..Rich...3,000.00$ Job....
